On El Capitan (osx) here with the following in ~/Library/Preferences/IntelliJIdea2016.2/idea.vmptions : 

-Xms1280m
-Xmx2000m
-XX:MaxPermSize=512m
-XX:ReservedCodeCacheSize=128m
-XX:+UseCompressedOops
-Dide.mac.file.chooser.native=false

However upon restarting Intellij we see the following setting: -Xmx768m . So IJ is ignoring the idea.vmptions file .. ? What is the proper procedure to update those VM settings?

Update I also tried changing the values in 

sudo vi /Applications/IntelliJ\ IDEA.app/Contents/bin/idea.vmoptions

That also had no effect: still the same -Xmx768m shows up under ps -ef | grep ntellij

Update The answer from @morfic inroduced a capability from Intelli to use Help | Edit custom VM options. However the values shown there are identical to the ones above (e.g. -Xmx2000m) and not respected.

  • Do you have any [IDEA_VM_OPTIONS environment variable defined](https://www.jetbrains.com/help/idea/2016.2/increasing-memory-heap.html)? As per [this answer](http://stackoverflow.com/questions/13578062/how-to-increase-ide-memory-limit-in-intellij-idea-on-mac/13581526#13581526) can also try using `Help` -> `Edit Custom VM Options` starting with IJ 15.0.4 – Morfic Aug 09 '16 at 07:04
  • @Morfic Please make this an answer and I can mark as 'helpful" – WestCoastProjects Aug 09 '16 at 13:05
  • I'm glad if I somehow helped, but if you found the answer yourself starting from a suggestion, I believe it would be better for everyone if you posted it and chose it as the correct one to keep things clearer, don't you agree? :-) – Morfic Aug 09 '16 at 13:09
  • Btw `However upon restarting Intellij we see the following setting: -Xmx768m` where are you seeing this? Are you sure it's the IJ VM and not something related, such as maven or other subprocess? – Morfic Aug 09 '16 at 13:17
  • @Morfic It is fair practice to award "helpful" to an answer that helps lead to a solution. – WestCoastProjects Aug 09 '16 at 13:37
  • I know and I agree, but so far I consider it to be just a simple comment since we did not get to the bottom of the problem yet. Also, did you see my second comment above regarding `However upon restarting Intellij we see the following setting: -Xmx768m`? – Morfic Aug 09 '16 at 13:47
