26 Chapter 2 Setting Up an Aperture System
Configuring Mac OS X for Multiple Displays
If your computer is connected to two displays, you can set them up to show a
continuous desktop that extends across both screens. This is known as extended
desktop mode.
Because Aperture controls the second display, you must keep your computer in this
mode for the application to operate properly. If you work in mirroring mode, where the
same contents appear on both displays, Aperture may not work properly.
To exit mirroring mode:
1 Choose Apple (K) menu > System Preferences.
2 Click Displays, then click Arrangement.
Note: If the Arrangement button does not appear, click the Detect Displays button. If
the Arrangement button still does not appear, make sure the second display is properly
connected to your computer. For more information, see “
Setting Up Your System with
Two Displays ” on page 23.
3 Deselect the Mirror Displays checkbox.
After you connect a second display, your displays may show the arrangement of the
desktop out of order. For example, the display that shows the hard disk icon and menu
bar is typically on the left, so that your desktop extends out to the right on the
rightmost display.
To rearrange the position of the displays:
1 Choose Apple menu > System Preferences.
2 Click Displays, then click Arrangement.
Note: If the Arrangement button does not appear, click the Detect Displays button. If
the Arrangement button still does not appear, make sure the second display is properly
connected to your computer. For more information, see “
Setting Up Your System with
Two Displays ” on page 23.
