macOS Ventura 13.3, Monterey 12.6.4 and Big Sur 11.7.5 bring firmware updates for all supported Macs

This week’s updates to macOS 13.3, 12.6.4 and 11.7.5 should have updated the firmware of every supported Mac.

I have now completed my check of those updates, and have updated the database used by SilentKnight, and the individual listings here for Ventura, Monterey and Big Sur, for those who prefer to check manually. Apple doesn’t publish any listings of firmware versions.

If you’re using SilentKnight and aren’t intended to update just yet, I apologise that it will now tell you that your Mac’s firmware is out of date.

If you spot any errors, either in SilentKnight or those reference pages, please let me know so that I can correct them. However, as I have obtained these from the full installers for those three versions of macOS, they should be accurate.

For those running earlier versions of macOS, Apple only provides firmware updates in macOS updates and installers. Without updating or upgrading, your Mac’s firmware can’t (and shouldn’t) be updated.

somewhat more sluggish, unresponsive Safari & Monterey after updates today. may be early stages. iMac 2020 intel 5k . already sluggish often nonresponsive before the updates, safari 16 has been somewhat awful, we shall see. fwiw.

Hi,
I have a Macbook Air 6,2 (13″ Mid 2013) and after updating to 11.7.5, SilentKnight informs that EFI needs updating (EFI version found 474.0.0.0.0; expected 478.0.0.0.0)

Seems that the MacOS update did not update the EFI for some reason? The MacBook Air has the original SSD but I have changed the battery a few months back. could that be the reason?

Br,
Jan

EFI check gave the following results:

eficheck –integrity-check
EFI Version: MBA61.88Z.F000.B00.2208232138 (Boot ROM Version: 474.0.0.0.0)
Matching allowlist not found in EFIAllowListShipping. Searching in EFIAllowListAll.
Fetching allowlist data update.
Waiting for allowlist data download to complete.
Downloadable allowlist data update is already present on system or cannot be found on server.
Primary allowlist version match not found for version MBA61.88Z.F000.B00.2208232138 (Boot ROM Version: 474.0.0.0.0).

  I’m sorry to hear that, but your Mac’s firmware should have been updated with that macOS update to version 478.0.0.0.
  I don’t know why that didn’t work, and there’s nothing that you can do about it other than installing a fresh copy of 11.7.5, using the full installer app or in Recovery.
  If that doesn’t work, I recommend that you contact Apple Support.
  Howard.

    Thanks for your quick reply!
    
    Installed 11.7.5 again on an external usb drive and that did the trick! Really appreciate your efforts on uncovering the secrets of the MacOS filesystems, firmwares, Time Machine etc. Numerous interesting technical articles to read!

I am surprised that the firmware on my MacbookAir 7,1 was updated by 12.6.4 because I replaced the SSD prior with a Hynix P31. Before that, I had to swap out the SSD to get the firmware updated. Unless 12.6.3 also had the same firmware, this would be a first for Apple.

  I’m delighted for you. I do know that Apple has been working to ensure firmware updates install more reliably on non-standard Macs. It’s good to know this is happening.
