orbita Posted February 28, 2023 Share Posted February 28, 2023 (edited) Hi. I had a happy high sierra install for the last few years. I finally need to upgrade it so just purchased a Sapphire RX580 to replace geforce 980ti. The rest of machine is intel 9900K on Gigabyte z390 aorus pro, Samung Evo 970 ssd. I have tried Clover and Opencore - neither working (1) Clover - Booting but no screen I eventually managed to get the high sierra to install after various attempts at upgrading clover and the kexts. It now boots with clover 5119 but the monitors do not work. I have tried DP and HDMI ports. Various settings (enable disable igpu), radeon boot flag, setting number of ports to 5. I can however access the machine via screenshare from another laptop this way. (2) Opencore - Panic during boot. I have followed the opencore process and have an EFI that now that starts to boot but panics. I attach a screenshot showing where it stops. Couple of things I notice are the lines - Refusing new kext as.vig9696.Lilu, v1.6.3 already have prelinked v1.2.1. - NvidiaGraphicsFixup: init @ failed to call parent 7 It seems to have an old Lilu registered but I don't know why that is? I also don't have nvidiaGraphicsFixup in the OpenCore EFI so why is that appearing? I wondered if it was in my /Library/Extensions but I've now removed all nvidia kexts from there and run disk repair. I've also added the nvramreset efi and selected that at boot. ------ In both cases I'm using imac 19,1 Appreciate any suggestions that might make either of them work. Thanks!

aniuks27 Posted February 28, 2023 Share Posted February 28, 2023 (edited) Can you share your EFI? and why Catalina? P.S. It's always better to do a fresh install Edited February 28, 2023 by aniuks27 Link to comment https://www.insanelymac.com/forum/topic/355849-struggling-to-get-hs-catalina-upgrade-working-on-clover-or-opencore-9900k-z390-rx580/#findComment-2801886 Share on other sites More sharing options...
orbita Posted February 28, 2023 Author Share Posted February 28, 2023 ok I've actually got it to boot after rebuilding kext-cache. I now have 2 issues. 1) I have no network and if I add intelmausi.kext it won't boot. Screen goes black just before apple log appears. 2) It doesnt shutdown - it just hangs. I choose Catalina because I couldnt upgrade to BigSur or Monterey. The installer refuses to install. Once I get this going maybe I can look at upgrading later. I'd rather not reinstall from scratch as I have many installed music software and plugins that will take a long time to setup again. EFI attached (without intelmausi) Thanks!

orbita Posted February 28, 2023 Author Share Posted February 28, 2023 I've noticed that the Monterey and BigSur installers run now that I can boot into catalina - so maybe I could update before continuing. Just concerned I don't have network yet..

orbita Posted February 28, 2023 Author Share Posted February 28, 2023 So after it went black again trying the intelmausi kext, I left it and was reading another webpage. Suddenly it came to life and I could log in and internet works. It still doesn't shutdown though.. and after forcing a shutdown, it takes a couple of minutes to startup again - maybe due to not shutting down properly?What do you think could be causing this?
