Can I run RealFlight on a Macintosh Computer?
RealFlight is compatible only with Microsoft Windows and cannot be used with Mac OS/OSX operating systems. But if you can run Windows on your Macintosh computer, you should also be able to run RealFlight.
Apple now offers a program called "Boot Camp" that does allow Macintosh users to dual-boot Windows with Mac OS/OSX. For help installing Windows onto your Mac using Boot Camp, contact Apple Support.
