New to Mac: Catalina Edition

Untitled Document

David Cox: If you are brand new to the Mac or you’ve
just never had anyone walk you through the basics then be sure to stay tuned. My New to Mac Class Catalina
Edition coming up next on Tech Talk America.




Hey, folks
and welcome to the class today, I have put together a class to walk you through
all of the basics of using a Mac. Now, before we begin we do have a couple of
quick items to go over but don’t worry I’ll keep this part brief. There is a
free PDF guide that goes along with this class which includes a list of all of
the most important hotkey combinations and you’re especially going to want to
download that if you’re coming over to the Mac from a PC. Trust me it’ll help
make the transition easier. The link to that guide is down below in the
video description.


class took a lot of time to put together and assemble and I greatly appreciate
it if you please not use an ad blocker, not just when watching my videos but
also anyone here on YouTube. The reality is that this is how I’m able to
offer content free to the public.


Last item
before we begin this class, I loved getting to make these videos for all of you
but unfortunately the space where I create all of this content has become
increasingly difficult to work in for a variety of reasons. So, I’ve set a goal
to move sometime in the next year to a slightly larger space where I can more
comfortably create content like this for years to come. So today, I’m asking if
this or any of my past classes have helped you over the years, I would really
appreciate your support and I invite you to contribute whatever amount you like. Ask someone who considers himself to be more
of a teacher than a YouTube personality. I can tell you that it means a lot more to
me that someone cared enough to make a contribution rather than
how much they gave, although there’s probably a tipping point at some point. If you’d like to support my channel you
can contribute through [email protected] If you prefer PayPal there is a
link down below or if you’d like to send a good old-fashioned cheque in the
mail the PO Box address is right there. It’s also listed down below in the
video description. Thank you for allowing me to do what I do
for a living and without any further ado let’s begin the class
and switch to my Mac.




I always
like to start my New to Mac class by going over the basics of navigation,
starting with Finder. Now, despite the fact that it currently says
Finder here at the top left of my screen. Please know that Finder is actually this happy
and quite content little Mac icon here at the bottom left. Clicking on Finder
will open what we call a Finder window which will allow you to navigate to
different locations on your computer like your documents folder, download
folder, applications, etcetera.


when I’m working with clients of mine who are brand new to the Mac, one of the
first things I like to do is help them customize what locations appear here on
the sidebar. To do this let’s actually click where it does
say Finder here at the top left and let’s click on where it says
Preferences. Here, under the
general tab, I tend to recommend that you change this option to whatever
location you need access to the most and in my experience for most people
that’s either the Documents folder or the Downloads folder.  Now, let’s
switch over to the sidebar tab here at the top. Starting at the top of the
list, I have checked the boxes next to recent files which can be really handy
anytime you’re trying to find something that you either recently downloaded or


The next
option here is called airdrop which I absolutely love. This feature is perfect
anytime you want to share anything from your iPhone, iPad or Mac with someone
else’s iPhone, iPad or Mac that is if they are physically with you. It’s
perfect for photos, videos, etcetera.


The next
option is for applications followed by downloads. You can comfortably leave out
these next few options for most people that is. We’re going to check the box
next to this house icon which is called your home folder it’ll have your name
on it. The next three items that you see will only
be here in this group, if you are signed into iCloud and if you have
enabled iCloud Drive which I do recommend. As we get towards the bottom of this list
you can now see the three items that I do have checked those are just
really handy if you ever need access to them and I’m going to leave the
rest of these unchecked. I’m going to
close this window by clicking the little red dot that you see at the top left
of this window.


By the
way, on most windows, you will notice a red yellow and green dot at the top
left. The red dot will close a window, the yellow
dot will minimize it down here into the dock which we will talk about
momentarily and the green dot can actually do a few different things. If you click it once, it will take you into
full-screen mode which I use all the time. However, if you hover your cursor
over the green button you will see a few other options appear including
split-screen view where you can then click on that and another application in
order to use them side-by-side or if you have an iPad, you can now use a new
feature called sidecar to use your iPad as a second monitor. The only reason
why my iPad isn’t showing up is because I currently have my iPad connected to a
different Apple ID so that’s why it doesn’t show up there.


