Process status

• Installable

  Use this EFI you can successfully finish installation and enter system UI interface, all things are fine but ethernet are not working , a part of usb ports cannot be use, and never been wake up from sleep status by interaction from mouse or keyboard.

• Usable

  Use this EFI you can use ethernet by certain configs, all USB ports work properly.

  

  Wake-able

  Custom the SSDT-EC.aml file to speed up boot, remove all unnecessary boot-args, set layout-id id (ALC1200) in config.plist, boot-args field value to igfxonln=1 so your Monterey can wake up with monitor display. A weird issue is Ethernet cannot be change to 1000M or 2500M that's really disappoint me cause realtek8125 kext never been update since April 30 in this year.
