With all this hassle concerning the Nvidia web drivers not being available for macOS 10.14 I too switched to a RX 580 card (Gigabyte). Works flawlessly and seems about as fast as the Nvidia GTX 980 Ti I used before. Got the card for $200 - for the flashed Nvidia card I payed around $1000 some time ago!
Installation was easy and the card works well (besides the missing boot screen which currently is no issue). Installation of macOS 10.14 was a bit of a PITA since 10.13 must be installed first and from that 10.14 can be installed. (Mac Pro 5,1 Mid 2010 for me).
I am mostly using Photoshop, Lightroom (still runs sluggish as hell - shame on you Adobe!) and Phase One Capture One which utilizes the GPU very well.
Now I am curious how the upcoming Radeon VII cards will perform. Anybody have any idea how they will stack up against the current Nvidia cards?
@thomas_geist Reports from an ODM in Taiwan said the Radeon VII is very competitive with RTX 2080 in Windows gaming performance. This new GPU is not working in macOS atm. Apple has started adding PCI ID 66af into AMD10000Controller.kext and AMDRadeonX5000HWServices.kext. I'm hoping Radeon VII makes it into the 2019 Mac Pro. A launch at WWDC2019 would be awesome!
So the PowerColor Radeon Vega 56 arrived today. I did order the power cables (6 pin and 8 pin) and they plugged right in. However, when I powered up the Mac Pro, nothing but a black screen. Running OSX 10.13.6. Had to put my GTX 120 back in so it would work. Thoughts?
UPDATE: I did check the cables with a voltmeter. They are putting out 12+v from pertinent pins. The card lights up, fans don't come on yet, and no video.
Mac Pro 5,1
I know that a 2011 Mac mini can understand my EFI app but never thought that you can actually run it on a 2010 Mac Pro. Did you try to tick on "Launch on startup" setting and then boot with a single GPU only (eGPU disconnected)? Does it show the custom EFI boot screen and can you continue booting into macOS/Windows? (don't hold down the Option key on the second startup).
Hi @goalque, sorry for the long delay in testing your EFI app on the Mac Pro 5,1. I tried it this morning and your app was able to load up (w/o holding OPTION key) after I selected "Launch on startup". The connected Thunderbolt 3 eGPU was present as well. The next step of boot is what I got stuck at. The EFI boot loader could not advance into either Windows or macOS partition. I followed your instructions on automate-eGPU EFI page to remove apple_set_os.efi and change mux configuration to 1.
Booting without your EFI app and eGPU connected would let me get into Windows partition but not macOS. The system would hang 70% of the way and I could even hear the whooss fan noise from RX 580 eGPU. I attempted multiple hot-plugs from warm boot too but no go with macOS Thunderbolt 3 eGPU on this 5,1 + Titan Ridge AIC just yet. Thunderbolt 3 dock like the Mantiz Titan worked well.
@itsage I see a 3-5 pin short mode on you thunderbolt header cable. What does that mean? It is required for the Thunderbolt AIC to Work? Thanks.
Shorting these two pins forces the Titan Ridge AIC to activate even when there's no Thunderbolt 3 devices connected prior to boot. It's helpful during the set up process so that you know the Thunderbolt 3 controller is active and the operating system should be able to detect the AIC [more info here]. I've observed this power-active mode of the Titan Ridge card interferes with Sleep/Suspense mode in Windows 10 and Linux.
Did you get any progress with this setup? Been able to get video out of the eGPU graphics card?
Now running macos 10.14.5 beta 2 and I'm able to get video output through the eGPU as well!
That one indeed. So some details:
Booted into Windows with the monitor plugged into the Vega in the cMP. Switch monitor to the RX 480 in the eGPU, gives display. Then warm boot into macos, wait a minute and there you go, video through eGPU.
Let me know if you'd like any more info.
On another note, I've also got the Asus MB169C+ USB-C display to work nicely with the Titan Ridge (use the minidp --> dp cable included between your GPU and the Titan Ridge, then plug in the MB169C+ into one of the TB3 ports on the Titan Ridge, works instantly)
