The software itself is part of macOS, so installing Windows on Macs using the legacy HFS+ file system is smoother than those using the Apple File System and Time Machine or FileVault. In other words, Boot Camp allows you to run Windows without the compromise of using just one processor or only a limited amount of RAM, the sorts of restrictions that would be imposed by virtual machines as they balance the various resources to optimize the running of two operating systems side by side. What sets the Windows experience apart from any virtualization software is that users can take full advantage of their hardware in every possible way, the Retina display included, so long as you agree to allocate at least 40GB of space on the startup disk for this operating system. Apple's multi-boot utility – which has been included with the Mac operating system since OS X 10.5 Leopard – guides users through installing Windows on Intel-based Macs, and it's actually pretty easy to get started if all the necessary components are in place. There is another way to take the Windows experience to the next level: run it on a Mac using Boot Camp. Requires at least 40GB of allocated space.
