MP 1,1-5,1 GTX 680 stopped being recognised as Metal (Mojave no longer booting)

[sebster74]

Hi all,

Ive been running Mojave on my flashed 5,1 with a EVGA flashed GTX 680 with no problems for the last couple of months.

However I noticed that my Audio interface wasnt being recognised (which was odd - saffire pro 56 firewire), so I re-installed its drivers. When I restarted, it wouldnt get past the loading screen. It shows a full loaded bar but sticks there. When I boot into recovery mode, and try to re-install the os, it wont allow as it says it needs a metal capable card.

Does anyone have any idea of what might of gone wrong, and any solutions to solve it?

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...

- Kepler NVIDIA GPUs (GT 640/740, GTX 670/680/780, Quadro K5000) note:

If you have a supported NVIDIA Kepler GPU like GTX 680 Mac Edition card, GTX 680 flashed with the Mac Edition firmware, GT 640/740, GTX 670/770/780 or a Quadro K5000 you can't do a USB clean install with it at the moment. The USB installer don't detect that the GPU is a Metal supported card and don't continue the install, it's a bug with Nvidia Kepler GPUs.

To do a clean install, do from macOS with two drives - just select your empty one when doing the install.

Edit: No idea what went wrong with the audio driver

Frustrating that essentially I need to get a new hard drive to do a install of a older version, to then upgrade unless anyone knows why Mojave has just stopped recognising it.

Thank you for pointing out the usb install info.

you can boot your backup and reinstall it over your Mojave disk. The Installer has the nvidia bug only if booted from installmedia (Usb stick or alike).

if you have no bootable backup disk the time is now…

I dont have a bootable backup disk, and guessing as I Cant get access to make one on my OS its not possible to do so?

One of the most valuable things you can do is create a bootable backup (when your back up and running).

this may not work, but is it possible to connect my OS SSD to do a different mac, download the installer for mojave, and then run it to install on the external hard disk?

 

[KeesMacPro]

You could make a High Sierra USB , install it and internally upgrade HS to Mojave.

If you dont have any Backup at all, first I'd remove the MP SSD connect it to the other Mac and make a clone with CarbonCopyCloner to restore all your data with MIgration Assistant after reinstalling Mojave.

I’m also using Kepler GPUs, Nvidia Quadro K5000 (official Mac edition), 680GTX and 770GTX. When installing Mojave, the solution I would perform is to have 2 HDs or SSDs. Remove all the other HDs and just retain 2 HDs or SSDs. The Mojave installer would reside in one of the HD/SSD and the second HD or SSD would be the target drive for Mojave to be installed into. Can be a blank drive or occupied by High Sierra. So far this works on my end and installation would be successful.

It’s a known bug with Kepler cards that installing via bootable USB or by recovery mode does not work.

If your OS stop working after you installed the audio interface driver.

Can you just boot to safe mode and revert the changes?

 

[sebster74]

Frustratingly it wont even boot into safe mode. I tried that, but it does the same of showing a fully loaded bar but wont boot into it.

My next attempt is to take the ssd with mojave on it out, and run the installer from my friends laptop with my ssd as an external drive, and have my drive as the destination. If this work, I'll just have to wipe it, install high sierra and go from there. I have my important documents backed up.

Not sure about your audio interface problem but hope your GPU is fine. This member also had a similar problem as yours in installing Mojave using Kepler GPUs not being detected.

Hi all, thanks for all your help/suggestions. I reinstalled mojave using someone else’s Mac, and bow it’s back up and running. Time to create a bootable back up!!
