I just upgraded my RubyMine to v8.0.0 with the custom bundled JDK. After installing it I tried to open the app from it's icon and nothing happened. I mean it showed me the dialog box if I trust the app (this happens whenever you want to open a new installed app for the first time), but afterwards nothing showed up.
I looked through the app processes, and couldn't find the RubyMine app. I also tried the solution from this question:
RubyMine fails to start on Yosemite
No success.
After I ran chmod +x /Applications/RubyMine.app/Contents/MacOS/rubymine, I tried again from the app icon, but it still doesn't seem to work.
I updated my java version to java version "1.8.0_65" and still no luck.
It works when I run /Applications/RubyMine.app/Contents/MacOS/rubymine from the command line.
Just to be clear, before upgrading to v8.0 this problem didn't occur.
I run OS X Yosemite.
Any ideas what can cause this issue?
[UPDATE] I ended up downgrading to v7.1.4 until this gets solved.
Found the problem. Looks like I had to run the app in 64-bit mode.
Right click app icon -> Get Info -> "Open in 32-bit mode" must be unchecked.
