Big Sur 11.4 | EFI folder for
OpenCore 0.7.1
Updates to the current version 11.4 of Big Sur have been smooth and hassle-free.
I attach the EFI folder for my hardware with Opencore 0.7.1 which, although it is still in beta, works very well and has improvements over previous versions. It has SMBIOS from iMac19.1. Serial numbers are not what I use.
Notes:
- The audio has layout-is 11 (alcid=11 in boot-args), you can change it to your liking
- There are 2 config.plists, one for use with the Radeon RX 580 dGPU (config-amd_as_main.plist) and one for use with the Intel 630 iGPU as a main or single card (config-intel_as_main.plist). Change the name of the one you are going to use to config.plist.
- Don't forget to rename the EFI-0.7.1 folder to EFI.
- I use CPUFriend + CPUFriendDataProvider kexts to set CPUPM to the CPU that is i9-9700, if you have another CPU delete these 2 kexts from config.plist or set them Enabled=False.
Note: it is an EFI for Z390 Aorus Elite boards although it may work well on similar boards but the USB port map (USBToolBox + UTBMap) only works for the USB port layout of this specific motherboard.
