The smaller early machines definitely have total RAM addressing problems. Our oldest Macbook Pro can only address 6GB of RAM, not the 8 you might think you could get. One just slightly older that friends have is I think limited to 2GB.
But, I think so long as you have a Core 2 processor you can run El Capitan (64-bit), if you can feed it enough RAM. In the case of the Mac Pro's you need a patched EFI, but it's out there. Our two cheese graters and the three Macbook Pros are all running it, all roughly 2007 vintage. (The $50 cheese grater is not, mostly because I don't want to put a high-powered video card into a file server. Rather, I intend to run it headless, and 10.7.5 should be just fine for that.) -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
