I just bought an older iMac (Intel Core 2 Duo) running the last possible OSX version 10.8. Only OpenEmu v1.04 or lower is working on this machine, all newer versions need at least OSX 10.11.

It looks like v1.04 (and all other lower versions) is starting/running well, that means I can click through the starting sequence and enter the main window. It is also possible to load any bios and import/launch roms. BUT it is not possible to start them: I tried different games on different platforms, but the result is always the same: Black screen/window, nothing happens, not even any error message is coming up.

Anybody who has an idea what's wrong or what to do to get OpenEmu v1.04 back to work?
