I just about fell out of my chair when I read this post from Mozilla’s Asa Dotzler:
I’m sitting here with my Leopard preview install DVD and I can’t work up the courage to just blow away Tiger on my only Mac (my primary machine — a MBP.) Heck, I don’t even know if Firefox runs on Leopard.
My first thought was to install Leopard under Parallels on my MBP — just the way I do Vista under VMWare on my Thinkpad. Apparently that’s not possible since Leopard will only install on genuine Mac hardware and Parallels is virtual hardware, even if it’s running on a Mac.
Emphasis added.
That sucks. Especially as Apple are now encouraging users to try Parallels as an alternative to Boot Camp (see this page). But then I suppose Apple doesn’t expect you to want to run multiple copies of OS X side-by-side and test releases of OS X aren’t publicly available, like with Vista.
The license for OS X is pretty clear about the fact that you must run it only on genuine Apple hardware, but that’s exactly what you’re doing, albeit with a virtualisation layer.
Maybe Apple needs to work with Parallels to allow their software to run OS X in virtualised mode. Doesn’t make the situation any less silly though.
