If you've replaced the Apple SSD in your Mac with a third-party model and attempt to install Monterey, you may receive an error like: Monterey: "A required firmware update could not be installed." # Updated: November 4th, 2019 based on Feedback from Mac Pro Users user group on Facebook.Monterey: "A required firmware update could not be installed." Updated: November 13th, 2019 MacRumors feedback The 144.0.0.0.0 firmware works with any version of macOS your Mac Pro supports. From here, you can continue using 10.13.6, upgrade, or boot to your 10.14 volume. Under the first screen, look for the "Boot Rom" text. Go to About this Mac, and click system report. After the button flashed, the internal speaker emmitted a long lowfi "boop" sound. I trimmed down the video, as it took about 15 seconds of holding before the button flashed.

If you do not have an EFI enabled GPU (see more about EFI in my Mac Pro Upgrade guide), you will not see any video output. Using the instructions in the previous image, press and hold the button until it blinks. This will not start the Mojave installer, only the firmware. The installer should bring up a message about firmware and a shutdown message. Step 4: Launch the installer and click shut down

Apparently this link was posted this on MacRumors and a few posters didn't read the full instructions and suggested that I was advocating using DOSdude1 on the OS. Much like before, download the OS DosDude1's installer, even though we have supported hardware but with the patcher for 10.14.Ĭlarification: You do not need to use the DosDude1 installer, as you can grab the update via the App store or other sources but I found this easier. The easiest way to obtain the final combined update for Mojave is to use Dosdude1's installer. There's several avenues for this, including the Mac App store, but when I used the Mac App Store route, I didn't get the combined OS installer (The Mojave installer + all the updates to Mojave). Step 3: Download 10.14.6 Combined installerįortunately, firmware flashing does not require updating in a particular order. The next step is pretty straight forward, boot into your install of macOS 10.13 if you haven't already. If you have no intention to upgrade to Mojave or already have it installed., don't worry. You can get old versions of macOS via the Mac using DosDude1's installer if you can't access it. (upside is you can buy a USB case and turn into a very fast USB 3.0 drive afterward or return it). Amazon and Newegg each have 120 GB SSDs for under $20 USD if you need a temporary drive to install macOS 10.13 on.

You'll need a separate volume to boot into 10.13. Unfortunately, this is the biggest pain if you've already updated.

If you encounter issues, try removing additional PCIe cards. Note: some users are reporting they had to remove all PCIe cards sans their storage controller (SATA card) and GPU to install the firmware update. Mojave will not install if you have a non-metal supported GPU. Despite the annoyingness of having to meet the requirements, it was a necessary evil. Vulkan, the OpenGL successor, wasn't quite ready for primetime when Apple originally created Metal for iOS and thus decided to port it macOS. OpenGL has been a thorn in Apple's side for quite some time, as it's been nearly dead for years.

The biggest change for macOS Mojave is the deprecation of OpenGL and OpenCL.
