Problem, Meet Solution
Occasionally you may 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 Mac Help and on the MacBook Pro Support website at
www.apple.com/support/macbookpro.
When you experience a problem working with your MacBook Pro, there is 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 the Mac OS 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.
