POST
  • run sudo pmset -a hibernatemode 0
  • If on 3K disable sleep completely for maximum stability
  • If no mouse, install all voodoo kexts using Kext Utility
Description
  • This esentially an ultra-simplistic version that is stable without the use of a deploy or complicated file installations and copies.
  • You can easily view all the SSDT patches along with configuration files for the bootloader as they are all documented clearly in the files.
  • This does include a copy of Clover, which of course I do not contribute to and am only responsible for the provided files, patches, and kext placements
This guide provides a working setup with little knowledge of the topic and without "optimization" (because often they can break things). But, it is fully functional and preforms properly and is stable
  • Make sure you are using DW1560 for wifi or else KP. If not using remove BRCM kexts from CLOVER>kexts>other.
BIOS Setup
  • Set all SATA operation as AHCI
  • Disable Secure Boot, Fast Boot
  • For Coil Whine improvement disable C-States
  • Enable UEFI Booting
INSTALL (VERY IMPORTANT)
  • Due to structural changes in the setup of apple's Big sur, this EFI cannot boot the installer it can only boot into a system / device that has already been created and setup.
  • To do this, you need to install Big Sur to a virtual machine (lots of guides online) and then create an dmg of that system, and restore it onto your HDD using the 'dd' command
  • There are various guides online how to get this virtual machine setup complete.
  • You can then use the attached EFI folder to boot and use macOS big Sur
  • You can use this video to show you how to get your macOS pre-installed onto your hard drive

Boot Entry Setup
  • Boot into the BIOS of the computer, then navigate to the Boot setup (or entries (not sure what it is called exactly, but it will be a list of the options your computer selects to boot)
  • Click add new, and make sure the USB isn't plugged in.
  • Select the only option that is avaiable, and in FS0 navigate to Boot/BOOTx64. Add this as an entry, then select this as whatever priority you would like.
Messages and Facetime
  • Gnerate your own Serials, Board Numbers, MLB
  • There are various guides online to do this and as default they're set to essentially Null (Fakeserial)
  • This is fairly straightforward and there is lots of external recourses, or you can contact me for support.
Headphones and Audio
  • All audio from speakers should work perfectly along with Bluetooth and USB audio
  • To resolve headphones static issue (wired) install combojack
Finished!
  • Congratulations, there really aren't any more steps that are required. Feel free to contact me with any questions.
