Supervisor fabiosun Posted February 21, 2021 Supervisor Share Posted February 21, 2021 do you mean you have yet installed it or you see many verbose errors? It could be a very long process to install this beta ..many verbose errors I see also many patches our chipset does not need ..(ie Fix Pat related ones) 1 Link to comment Share on other sites More sharing options...

Supervisor fabiosun Posted February 21, 2021 Supervisor Share Posted February 21, 2021 (edited) @ddk try this EFi and see if you have the same problem... or different one EFI.zip sometimes some quirks could create problem..but not usb related for now...memory map related one.. let me know first you must be sure you have installed it well because also in real MC installation was problematic in beta 2 (d version) change in this EFI only mmio part..insert yours Edited February 21, 2021 by fabiosun change in this EFI only mmio part..insert yours 1 Link to comment Share on other sites More sharing options...

ddk Posted February 22, 2021 Author Share Posted February 22, 2021 I had to apply AMD_Vanilla patch to avoid kernel panic result: same issue I think AMD_Vanilla patch should make a new patch for Zenith II MB. Link to comment Share on other sites More sharing options...
Supervisor fabiosun Posted February 22, 2021 Supervisor Share Posted February 22, 2021 (edited) I do not think is a patches problem but I am not sure of this maybe it is an EC device problem..

ddk Posted March 1, 2021 Author Share Posted March 1, 2021 Tomorrow I will receive "Sonnet eGPU Breakaway Puck Radeon RX 5700" Is there any special setup in opencore except for bootArguments agdpmod=pikera and disabling Internal GPU RX 6900 XT ? Is the EGPU may solve my booting problem on 11.3 beta ? Link to comment Share on other sites More sharing options...
Supervisor fabiosun Posted March 2, 2021 Supervisor Share Posted March 2, 2021 If I am not wrong it is a thunderbolt external GPU case... if you have a well configured thunderbolt rig...it could work easily! 1 Link to comment Share on other sites More sharing options...
