I am trying to get ioquake3 to run in El Capitan - currently 10.11.5.
I have placed the pak0.pk3 in the baseq3 folder of ioquake3.
Everytime I run the ioquake3-1.36 - which I assume is the latest - it starts, has a black screen for a second and then quits with a 'ioquake3 has unexpectedly quit' message.
Any ideas? Am I doing something wrong.
