Is there any simple way to run rosetta under Yosemite?
If not, am I correct that Snow Leopard Server will run on Parallels (and it seems this is the 'legit' way, I'd like to be 100% legal), and that would solve my goal of hanging on to some PPC apps without the constant need to reboot to other drives or use multiple machines?
I'm running a mid-2010 Mac Pro, and need higher than Snow Leopard to run the new TurboTax, but wanting to hold on to an investment of $$ in PPC-only apps.
Update – I bought two Apricorn PCI cards to install SSDs without taking up HD space. One SSD boot Snow Leo, the other, Yosemite. At this point, the Snow Leo OS is the one I use most often, booting into Yosemite when I need the newer software. The SSDs offer such a fast boot that starting up/ rebooting is pretty fast, not too much trouble.

There is no way at all to run Rosetta in Yosemite. Rosetta was included in Mac OS X 10.4.4–10.6.8 (Intel) only.
The Apple license agreement doesn't allow customers to run a Snow Leopard client in a virtual environment.
So the only legal way to use PPC apps with Yosemite is indeed Snow Leopard Server (Apple part number is MC588Z/A internal link (It only works in their store)) in Parallels (10.0 recommended) or VMware Fusion (at least 6.0.5, 7.0 recommended).
