Run Snow Leopard in Virtual Machine to retain PowerPC Applications

July 25th, 2011 31 comments

I finally discovered how to run Mac OS X 10.6 Snow Leopard in a virtual machine after I was caught off guard that Mac OS X 10.7 Lion no longer supports Rosetta, Apple’s technology for seamlessly running PowerPC applications on Intel processors. I have enough PowerPC applications (like The Print Shop, my old copy of PhotoShop, and my scanner driver) that I was not going to upgrade to Lion on my home computer, but since I have successfully installed Snow Leopard in a virtual machine, I think I will take the plunge after all (and thanks to this Front Row hack also).

I recently review the compression software Elgato Turbo.264 HD Software Edition, and it was indeed faster than iTunes and QuickTime Player when converting to iPhone-compatible videos, but I noticed that x264 was faster still. Here are the steps you can take for “ultrafast” video compression.
