I need a time waster.
>Compatible with Macs
Pick one. :P
^ Pretty much that, although the Sims 3 is compatible with Macs. That's the only game I know of though, there might be like one more but other than that, we're out of luck :/
I thought I was your time-waster. :c
Minecraft and the Humble Indie Bundle are both on Mac. Money is a factor though, but no so much with the second one.
