I just need the card for the initial flashing and then I can stay on High Sierra without the metal card, correct?
Yes. After upgrading the BootROM you can remove the METAL supported GPU.

You've got prompt to update the bootrom means the installer able to detect you've got METAL GPU (which you're) and also means you're good to go.Ive read a few things and not entierly sure but I'm a able to upgrade to Mojave?
Mac Pro 5,1 (Mid-2010)
High Sierra 10.13.6
Bootrom- 141.0.0.0.0
Graphics Card - AMD Radeon RX590 Nitro+
I see that having an RX580 works but not sure about the 590.
I still have my 5770 graphics card. I opened up the app installer and it tells me to upgrade the bootrom but Im not sure if I should do that or stick with my current bootrom.
I have read the First Post a lot and im not sure with my current Graphics card and Current Bootrom.
If I am good can someone let me know if I am and if not just let me know what I need to do and ill try it. Thanks!
I just am not getting it. I have two MacPros. I put compatible GPUs in both machines. I put the GPUs in BEFORE trying to update the bootRom. The 2nd machine took it. The 1st MacPro not yet. I have a SSD PCIe (is it a SATA III? - I assume so). I took it out after the firmware didn’t work. I guess. The previous Boot ROM was MP51.007f.B03. Now it says 138.0.0. Is that the right direction of what you would expect from the HS install?
In trying to do the 1st MacPro I put the old GPU back. Hoping that’ll take.
The problem is I already have High Sierra installed on this Mac as my boot, and I’m not sure how that works. When I try to install Mojave it says I have to install high Sierra first. But I’m in HS. So I’m trying to be patient. But it’s been taking hours and hours so far.
I have trashed all High Sierra install apps. I need to know how to install the firmware. Is there a more direct way?
I don't know how I used the wrong Mojave installer. I got it right from the App Store. So I'll put the GeForce GTX 680 back in and try Mojave again.If you read attentively the first post of the thread you will see that 138.0.0.0.0 is the first Mojave BootROM. High Sierra ends with MP51.0089.B00 and Mojave starts with 138.0.0.0.0. If you upgraded to it, you used the wrong Mojave installer.
138.0.0.0.0 BootROM is not enough for the current Mojave 10.14.5 installer to work, you need to upgrade to 144.0.0.0.0 with the instructions on the Mojave installer.
Read the first post, everything needed is there. Pay attention with the notes.
you did not flash to MP51.0089.B00 with the latest HS fullinstaller! before mojave
i think his second is not, or?

138.0.0.0.0 is the first Mojave BootROM, so the first part is done. With a 10.14.0 createinstallmedia USB key, the install would go on, but with a 10.14.5 Mojave installer he still neededs to upgrade the BootROM from 138.0.0.0.0 to 144.0.0.0.0.apple says you must on MP51.0089.B00 before install mojave?

Yes.And how at this point? Put the metal GPU back, trash all the Mojave installers and install again?
Do the 1st post "If nothing above works for you, try this"I bought a used Mac Pro 5.1 running Mojave and the seller booted from a Mojave Installer USB Flash Drive to erase the system SSD and data HDD, both formatted as APFS before and after erasing.
Now when I try to boot from the same USB Flash Drive, it doesn’t show up as a bootable volume.
The patcher file on the same drive says the computer can already run Mojave, no patch necessary (when running it while booting from an old bootable Lion drive).
Since I also tried to boot from a High Sierra Flash Drive with no success, I should probably install Lion and then move up from there? Should I remove the SSD first? Thanks!
Sierra and El Capitan installers are not available for download anymore on the App Store despite having an official page with screenshots and a Get button.Do the 1st post "If nothing above works for you, try this"
