m Use the Memory control panel to reduce the size of the disk cache, remove or reduce the size of

your RAM disk, or turn on virtual memory. For more information, see Mac OS Guide, available in the
Guide (h) menu.

Note:  If you have both virtual memory and a RAM disk turned on in the Memory control panel,
don’t set both of them at or near their maximum values. Doing so can result in unpredictable or
reduced performance by your computer. (RAM disk uses random-access memory, or RAM, as if it
were a hard disk.)

m Turn off system extensions that you don’t need. For more information, see the topic on system

extensions in Mac OS Guide, available in the Guide (h) menu.

m If you have installed system software additions from the Apple Extras folder such as QuickTime

Conferencing or PlainTalk, you may want to remove them if you are not using them. (This software
can decrease the amount of RAM available for use by application programs.) To remove a system
software addition, locate and run the Installer for the software, and use its Custom Remove option
to remove it.

m If you frequently want to open more applications than memory allows, you may want to install more

random-access memory (RAM). See Chapter 10, “Installing Expansion Cards and Memory.”

The computer “freezes.” (Nothing moves on the screen.) 

m Your computer may be trying to complete a task, but it’s taking so long that it seems that the screen

is frozen. If you need to do something else instead, try simultaneously pressing the Command (x)
key and the period key (.) to cancel the task the computer is working on.

m There may be a temporary software problem that can be fixed by restarting your computer. Follow

the instructions in “Step 2: Restart Your Computer” in Chapter 11, “Start Here If Trouble Occurs.”
