First let's start by reviewing the keyboard shortcuts you use to take screenshots. You go
into System Preferences and Keyboard, then go to Shortcuts and then Screenshots. You'll see all of
the options here. Now the first four options have been around for a long time and they allow you to
use a quick keyboard shortcut to take specific type of screenshot. For instance Shift Command 3
will take a shot of the entire screen and store it as a file. But you can use Shift Command 5 to do
any of these four things plus a whole bunch of more options. So it's a lot easier just to
remember Shift Command 5 and it's what I use most of the time. Unless you're taking a certain type
of screenshot all the time it's just easier to do Shift Command 5 than of all the options available.
So when you use Shift Command 5 you get an interface at the bottom of the screen that
looks like this. The first three options here are screenshot options. These are recording options.
So you've got Capture Entire Screen, Capture Selected Window, and Capture Selected Area.
Now you can choose anyone of these and it will remember it for next time. So let's stick right
now with Capture Entire Screen. My first tip is going to be some keyboard shortcuts here
for the next step. If you want to exit this all you need to do is press the Escape key
and it closes it. If you want to take the screenshot then you can go over here and
click Capture. You could also click on the screen that you want. I've got multiple screens on my Mac
so I can actually move this camera cursor to whatever screen I want and it will take
a screenshot of just that screen. If I use this Capture button here it's actually going to give
me all three screens as three separate files. But I could just use Return to bypass having to
use the Capture key. So a quick Shift Command 5 and then a Return will take the screenshot.
Now of course you noticed that it first appeared as a Thumbnail at the bottom right hand corner.
I had to wait quite a long time for it to appear here on my desktop as a file.
A lot of people complain about this and it's easy to skip. It's just a setting.
So let's use Shift Command 5 to get back into this interface and Click
Options. It's Show Floating Thumbnail. If you turn that Off now when I hit Return
it immediately saves the file. So you have complete control over how it works.
Now there are also other options here. Whether or not you have Show Floating Thumbnail on or off,
I'll turn it back on, if you set it to some of these special options it won't appear as
a thumbnail. It will go directly to a specific app, like Mail or Messages. Let's set it to Mail.
Now when I hit Return to capture the screen it immediately opens up a new email message
and you can see the screenshot is there as an attachment. So if sending screenshots in email
messages is something you need to do quite often then you may want to set it to this
as the default. Note that when you change either the floating thumbnail option or where
the screenshot goes it effects the other keyboard shortcuts as well. So if I used Shift Command 3
it will actually do the same thing. Here it's putting it in an email
message which is what I had it set to. So if you want to use Shift Command 3,
but you don't want to have the floating thumbnail, simply set it to Save To wherever you want it
to save and then turn off Show Floating Thumbnail. Now when you Shift Command 3
it immediately saves the document, in this case all three of my screens right here on the desktop.
Now let's take a look at some of these other screenshot options.
In Capture Selected Area or a portion you select that you get this area here that you can move
around, you can adjust the size and the corners to capture exactly what you want. Now sometimes
you may want to just Capture, you can use Return to do that. Other times you may want to adjust
to Go To Clipboard. But there's a trick that you can use. You can actually use Command C right
here. So I have it set to Capture to a File. But instead of hitting return or pressing the
Capture button, if I just do Command C it copies to the Clipboard. So now if I take a look at
what's in the Clipboard you can see I've got that screenshot. It's ready to be easily pasted into
any other app that will accept an image. You can do the same thing with a full screenshot. So if I
switch to Capture Entire Screen I can do Command C and it captures the entire screen to the Clipboard
for me to paste in anywhere else. That works with the Capture Selected Window options as well.
Now speaking of Cropping if you'd rather crop after you do a capture you could easily do
that by using the option Preview here. That will send the screenshot directly to the Preview app.
So in this case let's capture the entire screen and you could see it's going to open up Preview
and open up the capture inside of Preview. Now that I'm in here I could easily select
any area I want and then use Crop or Command K to quickly crop to that area. Now it's in
Preview here I can use Command S or File, Save and save it wherever I want. You could also select
and then Command C to copy an area. So now I can paste it into an email or message or another app.
Now another way to do this is to actually use that floating thumbnail. This is what makes it useful.
So if I have the floating thumbnail turned on and I capture the screen if I click on the thumbnail
there now I can go in here and use this Cropping tool and crop it. It works a little different than
it does in Preview. It looks a lot more like it does in Photos. Crop the area. Hit Done and it
will Save just the cropped portion. So there are a few ways to crop a screenshot after you take it.
