How to Set up a Screen Saver in Mac OS X Lion
One of the first things computer users do when they get a new Mac or install a new operating system is set their screen savers. Mac OS X Lion comes with several screen-saver modules. To set up your Max OS X Lion screen saver, follow these steps:
Open System Preferences; click the Desktop & Screen Saver icon; click the Screen Saver tab to see the options.
In the Screen Savers column on the left side of the pane, choose a screen saver option that interests you.
If you can’t decide, you can choose the Use Random Screen Saver check box. This will have your Mac choose a new screen saver at random each time the screen saver starts.
(Optional) To see what the chosen module looks like in action, click the Test button. Then press any key or click anywhere to end the test.
After you’ve chosen a screen saver, drag the Start Screen Saver slider to the number of minutes you want your Mac to wait before activating the screen saver.
If you see the yellow Alert icon below the slider, click the words in blue (Energy Saver preferences), which causes the Energy Saver pane to replace the Desktop and Screen Saver pane. Drag the Computer Sleep slider to a value higher than the number of minutes you selected in step 4. Click the Back button when you’re done to return to the Desktop and Screen Saver pane.
(Optional) Choose the Show with Clock check box to display a digital clock along with the screen saver.
(Optional) Click the Hot Corners button to choose which corner of your screen activates the screen saver and which disables it.
If you enable this option, when you move your cursor to the chosen corner of the screen, you activate or disable the screen saver until you move the cursor elsewhere.
Note that hot corners are optional and are turned off by default.
When you’re finished, close the Desktop & Screen Saver pane.
