It was just month ago, I wrote, if you were want to install Windows 8 on your Mac, the best way is to run it in a virtual machine rather than simply boot natively via Boot Camp. Let’s take a crack at it see how it stack against VMware Fusion when running Windows 8. Parallels released their new version Parallels Desktop 8 for Mac, that supports the latest Windows 8. In fact there are still more people use Parallels to run virtualized Windows on their Mac than VMware’s Fusion. Parallels is the one of the biggest competitor to VMware in Mac OS X.