Note that the floating thumbnail does have a lot of useful tools in here. Not only can you Crop but
you could do just about anything you do in Preview including annotate it with drawings, shapes,
text, you could even sign things if it's a document. Then you could send it to various
different places right from here without actually having to save the file. If it's
something you don't want, the screenshot isn't of use to you after looking at it, you could
click the Trash button here and it goes away. There's never a file for you to have to delete.
So now let's take a look at capturing a window. When you have this selected and then you click on
a window it will capture the window and put it in a file. Now if we look at that with QuickLook we
can see there's a lot of extra space around it. That's including a shadow behind the window. If
you don't want that shadow you can turn that off but you have to do it in Terminal. So in Terminal
we're going to use this Command which is: defaults write, which will change settings, and the setting
we want to change are com.apple.screencapture, the setting itself is disable-shadow. We're going to
set it to true. Disable those shadows. Then we want to use: killall SystemUIServer that
restarts the system user interface server which is what controls screenshots and displaying
windows and things on the screen. So we'll use that. Now when we go to do the same thing
we'll capture the window again and we're going to get a screenshot. You could see here
that it's got less of an area around it because it's not capturing the shadow.
To turn if Off all we need to do is use false instead of true. I can use a semicolon here to
separate the second command so I can do this all on one line. One simple
paste of this command here and then return and it's set, disable shadow false.
Now here's another preference you can change using the Terminal. Instead of disable dash
shadow we're simply going to change Type. Here you can put three characters that represent the
type of image that gets saved. By default it's a png which is lossless, every pixel is perfect
in the screenshot. But those files can be a little large. If you want to compress it a little bit you
can instead use jpg for jpeg and now it will save screenshots as a jpeg image. So when I capture now
I'll get a jpeg image here. I had previously captured the exact same thing using a png.
If I look at information for the png I could see that's it 5.2 MB and for the jpeg is only 442K.
So considerably smaller. It's still going to do a pretty high resolution jpeg
but it will be somewhat compressed so it won't look as crisp and clean as the png.
Now other values you can use here are gif if you want a gif file and pdf if you want a pdf.
That's actually going to create a jpeg and put it into a pdf document. But it could be useful if you
need to take a screenshot and send it to somebody as a pdf. That's how they want it for some reason.
Then you could save your screenshots directly to a pdf like this. To set it back to the default
just change this to png and now it will return to using png's as the image type.
So a few more tips here. One is if you want the location for your screenshots to be somewhere
beside the desktop and Documents you can choose Other Location. So, for instance, let's go into
the Finder here and let's say my Documents folder I want to create a New Folder and I'll call it
Screenshots. Then I could go in here and choose Other Location. In Documents. I can select the
Screenshots folder and choose it now it will save all of my screenshots here until I change
it again. This is much better than cluttering up your Desktop all the time. It's pretty easy
to change. So if you're working on a project where you want to save all the screenshots for today in
a certain folder you can set it to that and then tomorrow you can change it to another location
to save your screenshots. It's not permanent. You can change it all the time if you want.
Also note that if you take a screenshot and you have the floating thumbnail option turned on when
you capture you can actually take this thumbnail and drag it to a folder right away and it will
place it in there. Now a question I sometimes get is what if you want to capture something, like say
a menu here. If you bring up a menu and want to include that in your screenshot as soon as I hit
Shift Command 5 and then I go over here to Capture it's going to remove this menu. But you can use
the shortcut. Return. You could see it actually captures the menu. Another way to do it that can
capture even trickier things is to use the Timer. So if I go here to Options and set a 5 second
timer and then Capture it's going to countdown. That gives me an opportunity to select some things
in the menus and it will capture exactly what happens when the 5 seconds or 10 seconds elapses.
I've got one last tip for you. You can actually capture the screen of the Touch Bar
on your MacBook Pro. You can't use Shift Command 5 for that. It doesn't appear as an option.
But if you're using a MacBook Pro with a Touch Bar and you go to Keyboard Shortcuts in System
Preferences you see there are two options that Macs without Touch Bars don't get. That's to
capture the Touch Bar either to a file or to the Clipboard. This will obey various settings like
exactly where you want the screenshot saved and all of that. But you have to use Shift Command 6
or Control Shift Command 6 in order to capture the Touch Bar.
Hope you found this useful. Thanks for watching.
