Classic applications in Mac OS X
When running Mac OS X, you don't need to manually set anapplication's memory size for native applications. Mac OS Xadjusts the amount of memory as the application requires more or lessspace. However, you do need to set an application's memory size ifyou are running an application in Mac OS X's Classicenvironment. To do this, follow these directions:
Mac Os Mojave
- Determine how much memory is available and accessible to your computer. This will give you an idea how much extra memory you can allocate to the application. From the Apple menu, select About This Mac.
- Make sure the application whose memory allocation you want toincrease is closed. Highlight the application's icon.
- From the File menu, select Get Info or ShowInfo. The application's information window should open.
- In the information window:
- In Mac OS X 10.2.x and later, click the arrow to the left of'Memory:' so that it is facing down.
- In Mac OS X 10.0.x and 10.1.x, from the pop-up menu, selectMemory.
- In the 'Preferred size:' field, enter the amount of memory you'dlike to allocate to the application. The 'Minimum size:' fieldindicates the amount of free RAM needed to permit theapplication to run. You cannot change the 'Suggested size:' field.

To allocate more memory to an application in versions of MacOS prior to OS X, follow these steps:
- Determine how much memory is available and accessible to yourcomputer. This will give you an idea how much extra memory you canallocate to the application. From the Apple menu, select AboutThis Computer (for Mac OS 7.0 to 7.5.5, select About ThisMacintosh; for System 6, select About theFinder...).
- Make sure the application whose memory allocation you want toincrease is closed. Highlight the application's icon.
- From the File menu, select Get Info, thenMemory. (In versions before Mac OS 8.5, you only need toselect Get Info.) The application's information windowshould open.
- Increase the application's memory allocation. The method differsslightly between older and newer versions of the operating system:
- In Mac OS 7.5 and later, in the information window you will see anarea labeled 'Memory Requirements'. In the 'Preferred size:' field,enter the amount of memory you'd like to allocate to the application.You cannot change the 'Suggested size:' field. The 'Minimum size:'field indicates the amount of free RAM needed to permit theapplication to run. If the 'Preferred size:' amount is unavailable, aslong as your computer has enough RAM to satisfy the minimumrequirement to run, the application will be available.
- In Mac OS 7.1 and earlier, near the bottom of the informationwindow you will see an area labeled 'Memory'. In the 'Current size:'field, enter the amount of memory you'd like to allocate to theapplication. You cannot change the 'Suggested size:' field. Bear inmind that you will always need enough free RAM to cover the newamount, or the application will not run.
