If you notice a decrease in your computer’s performance after you
add special software (a control panel, system extension, or custom
utility), it may be because your special software does not work well
with the PowerPC microprocessor.
• To find out if your special software is the problem, hold
down the Shift key while you restart the computer. This
temporarily turns off certain kinds of software. If the
computer performs better without this software, the
software is likely to be the problem.
• Use the Extensions Manager control panel to turn off a
system extension or set of extensions. For detailed
instructions, see the “Customizing Your Computer” topic
area of Mac OS Guide, available in the Guide (
T
) menu. If
the computer performs better when an extension is turned
off, contact the extension’s manufacturer for information or
an upgrade.
• Drag special software items out of the System Folder or
remove them permanently. (The special software may be in
the Control Panels or Extensions folder inside the System
Folder.) If the computer performs better when the software is
removed, contact the software’s manufacturer for
information or an upgrade.
Hint: If you have more than one special software item, drag
all the special items out of the Control Panels and Extensions
folders. Then return them to the folders (one at a time),
restarting and checking your computer’s performance each
time until you identify the one that is causing problems.
If you still do not notice an improvement, follow the instructions in
Installing or reinstalling system software on page 6-48 to reinstall
system software on your startup hard disk.
