To Do

• Automatically update OpenCorePkg and Kexts by a script
• Automatically generate update info and update ReadMe
• Automatically update repo weekly by CI

Note

1. For macOS 12 Monterey, DW1820 do not work well (can not use Airdrop, Handoff and Sidercar). Therefore I change it to BCM94360Z4 and it works well!
2. Monterey 12.3 and iPad OS 15.4 start to support Universal Control (also need BoardCom wireless card), works for me.
3. Strongly recommand you to re-create USBMap.kext for your own laptop with this tool.
4. If you change your hardware (like wireless), re-create the USBMap.kext as well.
5. It is strong recommanded that re-generate a serial number for your own laptop (needed to be check invaluable in apple.com) !
6. Do not turn on Find my mac!
