If you are in a mindset that you cannot really explore the use of Vista on your Mac then you might need to rethink. There are Macs that can run 64bit Vista. The only thing that must be taken into consideration is whether you want everything to be run on the Apple Solutions or go for something else that ensures you more flexibility. The later way is easier with virtualization technology. This can be obtained using many third party providers. A technical note recently mentioned by the Apple lists the MAC’s that can run Vista. It says that the 2008 flavors of MAC that run on Intel processors and motherboards can now run Vista 64-bit version. The Mac Pro workstation, the 17-inch MacBook Pro and 15-inch MacBook Pro notebooks can run Vista.
It is totally a different story when we look outside the Boot Camp. On the other hand VMWare Fusion already supports the 64 bit versions of Vista as well as its predecessor Microsoft Windows XP professional and in fact many other Linux and Unix operating systems. The Mac needs to have Intel Core 2 Duo or a Xeon processor for Vista and others to work on it. This kind of processor drastically extends the usage of different kinds of OS flavors and types. They can have them run on Macs, iMacs and even the lighter version MacBook Air. Mac Mini is also supposed to have support for the same.
VMWare Fusion stands first when it comes to the 64-bit kind of support and this proves it to be different from those of parallel desktop which basically has support only for Operating systems of 32-bit alone. The one from Mac for parallel OS can run both 32 and 64 bit OS and it is priced at around $1200.
