2017 27" iMac Pro (Vega64) [7th,10C,W] + GTX 1080 Ti @ 32Gbps-TB3 (Mantiz Venus) + macOS 10.13.6 [wpratt]
1. Install card into enclosure. The card I used has two 8-pin inputs. It required using two 6-pin + 2-pin configurations to power fully.
2. Get your eGPU set up to be quickly/easily plugged in. When the scrip is running, you only have 20s to plug it in.
3. Disable SIP. Using directions here:
4. Run Script. Again, using directions here:
5. Make sure eGPU is unplugged on reboot.
6. BEFORE logging in, plug in and power on eGPU.
7. Log in.
My only goal for this build was to run Octane Render with Cinema4D. I do not have any Ghost head plugs, or displays out of the enclosure. My system monitor and secondary monitor are still running on the onboard GPU, while the eGPU allows Octane to run. Software/ Driver versions are:
OSX: 10.13.6 (17G65)
Nvidia WebDriver: 3188.8.131.52.40.105
Cinema4d: R19.068 (Build RB245443)
I see you're not actually using the egpu as a display driver. By any chance did you just try it to see if it works?
Thank you for sharing the results. That scaled very well with two GTX 1080 Ti eGPUs.
I have my iMac Pro + 1080TI + Sonnet Breakaway working fine, but one thing missing is the eGPU icon in the menu bar… just wondered whether anyone might know why this is?
Everything else appears to be working ok, just missing that icon.
Has anyone here had luck on Bootcamp? I am unable to get the TB3 ports to work.
No response from any thunderbolt device. I have tried latest Intel drivers, the thunderbolt controller disconnects a few minutes after startup.
Has anyone with a imac pro had a smiliar situation?
I'm finally back to using MacOS a bit and would like to get egpu working again in MacOS.
For those on this thread who have it working (for display purposes), can you please post what fix/scripts you used?
I've not updated to Mojave yet for fear it will break bootcamp.
