Your system has a software problem.

Restart your Macintosh. For instructions, see “Start Over” in the section
“If You Have Trouble” earlier in this chapter.

Check the startup disk and application 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.

If the problem recurs, try restarting the computer with system extensions
turned off. (To turn system extension off, hold down the Shift key while
restarting the computer.) If that doesn’t work, you may need to reinstall
system software. See “Installing or Reinstalling System Software” later in
this chapter for instructions.

If none of these procedures solves the problem, consult the service and
support information that came with your computer for instructions on how
to contact an Apple-authorized service provider or Apple for assistance.

You can’t open a document, or you see a message that an application program can’t

be found.

Some documents can be opened by more than one application program.
Try starting a program that you think might be able to open the document,
then choose Open from the program’s File menu to try to open the
document.

Purchase and install the correct software to use the document, or find out
if the creator of the document can convert it to a form that one of your
programs can use.

Don’t try to open the files in your System Folder. Most of the files in your
System Folder are used by your computer for internal purposes and are not
intended to be opened.

Rebuild your desktop by holding down the Shift key while starting up your
computer. Keep holding down the Shift key until you see a message that
extensions are turned off; then hold down the Option and x keys. Keep
holding down the Option and x keys until you see a message asking
whether you want to rebuild the desktop. Click OK.

If the document is from a DOS computer, use the PC Exchange control
panel to specify which Macintosh program will open the document. For
information about working with DOS documents on your Macintosh,
see the information about DOS in Macintosh Guide, available in the
Guide (h) menu.
