(Presumably Apple will continue allowing future versions of macOS to run in virtualization on Mac hardware.) OS X 10.10 and Adobe Photoshop CS5 virtualized in VMWare Fusion 10.īut you’re free to virtualize Mac OS X 10.7 Lion, Mac OS X 10.8 Mountain Lion, Mac OS X 10.9 Mavericks, Mac OS X 10.10 Yosemite, Mac OS X 10.11 El Capitan, macOS 10.12 Sierra, and macOS 10.13 High Sierra.

Second, there are some specific versions of macOS that are allowed for virtualization: Mac OS X 10.5 Leopard and Mac OS X 10.6 Snow Leopard can only have their server versions virtualized, so if you need to dip back that far you’ll need to dig up a Mac OS X Server disc or buy an old one on the internet. First off, you can only emulate macOS on hardware running macOS. It’s not widely known, but VMWare Fusion and Parallels Desktop can run virtual versions of macOS, too. But what about those old Mac apps that are going to be obsolete soon? And what about those apps you abandoned when you upgraded to Mountain Lion or Mavericks or Yosemite or El Capitan? Running Windows apps can be really convenient if you rely on them. Since both macOS and Windows use Intel processors, this isn’t emulation (where the software is pretending to be computer’s processor itself), but it’s still virtualization, since Windows and its apps think they’re inside a Windows PC when they’re really inside an app running on a Mac. Parallels Desktop, both of which let you run Windows apps while you’re also running macOS.

If you’re a Mac user, you may know virtualization from apps like
