Updated from macOS 13.2.1 to 14.4 successfully, OC 0.9.9 Set SecureBootModel do Disabled during install (did not even try to leave it to Default considered all comments here), then back to Default without any fuss.

After some worries to migrate from Clover to OpenCore on Catalina (Clover to Opencore on GA-Z370 HD3P + UHD 630: no macOS partition), I went through the update to Big Sur like a breeze just by downloading the installer from the App Store and installing like a real mac. Nice! NB: I'm currently...

I finally applied your recipe: 1. Booted on OC from USB drive. 2. Selected Install macOS Catalina, accepting to lose my Clover backups when the system asked me to. 3. Waited 20 minutes, then the machine rebooted, picked boot from USB, and I selected macOS Installer from the OC picker. 4...

Glad you make it. As for me, opencore is not very friendly... OC browses all the partitions to find .efi it knows about. This is why you see \System\Library\CoreServices\boot.efi or \EFI\Microsoft\Boot\bootmgfw.efi are missing in my log. This is normal to me. But \EFI\BOOT\BOOTX64.EFI is found...

Thanks. Changed HideVerbose to false, rebooted, reset NVRAM, and got this log file. Not sure what to think out of it.

Thanks for your answer. I turned all the points that were yellow into green, and changed XhciPortLimit to false since USB mapping has been done, but unfortunately still the same issue: OpenCore v0.6.3 Intel Coffee Lake Sanity Check

Hello I'm currently using Clover + Catalina 10.15.7 successfully, but I wish to swap Clover for Opencore before upgrading to Big Sur. The thing is, I've spent hours trying to do it carefully following https://dortania.github.io/OpenCore-Install-Guide/ but no luck so far. Basically, in order to...

Wow! Great finding. Works perfect for me too. Thanks.

Unfortunately, I now have a problem to wake up my screen on HDMI after sleep since 10.15.4. I can see I'm not the only one, but no proper solution yet: Screen sleep stopped working after update to mac os Catalina 10.15.4 Was working good yet with 10.15.3.

No, but I use the -disablegfxfirmware boot flag like advised by @tonymacx86 on page 1.

Yes, I always reboot first before upgrading MacOS after updating Clover.

Updated Clover Configurator to latest version so that it can find Clover v5107. Updated Clover from v5103 to v5107 Updated AppleALC / Lilu / WhateverGreen to latest version Installed MacOS 10.15.4 after a few reboots Et voila

Just gave it a try, but no luck with iMac 18,1: not starting, like iMac 17,1. I'll stick to 14,2. Thanks anyway.

Gosh, 10.14.1 got me a hard time! It installed OK but then, it just got stuck with no error message, with no crash or whatsoever, just not willing to start the GUI. I even restored my previous 10.14 conf. from Time Machine backup 3 times, before I thought about changing the SMBIOS Product Model...

Hi, In case this may be helpful to s.o else, I solved my problem by replacing Mac Pro 3,1 with iMac 13,1 in the System definitions of MultiBeast 6. Now, EIST is enabled again in the BIOS, and Mavericks boots happily :) Cheers

Hello, Here is my conf.: Asus P8Z68V LX + Intel Core i5 2500K + RAM Patriot PC3-12800 1600MHz 8GB (2x4GB) + nVidia GT240 512MB GDDR5 I used to have a perfectly working system on 10.8.5, no DSDT, but since Mavericks update (Unibeast method), I cannot start with EIST enabled in the BIOS...

Hello, I posted at the wrong place, sorry for that. Don't know how to remove it. Can a modo destroy the thread? Thanks!
