How to Increase the Memory for a Macintosh Application

Single-click the icon for the application to which you want to allocate more memory. Be sure to exit the application first.
From the File menu choose Get Info, or press the keys Command-I.
In OS 8.5 and later versions, select Memory from the Show menu in the box that appears.
Type a new value into the Preferred Size box, perhaps 1.5 or 2 times the suggested size shown. You can decrease the memory in the same way.
Click the close box. Your change will take effect the next time you launch the application.
