Nothing here for this laptop afaik. You'll have to make one up, starting with basic usual settings for a regular Kaby Lake/HD620 laptop, then adding whatever may be required for your hardware accessories (LAN, WLAN/Bluetooth, audio, SD card reader, etc.).

 

Can't remember if Samsung PM961 SSD is supported, unlike its PM981/PM991 brothers which don't allow to install/run/boot macOS on them.

SATA Express? Wow, can't be many machines fitted with that.

It worked :) . I've installed Monterey on am external HDD because I don't have a compatible Wi-Fi card yet. The Intel one doesn't work. I'll run IORegistryExplorer tonight and post IOReg file here. Thanks a lot Jake Lo. :)

Wi-Fi (Intel dual band wireless ac 8265) is not working. I tried with itlwm.kext (for Monterey) and HeliPort.app, and removed Airportitlwm.kext, but no luck. HeliPort.app shows wireless networks and even that I am connected to my own network, but there isn't any real connection to the internet. Intel(R) Dual Band Wireless AC 8265 should be compatible with OpenIntelWireless, so I'm probably doing something wrong.

 

Brightness control doesn't work either.

UPDATE!!!

 

Wi-Fi works now.

 

Had to delete Ethernet port in SystemPreferences/Network and

 

com.apple.airport.preferences.plist

preferences.plist

NetworkInterfaces.plist

com.apple.network.identification.plist

 

in /Library/Preferences/SystemConfiguration

 

After reboot Wi-Fi started working. :)

Looks like I placed the wrong kernel limit for the AirportItlwm_Monterey.kext

Fixed that, added patch for SD card reader, fix Powermanagement.

Give this a try. replace Config and SSDT. Put AirportItlwm_Monterey.kext back in kexts folder

Post new IOReg file after the update
