Hello! I'm new to this forum so apologies if this isn't the right place to post this.


I've got a razer core V2, and I've just got my XFS RX 580 that I will be using with it.


Egpu works amazing on bootcamp, plug & play no problem.


Does not show up at all on macos (It powers on, but it's not detected and the GPU doesn't activate) have tried restarting, reinstalling, went through the troubleshooting guide this website has, no luck.


Can't figure it out. Would appreciate any help. Thank you


Edit: Should add that I am running MacOS Catalina 10.15.3, Official Release

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

While macOS is running, have you tried disconnecting and reconnecting the eGPU?
