I’ve already written several articles on virtual machines because they are a great way to keep you safe from viruses and increase your privacy. The second best choice in my opinion if you need Windows installed locally on the machine is to use a virtual machine. Overall, if you need a full copy of Windows and want to fully utilize the specs of your Mac, I suggest using Boot Camp.
You’ll also need to have about 50 to 100 GB of free space available on your Mac in order to install Windows. With a full copy of Windows, you can install any and all programs without limitation. This means it’ll be faster than any other method mentioned below. The advantages of using Boot Camp are two-fold: you get an entire copy of Windows installed and it is running directly on the Mac hardware.