There is
actually one other little Finder window related preference that I want to
recommend that you enable. To set this up you’ll need to open a Finder
window, once again by clicking on that little happy
Mac icon. From here I’m going to go
to the very top of the screen where it says View and the two settings are right
next to each other. They are Show Path Bar and Show Status Bar. So, now that I
have those both enabled. If you look here at the bottom of the Finder
window for one, I can now clearly see how much free
space I have on my Mac, which is always a good idea to know and we can also
see very clearly wherein the computer we currently are.


Let’s now
talk for a moment about this bar of icons that you see at the bottom of my
screen. This is what we refer to as the dock. You can customize your dock so
that it contains shortcuts to all of the applications also known as apps that
you frequently use. Like for example, the photos app, the mail
app and the brand-new podcast app. So, let’s say there is an app that you want
to add to your dock that you currently don’t see listed. If you already have it
downloaded whether from the App Store or the web, at this point, you’ll just
need to open up a finder window and then click where it says applications.


So, for
example, if I want to add the app Malwarebytes to my dock I can just click and
drag the icon from the applications folder and drop it on to my doc and it will
stick there. Now, if there are apps on your dock that you
don’t use that you would like to remove there’s a couple of different
ways that you can remove them. The easiest is you can just click and drag
it off of the doc and drag it towards the top part of your screen. Once you get to around 2/3 of the way up
you should see the word remove appear and at that point if you just let go of
your cursor it disappears.


The last
item here at the end of your dock is the Trashcan, this is where you can drag
and drop files once you’re done with them. You can have your trash empty
manually or automatically. If you want to do it manually just click into
it and you’ll see the button to empty it, here at
the top right. Or if you want this
to happen automatically, here’s how you do that. You’ll first need to go to the
Apple icon at the top left and then go into where it says about this Mac then
you’ll need to click the storage tab, followed by the manage button here on the
right-hand side and on this next window you’ll see the option to have it
emptied automatically right here.


At this
point I want to start to walk you through a part of the Mac known as System
Preferences which is where you can really customize your Mac. Now, I’ve done
this with a lot of clients over the years and so, what I would like to do is
explain only the most important preferences and I’m also going to show you a
few settings that you might want to consider changing away from their default
settings just to make it a little bit easier for you to use. So, let’s click on
the Apple icon here at the top left of the screen and then let’s click where it
says System Preferences. Let’s start by clicking here where it says
Apple ID.


Now, even
I have to admit that there is a lot of terminology in Apple’s ecosystem that a
lot of people find confusing and I tend to agree. So, for example, a lot of
people get confused about the difference between an Apple ID and iCloud. So,
let’s go through those starting with your Apple ID. Your Apple ID is the email
address and password that you use to access Apple services like the App Store,
Apple Music, iCloud, iMessages, FaceTime and more. It also contains the contact
payment and security details that you will use to sync across your Apple


iCloud is
a service that stores and synchronizes your stuff which includes your photos,
files, reminders, calendars and notes with all of your other Apple devices. It’s hard for me to make a general recommendation
to everyone about what settings to use and not use because frankly
there are plenty of exceptions to the rule. But that being said, here is my argument for
why I think it is a good idea to use most of these features. One of the things that we are going to
discuss a little bit later in this class is the importance of backing up your
data so that if your hard drive fails or if you had a fire or a flood or if suddenly
you had to evacuate your home, you want to have a way to get back your data
even if every electronic you owned were destroyed. The nice thing about iCloud
is that as long as you have everything set up correctly, you could literally
buy a brand new computer sign in with your Apple ID and iCloud information and
everything comes back. So, by keeping everything under one umbrella,
you only have one place that you need to go.


there is one exception to the rule which is that personally I don’t recommend
that my clients use Keychain. If you’re not familiar with this Keychain
is the ability to synchronize your passwords from
device to device. Now, some people
may disagree with this recommendation but the reality is that the Keychain app
is literally the only app that has never received a makeover and for the
average human being it’s pretty difficult to navigate. So, if you want to sync
your passwords, I’m just going to give a quick plug to another video of mine
which is all about this app called Last Pass. If you want to watch it there’s a
link down below and if you decide to go with a different solution that’s fine
too. I just encourage everyone to have some sort
of a solution for their passwords that is a little bit more evolved
than a notebook of scribbled passwords.


