Anyone get Big Sur working with egpu on macbookpro9,x?
Purge-wrangler works. The eGPU gets detected. But since the dGPU conflicts it won't use the eGPU. Anyone get their system working with this setup?
I have a 2018 MBP 15" running 11.4 and it works fine with my eGPU. Apparently I'm a unicorn because everyone else seems to struggle where I don't, but I've done this over several times and get the same results each time if I wipe out Boot Camp and start over. One caveat is that I use an external display, so if you don't then these steps may not work for you. Pretty sure that I've written my instructions in previous posts, so check that out in case I've forgotten something, but here's what I do from start to finish:
1. Install Windows via Boot Camp
2. Get Windows all set up and download the DDU app
3. Download the lasted AMD driver, launch and save wherever you want to put it.
5. Plug in the eGPU and boot to Windows. As soon as I see the swirling circle beneath the logo, I close my MacBook.
6. For me, Windows recognizes the eGPU and pushes video to my external monitor, but it's a generic driver, so I need to update the driver.
7. I launch Device Manager and select Display Adapters and choose the AMD GPU, then choose to update the driver with the one that I downloaded.
8. After install, which can take several minutes, I restart the Mac, hold option and choose Boot Camp. Once again, as soon as I see the spinning circle of circles, I close my Mac.
So, I don't get the AMD Radeon software, but my eGPU works just fine. Any new driver updates, I just download, open and save in a specific folder, then open Device Manager and update the driver. Also, I have set my external display as my primary display and choose not to display video on my internal monitor since I don't use it. You can if you want as it does work for me, but I have plenty of real estate on my 34" monitor, so I don't.
@psypryss, given the configuration listed in your signature this is one that has an intel iGPU, Nvidia dGPU, and you're tying to use an AMD eGPU, right? For this, you need to use purge-nvda if you haven't already: https://github.com/mayankk2308/purge-nvda
Thanks for your build links. They’ve been helpful to get my setup working.
@aae, Thanks. I have win10 working. Just not Big Sur.
