By taking advantage of virtualisation software, it is possible to install and experiment with other operating systems.
It might be that you own a Mac and have always wondered if Windows is really as bad as some people make out. The answer is, generally, yes but Windows 10 looks interesting so install that one.
It might be that you have software that only works on a particular operating system with no version being available for OS X. Again, this is where virtualisation can help.
Virtualisation software allows you to install other versions of OS X, Windows, Linux—such as the popular Ubuntu distro—and more besides.
In this tutorial, I’ll show how you can test drive El Capitan without overwriting the hard drive in the Mac. Ideal if you just want to see if Apple’s new iteration of OS X is right for you.
