Hi there, I've been spending the day installing several versions of Windows 7 on my Macbook. Initially, the plan was to put the 64-bit version on it, but there was some trouble with Bootcamp drivers with that one. Further more, I read somewhere that it's not supported, only 32-bit is. Is this true and if so, why? I was planning to use the Macbook as a render node, when not needed on other work and 64-bit Windows would be quite essential. Thanks!
