Extensions, Control Panels, and Utilities
If you notice a problem occurring after you add special software—a
control panel, system extension, or custom utility—that software may
simply not work well with Power Macintosh computers.
To find out if this is the problem, temporarily turn off the software . If
the computer performs better with these items turned off, the software
is likely to be the problem. Follow these steps:
1.
Hold down the Shift key while you restart the com-
puter.
This temporarily turns off your extensions, as well as certain con-
trol panels and utilities.
2.
Work with a document to see if you notice an improve-
ment in your system’s performance.
3.
If performance improves, then drag the special items
out of th e Control Panels and Extensions folders,
located inside your System Folder.
4.
Return them one at a time, restarting and checking
your computer’s performance each time until you iden-
tify which ones are causing the problems.
5.
Remove the offending items from your System Folder.
You also can use the Extensions Manager control panel to turn a sys-
tem extension or set of extensions off and on. For detailed instruc-
tions, see the “Setting Options” topic in the Macintosh Guide.
If your computer performs better with an extension turned off, contact
the extension’s manufacturer for information or an upgrade.