Let’s now
go back to the main system preferences page which we can do by clicking this
icon right here. Next, let’s go into general settings and one
of the new features found in Mac OS Catalina is that
your Mac can now automatically switch from light mode into dark mode after the sun
sets. I think this automatic
feature is great just because if you’re getting ready for bed, the lack of
those super bright white images makes it easier for your brain to shut down at
the end of the day. If your vision isn’t what it used to be and
unfortunately yours truly is rapidly approaching that point,
there are several things you can do to make the text appear bigger on your
screen, I will go over many of those settings momentarily. This one here is pretty simple. It just makes it so that
when you open up a finder window the items that you see on that left-hand side
are a little bit bigger. So, adjust that as necessary. Another option I wanted
to point out is the ability to add back the scroll bars. So, if you’re not used
to using touch gestures on a trackpad or a mouse this can be a good option.


The next
item here is to change the default web browser. Now, for me personally I’m not
a big fan of Safari so I decided to change my default browser to Google Chrome. Next, let’s go briefly here into desktop and
screen saver. One of the new
features in Mac OS Catalina are these new dynamic desktops. These images will
change over the course of the day to show sun rising and setting. Once again,
this feature is just to help make it a little bit easier for you to get some
sleep at the end of the day. We’re going to skip over screen savers only
because these days there really isn’t a need to have a screen saver, you’re
frankly much better off putting your computer to sleep and we’ll cover that
once we get into the energy saver preferences.


The next
preference pane that we’re going to go into is notifications. Just last week I
was helping my parents with their computer and one of the things that I noticed
was they were getting bombarded by these pop-up notifications and this is how I
fixed it and why it’s in this class. So, if there is ever an app that is just
spamming you to death with notifications usually a web browser. You can just
find it here in this list and turn it off.


The next
item here is internet accounts. So, if you have something like Gmail, Yahoo
or some other type of internet account, this
is where you can enter in that information so that it’ll be saved inside
of your computer. This is also how
you can add your email address so that it works with the Apple mail program
which I do highly recommend.


Users and
groups is a great solution for households where several people use the same
computer. By creating different user accounts for each
person everyone can have their own separate space to do their own thing. One of the things that I wanted
to point out is this little lock icon, you see here at the bottom left. You
will occasionally see this on some preference windows which just indicate that
in order to make any changes you’ll first need to click that lock and enter in
the master password in order to make those changes.


We’re not
going to go over accessibility options in this class but I did want to mention
that if you or anyone you know is living with paralysis or one of the various
medical conditions that affect motor control like Parkinson’s or MS, I do have
a class that I recently produced which is on a feature known as voice control
which allows you to entirely control your Mac using only your voice. If you
ever want to check out that class I’ll put a link in the video description.


Moving on,
let’s now go into security and privacy. One of the preferences that I always
like to warn people about is called File Vault. There are very few times when
Apple and I significantly disagree on something and this is one of them. Now,
this feature is great if you are a high profile individual and I have plenty of
clients who do fall into that category, but if you’re just a normal human being
you probably should consider not using this feature. What File Vault does is it
encrypts all of your data. So, think of this as the digital equivalent
of wearing a 50-pound bulletproof vest while
trying to do your normal day-to-day activities. Well, it might make you “more secure”
it’s also going to slow down virtually everything you do. So, if you do go into this pane and it says
turn off File Vault that would imply it’s currently
turned on. So, if you’re wondering
why your Mac is running super slow to do anything, that’s the reason why. Just
be aware that if you do disable File Vault it means that your computer is going
to decrypt all of your data and that process can take a while. So, you might
want to consider doing it overnight.


Let’s now
go over to the privacy tab and I just wanted to point out a couple of quick
items here. First, for those of you who do have security
concerns, it’s not a bad idea to occasionally go through some of
the items that you see in this list and if you see any apps listed here that you
don’t recognize, you might want to uncheck them. Once again in order to make changes you will
first need to click that little lock icon at the bottom left and
enter your master password.


One more
thing on the topic of security there is one and only one security app that I
recommend across the board to every single one of my clients regardless of how
they use their computer, where they live in the world or what they do for a
living and that app is Malwarebytes. This software protects you not only from
malware but adware, ransomware, fake websites and a lot more. Best of all, it’s
easy to use and it runs automatically. Now, in the interest of transparency, I
am an affiliate of Malwarebytes and they are sponsoring this video which I
thanked them for. But that being said, I’ve been recommending
these guys for years and my policy is I only accept sponsorships
from businesses that I actually believe in. Now, if you don’t currently have Malwarebytes
on your Mac, there is a link to get it down in the video description. You’ll find it on my computer
and even more telling you’ll find it on my parents’ computer.


