As someone who was a former mac only gamer, yeah, Apple's update that killed 32 bit games pretty much destroyed a bunch of steam games to the point of no return and it makes the platform even more difficult for developers. Online-focused games having to update in such an environment is far too risky considering how few of sales actually come from mac users. It's pretty depressing, to be quite honest. I'm glad I got a PC when I did, but for those few who were mac only owners like me, this must be beyond annoying to deal with, since it seems every week there's a new game that loses mac support or cancels a release on the platform
