When Apple introduced Macs with Intel processors (what an appropriate moment to consider this!), they brought two relevant changes: EFI, strictly the Unified Extensible Firmware Interface (UEFI) to replace Open Firmware, and the GUID Partition Scheme for disks. Could this be responsible for these problems? This article looks at one obscure factor which can prevent firmware updates from installing: the EFI System Partition. One strong association is with Macs which have had their original internal storage replaced, sometimes even with an Apple-supplied disk, although the most recent Catalina updates and their matching Security Updates have brought relief for some. By far the most frequent problems occur with the iMac Retina 5K 27-inch Late 2015, model designation iMac17,1, but there has been no shortage of similar problems with other models. Many users have reported that their Mac’s firmware doesn’t get updated when they install a macOS or Security Update which is supposed to include a firmware update for that model.
