I run it on Parallels. Works OK. Mine is a 3 year old Mac Mini and with the recent Parallels upgrade to V7 I get a smokin 32fps. Haha. It's good enough. If you have a new, or newer, Mac, V5.5 runs using Parallels.
Yeah, but you need parallels or bootcamp and then you need a copy of windoz... money might be better spent just buying a native flight sim until RF releases a mac version... I would not hold my breath for that.
