Hi everyone. I have a question for you. I had a 2007 Macbook. I kept it updated with the newest OS from Apple. Up until the latest one, Mountain Lion. It wouldn't let me install saying the unit was incompatible. I am not sure if that means it is too old? I have a 2008 iMac. Like the Macbook, I keep it updated. It IS running Mountain Lion and just fine. What is Apples OS policy? Do they limit installing new OS on "older" computers?
After the way they treated PowerPC (PPC) users who can say what tricks they'll perform next. But they abandoned millions of PPC users with Snow Leopard. Leopard is the last OS for PPC Macs, and not all PPC's can use Leopard either.
