On a Mac which has never run any version prior to Big Sur (including its betas), it can remain as low as 94. Gatekeeper version numbers are behaving strangely in Big Sur, and seem to be determined by the version installed by the previous system. MRT 1.72 was pushed at the same time versions 1.70 and 1.71 were never released publicly. XProtect 2135 brings some small changes to its detection signatures, as detailed here. It will only complain when the firmware found is older than that expected according to its database. SilentKnight is designed to accept that, as it often occurs in systems with beta-releases installed. For the time being, those using my free tool SilentKnight will see their newer firmware versions being reported in green, but with the newer number. This will take me a little while to assemble, though. Intel Macs with T2 chips which have been upgraded to Big Sur should show a firmware version of 1554.50.3.0.0 iBridge 1.0.0,0.īecause of these changes, I intend compiling a new page giving firmware version numbers for Macs of both species running Big Sur. For those receiving early bird M1 models, I will be updating SilentKnight and LockRattler again to ensure that they work properly with new iBoot versions. Apple Silicon Macs should now be running iBoot 6723.50.2 as they don’t have EFI firmware, that should be shown as the firmware version on some models. This is particularly important to be able to restore sealed copies of the System volume.įirmware versions have changed across most if not all Macs which have been updated to 11.0.1. Apple has published a very long list of all the security fixes in 11.0.1, and this list of its ‘enterprise’ changes.Īpple’s new M1 Macs, when they arrive, will require immediate update from macOS 11.0 which they’ll ship with, at least for the time being, to bring them up to 11.0.1.

To help you catch up with what was released, here’s a quick summary of each update.Īlthough there have been a few reports of problems during installation, once Apple’s servers were working properly this 12 GB upgrade seems to have rolled out quite smoothly to Intel Macs. These were complicated by the fact that from around 1800 UTC on 12 November, for a period of 6 hours or so, Apple’s software update servers weren’t working normally, and for many users returned errors. From Thursday 12 November Apple released a succession of important updates and upgrades for macOS.
