In-Depth Information
Additionally, if you click the program menu and then Preferences, you can
select to include various cursor images within the screenshot (usually cursor
images are hidden when using Grab and also when using OS X's built-in
tools, as mentioned previously). Just select a cursor type you're interested
in, close the Preferences dialog box, and then capture a screen using one of
the menu options as described previously. During the capture process, the
cursor will change to the one you selected.
Grab can capture images only in the TIFF format.
Using Preview
The Mac's general-purpose image viewer, Preview, also has screen capture
abilities built in. The advantage of using Preview is that you can crop, edit,
or annotate the image once captured. You can also save images in a variety
of image formats.
Just start Preview (open Finder, select the Applications list, and then double-
click Preview), click File→Take Screen Shot, and choose from the options.
The captured image will appear within Preview as if it's an image file you've
just double-clicked. You can annotate it by clicking Tools→Annotate. To save
it, click File→Save. Select the image format you want to use from the Format
drop-down list in the dialog box that appears (hold
OPTION
before selecting the
drop-down list to see more file choices).

Ignore a Software Update
In my experience, there's a new update for my Mac every few months or so.
Often this is an iTunes update, and on one of my computers, I simply never
use this software. Therefore, wasting time downloading an update is pointless.
To avoid being nagged about the update, I simply right-click its entry within
the Updates section of the Mac App Store and select Hide Update. This will
remove it from the list.
Should you change your mind at some point, simply click Store→Show All
Software Updates. You might have to quit and restart the Mac App Store for
the update(s) to become visible again.
