Is it possible to install Windows on a Mac machine and Mac OS on a normal PC?

• A system with a 64bit Intel processor is required as a general rule. You'll also need a second hard drive to install macOS on, one that has never been used to run Windows. You should have at least 50GB of free space on your hard drive if you wish to run anything other than the basic OS.
• Boot Camp Assistant assists you in creating a Windows partition on your Mac's hard drive and then installing Windows software.
• You can start your Mac in either Windows or macOS after installing Windows and the Boot Camp drivers.