The next
item is software update and over the last few years, I’ve had to change my
recommendation on this feature. So, here’s the thing. In general, it’s a good
idea to run software updates but the exception to the rule is anytime Apple
releases a new version of their operating system. So, for example, when it went
from Mac OS Mojave to Mac OS Catalina. Well, I know it can be tempting to
download a new operating system the day it comes out. The reality is that many
times there are bugs that need to be worked out and that takes time. So, my
rule of thumb is to usually try to wait two months after a new operating system
has been initially released. I’d also advise you to only upgrade to the
latest operating system if your computer was manufactured
in the last four or so years. Newer operating systems require more resources. So, as a computer ages
it will most likely have trouble keeping up with those changes and the result
is things tend to slow down. I’m not saying you need to get a new computer,
I’m just advising that maybe you consider sticking
where you’re at.


One of
the areas that is so much easier on a Mac compared to a PC is when it comes to
adding a printer or scanner. Just go into this option, connect the printer
to your Mac, turn it on, click the plus button
that you see right here and that’s pretty much it. If your printer is wireless, there may be
a couple of other steps but those are usually all done on the
printer itself. One very quick
bullet point on the topic of printers, there is a lot of junk out there. That’s
reality. If you ever need a recommendation for a new
printer, I want you to know that there is a page on my website called
product recommendations and yes, there’s a page dedicated to printers.


The next
item I’d like to show you is actually a really nice time-saving trick. Let’s go
into keyboard preferences and here at the top, we’re going to click where it
says text at the very top. This feature is perfect for anyone who has
to constantly write the same things over and
over again. For example, things like
driving directions. I know plenty of people who send little cute
birthday wishes that use emojis. If you have to answer customer support questions
and get the same kinds of questions over and over
again. Here we have two columns. One called replace and the other called with. So, here in this left column is
where we will create what I have come to refer to as a trigger phrase. So, when
I type these letters onto my keyboard, it is going to replace those with
whatever I want. The key to creating a successful trigger phrase
is you want it to not be a series of letters that you would
normally use in a row. Otherwise,
you could accidentally trigger it all the time which by the way could be a
really funny practical joke.


thing, while we’re still here in keyboard preferences. I’d also recommend that
you check out the dictation tab. This, of course, allows you to speak into
your microphone and it will attempt to translate
it. I’ve found this feature to be a
great way to initially get an idea out of my head and then I usually go through
and correct any errors.


The next
preference that we’re going to cover is trackpad preferences. Now, obviously
you can skip this part if you’re using a mouse but this is one of the big items
on my list in terms of things I like to make sure that people who are new to
the Mac fully understand. Using a combination of gestures on your trackpad,
you can make your Mac do different things and
what I’m going to do is show you exactly what I recommend to my clients. So, if you’re following along at home,
I welcome you to mirror my settings. If you look at the top we have three tabs
and let’s start with the point and click options. Now, you’ll notice that as I
move my cursor over each of these options, a little animation is playing alongside
it to the right-hand side to demonstrate the gesture. I don’t find that a lot
of people use this first gesture. So, I have lookup and data detectors turned


second, however, is critical. For those of you who have come over to the
Mac from the PC world, you are probably used to
having a left and right-click. For
whatever reason, probably just to make life more difficult on a Mac this is
referred to as a primary click and a secondary click. So for example, whenever
you want to pull up any additional options this is where this feature would
normally come in handy. Personally, I like to make it so that when
I click with two fingers present on my trackpad that is
what triggers a secondary click. But
if you prefer, you can also make it so that that happens whenever you click in
a specific corner. I just want you to know what I mean, whenever
I say the term secondary click. Some people like the tap to click feature
others don’t. For
me, I find that I use this feature more on my laptop but not so much on my
desktop. So, choose whatever feels right to you. Here, we can adjust how much
pressure triggers a click as well as the tracking speed. I also wanted to
acknowledge that depending on whether you’re on a laptop or a desktop using the
Magic Trackpad, some of these options may look a little bit different.


