Okay. I am about to go to the Apple store to purchase Leapord, in order to use Windows Vista (So i could use SteamPowered to play such games as HalfLife 2). Now I have heard of some consumers saying Leapord has crashed their systems or programs much more frequently. I have an Intel iMac with 500 Gigabytes and 2 Gigs of Ram (I think). Is there any alternative to buying Leapord just for the use of Bootcamp to play games, and will Leapord run smoothly on my system? PS. I apologize for any typos. I am in a rush. And, please respond ASAP if you have an answer.
