I know its an old game, but still lots of fun when I had it on El Captian, but now it crashes at launch. Anyone know of a patch or is this game pretty much dead on HS?
Works fine for me! Dirt 2 V1.0 running on late 2012 27" iMac with High Sierra 10.13.6 and GTX680MX GPU.
At launch, you get the 'not compatible' warning for not being 64-bit, which will be enforced in a future MacOS. Just click OK on that and proceed (for now).
