I love Retroarch and use it on a Windows 7 PC at work perfectly fine.
At home I have a 2011 iMac i5 with 8GB ram running latest OSX (el capitan). I’ve downloaded multiple different versions of Retroarch incl;uding the Nightly builds but none work. All come up with some errors either that the DMG is damaged or else that it wont work with my OS.
My only alternative right now is to use the Windows XP version (I have XP installed via Parallels) but that sucks because PC Engine CD won’t work with sound.
Please help
