We had a bizarre case, rendered this 21″ iMac 2017 model completely useless after a corrupted software update. It caused the system to load only in recovery mode with the following error:
macOS could not be installed on your computer An error ocurred while updating firmware. Quit the installer to restart your computer and try again.
No matter how many restarts have been performed it still will not load into the user system. Causing the user to lose access to their data.
Although these model Mac’s are not near ready to run Big Sur, Apple keeps pushing these updates to the older Mac’s, which eventually bricks them, causing unnecessary stress to the owner. One gets to wonder if it’s their way of “encouraging” Mac owners to buy themselves a new Apple device every 2-3 years, even if their previous generation device was working perfectly fine prior to the update?
Failed iMac Update Repair
This issue could be resolved 2 ways, if it was a firmware corruption we would probably have to work on a firmware level and reprogram its internal flash memory with a programmer.
But luckily, this particular iMac suffered from partition corruption. Seems like the part of the operating system holding the system updates got corrupted and haven’t managed to handle the update procedure.
Due to it has been a corrupted software issue, rather than firmware, we could repair the software partition to regain access to the system.
Of course, before we did that, we had to ensure all customer’s data is backed up safely, in case repair does not go by plan.
