I was now actually able to solve this myself and totally by chance. Recently upgraded to a Vega 56 and in order to get it running, I had to change my SMBIOS (more info here). Well, guess what, shutdown and reboot are working again!

Big surprise, I actually got it running now! Changing the SMBIOS to iMac 18,2 did the trick! It's now running on HDMI at least. DisplayPort doesn't appear to work, but I will look into that this evening. EDIT: After some googling, DisplayPort is now working too! Plus, shutdown and reboot seems...

I had already tried that, but no luck. :/

Yup, got the adapter yesterday, still no luck. Cheers for the tips! So, what I've tried so far is changing the SMBIOS to MacPro5,5 directly through clover, as that's the only one of the mentioned models that Clover supports configuring out of the box, but it won't boot since the MacPro5,5...

Ok. Will order a VGA to HDMI adapter for my second monitor, will try again and report back on Saturday. Many thanks for your help so far @pastrychef !

Ah, good call. But it appears I can't change the refresh rate through the monitor's settings. On DP I get a 3440x1440 60hz signal according to the settings panel and on HDMI a 3440x1440 signal, which is both to be expected, just not as a black screen.

What resolution could that be? I have a 3440x1440 monitor and I doubt there could be something it doesn't support? The Apple boot is in the correct resolution btw. Maybe I can somehow enforce a resolution through clover?

Yes, that was my impression too. If I remember correctly, I had screen sharing disabled and ssh gives me a connection refused. However, the machine does show up in my network and I'm able to ping it, so I assume it's running fine - just no image.

Cheers for the tip. I had actually tried that already, but just tried it again for good measure - still no luck.

Anyone? Still haven't been able to get it to work I'm afraid...

Dear community, A couple of days ago, I made the switch from my old GTX 770 to the Sapphire Vega 56 Nitro+ GPU. Rather foolishly, I assumed it would work out of the box and therefore didn't do any research on potentially required kexts etc. Well, turns out, it doesn't work out of the box and...

Nope, that one didn't do it for me, and of course unusable, as you said. But could it be a graphics issue? I see you're running a 7-series card too ...

Has anyone of those running into issues updated to the Mojave public beta? Would it try out myself, but currently don't have the time ..

Thanks for the tip, tried it just now, however, still no luck I'm afraid...

Yes, I have, but still no success. Hoping that 10.14 might do the trick, once it's out ...
