Increase the application preferred memory size
In classic Mac OS (but not Mac OS X), you may need to increase the amount of memory allocated to a program. This can sometimes fix problems when running the program or improve performance when you have more memory installed in the computer.
Mac OS 9 office systems at RIT, for example, typically had 32-128 MB of memory installed. However, many programs would not make use of all the available memory unless you modified their settings slightly. (Mac OS X automatically allocates memory for each application as needed.)
To increase the amount of memory alloted a program:
- Quit the application so that it is no longer running. (Generally, use File menu > Quit.)
Note: You cannot change the amount of memory assigned to a program while the program is running.
- Find the program's icon in the Finder.
- Click once on the program's icon to highlight it.
- Select File menu > Get Info.
- Choose "Memory" from the "Show" pop-up menu in the "Get Info" window.
- Type a higher number in the "Preferred Size" field.
Note: Start by doubling the "Preferred Size." If doubling this figure doesn't resolve your memory-related problem with the application, there may be other problems that simply changing the memory allocation won't solve.Note: Do not change the "Minimum Size" field. This sets how much memory the application will use at the minimum; increasing may actually create problems. The "Preferred Size" field provides the upper limit and is therefore safer to change.
- Close the "Get Info" window to save the changes.
- Re-launch the application. If you were having a memory-related problem, determine whether it persists.
