The immortal IntellijIDEA on Mac

Using IntellijIDEA 12 on Mac you can try for 30 days free. However it doesn’t have to live that short. After it dies (expires), don’t uninstall, instead you can reset it through these easy steps:
delete:
~/Library/Application Support/IntellijIdea12
~/Library/Logs/IntellijIdea12
~/Library/Caches/IntellijIdea12
~/Library/Preferences/IntellijIdea12

That’s it, relaunch and it starts young again.
