I need to run PowerPC-only programs roughly weekly. They're on a CD rather than the HD, so they escaped my pre-flight upgrade checks. As Rosetta was killed in the last upgrade it's problematic to run those programs in OS X Lion.
My options are as follows:
Downgrade to Snow Leopard;
Set up Snow Leopard on a bootcamped partiton;
Virtualise Snow Leopard under some kind of VM (VirtualBox, Parallels or Fusion).
I don't particularly want to do 1 or 2 unless I have to. I still want the benefit of Lion if I can — and rebooting to do a small printing job seems excessive, so it seems virtualisation is the best option.
Are there any other alternative methods I've missed? Is here a better product for running one Apple OS under another (simplest – I'm willing to pay if necessary)?
