I use Mac OS X 10.8.2, and use JDK 7. Now I downloaded the latest version of IDEA IntelliJ, 11. But it doesn\'t seem to start without JDK 6. Is there any workaround?
Others have suggested very good solutions but you have to do it manually vi editor etc. Instead you can run this command via your Mac Terminal and you will be good to go :
find /Applications/IntelliJ*/*Contents/*Info.plist -exec sed -i -e 's/string>1.6/string>1.7/' {} \;

Few optional tips:
To verify that the change took place run this:
grep "string>1.7" /Applications/IntelliJ*/*Contents/*Info.plist
