Sonoma 14.4 + OC 0.9.9 working on my NUC817BEH. Attaching the OC bundle in case its useful to anyone.
Couple of changes that folks using this need to be aware of:
AirportItlwm.kext
Using the latest dev build for Sonoma 14.4. If you want to use this EFI with lesser macOS versions then change this as necessary.
IntelMausiEthernet.kext
Upgraded this to the latest
branched version (2.5.4) to solve kernel panics after sleep/wake
IntelBluetoothFirmware.kext
IntelBTPatcher.kext
Uses
this branched version of 2.5.0 to support pairing of BT LE devices such as mice and keyboards.
SSDT-GPRW.aml + Patch
After solving aforementioned issues with BT LE devices pairing, this fixes a sleep/wake issue when those BT devices are connected where the system
wakes several seconds after each sleep.
However, the downside is you need to wake the system using the NUC power button, so if you don't need to pair any BT LE devices you may want to leave out this SSDT+patch.
