A friend recently dropped off his new freely acquired 4,1 for me to upgrade and I've come to the realization that there isn't much I can do with it. The Mac Pro 4,1 - 5,1 firmware update, both the original and patched gives me a 5570 error and I cannot download El Capitan from the App Store for whatever reason. It isn't greyed out, it simply will not allow me to download it.
I don't have installers for anything but Sierra and a (broken?) Mavericks so I'm sorta lost at what to do.
Any advice would be greatly appreciated.
