To put it simply, it was a piece of translation software to turn PowerPC instructions into Intel instructions. Softonic offers OS-X 10.7.5 as a download 'from an external source'.Just a heads up for those Mac OS X users out there that may be using older applications from the PowerPC days (so those G3 and G4 CPUs that powered the Powerbooks and other Apple machines of that generation) – Rosetta support is being removed from the upcoming Mac OS X 10.7 (Lion) operating system.īefore I go any further, what is Rosetta? Where can I get an installable copy of OS-X 10.7.5 (Lion)?Īpple no longer offers it, but does have OS-X 10.8 (Mountain Lion) for $19.99, but says it requires a 'mid-2009' Mac mini. Should I forget about Lion and go Mountain Lion or Yosemite? How will they run on my mini?Ģa. Can such an 'Intel' app still require Rosetta?ġc. I've heard that Quicken 2007 won't run on Lion because it needs Rosetta. Snow Leopard's Activity Monitor shows it as an 'Intel' application. I use the latest upgraded Quicken 2007 heavily.

How well will Lion or above run on my Mac mini? Or, I could run them from an old MacBook maxed out at 10.6 networked to the Mac Mini's hard drive.ġa. I've decided that I can forget about Rosetta compatibility for most work if I make a bootable 10.6 CD and restart the Mac mini from it when I need to use that's those old apps.

I bought this year's version of TurboTax and found that it requires OS-X 10.7.5 (Lion) or greater. I use a Mac mini running OS-X 10.6.8 (Snow Leopard) because I need Rosetta for two very old apps that I use frequently.
