I have a Mac Pro (6,1) with dual AMD FirePro D300s and I think they're failing. It seems to be a common issue on the Apple forums. My machine is freezing 4-5 times a day.
I bought an Akito Node and AMD RX 560 and have it connected via Thunderbolt. I ran the automated epu script like it says to do on the guide and it seems my Mac can read the Akito. It picks up the Akito under Thunderbolt and under Graphics\Displays the Video card is found...but it's listed as "Display". The vendor is listed as AMD. However, I can't get anything to run off of it. Everything still runs off the AMD internal cards and I'm still getting the crashing and freezing and inability to wake from screen saver.
What macOS version is your nMP running?
Goalque's automate-eGPU.sh script is good for 10.12.6 and older only. For High Sierra 10.13, you need Goalque's automate-eGPU app for AMD. Please uninstall the script then download the installer to use your RX 560 eGPU in High Sierra.
With regards to your D300 dGPUs. If the nMP is a few years old, it doesn't hurt to take it outside for a dusting. Applying fresh thermal paste will also help.
Sorry....that's the one I used. I installed that and it just doesn't seem to fully recognize the AMD RX 560. It found something there, but can't get any monitor to run off that card. Is there a way to make programs or monitors run off that card? When I plug a monitor directly into it, it just stays black.
Yes. Hold down Command + R, and reinstall macOS 10.13.
- "Macintosh HD" selected in the System Preferences / Startup Disk
- Thunderbolt cable connected to the Bus 0 (ports 5 or 6)
- nothing plugged into the HDMI or other TB2 ports
- XFX? Get another brand card
If all points are checked, it's plug-and-play.
