Sounds like you may be using the less expensive Mac Mini with the integrated Intel 3000 graphics, which is significantly weaker than the recommended graphics card for Macs in CoH: https://support.cityofheroes.com/app...KlN6OW1PKms%3D
There's no real 'fix' for this, short of getting a different Mac.
If you don't know what version of Mac Mini you're using, you should be able to get information under the Apple menu.

firstly, sorry if this has been posted before, but i can't seem to find a related thread.
i'm using the 2011 mac mini, upgraded to 8GB memory (everything else is stock). i'm fully up-to-date OS-wise.
i've only play CoH in this mac twice, and twice now, the same thing has happened. basically, after a while, i start seeing non-textured geometry (mostly buildings) and they're basically pure white...then 2 seconds later, the game freezes. i'm new to macs, and so i don't know how to return to the desktop, so i pretty much have to restart.
i have an older i3 laptop that doesn't have this problem. i really want to use the Mac because when it does work, it seems to have better performance.
