For older Macs and earlier versions of macOS, please refer to the previous listing of firmware versions. If your Mac is still running an earlier version of macOS, such as El Capitan, then you should refer to version 2 of this list instead.

That displayed in System Information uses five decimal numbers separated by dots, e. One numbering system used by the eficheck tool still uses the older system with two hexadecimal numbers, e. However, in Catalina eficheck now also gives version numbers using the new notation.

The full eficheck version number is likely to resemble IM See below for further details of how to obtain this. Models with T2 chips are presumed to be running the same versions. If you see evidence to the contrary, please let me know. I am extremely grateful to Pico, who provided a complete listing, and those Mac users who have confirmed version numbers as well.

They are also unable to run eficheck. The simplest way now is to run either of my free tools SilentKnight or LockRattler, available from their product page. I will update it to this new set when they have been distributed in security updates to High Sierra and Mojave. In that, is a new model identifier.

The firmware version is then given in the following four numbers. For almost all models at present, this appears to be 0. If the installed version of EFI firmware has a version which is lower than that shown, you can try installing macOS Catalina a second time.

Then check the firmware version again. EFI firmware updaters are now only distributed as part of macOS updates and upgrades: Apple does not provide them separately. Normally, this is run automatically every week, and you should be informed of any issues which it raises.I believe the installer is simply looking for a small partition EFI to put the recovery info for the version of the OS you are trying to install. Older versions of Mac OS did not do this. When you upgraded to, say, Mavericks, when you did a system recovery off the hard drive, you always went back to the version that came with your Mac.

So, I think that if you give the installer a small partition with the correct name, format, and size, it will be happy. Read the part of the article telling how to create the EFI partition, and decide if you want to give it a go. I do suggest you try this on a spare external drive or memory stick before touching your current operating system.

The internet recovery downloads the install app and runs it, so I believe it will still look for the EFI partition as it wants to update it. Spent hours trying to re-create your problem by installing HS on an external drive using every format possible using Disk Utility.

No matter what I did, I never got the message you saw. Did learn a bit about Disk Utility. Screen Shot at 9. On the attached list, with HS running on the external drive, the external drive is disk2. Disk0 is HS on my internal drive, Disk1 is Catalina on my internal drive.

I would try the following if you have the resources. Create a USB install of the Mac version you are trying to get to. Shut down, disconnect your external drive, and set it aside. If you ever get the upgrade working, you can literally copy all your data and apps from it.

Boot to the USB install drive you created. Try to install the MacOS on this clean disk. If it works, you know you can do a clean install. Think that means it wants something from the internal disk you do not have.

Time to get a suction cup, and take apart the iMac. Great stuff! If he does a clean install, and has access to the Install app for version he wants, he can install any version he wants. There was a time you could only get the next version from the App store if you were already running the previous version. I believe High Sierra or Mojave changed that, allowing you to upgrade directly from older versions.

Therefore, you could download the Install app. The Apple App store will not let me download the Install app for either. As a result of this forum, I learned about dosdude1. I know MACalot personally.

I think it is very important that the current HS drive contents be preserved safely. Backup the entire user folder, and backup the top level Applications folder. I encountered the exact same error. Get message from installer that "You may not install this volume because the computer is missing a firmware partition. Seems from other forums that it is related to recovery disk partition on OEM internal HDD which is completely unusable in my case.

Advice welcome. Thank you, Bgeeoz. Will give that a try. Appreciate your advice. I would try the following if you have the resources; Create a USB install of the Mac version you are trying to get to.To start the conversation again, simply ask a new question. I suspect this may not have been done correctly, hence the current issue? Or perhaps it is something else, I do not know.
