In-Depth Information
When an application crashes, you usually see a dialog like the one shown in Figure 12.7. Click Relaunch to get
MacBook Air to restart the application for you. In most cases, the program picks itself up, dusts itself off, and
resumes working as though nothing bad had happened.
12.7 This dialog appears when an application goes up in flames.
However, you may find that the program goes down for the count yet again. In this case, you see the dialog
shown in Figure 12.8. Click Reset and relaunch.
12.8 This dialog appears when an application crashes a second time.
At this point in the proceedings, MacBook Air assumes that a corrupt preferences file is causing the problem.
So when you click Reset and relaunch, MacBook Air does three things:
It creates a copy of the application's existing preferences file. This copy has the same name as the origin-
al, with .saved tacked onto the end.
It deletes the application's existing preferences file.
It restarts the application. The application sees that a new preferences file exists, so it creates a new default
preferences file.
This procedure is called Safe Relaunch. If your application runs without mishap now, the preferences file was
the troublemaker all along. Go ahead and type your preferences again. When you exit the application, MacBook
Air displays the dialog shown in Figure 12.9. Be sure to click Use new settings to save your new preferences
file.
