[Solved] [SCRIPT] PurgeWrangler: AMD + NVIDIA eGPUs for all Thunderbolt Macs
TB3 devices also cannot force eGPU to accelerate internal display. You can force apps, however. See set-eGPU.sh in my signature.
Thanks again, I will read more carefully.
My 2016 MBP is still on 10.13.3 with the old method. I haven't been using my eGPU all that much lately so I haven't been keeping up on things as close as I should. Am I better off staying on 10.13.3 with the known working method I have or is everything working well on 10.13.6 with this new method? Any major complications or special methods for updating to this new method?
@fanacess This is mentioned succinctly on the GitHub page. System Recovery restores previously backed-up kernel extensions instead of uninstalling (which just re-patches in-place). Sanitize System fixes kext permissions and rebuilds the kernel cache.
Success here too !
Happy to pop a GTX 970 in there once we feel Nvidia-ness can work 🙂
Amazing work guys - I was almost ready to buy a TB3 iMac... so that in itself is worth a donation for your hard work?
how did you connect the egpu to your iMac? Do you have a second external monitor? In the past, I connected the egpu to my iMac using a TB3 to TB2 adapter, then connected an HDMI cable from the egpu to my external monitor. I set the external monitor as the main monitor, then I could use the egpu. The iMac doesn't start with purge wrangler, on the second monitor I see the wallpaper, but I can't log in. Thanks for your help!
Worked! Upgraded to 10.13.6 on a MacPro6,1. The trashcan has a little more life left in it. Recognizes my Radeon Vega Frontier Edition as an External GPU. Using a Sonnet eGFX 550 with the bigger PU unit. My Compute score Geekbench 4 was 172393 (Compute API: Metal). Connecting the eGPU with a USB-C to thunderbolt 2 adaptor to the MacPro.
Thanks for everyone's work on this board. Invaluable resource for someone who doesn't do a lot of tinkering / or computer building.
Hello everyone, I’m newbie here!
Thank you so much for the game changing script!
I’ve had a slight issue regarding the recognition of Graphics.
My environment is:
I just installed and executed Purge-wrangler and it’s done nicely, no errors.
My MacBook recognize GTX970 and my second display started working.
Then I did Geekbench4. Score looks way better than onboard CPU.
OpenCL score has been improved from 13738 to 88755( Intel Iris 550 to GTX970)
However, when I check About This Mac > Overview, Graphics is still Intel Iris Graphics 550.
I mean, my GTX970 seems functioning properly in my MacBook though, the text of Graphics doesn’t change.
Do you guys have any idea to fix this?
It’s not a huge problem for me as eGPU is already working but I just want to know why.
Thanks in advance!
@yasushi_ikeda read troubleshooting guide about this Mac section.
@mac_editor thank you for your quick response and im sorry for bothering with this. I should of read the guide first. The problem was all solved 🙂
