Now that the update has been successfully installed, you can re-enable SIP in Recovery with the command csrutil enable and install the software update to macOS Monterey as usual. You should now see a higher version than before, which means that the update was successful. > "Hardware" -> "System Firmware Version". Once your Mac is booted again you can check the new firmware version number in "About This Mac" -> "System Report." -> "Hardware" -> "System Firmware". This may take a few minutes and your Mac will reboot a few times. Once this command has been executed successfully, shutdown your Mac and start it again after it’s been completely off. Sudo bless -mount / -firmware /YOUR_MODEL.fd -verbose -recovery Of course you have to replace the path to the firmware file with the correct path. Now open a terminal and enter the following command. You can find your Model Identifier in "About This Mac" -> "System Report." -> "Hardware" -> "Model Identifier". The filenames contain the shortened Model Identifier.
Now find the appropriate file for your Mac. Here you will find all EFI firmware files that are included in macOS Monterey. Open the unzipped folder and navigate to the directory "AssetData/boot/EFI/EFIPayloads". One of the folders is called "com_apple_MobileAsset_MacSoftwareUpdate". When you open the file, you should see a folder with two files and two folders in it. You may have to copy the file out of the installer to open it.
There you will find a file named "SharedSupport.dmg", open it with a double click. Now navigate to the directory "Contents/SharedSupport". Rightclick the App and click on "Show Package Contents". If you downloaded it through system preferences you can find it in "/Applications/Install macOS Monterey.app". Enter the following command and restart your Mac.Īfter your Mac is powered on again find the installation image. Here you have to open the terminal in the menu bar in Utilities. This will take you to the macOS Recovery. You do this by turning off your Mac and holding CMD + R when you turn it on again.

It doesn't matter which method you use, but I would recommend to download the update regularly, so you can install this update later as usual and you don't have to bother with third-party software like InstallInstallMacOS.Īfter the image is downloaded you have to disable SIP. You can download it either directly from the System Preferences as a normal update or with tools like InstallInstallMacOS. )įirst of all you need the installation image for macOS Monterey. In my case, the SSD is a Sabrent Rocket nano with 512GB in a 2017 13" MacBook Pro.īelow I'll explain how you can work around this problem. The reason for this is that macOS Monterey needs an EFI update and for some stupid reason this can only be done with the original Apple SSD. If you try to install the update in the normal way, it may happen that the previously installed macOS version starts again after the update. In the worst case, your device could become unusable.Īs many of you probably already know, macOS Monterey cannot be easily installed with a third-party SSD. I assume no liability if something should go wrong in the process. First of all: This tutorial is mainly for experienced users.
