[Solved] [SCRIPT] PurgeWrangler: AMD + NVIDIA eGPUs for all Thunderbolt Macs  

I can confirm 11.2 Beta works fine with the latest PurgeWrangler.

Got a hand on rtx 3070, i wonder if the Purge works on these new cards, as for the web drive, should I use the newest drive for 3070? 

Thank you

@nelsonfeelscool, Sorry but macOS hasn’t supported Nvidia cards in years. If you’re planning on using Windows, that’s about all you can use it for. PurgeWrangler isn’t going to help at all.

 

@bitnaut, Gotcha, thanks

 

Hi again everyone and thanks for all that you do for this community. I posted a few months ago about not being able to get an old HD 7970 running well. I've since upgraded to a new GPU - a Gigabyte 5500 XT. That did the trick and it worked well for a while, but something's changed - I think it might have been when updating from Mojave to Catalina. Now the system crashes whenever I plug the eGPU in - no matter if I first install the Purge Wrangler (manually, according to the Beginner's Guide) or not. If I leave the eGPU plugged in I get stuck in a boot loop - the system repeatedly crashes before reaching the login screen. 

I'm running an Akitio Thunder2 setup, with a 500W PSU. 

Gigabyte 5500 XT 8GB eGPU

Macbook Pro 15-inch, Mid 2015 with AMD Radeon R9 M370X 2 GB dGPU

MacOS 10.15.6

 

 

 

 

 

@oscar-j, backup your data, make a fresh install of Catalina, and then use purge wrangler. That should do the trick.  

 

@fredman, Thank you very much for your reply. I might try that if I'm really sure that'll work. However I'm in the middle of my thesis project and would rather not go through that process if I can avoid it right now. 

 

 

 

Hi everyone, 

for the first:

Thanks for the great instruction and software. This Page is a large help for my set up ideas. 

 

But, my Setup doesn't work. 

I have a Mac Book Pro 15 2015 with a Radeon R9 M390x (Big Sure 11.1) , a Razer Core X, and a Radeon R9 290x. Connectet with Thunderbolt 2 Cable and Original Apple Adapter.

 

With Windows 10 via Bootcamp no problem. 

In Big Sur i tried the Purge-Wrangler according to instructions. 
After reboot, with plugged cable, nothing.

If i plug the Thunderboltcable after reboot in the Macbook, the Screen is for a millisecond Black, after i see the Chip in the bar. If i grab the symbol < No external Card to Remove>. After 5 Seconds the Chip Symbol is disappeared. 

the following things i also tried: Amd Legacy Support Enable

                                               T82 Enable

                                               Reset Vram

                                               User Log Off

 

I couldn't find anything adequate in the forum. Yes i know the R9 290x is very old.... 

 

What can i do ? 
Whats my next steps to realize this setup? 

Is a functionality withe a Radeon RX 580 guaranteed? 

I hope for help, thanks 🙂 

Have a good Weekend 😀

Marc (sorry for my bad English)

going to make a clean install of big sur...I uninstalled through terminal both purge wrangler and purge nvda, should I enable SIP prior to installing big sur?
