I'm using Studio 5 (not 6) on OS X. The file is located in the following path: /Applications/Jaspersoft Studio 5.6.0.final/Jaspersoft Studio.app/Contents/MacOS/Jaspersoft Studio.ini Be sure to make a backup copy of the file, then change -Xms and -Xmx lines to the following (assuming you have enough RAM on-board): -Xms1024m -Xmx40964m Restart Studio and you should hopefully have enough resources allocated to the JVM.
