dazzlersa Posted June 14, 2021 Share Posted June 14, 2021 Hi All I accidently messed up my USB stick with my Big Sur EFI Boot config. I have re-done everything but it seems it might be having an issue trying to get it to boot because it was in sleep or hibernation mode. I am running: i5 8500 Coffee Lake Asus Z370 AMD XT5500 Attached is the error screenshot and my config.plist Any help would be GREATLY appreciated as this is my DEV machine at home. TIA Daz config.plist Quote Link to comment Share on other sites More sharing options...
etorix Posted June 14, 2021 Share Posted June 14, 2021 Have you remade it from your notes or from the standard guide? Upon seeing a panic with register CR2, I'd try the EnableWriteUnprotector quirk. Clear NVRAM and reboot. Quote Link to comment Share on other sites More sharing options...

Oh My Hat, you are almost a LEGEND!!!! hahaha. It booted through all the text but then to a black screen and can't do anything from there. Anything else you think I need to change now? I didnt have notes (something i will make sure i backup this time, lol) so just from standard quide. Not sure how to clear NVRAM, do you mean reset it in the boot menu?

I tried resetting, same problem, monitor just goes into sleep mode. Anything else you can recommend? I am assuming something to do with my dGPU (XT 5500)???? opencore-2021-06-18-174852.txt Quote Link to comment Share on other sites More sharing options...
etorix Posted June 19, 2021 Share Posted June 19, 2021 (edited) As far as I can tell, OpenCore works fine; the issue is within OS X. So with EnableWriteUnprotector, you go through verbose boot with no kernel panic but end in a black screen. Do you use bootarg "agdpmod=pikera" with your RT 5500XT? Spoiler Navi 10 Series # Highest Supported OS: Current/Big Sur(11) # Initial Supported OS: Catalina(10.15) Currently, as of 10.15.1, Apple has finally added RDNA and Navi support! Supported Cards: RX 5500 RX 5500 XT RX 5600 RX 5600 XT RX 5700 RX 5700 XT RX 5700 XT 50th Anniversary Edition Radeon Pro: Radeon Pro W5500 Radeon Pro W5700 Note: Most Navi cards currently require the boot argument agdpmod=pikera to get proper display out, also keep in mind DisplayPort can be a hit or miss as WhateverGreen needs to be adapted.

dazzlersa Posted June 19, 2021 Author Share Posted June 19, 2021 D00d!!!! You ARE a LEGEND! All good and back up and running. Time to back up all settings and try figure out how to boot up without the USB stick. 1 Quote Link to comment Share on other sites More sharing options...
etorix Posted June 19, 2021 Share Posted June 19, 2021 Glad to know it worked. (Please feel free to use the Like/Thanks button.) For the possible sake of other users, it was EnableWriteUnprotector + agdpmod=pikera, right? Copy the EFI boot folder to an OS X partition, if it's not already done. Unmount USB EFI partition, mount your HDD/SSD EFI partition (do not have two EFI partitions mounted at the same time, it's confusing for you and for OS X). Copy EFI folder to EFI partition. You may still want to do some post-install tweaks (OpenCanopy, USB mapping, audio mapping, etc.) before you're completely done. Then, keep the USB stick in a safe place. 1 Quote Link to comment Share on other sites More sharing options...
