Yes, it is ... with a patched com.apple.telemetry.plugin

google mojave2core ...

But I see you have a radeon HD 5670 which is a no go because of the need for sse4.2 in Mojave AMD drivers.

I suggest you to change it for a cheap nVidia GT 600 or 700 series.

 

Works for me.

It's probably much easier to simply replace the Mojave version of the plugin by that of, say, High Sierra. Patch or replacement is necessary in order to circumvent the SSE4.2 CPU requirement imposed by default in Mojave and which impacts all Core2Duo/Core2Quad platforms such as yours, based on Q9950, a CPU that is SSE4.1 only. Without this trick, your system will KP and reset/reboot when booting Mojave. There are dozens of threads on the matter and you may look here, for instance, for procedure details in respect of this telemetry plugin matter.

 

With regards to graphics cards, it'll have to be Kepler generation GeForce GT600 or GT700 Series only, not Fermi generation or otherwise. Very important since Mojave only supports nVidia cards of the Kepler generation. For AMD cards, you need models with GCN1.0 architecture minimum.

 

Plenty of threads on the matter of graphics cards for Mojave on this forum and elsewhere. You can run a search.

Is it possible to make a driver rollback from Mojave to Sierra to use the AMD ATI Radeon HD 5670 on Mojave? I did that on High Sierra with succes.

Or can I use a Sapphire Pulse Radeon RX 560 4 GB with my Gigabyte GA-EG45M-DS2H motherboard? Out of the box?

AMD Radeon RX 560 is supported. If you run a Search for that card, you'll find threads about it being successfully used in Mojave.

 

You need to understand that Mojave restricts graphics support/acceleration to cards that are Metal compatible; this because that's the technology Apple have chosen to pursue in a switch from OpenGL. As such, rolling back older kexts from an earlier macOS release for an older unsupported card is limited both in terms of success and time. I've read that this is no longer working in beta versions of 10.14.4. Let's be realistic: a card that was not supported in High Sierra without kexts rollback has even less of a chance to work in Mojave.

It seems though RX 560 does not work OOB on older Core 2 systems running Mojave. 

 

I've tested the RX 560 on 2 different Core 2 Quad systems that were running Mojave 10.14.2 (at the time). I used com.apple.telemetry.plugin from 10.13.6, SMBIOS 14,2 and -no_compat_check. It would black screen and reboot right before the GUI loaded. Both systems worked fine with NVidia cards I simply removed the NVidia card, disabled NVidia Web and popped in the 560.

 

I also tried fresh installs and other attempts. Using DOSDUDE1's patcher to 'completely' patch Mojave for a 10,1 SMBIOS. This allowed me to get to the desktop with the RX 560 but it would only show 7MB of RAM for the card under About This Mac and there was no hardware acceleration.

 

In both scenarios I tried removing Whatevergreen / keeping Whatevergreen along with variations of the below settings.

Device ID ATI - RX 560 - 0x67FF1002

Inject EDID - Vendor ID 0x1002

Load VBIOS

Inject ATI

RadeonDeInit

 

With Sierra and High Sierra on these Core 2 Quad Systems the 560 worked OOB

 

 

I dropped the 560 into a newer i-7 system and it worked OOB on Mojave 10.14.3. It does not seem to work on the 10.14.4 betas like you've said.
