I did a ton of research before buying the Razer X Chroma and Radeon 6900 XT to make sure that both were compatible with macOS. Apple recommends the 6900 XT as a eGPU and Razer states that it’s compatible with the 6900 XT. I’m not tech savvy everything I find seems to make the connection look very simple. My iMac is a 8 Core 3.8GHz Intel 27” 5k with 128GB ram as seen in the pics. I’ve seen many people simply plug and play using their Macbook and screen so I’ve been attempting the same with my desktop since the external display is a “optional”
When plugging the Razer Chroma in, macOS does recognize that the unit is there under USB 3.1 Bus, and I can also see it under Thunderbolt/USB4. My current OS in Mac is Ventura 13.3 (pics attached). The GPU card is functioning, all fans spin on start up and the middle fan spins continuously afterwards. I’ve tried the Asix method with the most current drivers and it won’t connect. I’ve followed all of the troubleshooting methods as per Razer and have even gone to the extent of contacting Razer support (which was a waste of 2 hours).
I’ve bounced back and forth with Apple Bootcamp running Windows 10 and macOS. Windows 10 will recognize the 6900 XT but it gives me error “Code 12”. I know that Windows is recognizing the Razer unit because Synapse has full control over the Razer X Chroma in bootcamp, I can change all of the lighting display options manually. The 6900 XT is also showing up under Device Adapters.
I’ve spent roughly 20 hours this past week trying to get either one working. I’m about to downgrade macOS to Monterey and I’m also going to attempt to downgrade my Windows build version as a last resort. If anyone has experience with this or any helpful advice it would be much appreciated!
