Rename the mounted disk to Mac Pro EFI Update 2010ĥ/ Run the netkas forum Mac Pro 2009-2010 Firmware Tool.app Rename the mounted disk to Mac Pro EFI Update 2009Ĥ/ Mount the second image for the 2010 firmware. Reboot again.ġ/ Download *both* EFI updater packages from AppleĢ/ Use DiskUtility to convert each disk image to a new read/write imageģ/ Mount the first image for the 2009 firmware. So I manually downloaded them and then had to hack the subsidiary shell scripts embedded in the Firmware Tool app and run them directly by hand.Ġ/ Reboot in recovery mode and disable SIP (Recovery mode, Terminal, csrutil disable ). But the script is run-only compiled and I can't fix it directly. scpt file inside the tool, it's pretty clear what is wrong. And the tool no longer seems to be capable of downloading them (or at least not for me and anyone else getting the 5530 error).
Latest firmware for mac pro 5,1 upgrade#
Root problem: you need to have BOTH the 20 EFI upgrader disk images available so this tool can prepare both the upgrade and downgrade paths. I now have a MacPro 2009 which reports Model Identifier: MacPro5,1 So I hacked the scripts within the tool and ran them directly. I could not get the firmware updater tool to work. Perhaps someone could help shine some light on this. I saved the contents of the ramdisk before I shut it down to attempt the flash I don't know whats keeping it from flashing or at this point its even possible anymore. Remember I'm trying to DOWNGRADE, yes, I'm using all the original OEM hardware CPU/GPU. If I shut down and reboot, firmware is still 00 I did the whole flash procedure (hold power button till light flashes & deep beep) however something isn't right, the apple logo appears and the flash progress bar appears but it goes from 0% instantly 100% (I'm talking blink and you'll miss it) and nothing happens afterward. Okay so under OSX High Sierra, i downloaded both FW packaged from Apple 1.4 & 1.5 with the DMG mounted to the desktop the patched FW utility was able to create a ramdisk and said to shut down. I think I have an idea whats going on, I Believe I have to downgrade to 03 and then to 07? I downloaded the patched version of the FW tool The only thing is it keeps failing to downgradeĬurrent FW is 00 that was supplied with High Sierra FW update I need to downgrade my original 4,1 (that was upgraded to 5,1 via FW update tool) reason being need to warranty it out the system for an unrelated problem.
