I have set up Windows 8 64 bit on a MacBook Air using VMWare Fusion 5 Professional.

The MacBook Air is from Oct 2012 and has an Intel Core i7 2GHz and 8 GB 1600 Mhz DDR3 RAM.

I have Windows 8 running with no other programs open but it constantly uses around 50% CPU on the Mac and the fan is running at full tilt. The VM is set up with 4GB of RAM and 2 CPU's with 2 Cores.

Is there a way to make it not overheat the Mac? Is anyone running a Windows 8 64 bit VM on a MacBook Pro or other Mac that can give me an idea if that works better?

Thanks.

Are VMWare tools installed and running in the VM? –  jaume Mar 5 '13 at 13:09
    
Yes. The VMware tools are installed in the Windows 8 VM. –  Adam Mendoza Mar 7 '13 at 5:20

Check the support forums on the Apple site. I have had the same problem with 2 MacBook Airs and a new MacBook Pro Retina. The issue is due to excessive disk writes the OSx is pushing to create the Hibernation files. The solution (turn off the Hibernation via the Terminal app) is NOT supported by Apple but it does help quit a bit. Until Apple fixes this in their OS, this is the only solution I have found. I too am running Windows 8 64Bit in Fusion. (https://discussions.apple.com/thread/4029639?start=30&tstart=0) go to page 6 and 7 of the post. Good Luck

Welcome to the site. The goal on AskDifference is to have answers stand on their own. So instead of having everybody search through the Apple Forum can you please summarize the essentials directly into your answer? –  patrix Apr 1 '13 at 8:44
