m Check the startup disk and program you were using when the problem

occurred. Make sure that all programs, desk accessories, and system

extensions you’re using are compatible with the system software.

m Sometimes incompatible system extensions or control panels can cause

system software problems. Restart while holding down the Shift key; this

temporarily turns off all system extensions. If your computer works

normally after you do this, remove all extensions from the Extensions

folder (inside the System Folder) and put them back into the Extensions

folder one at a time. Restart after you add each extension. This procedure

should identify any incompatible extensions.

You can also use the Extensions Manager control panel to turn off

individual extensions. For information on using this control panel to

manage system extensions, see the “Setting Options” topic of Macintosh

Guide, available in the Guide (h) menu.

m If the problem recurs, you may need to reinstall system software. See

“Installing or Reinstalling System Software” later in this chapter for

instructions.

A dialog box with a bomb appears.

Your system has a software problem.

m Write down what you were doing when the message appeared, and write

down the message’s text and its number, if there is one.

m Restart your Macintosh. (See “Start Over” in the section “When You Run

Into Trouble” earlier in this chapter for instructions.) Most software

problems are temporary, and restarting usually corrects the problem.

m Check the startup disk and application program you were using when the

dialog box appeared. Make sure that all programs, desk accessories, and

system extensions you’re using are compatible with the system software.

Reinstalling the system software may correct the problem.
