Apple 7100 manual If your computer’s performance decreases

If your computer’s performance decreases

If you notice a decrease in your computer’s speed and general 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 Power Macintosh computers.

mTo 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.

mUse the Extensions Manager control panel to turn off a system extension or set of extensions. For detailed instructions, see the “Setting Options” topic of Macintosh Guide, available in the Guide (h) menu. If the computer performs better when an extension is turned off, contact the extension’s manufacturer for information or an upgrade.

mDrag 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 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” later in this chapter to reinstall system software on your startup hard disk.
