SYSTEM SPECS
iMac Pro (2017)
Processor: 3 GHz Intel Xeon W
Memory: 64 GB 2666 MHz DDR4
On Board GPU: Radeon Pro Vega 64 16368 MB
2nd Monitor: LG Ultrafine
eGPU HARDWARE:
Enclosure: Mantiz Venus MZ-02
GPU: NVIDIA GEFORCE GTX 1080ti 11GB
Cable: Belkin Thunderbolt 3 Cable (1.6 Feet / 0.5 Meters)
HARDWARE PICTURES:
INSTALLATION STEPS:
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.

COMMENTS:
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: 387.10.10.10.40.105
CUDA: 396.148
Cinema4d: R19.068 (Build RB245443)
Octane: 3.08
@wpratt Nice build guide! I'm not familiar with OctaneBench. How does it compared to GTX 1080 Ti when installed in Mac Pro towers for example?
• external graphics card builds
• best laptops for external GPU
• eGPU enclosure buyer's guide

@itsage Thank you! As for OctaneBench It's my first time running it. It was recommended by @devild. He might have a better answer.
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?

@mize Hey! I haven't tried that yet. But i will give it a shot when i have a free second.
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.
To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
.
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.
