How to increase the VM memory for IntelliJ IDEA on OSX

December 8th, 2009

To change the VM memory settings from the default value of 256 MB, you should modify Info.plist found in:

/Applications/IntelliJ IDEA 8.1.4.app/Contents/Info.plist

You have to change the VMOptions at the end of the file:

<key>VMOptions</key>
<string>-Xms64m -Xmx512m -XX:MaxPermSize=256m -Xbootclasspath/a:../lib/boot.jar -ea</string>
