Installed Sierra on external drive and booted from it on the MacPro. I do not get the error message when trying to download the macOS Sierra Master Beta, it's just doesn't download. Booted from a clean system on an external drive and success. Mine is at the B07, so the EFI updater should work but still will not. It looked like it was going to work but I did not get a firmware progress bar, it just booted normally. Said to shut down and restart holding down the power button until it started flashing. Then running the MacPro 2009-2010 Firmware tool ( ran OK without getting the error). I got by the 5570 error code by opening the MacProEFIUpdate dmg but not running it.
I know we are going to have a lot of questions on Sierra when it hits next week and I would really like to be able to learn the system. I have read that all I need to do is update the firmware from 4,1 to 5,1 and I will be fine.ĭownloaded the update but I get Error 5570 when tying to run it.Ī web search says I need to run Apples EFI Mac Pro firmware 1,5. MacOS Sierra hardware compatibility list (no longer supported):
It must be they feel it is not fast enough even though it benchmarks at 12612.īTW a Apple iMac "Core i5" 2.8 21.5-Inch (Late 2015) benches at 11342 It appears Apple is not supporting an upgrade to Sierra on my Early 2009 Mac Pro 2x2.93.
