After you open an image on a Photo CD, your system is “frozen” and does not respond
to any input, or you have a “bomb” message on your screen.
m Restart your Macintosh. (If you need help restarting your computer, see
“Start Over by Restarting Your Computer” in the section “If You Have
Trouble” at the beginning of this chapter.) The program you are using may
not be designed to work with large (high-resolution) image files. You can
open the image with another program or you can assign more memory to
the program. See the “Memory” topic of Macintosh Guide, available in the
Guide (h) menu, for more information on managing memory.
If your computer’s performance decreases
If you notice a decrease in your computer’s speed and general performance
after you install special software (a control panel, system extension, or custom
utility), it may be because the software is not compatible with Macintosh
computers built with the PowerPC microprocessor.
m To fi nd out if a system extension or control panel is the problem, hold
down the Shift key while you restart the computer. This temporarily turns
off control panels and extensions. If the computer performs better without
these software items, one of them is likely to be the problem. (If you just
added new software, its system extension, control panel, or custom utility is
the most probable cause of the problem.)
To fi nd out which software is the problem, use the Extensions Manager
control panel (in the Control Panels folder in the Apple [K] menu) to turn
off a system extension or set of extensions. (If you just added new software
to your computer, its system extension is the most probable cause of the
problem.) For detailed instructions, see the information about managing
system extensions in the “Customizing Your Computer” 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.
