52 Chapter 4 Problem, Meet Solution
Occasionally, you might have problems while working with your MacBook Pro. Read
on for troubleshooting tips to try when you have a problem. You can also find more
troubleshooting information in Help Center and on the MacBook Pro Support website
at www.apple.com/support/macbookpro.
If you experience a problem working with your MacBook Pro, there’s usually a simple
and quick solution. Think about the conditions that led up to the problem. Making
a note of things you did before the problem occurred will help you narrow down
possible causes and find the answers you need. Things to note include:
 The applications you were using when the problem occurred. Problems that occur
only with a specific application might indicate that the application is not compatible
with the version of Mac OS X installed on your computer.
 Any new software that you installed, especially software that added items to the
System folder.
 Any new hardware that you installed, such as additional memory or a peripheral.
An Ounce of Prevention
If you have a problem with your computer or software, having kept up-to-date
Time Machine backups ensures that your data won’t be lost. If you make regular
Time Machine backups, you can restore your software and all your data to exactly
the way it was at the time of the backup. Even serious issues are of less concern
when you safeguard your information with Time Machine.
