      Installing macOS Big Sur 11.0 DP1 on Gigabyte Z370N WIFI + i7 8700K + UHD 630

      06/28/2020 22:05h GMT-0
      - Replaced detach command when creating ISO.
      - Thanks @ham4ever 
      - Added instruction to run one line at time.
      06/27/2020 02:37h GMT-0
      - iMessage works too. Just not at first boot.
      06/26/2020 18:54h GMT-0
      - First version.
      What works and what does not
      - Processor: Intel Core i7-8700K ->  Work. All SpeedStep stages.
      - Video Card: Intel UHD 630 ->  Work. QE/CI and Metal.
      - Chipset: Intel Z370 ->  Work.
      - HDMI 2.0 (1st) ->  Work.
      - HDMI (2nd) ->  Work.
      - DP ->  Work.
      - Audio: ALC1220 ->  Work.

      - USB3.0 ->  Work.
      - Sleep ->  Work.
      - Airdrop, Handoff, Instant Hotspot and Continuity ->  Work after replaced wireless.
      - Fix iMessage (other iServices works perfectly)
      - Nothing
      Bootloaders are currently unable to start the installation.
      The solution is to use a virtual machine and use a physical disk (additional, USB or SATA, NVME) as a target in the installation.
      Change the OpenCore compiled from the source code, and add some entries in NVRAM through config.plist.
      This is not the best solution. But it is the only way at the moment. There are some ready-made images available out there, but I prefer not to use them and create a clean installation.
      What you need to install
      - Running install of macOS
      - Already working OpenCore with this setup
      - Create bootable ISO file
      - Spare Disk/SSD
      - macOS Big Sur DP1 install app
      - Latest OpenCore + Kexts compiled from sources
      - Some KEXTs and SSDT patches
      UEFI configuration
      My BIOS is F10 (I use an 8th generation processor, so I don't need to upgrade)
      You can configure manually or load my BIOS profile.
      - Shutdown and insert the flash.
      - Power on with DEL pressed to enter BIOS setup.
      - Change value: BIOS - CSM Support to Disabled
      - Change value: BIOS - Secure Boot to Disabled
      - Change value: Peripherals - Initial Display to IGP
      - Change value: Chipset - VT-d to DISABLE
      - Change value: Chipset - Internal Graphics to ENABLE
      - Save & Exit Setup
      or, BIOS profile
      You can use one of my BIOS profiles attached bellow.
      It's two versions. One stock and another with overclock [5.0 GHz]
      - Put the profile in the root of the flash drive at EFI partition.
      - Restart with DEL pressed to enter BIOS setup.
      - Go to Save & Exit.
      - Select Load Profiles.
      - Select last option and then the flasdrive in the list.
      - And finally choose MACOS_STOCK or MACOS_5GHZ.
      - Save & Exit Setup

      How create bootable ISO file
      Download Big Sur DP1
      Run this command on Temrinal:
      sudo /System/Library/PrivateFrameworks/Seeding.framework/Resources/seedutil enroll DeveloperSeed Go to System Updater and download the Install macOS Beta app.
      Create ISO
      Then run on Terminal (One line at a time):
      hdiutil create -size 12G -fs hfs+ -volname install -type SPARSEBUNDLE ~/Desktop/install hdiutil attach ~/Desktop/install.sparsebundle sudo /Applications/Install\ macOS\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/install --nointeraction hdiutil detach `diskutil list |grep 'Install macOS Beta' |awk '{print $8}'` -force hdiutil makehybrid -o ~/Desktop/install ~/Desktop/install.sparsebundle rm -rf ~/Desktop/install.sparsebundle
      Now you have install.iso on desktop.
      How create create the virtual machine and install to disk/SSD
      Download and install the trial version of the VMware Fusion from their site. I'm used the version 11.5.5.
      - Create a custom virtual machine

      - Operating System: Apple OS X - macOS 10.15

      - Create a new virtual disk (The size doesn't matter, We'll delete later)

      - Click in "Customize Settings"

      - Save the VM on desktop with name: bigsur

      - Insert the spare disk/SSD on PC (reboot if necessary) and identify what /dev/diskX is.
      You can look on Disk Utility.app:

      - Create VMDK that point to it:
      sudo diskutil unmountDisk diskX /Applications/VMware\ Fusion.app/Contents/Library/vmware-rawdiskCreator create /dev/diskX fullDevice ~/Desktop/bigsur.vmwarevm/physical sata - Edit the virtual machine settings created previously

      - Click in Hard Disk (SATA) and delete it (Remove Hard Disk)

      - Then add the physical disk

      - There's a bug in Fusion. To select the physical.vmdk, right click then "Quick Look", then "Share virtual disk with the virtual machine that created it"

      - Click Apply.

      - Now mount de install.iso

      - Start the VM and install as usual until: Disk Utility, format GUID with APFS (VMware Virtual SATA Hard Drive Media), Install macOS, wait few reboots and stop at first boot wizard.
      This can take up to 45 minutes. It may seem like it is stopped, but it is not.

      - Press Command + Q and shutdown (usually WIN + Q)

      - Close VMware Fusion.
      Copy OpenCore to EFI
      - Mount the EFI with:
      sudo diskutil mount diskXs1  
      - Copy your current working OpenCore EFI to that mounted EFI.
      - Download mine attached or Update your OpenCore, Kexts and driver UEFI.
              - You can use the @MaLd0n script attached to compile all (OlarilaOC.command.zip)
              - If using mine add your MLB, ROM, SystemUUID and SystemSerialNumber. (see how to)
      - Add following items do config.plist:
      NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> boot-args -> -lilubetaall (append)
      NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> booter-fileset-basesystem + Data + <00>
      NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> booter-fileset-kernel + Data + <00>
      NVRAM -> Delete -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> booter-fileset-basesystem
      NVRAM -> Delete -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> booter-fileset-kernel

      Boot from the new disk/SSD and finish de first boot wizard.
      And last but not least

      After hearing that OpenCore is so much better than Clover, and that it will probably be able to boot Big Sur before Clover does, I decided to take the jump.
      Running Catalina 10.15.5 18F101 with OC 0.5.9.
      So far I like the result. The OS feels faster, boots faster.
      And absolutely everything works (sleep, network, etc...)
      So, that's it? Is there anything else I have to do?
