RubyMine won't start under Yosemite, no loading screen, no error message.
This seems to be caused by the default JVM that comes with Yosemite
EDIT This also seems to affect WebStorm

Open this file
Check the version of Java, most likely 1.8, by using java -version, you should see something like:
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
Open and edit
/Applications/RubyMine.app/Contents/Info.plist
Or for WebStorm
/Applications/WebStorm.app/Contents/Info.plist
Update the following key
<key>JVMVersion</key>
<string>1.7*</string>
to
<key>JVMVersion</key>
<string>1.8*</string>
RubyMine should now be good to go
Feedback on this solution
JetBrains do not recommend this solution as it will break autoupdating with patches. That tradeoff was acceptable for me as I just wanted to get going quickly and avoid installing Java 1.6.

You shouldn't edit your plist file since it will prevent Rubymine from autoupdating. This is direct from their support pages:
Modifying Info.plist will break the application digital signature and prevent the patch updates. We do not recommend modifying Info.plist file to run under JDK 1.7 or 1.8.

The correct answer is to install Apple JDK 1.6
回答3:
JDK 1.6 is required to run and may be missing on your system. Please install Apple JDK 1.6. There should be a window with the suggestion to install Java when you start the product for the first time, but it could be hidden by other application windows.
Apple JDK 1.6 download: http://support.apple.com/kb/DL1572.
I have tried to down load the JDK 1.6, it works in my Mac.

Just install java for OS X, and it'll solve the issue.
Up till OS X El Capitan(10.11), this link solves. Or you can just google "java for osx", most probably first link will show you the right answer.
