[sonoma|OC|v1.8.1|TM1701]iMessage/FaceTime only works with USB ethernet dongle

[bamdadkhan]

Pre-requirement

• For macOS version < Big Sur, try to rebuild the kextcache (e.g. run sudo kextcache -i / in Terminal.app) and restart whenever you encounter a problem. It always works like a charm!
• If you are using OpenCore, also try to reset NVRAM. Press Space key when you are in OpenCore boot page and choose Reset NVRAM.
  DONE

State the model

• XiaoMi-Pro MX150, TM1701

State the version of the EFI

• v1.8.1

Describe the bug

• After creating a (seemingly) flawless SMBIOS and injecting it into config.plist, then adding https://github.com/OpenIntelWireless/itlwm/releases/download/v2.3.0-alpha/AirportItlwm-Sonoma-v2.3.0-DEBUG-alpha-ff1138b.zip to fix wifi, iCloud login started to work with System Settings, App Store etc.
• However, iMessage and Facetime only connect (or log in) when an USB Ethernet dongle is connected. Messages get 'sent' when it's in, when disconnected, they get 'not delivered'.

System log

• N/A

Screenshots

Attach your entire EFI folder

• Please attach your entire EFI folder to help solve your problem.
• Erasing serial numbers in config.plist is required!
  EFI.zip

Attach system.log

• If applicable, please run log show --predicate "processID == 0" --last boot --debug | grep "ERR" in Terminal.app to help locate the problem.
• N/A AFAIK

UPDATE: Seems to be an issue with the beta 5 AirportItlwm.kext for Sonoma: OpenIntelWireless/itlwm#923

Possible workaround for now until itwlm kext is fixed.
