So I just got 2 copies of Snow Leopard. Installed one on my imac and it's perfect. The thing is I saw a thread and many of you were complaining that in the macbooks/macbook pros your computer was running much hotter. idling at 10ºc more. I really want to install SL on my mbp but not if it will result in higher temperature... it already idles at 45-50ºC. Just wondering if Apple will ever fix this issue or I'll just have to live with it.
