Reporting very good results for the early 2008 17' MacBook Pro here. Specs: Early 2008 MacBook Pro 17' Mac OS X 10.6.8 Snow Leopard 2.5GHz Intel Core 2 Duo Processor 4 GB RAM NVIDIA GeForce 8600M GT 512 MB Graphics Card My system doesn't match the system requirements for the game at all, but it runs better than the crossover implementation. I was having the atmospheric transparency issues as well as right-click-drag for camera movement issues that most were reporting. I now have no problem with either. I can even get into the Black Lion Trading Post now! I've set the graphics settings to 'Best Performance' just because it makes my laptop run really hot (180 degrees Fahrenheit). The only problem that I've seen with it so far is that it doesn't recognize my mouse's scroll wheel in game interface, so I can't scroll in inventory, etc. If that's the only problem I'm seeing, then I'm a happy camper. I wasn't going to even try it, but some others reported that the beta worked on Snow Leopard, regardless of the specs on the site saying 'OS X 10.7 or better'. Glad I gave it a shot.
