How to check your Mac’s EFI firmware version

The iMac Pro, 2018 MacBook Pro with Touch Bar (MacBookPro15,1 and 15,2), 2018 Mac mini and 2018 MacBook Air all use a different mechanism for firmware updates, managed by their T2 chips. I am extremely grateful to Pico, who provided a complete listing, to all those Mac users who have confirmed version numbers as well, and to Pico who kindly gave me a script to unscramble numbers from updates. See below for further information about this model. See below for further details of how to obtain this. This is made up from the model designator IM144 = iMac14,4, the code 88Z or sometimes AAPLEFI4 or AAPLEFI5, the version number 0190 B00, and the datestamp of that version 1809171521 = 18/09/17 15:21.

The following lists give the EFI firmware versions supported in the Mojave 10.14.6 Security Update 2020-004 amd High Sierra Security Update 2020-004 released on 15 July 2020. These changed in the Mojave and Security Updates released on 30 October 2018: the version number given in System Information is now completely different to that offered by the definitive system tool eficheck, and those installers contain many EFI firmware updates which don’t reveal their version numbers (in either numbering system). Until 30 October 2018, it provided usable version numbers in System Information, and macOS installers and updaters also gave details of any EFI firmware updates which they contained and installed. Apple doesn’t provide an official list of the current EFI firmware versions which should be installed on each model of Mac.
