To be fair, there was a known Mac glitch last year regarding licenses. An easy workaround existed and was posted: Unlicense the game when patching.
Other than that, it's very Mac-compatible and is a solid game. I was trying to avoid reading up on OOTP 11 only because I've barely scratched the surface in last year's release (a testament to the game's depth). As soon as I read about revamped draft, I knew I needed this year's game.
Oh, and regarding "advanced stats like OPS+ and ERA+" . . .
For those interested in something a little more advanced, the game will also include wOBA, FIP and Zone Rating. Here's hoping for UZR too!
