Rick--As far as i know, Mountain Lion, OS 10.8.5, don't support Rosetta or Rosetta stone. If you find a way to use power pc programs on an OS 10.8 computer, PLEASE let me know. I just got a new MacBook Pro a couple of months ago with Mountain Lion, and there seems to be no way of using the power pc programs with this operating system. I knew this when i bought the computer, but my old/SnowLeopard computer was barely functioning and had to be replaced. I was not happy knowing that Rosetta is not supported in OS 10.8. I don't think it's supported in 10.7 either.
Again, if there was any way to use those programs in Mountain Lion, I would be so happy, that would be great news.
I don't think it's impossible. I had read somewhere on these forums that the contract with Apple and Rosetta expired and Apple didn't renew it.
please let me know if i'm wrong
