Mac Screen Capture Tricks

Capturing screen of Mac is not just limited to keystrokes Command-Shift-3 alone to capture the whole screen. Some may feel unnecessary to know many screen capture tricks. Some feel the urge to explore more of this nifty screen capture features.

As I've experienced, I found out many practical screen capture tricks, such as Screen Capture Part of Screen, Screen Capture the Screen Saver and many others.

If you've followed UsingMac for quite a time, you will find that I've mentioned some of the screen capture tricks in my previous articles. Here, I will add more tricks, along with the old tricks, to provide more complete and useful resource.

Before going further, you can take a look of other resources related to Screen Capture:

1. Take a Snap of Screen Saver
2. Screen Capture a Window
3. Take Screenshot of Entire Webpage

Let's get started!

Snap Whole Screen

As stated above, you can use Command-Shift-3 to take capture the whole screen; If you've your display set to 1280x800 then you will get a snapshot with that dimension.

Normally, the captured screen will be stored to your Desktop. This will eventually clutter up your Desktop, we can either save the captured screen to Clipboard (by adding modifier key Control) or save to customizable place.

Capture Selected Area Only

Capturing the snapshot of selected area is the most useful feature of screen capture. This feature also differs Mac Screen Capture from Windows Print Screen.

Keystrokes Command-Shift-4 is used to change the mouse to crosshair form before screen capture area can be drawn. Flexibility is given to Mac users for drawing the screen capture area where Mac users can use several modifier keys for different functions, as follows:

1. Spacebar to move selected area
2. Shift to resize selected area either horizontally/vertically
3. Control to resize selected area without moving upper-left pin point

Note: Selected screen will be captured upon mouse-up.

Snap Single Window/Object

If you press Spacebar after pressing Command-Shift-4, the initial crosshair pointer will change into camera icon. In this mode, area of the snap will be narrowed down to hovered object, including the shadow.

If you want to remove the shadow, you need to execute this command line using your Terminal:
defaults write com.apple.screencapture disable-shadow -bool true && killall SystemUIServer

Note: Change -bool true to -bool false to enable the shadow.

Capture Screen Saver

If you've realized, I used snapshots of my screen saver for some previous illustrations. Maybe some tried to snap their Mac screen saver but to no avail as the screen saver will be exited by any keypresses.

Special steps are required to do it:

1. Open Menubar: Apple → System Preferences
2. Go to Desktop & Screen Saver
3. Select your screen saver
4. Hold down Command-Shift and click on the button Test
5. Now you're previewing your screen saver, press 3 whenever you want to snap the screen

You can also use sticky keys to do the trick.

Note: Actually it's the same as pressing Command-Shift-3, but the order is reversed to avoid being exited from screen saver mode.

Grab the Screen

Grab, come along with installation package, delivers the same service as your system screen capture with several additional features:

1. Timed Screen
   Menubar: Capture → Timed Screen (Command-Shift-Z)
   The timer will count up to 10 seconds before the selected area/screen is snapped.
2. Mouse Pointer
   Menubar: Grab → Preferences… (Command-Comma)
   Only using Grab you can capture your mouse pointer. If you insist on using system screen capture, you need to 'photoshop' the snapshot and put the mouse pointer in.

Grab can be found inside Finder → Applications → Utilities.
