General tips
If your Macintosh or a component is not working properly but its problem is
not described in this chapter, you can try some general measures that may
solve the problem.
Start over
Often you can eliminate a problem simply by starting over.
- If possible, save any open documents in which you have made new changes
before restarting the Macintosh. (If your system is frozen or you have a bomb
message on the screen, saving will not be possible.)
- Choose Restart from the Special menu, if possible, or switch the Macintosh
off and then on again.
- If your problem is with a peripheral device, such as a printer or an
external hard disk, switch it off and then on again.
Make certain that all parts of your system software are from the same version
These practices help keep your system software in good working order:
- When you install a new version of system software, be sure to copy it onto
all the startup disks you use, to avoid inadvertently working with two
different system versions later.
- If the System Folder becomes damaged on one of your startup disks, either
reinstall the software on that disk or copy the System Folder from a good
disk onto the disk with the damaged folder.
- When you install a new version of system software, verify that the new
versions of drivers for the printer and other types of devices you use are in
the System Folder of your startup disks.
Make certain that your programs are in good working order
Here are tips for keeping your application programs working effectively:
- Make a backup copy of your application programs for safekeeping in case
your working copy is ever damaged.
- If you have problems with a program, make another working copy of that
program from the original program disk.
- If making a new copy of the program does not correct the problems with it,
check with the program's publisher to make sure that the version of the
program you have is compatible with the version of Macintosh system software
you are using. (You can often upgrade to a newer version of the program for a
modest fee.)
- If you use a hard disk, be sure to keep only one System Folder and only one
version of each application program on your disk.
