I strongly recommend that you consult Duo’s excellent report on EFI firmware security and updates, from which I have extracted initial data for this article. EFI firmware updaters are now only distributed as part of macOS / OS X updates and upgrades: Apple does not provide them separately. Consider upgrading to Sierra or High Sierra as appropriate.

Install those, and check the firmware version again. If your EFI firmware version seems out of date, download the last Combo updater and/or subsequent Security Updates for the version of macOS / OS X which it is running, from Apple Support. If your firmware version is more recent than those given above, please let me know in a comment, so that I can improve the above listing for us all. That is a higher number and thus more recent than 010F.B25, as the major version is greater, even though the minor version is lower. So in that case, the major version is 0151 (337 decimal), and the minor version is B00 (2816). The firmware version is then given in hexadecimal, with the major version first, followed by the minor version. In that, IM171 is the model identifier, here iMac17,1. The Boot ROM Version given in that Hardware Overview typically looks like In System Information, in the Hardware Overview listing, this is given as the Model Identifier.

If you’re not sure how to discover the model code of your Mac, use the About This Mac command at the top of the Apple menu, and click on the System Report… button. The significance of this is unclear, but it suggests that the first EFI firmware updates for some models had problems, and have since been replaced with 00B versions in that supplemental update. In its revised list, included within the Supplemental Update, some of those changed to 00B, as noted above. Observation: in Apple’s initial list of versions for High Sierra, the minor versions were universally B00.

I don’t know whether this changed with 10.13.5, but no EFI firmware update is listed there for that model. Of these, only the Macmini4,1 was not updated in 10.13.5.Īpple doesn’t list the MacPro5,1, but Jay in a comment below reports it as being 0085 B00 following 10.13.4. Of these, only the MacBookPro7,1 was not updated in 10.13.5. Neither Apple nor Duo list the MacBookPro11,3, but iawhciwc in a comment below reports it as being 0142 B00 I suspect that this should now be updated to 0146 B00. MacBookPro12,1 0176 B00, may be 0177 B00 with latest betas.Of these, only the MacBookAir3,1 was not updated in 10.13.5. Of these, the MacBook6,1 and MacBook7,1 were not updated in 10.13.5. Of these, only the iMac10,1 was not updated in 10.13.5. iMac14,1, iMac14,2, iMac14,3 0130 B00, or 0122 B00 for El Capitan?Īpple doesn’t list the iMac12,2, but Ariel in a comment below reports it as being 004E B00 following 10.13.4, and I expect that to have risen to 004F B00 following installation of 10.13.5.

Since the initial release of High Sierra, I have maintained this list from those firmware updates included in each system software and security update. Which displays the recognised EFI firmware versions known to the eficheck tool (High Sierra only). Ls /usr/libexec/firmwarecheckers/eficheck/EFIAllowListShipping.bundle/allowlists You can obtain the latest list by typing the following in Terminal: Because this latest version of macOS includes a new tool, eficheck, which performs a weekly check on firmware, there was a list of known firmware versions included in that. At least, it didn’t until it released macOS High Sierra. Please refer to that more recent article instead.Īpple doesn’t provide a list of the current EFI firmware versions which should be installed on each model of Mac.
