The final choice depends on the consumer’s needs, and in this case there are multiple factors to consider. If free solutions are required due to budget constraints, then Boot Camp is by far the best option. Still, either choice comes with compromises: Apple’s solution limits the guest operating system choice to only one platform and has other challenges such as having to find a way to share folders and the need to reboot the Mac every time platforms are switched.
Parallels Desktop, on the other hand, incorporates all the extra features of a virtual machine, meaning that it offers users the convenience of running multiple operating systems simultaneously including a wide variety of supported platforms, which is great for getting the job done. However, users need to consider a roughly 10% performance penalty, as its host must share the hardware resources with whichever guest OS is being operated.
