How to Install (Pt. 1 / BIOS Setting)

• Enter BIOS with F2 (hold F2 until you see BIOS)
  1. Enable Secret Settings (Ctrl + Alt + F7)
  2. BIOS - Main - Boot Features - CMS Support [NO] (IMPORTANT)
  3. BIOS - Advanced - Intel Advanced Menu - Power & Performance - CPU Power Management Control - CFG Lock [Disabled] (IMPORTANT)

How to Install (Pt. 2 / Make Bootable Disk)

• Download ghost image, if you're korean then go to x86.co.kr to get it!
• Check out https://medium.com/swlh/pc-laptop-create-a-hackintosh-usb-stick-e11a03ca371f if you don't have ghost image!
  1. Warning! Only follow part 2
  2. For Part 3, just download EFI files and replace old EFI with downloaded EFI

After install

• Some settings after you installed whole macOS, please follow this
  1. Settings - Trackpad - Turn off Force Click
  2. Download OpenCore Configurator
  3. OpenCore Configurator - Tools - Mount EFI
  4. Go to EFI volume and replace EFI w/ mine
  5. EFI Folder - OC Folder - open config.plist with OpenCore Configurator
  6. Go to PlatformInfo and generate serial number, other things and save & reboot!
     That's it!

AirDrop Dilemma

You have 2 options and one of these can enable AirDrop and another one can't (maybe, not confirmed)
First option: Get BCM94360CS2 with M.2 Adapter, attach on M.2 Slot (SSD) and sacrifice USB Port for BT and AirDrop
Second option (not confirmed): Get BCM94360CS2 with M.2 Adapter, attach on M.2 Slot (SSD) and just use Intel BT
