Kenney Studio 0.51 won't start on OS X El Capitan. In the console I see this error:
16-07-26 20:01:26,332 com.apple.xpc.launchd[1]: (com.kenney.studio.228192[14584]) Service exited with abnormal code: 4
I know version 0.51 is deprecated, but I'm reporting this problem just in case it's an easy fix. Otherwise, forget it! ;)
