It's easy to become envious of Apple's recent MacBook Pro's, particularly since the launch of the retina range, which brought a crystal-clear screen resolution to OS X users. Snag is, there are still plenty of users who either do not want to use OS X or, more likely, are forced to use a Windows laptop for their work.
One solution is to use a virtual emulator, such as Parallels for VMware Fusion. A virtualisation tool enables to use Windows on top of of OS X, ideal for testing, running lightweight applications and for sharing files between the two operating systems. What a virtualised version of Windows doesn't do, is enable you to play the most demanding games or applications. For this, you need to run Windows in native mode.
Apple released Boot Camp for OS X users, designed to allow you to run Windows on your Mac, natively. With Boot Camp, you can install Windows and dual-boot, choosing to run either Windows or OS X, when you start your Mac. If you run Windows natively, you are using the full power of your Mac, with dedicated drivers. Ideal for running applications at full speed.
Boot Camp 5 is the brand new version with full support for running Windows 8 (or Windows 7) on your Mac. Note that this version won't support XP or Vista.
It's important to point out that Boot Camp 5 is part of Mac OS X. The download here is the Boot Camp 5 Support Software, which includes the latest drivers. You'll need to extract the downloaded file contents to a USB drive. Follow the install instructions for more information.
