Izhido has spent several months working on a port of Quake for Apple's OSX. He has three targets for his project: OSX 10.11, tvOS 9.1, and iOS 9.3 for iPhone. The iPhone one is specially made for doing 3D VR, with something like Google Cardboard.
There's no execuatables but you can obtain and compile the code yourself. The code is on his github page.
Thanks to Func_Msgboard for the post.
