Apple has seen fit to remove the Java Preferences app from the Utilities folder

  • 0

Apple has seen fit to remove the Java Preferences app from the Utilities folder so there’s no longer any GUI way to go about increasing the allocated memory limit for Java.

I’m not really a commandline guy so I thought I’d ask here.

I have a few apps that need large memory allocations, I’m running 16GB of RAM on this machine so I’m not concerned about running other apps while these run, not to mention I don’t run these apps very often.

I’d like to increase my allowed memory limit to 6144m but I can’t see how to do it correctly.

This is the code I found but after running it and checking my Activity Monitor the app in question is still only accessing about 800m and it eventually uses up the heap and crashes.

export _JAVA_OPTIONS='-Xmx6144m'

Can someone please help me with this?

    From this article on the missing Java Preferences after the recent update it looks like you can download Java 1.7 and will then have access to Oracle’s Java Preferences under System Preferences.

    Note that your apps may or may not run under Java 1.7 – upgrading can always be risky.
