Mac OS X Lion compatibility


anyone upgraded Mac OS X to Lion? Is IDEA Lion compatible?



It seems to be compatible but I haven't done more then some editing and unit testing in it yet.

Be aware that when you install Lion it wipes out your existing Java installation. If, like me, you're only doing Java 6 work, this is no big deal.

After the Lion install, when you go to run IntelliJ, Lion will inform you that you need Java and will ask if you want Java installed. It will automatically take care of downloading and installing Java, and when it's done, IntelliJ will start automatically. You'll have some indexing since the JDK looks like it's new to IntelliJ.

If you want to keep your older Java versions, you'll need to tar up the JDKs before installing Lion. I haven't tried it, but reports say it works ok to put them back after the Lion install.


Hi Charles,

thank you for your reply. Does Lion installs a JDK 1.6 or just a JRE?


I upgraded to Lion, and I'm having issues with IntelliJ.  It seems to get stuck trying to "update indices"...and then the OS tells me the Application is not responding, and I can do nothing at that point with the app than to Force Quit it.

doing a java -version gets me this

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)


Have you tried to explicitly invalidate caches via "File" > "Invalidate Caches..."?


aaah, good one...I invalidated the caches and it worked...thanks...


I have not done any exhaustive testing or coding but trying an app I've been working with is running fine on Tomcat 6.x with JRebel 4.x.


JDK, build 1.6.0_26-b03-383-11A511.


We are using the fsNotifier (file watcher) in our applications and it broke
on OS X 10.7.



Hi Tom,

it was fixed today.


I found an issue with Lion. Hide doesn't work right if you have floating tool windows. Take your project explorer, for instance, and put it in float mode, and then hit Command-H to hide IntelliJ. The main editor window will be hidden, but all the floating windows will remain.