Let’s now
move over to the next tab and here you can see I have the first two options
enabled and the last two disabled. This first option is for scroll direction. So, for example, when I launch a website that
is more than one page, I can just simply swipe with two fingers up and down
to make that webpage scroll. The
zoom-in feature doesn’t work for every application but if you ever need to zoom
in something again like a website you can use this gesture which is the same as
you would use on an iPhone or an iPad. If we move over to more gestures you can
see that I have three of these features enabled, the first is to swipe between
pages. So, once again if you’re on the web and you
want to go back a page instead of having to click the arrow at the top, you
can just swipe on your trackpad from left to right and the reverse if you
want to go ahead a page. 


The next
feature is to swipe back and forth between full-screen apps. For now, I would
recommend that you enable this feature and we’re going to talk about it a
little bit more later on. Finally, we have Launchpad. With this feature, I can
start with four fingers extended and then pinch them inward. By the way,
Launchpad is also the same as this little spaceship icon that you see here at
the bottom of my screen. It basically is just another way to get into
the applications folder that makes it look a little bit like
an iPad. So now for example, if I
wanted to go to page two of my apps, I would just need to swipe with two
fingers left and right to navigate between those pages. By the way, if you ever
want to exit Launchpad, you can just click anywhere that you don’t see an app.


next go into display settings. If you have trouble with your vision this
is definitely something that you’re going to
want to explore. Just know that if
you change this option from default for display to scaled, this will make
everything bigger but as a result, it will also lower the resolution a little
bit so that images may not appear as high definition as they actually are. I’d
also encourage you to go here into night shift settings and set this from
sunrise to sunset. That way after the sun goes down, it will
automatically shift the colors so that the images are warmer,
making it easier for your brain to shut down at the end of the day. That being said there is one exception to
the rule, I don’t recommend using this feature if you are a photographer or
video editor and specifically if you work at night. One time I stayed up late
color correcting one of my droning Provincetown videos not realizing this
feature was turned on which meant recolor correcting everything the next day.


The next
option is a brand new feature in Mac OS Catalina called Sidecar and this
basically allows you to use your iPad as a second monitor. It’s not for
everyone but it’s a really good feature to know about. As I mentioned earlier,
instead of using a screen saver you’re a lot better off to have your Mac just
simply turn off the display after a period of time. One quick side note, if you
have a desktop as opposed to a laptop one little accessory that I do highly
recommend is to have some sort of a battery backup especially if you live in a
part of the world where you get a lot of brownouts or blackouts during certain
times of the year. You don’t really need anything to too crazy. This device is
not meant to be used like a generator. It’s really just so that if the power
does go out you have an adequate amount of time to properly shut down your


Next, I
want to talk briefly about Time Machine. This is a feature where your Mac can
automatically backup to something like an external hard drive. Now, backing up
your data is something that you should take seriously. I am telling you right
now that data recovery is one of those life lessons that you don’t want to
learn the hard way. At this point I’d like to recommend that my
clients have both a cloud backup solution like iCloud or
Dropbox, as well as, a backup on a physical hard drive using Time Machine. Now, the good news is that the cost of
external hard drives has come way down over the last few years. You really
don’t need anything overly special for a backup. Just make sure you get one
with a big enough capacity and one that comes with the connections that fit
your computer. I don’t want to waste any more time talking
about external hard drives. So, if you do need a local backup I have plenty
listed on my website on that product recommendations page.


At this
point, I want to show you how to run apps in both full-screen mode and
split-screen mode. So, sometimes when I’m working on something
like, let’s say, surfing the web, I don’t like to have any
other distractions. So, when I do
that I tend to put my web browser into full-screen mode which you can do just
by quickly clicking and releasing the green button here at the top of any app. Now, if I wanted to navigate back to my desktop,
this is where those gestures on the Trackpad come into play. So, at this point, I would swipe with three
fingers left to right to navigate back to my desktop. Alternatively, sometimes
I like to have apps run in split-screen mode where I have one app on one side
of the screen and another on the reverse. For me, I have found that the mail
program and either the messages app or the calendar app pair very well
together. In order to make your apps run in split-screen
mode just make sure they are both open and then just hover your
cursor over the green button and that will reveal these options. So, at this point, I’ll put this app into
split-screen mode and then I’ll just click over here on the calendar app. Now
that I have these two apps running side by side, I can grab this bar in the
center of the screen and stretch it so that one app has more space than the


