TraumAmnesia Posted June 22, 2023 Share Posted June 22, 2023 (edited) Hi, there, I've been having this problem for 3 days now, so I think I need some personalized help. i9 13900K Asrock Z790 Taichi 128Gb Ram DDR5 RX 580 + RTX 4090 (Disabled on Mac via OpenCore tuto) I followed the OpenCore + https://www.reddit.com/r/hackintosh/comments/11xqvcx/success_macos_ventura_on_asrock_z790_taichi_with/ guide. Installation done, I'm on Mac, I can use it but I have to connect to HDMI on the motherboard to boot. My RX 580 is visible in the hardware info>Video cards/Monitor of the Mac preferences but if I try to boot on it with HDMI or DisplayPort on the RX 580 I get a boot block at this stage (see PJ "Error1" I also had "Error2" at one point). I'm also attaching my current EFI. Thank you very much!

Slice Posted June 22, 2023 Share Posted June 22, 2023 What is the vendor of the RX580? Link to comment https://www.insanelymac.com/forum/topic/357025-no-boot-when-connected-to-rx-580/#findComment-2807046 Share on other sites More sharing options...
TraumAmnesia Posted June 22, 2023 Author Share Posted June 22, 2023 Finally I succeeded! It's a Sapphire Pulse RX 580. All I had to do was change the ResizeAppleGpuBars from -1 to 0, and now I've got a hackintosh that's almost 100% functional! I'm waiting to receive my Fenvi t919 card. 40223 points on Geekbench, that's awesome! 2 Link to comment https://www.insanelymac.com/forum/topic/357025-no-boot-when-connected-to-rx-580/#findComment-2807093 Share on other sites More sharing options...
