MP 1,1-5,1 Mac Pro 5.1 complete reinstall to give new user

[Lees75]

Hi all,

I'm at a bit of a loss...

I was running Mojave great...i have now sold my 5.1 so i looked to give it a fresh install for the new owner. So i went into recovery mode erased the SSD...went back to recovery page and then hit reinstall os. It asked me to hold down power button to do the EFI and i have had a black screen since...no video output through an rx560 or the stock 5770..

Now i am just stuck...it powers on with chime.... and then nothing...tried recovery...tried no recovery...any suggestions? USB boot? which card do i use?

HELP!

Thanks.

Start installing an AppleOEM card and try to install Sierra, not High Sierra.

If you are on a superseded BootROM version, you won't install HighSierra or Mojave before upgrading to the current firmware releases for each macOS version (MP51.0089.B00 or newer for 10.13.6, 144.0.0.0.0 for 10.14.6).

There are several pitfalls with Mac Pro firmware upgrades, fully read the first post:

MP5,1: What you have to do to upgrade to Mojave (BootROM upgrade instructions thread)

Please fully read this first post, you will probably find that you have one or more problems described into the various notes below. Mojave will only install if you have upgraded your BootROM to the current release and your Mac Pro have a Metal capable GPU*. If you are trying to install Mojave...

Hmmm it seems i cant install Sierra but i did manage to install High Sierra.... And then nothing... i think i needed to take my 5770 GPU out which i forgot to do..now back to square one

I recently did this using Mojave. I created a Mojave USB key and wiped all the disks which had older Recoveries. I then reformatted the boot disk(SSD on OMC Addin card) as APFS and installed Mojave. The Mac Pro has an HD7970 so I can access the boot screens and supports Metal. Everything worked once done (Boot selector, Recovery, Mojave out of box setup). I did the install from recovery and reset SMC/NVRAM a few times to ensure it worked as needed and wiped my settings.
