How to Increase Application Memory on Mac

Click the arrow to the left of “Memory:” so that it is facing down in Mac OS X 10.2.x and later.

Select Memory from the pop-up menu in Mac OS X 10.0.x and 10.1.x.

Enter the amount of RAM you’d want to allocate to the application in the “Preferred size:” section. The “Minimum size:” parameter tells how much free RAM the application requires to run. 

The “Suggested size:” field is not editable.

Make sure the programme you want to increase the memory allocation for is closed. The application’s icon should be highlighted.
