A dialog box with a bomb appears.
There is a software problem.
mWrite down what you were doing when the message appeared, and write down the text of the message.
mRestart your Macintosh. (See “Start Over by Restarting Your Computer” in the section “If You Have Trouble” earlier in this chapter.) Most software problems are temporary, and restarting usually corrects the problem.
mIf the problem recurs, 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 (as described in the next paragraph). Reinstalling the system software may correct the problem. See Chapter 7, “Reinstalling Your Computer’s Software.”
mSometimes 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, use the Extensions Manager control panel (in the Control Panels folder in the Apple [K] menu) to turn on extensions and control panels one at a time. Restart after you turn on each extension. This procedure should identify incompatible extensions and control panels. (If you just added new software to your computer, its system extension is the most probable cause of the problem.) For detailed instructions, see the information about managing system extensions in the “Customizing Your Computer” topic of Macintosh Guide, available in the Guide (h) menu.
If your computer performs better when a particular extension or control panel is turned off, contact the software’s manufacturer for information or an upgrade.
