Fixing IntelliJ IDEA after install of Yosemite (IntelliJ IDEA quit unexpectedly)

If your IDEA fails to open after you've switched to OSX 10.10, with error like this

And error message in report says something like

Dyld Error Message:
  Symbol not found: _CGContextSetAllowsAcceleration
  Referenced from: /Library/Java/JavaVirtualMachines/1.6.0_41-b02-445.jdk/Contents/Libraries/libawt.jnilib
  Expected in: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices

Open your /Applications/{YOUR_IDEA}/Contents/Info.plist file and point to a newer java by changing

<key>JVMVersion</key>
<string>1.6*</string>

to

<key>JVMVersion</key>
<string>1.7+</string>

If you have blurry UI on your retina device, update to the latest 1.7 version or get a 1.8 and set above as 1.8+
