Thanks both — that makes sense, and I appreciate the clarification. I’m going to leave the EFI alone for tonight, as this is the first stable baseline I’ve had after several days of troubleshooting, so I want to be cautious about the next steps. I agree that <span>e1000=0</span> is probably...

Update: black screen / GPU handoff issue now appears to be resolved. I’ve now had five successful boots in a row, including two full cold starts and a restart from macOS. Current working boot args: -v keepsyms=1 debug=0x100 agdpmod=pikera alcid=11 npci=0x2000 dart=0 e1000=0<br> The main...

Thanks Edhawk. I don't have a real Mac but I do have two other hackintoshes — a Ryzen 5 2600X build that's been running the 6700 XT without any issues, and an X299 build that the 6900 XT has been running stably on for years. I'll try screen sharing from one of those. Thanks. Here's a full...

Thanks. To answer your questions: The BIOS situation was a reset to defaults — not a flash or version change. After the reset I reconfigured the settings for macOS. I'm not certain whether all the original settings were restored correctly, which may be relevant. To your specific questions: No...

Thanks Edhawk. To clarify — I have both cards available and I'm happy to use whichever gives the most stable build. My priority is stability. The card is a PowerColor Red Devil RX 6900 XT. Device ID is 0x73BF so it should be the standard XTX variant. No device-id spoof has been added. Current...

Thanks for the replies. The point about the GPU hanging off the chipset rather than connecting directly to the CPU is noted — two separate builds may ultimately be the right solution, and I'm keeping that option open. However, I'm currently trying to get the 6900 XT working in a single-GPU...

Goal I'm consolidating a separate Intel Hackintosh and Windows gaming PC into a single dual-boot workstation. macOS -> RX 6900 XT only Windows -> RTX 5090 + RX 6900 XT The RTX 5090 does not need to function in macOS. Ideally macOS would not even enumerate it. Hardware CPU: Ryzen 7 9800X3D...

Hi, I'm still struggling to get onboard Ethernet working. This is where I'm at. Onboard RTL8125 not enumerated at PCI level — X870E AORUS Elite / 9800X3D / Sonoma Hardware: Motherboard: Gigabyte X870E AORUS Elite WiFi7 CPU: AMD Ryzen 7 9800X3D GPU: XFX RX 570 4GB (temporary) macOS: Sonoma...

Ethernet not working — RTL8125 not visible to macOS Thanks for the input so far. Following on from my build thread, I'm having trouble getting ethernet working on my X870E AORUS Elite with 9800X3D running Sonoma. Hardware: Motherboard: Gigabyte X870E AORUS Elite WiFi7 CPU: AMD Ryzen 7...

Update — macOS Sonoma successfully installed! After a lot of troubleshooting I've managed to get macOS Sonoma installed and booting. Here's what fixed the various issues for anyone who finds this thread in future: Issue 1: EXITBS:START crashFixed by adjusting the Booter Quirks — specifically...

Thanks for the detailed information. I think I've added the EFI in my first post on Wednesday at 8.38pm GMT. Isn't it working for you? I'm away this weekend, but will resume efforts on Sunday, so any suggestions would be great.

Thanks for the responses so far. I wanted to update the thread as the plan has changed significantly. I've decided to abandon the eGPU approach after research suggested that USB4 eGPU on an AMD hackintosh is unreliable and largely unproven, particularly with the ASMedia USB4 controller on the...

Hi, I'm working with Claude to try to build this: CPU: AMD Ryzen 7 9800X3D Motherboard: Gigabyte X870E AORUS Elite WiFi7 (ATX, AM5) GPU (temporary): XFX RX 570 4GB — in primary PCIe x16 slot for build phase GPU1 (gaming): ZOTAC RTX 5090 SOLID 32GB — removed during build phase, needs SSDT to...
