One of the selling points of a Mac these days is the ability to run Windows software on it, via virtualization or Apple’s own Boot Camp. Running Windows lets you play PC games that haven’t been ported to the Mac, or stay completely compatible with your documents from a PC-centric workplace.
Virtualization software like Parallels or VMWare Fusion (two of the best apps to run Windows software on your Mac without partitioning your hard drive for Boot Camp) isn’t free, though these applications do allow you to try before you buy. Windows 8.1, the current version of Microsoft’s operating system, will run you about $120 for a plain-jane version.
You can run the next-gen OS from Microsoft (Windows 10) on your Mac using virtualization for free, however. We took a quick run at doing just that, as originally sussed out by the fantastic folks over at iMore.