make certain types of operations a little bit easier. The most popular is
probably copy and paste. For those of you who are coming to the Mac
from the PC world you’ve always used the Windows or ctrl
key but on the Mac we usually use the command key. So, many of the hotkeys that you may have
learned on your PC are actually very similar on the Mac and rather
than spend extra time going over all of those hotkeys instead I invite
you to download my free PDF guide which lists many of the most popular hotkey


topic I always like to cover when teaching this class is how to tell your Mac
that you want to do something to more than one file. To demonstrate this, I’m
going to launch the photos app. Let’s say for this example, I want to email
a bunch of photos to a friend of mine. Rather than sending one photo at a time,
it will be a lot easier to just include all of them in one message. If the
items that you want to select are not consecutive, all you need to do is hold
down the command key and individually click the ones that you want to
highlight. Alternatively, if the items that you want
to select are in a row, it’s just like it is on a PC. All you need to do is click on the first item
then hold the shift key down on your keyboard and then finally click the last. Now, if I want to email these out, all I need
to do is click the share button, a icon that you definitely want to familiarize
yourself with and then from here, I can share it to email.


handy trick that I wanted to cover in this class is how to use your iPhone or
iPad as a photo or document scanner. Now, this is a fairly new feature and
provided your devices are up to date it’s actually very easy to use. All you
need to do is secondary click wherever you want the file to go. So, for
example, I could do it here on the desktop or another popular option is to do
this while composing an email. As you can see here, it gives me my options
to snap a photo of either a document or just
take a standard photo and when I click this option it now automatically launches
the camera app on my iPhone. For now, I’ll just take a photo of a book
I just finished and there just like that the file appears on my desktop. Pretty cool, huh.


There are
a few features that I wanted to point out here at the top right of your
desktop. Let’s start with Notification Center. Clicking this icon will reveal
Notification Center on the right-hand side of your screen. There are two tabs
at the top, one is called today and the other contains all of the notifications
themselves. One really important thing to know about Notification
Center is that if you scroll down from here, you can
reveal two additional features. This
is the shortcut to manually enable or disable nightshift mode and we also have
an option to turn on or off, do not disturb mode. When enabled, you won’t
receive any alerts or notifications. In fact, if you look at the icon for
Notification Center you’ll see that when I enable it, it gray’s out. One more
thing to know about do not disturb mode, if you want your computer to
automatically go into this mode during certain hours you can just click on the
gear icon here at the bottom right and that will take you to the Preferences. If you look here at the bottom of Notification
Center, you’ll also see an edit button. Clicking that will open up the available apps
that you can place into Notification Center. For me, I really like having my calendar,
reminders, the weather, stock market and I’d like to have
a world clock for each of the different time zones that I commonly communicate


The next
icon that you’ll see here at the very top is Siri. You can use Siri to do a lot
of different things like send text messages, emails, launch applications, find
out information about local businesses movie showtimes and a lot more. Now,
whether or not Siri understands you, well, that’s a different story. Spotlight
is a feature that allows you to search for files on your Mac, websites that
you’ve recently visited, sports scores, weather conditions etcetera.


feature I wanted to give a shout-out to is a very simple yet highly useful
feature called Stacks and this is especially good for any of you out there who
have cluttered desktops. To enable this feature just secondary click
on your desktop and click here where it says use Stacks
and when you enable it, it will automatically organize your files by type. So, for example, I have a bunch of
documents that are now all grouped together and when I click here it can expand
them and then when I’m done I can click it again to close it. See just like
that clean desktop.


I’d like
to end this class by offering you a few additional resources. If there are
other apps that you want to learn how to better use on your Mac, I want to show
you a little trick. If you go to my main YouTube channel which
is, of course, and then if you
click on this little spyglass icon you can type in whatever topic you want and
odds are after 500 tutorial videos you’ll probably find something. I also wanted to take a moment to recognize
that everyone out there learns differently and if you were the kind of person

if this video helped you, you can help other people find it by clicking that
little like button, leave me a comment down below and if you haven’t already
done so, you can also of course subscribe to my YouTube channel and make sure
you hit that little bell icon so you receive notifications when I come out with
new classes. Thank you so much for watching everyone. This is David A. Cox with
Tech Talk America. Class dismissed.
