Creating a test environment for Mac software

My company develops commercial Mac software. Our flagship product runs on OS X 10.6.8+. We want to improve our software quality with better and more comprehensive testing.

What hardware and OS’s should we supply our tester with? My thought so far is either a Mac Mini or an iMac with an SSD, lots of RAM, and either Parallels or VMWare so that he can run OS X 10.6.8, OS X 10.7, OS X 10.8, OS X 10.9, and OS X 10.10 in virtual machines.

Is this feasible? Recommended? I’d love to hear your feedback.

(Cross posted here:

I support back to Mac OS X 10.5, but my oldest working Mac has 10.8. So I pay the guys at to test on versions of Mac OS X I don’t have here.

I’ve never quite understood the licensing situation about running Mac OS X inside a VM.
