5 Troubleshooting
Occasionally you may have problems while working
with your iMac. This chapter gives you some
solutions to try when you have a problem.
This chapter provides solutions to problems that prevent you from working with your
iMac, such as a system freeze or an iMac that won’t start up. You can find more
troubleshooting information in Mac Help (see page 29) and on the Apple Service and
Support website at www.apple.com/support.
If you experience a problem with your iMac, there is usually a simple and quick
solution. If you encounter a problem, try to make a note of what you did before the
problem occurred. This will help you narrow down the possible causes of the problem
and then 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 may indicate that the application isn’t compatible
with the version of the Mac OS installed on your iMac.
