Problem upgrading Mid-2012 Mac Pro from High Sierra to Mojave
I have a Mid-2012 Mac Pro running High Sierra (10.13.6) and have purchased a Mojave install USB stick from Amazon. After booting from the USB stick, a macOS Utilities window comes up and I select “Install macOS” and click “Continue.” An “Install macOS” window appears which says, “Installing Mojave on this Mac requires that all graphics cards have Metal support and that FileVault is disabled.” System Report shows that my Nvidia GeForce GTX 980 Ti supports Metal and I have FileVault off (it was never enabled). The only option from that window is to Quit.
Any help would be greatly appreciated.

I would be suspicious of purchasing anything to install an Apple OS from Amazon. Why don’t you make your own USB stick so that you know what you are getting is an “official” release of macOS Mojave from Apple. There is no telling what is on that stick or how old the software is.
Here is Apple’s page for installing older versions of macOS:
How to create a bootable installer for macOS
Sorry I don’t have a better answer for you, but your next step might be to post on the official Apple forums and if you tell them you bought an USB stick with Mojave on Amazon, they are not going to support you.
If I remember correctly, the firmware on my 2010 Mac Pro needed to be updated before I could upgrade to Mojave. There were steps to update the firmware that needed to be followed before installing macOS. Maybe the 2012 Mac Pro doesn’t need this? But that is something to look into.

Thanks John. In re-reading the web page for “Install macOS 10.14 Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012)” I now see that my graphics card is not one of the two Nvidia cards listed as compatible. The first time I looked at it I assumed that the System Report check for Metal support was sufficient, but I guess not. I also wasn’t aware of the page you referenced for downloading old OSes and couldn’t find it anywhere but Amazon. I appreciate your input.

Glad you figured it out. Apple has been very selective in what they support. 🙁

I found a Mojave installer direct from Apple that I was able to use, but many of my apps ran slow in Mojave (and some not at all) so I reverted back to High Sierra. Interestingly enough, that installer never made reference to my graphics card and simply installed from the .dmg.
Thanks again.

You’re welcome. It’s interesting that the installer from Apple behaved differently. This is why I recommended you get it directly from Apple. What I have found is that Apple keeps updating their installers. I always save them on a separate hard drive in case I need them and I’ve found that sometimes the one I saved will stop working while downloading a new one will work. Maybe they updated the allowable graphics cards in the installer.
I have Mojave on my 2010 Mac Pro with a Sapphire Radeon HD 7950 Mac Edition graphics card and it seems to be fine performance wise, but some software did stop working. I use Final Cut Pro so it is optimized for macOS and runs better with Metal support. I actually have a Yosemite partition for running older 32-bit software.

All good points, John. I appreciate all your input.
