Okay, serious problem.
(don't flame because I'm on a mac pls)
So the computer that I'm using is completely qualified to play TF2, but the steam client for mac is shaky at best. Every time it tries to validate the cache files, it slowly loads up to 100%, then just stops. Does absolutely nothing.
I've realized that the only way I can play TF2 is by deleting and re-downloading the entire game every time I want to play, which takes forever and wrecks our bandwidth.
The forget do I do?
