Parallels costs more (since VirtualBox is free and Parallels is not), but there are hundreds of little design touches that help make running Windows within macOS as painless as possible, and that make setting everything up quick and easy. There are other virtual machine options available to Mac users, including the open source VirtualBox, but Parallels is different in that it’s designed exclusively with Mac users in mind. Virtual machines are complicated, but Parallels makes it reasonably simple to set one up and use it. You can even combine the two desktops, if you want, and run Windows software right on your Mac desktop from your Mac’s dock.
This allows you to quickly switch between the Mac and Windows desktops. Parallels runs Windows within macOS, using what’s called a Virtual Machine. Sure, you could set up your Mac to run Windows with Boot Camp, but that means restarting your computer every time you need to use Windows.
