If you need to, you can also relaunch the Finder from this dialog.
Next, save your work in any open applications and restart the computer to make sure
the problem is entirely cleared up.
If the problem occurs frequently, choose Help > Mac Help from the menu bar at the
top of the screen. Search for the word “freeze” to get help for instances when the
computer freezes or doesn’t respond.
If the problem occurs only when you use a particular application, check with the
application’s manufacturer to see if it is compatible with your computer. To get support
and contact information for the software that came with your MacBook Air, go to
www.apple.com/guide.
If you know an application is compatible, you might need to reinstall your computer’s
system software. See “Reinstalling the Software That Came with Your MacBook Air” on
page 46.
If your MacBook Air freezes during startup, or you see a flashing question mark, or
the display is dark and the sleep indicator light is glowing steadily (not in sleep)
The flashing question mark usually means that the computer can’t find the system
software on the hard disk or on any disks attached to the computer.
 Wait a minute or two. If the computer still doesn’t start up, shut it down by pressing
and holding the power (®) button for about 8 to 10 seconds. Disconnect all external
peripherals and try restarting by pressing the power (®) button while holding down
the Option key. When your computer starts up, click the hard disk icon, and then click
the right arrow. After the computer starts up, open System Preferences and click
Startup Disk. Select a local Mac OS X System folder.
