Administrators Hervé Posted December 31, 2022 Administrators Share Posted December 31, 2022 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.

CroJack Posted January 1, 2023 Author Share Posted January 1, 2023 Thanks for your reply Herve. I'll try my best and keep you guys posted about the progress Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 1, 2023 Moderators Share Posted January 1, 2023 PM961 indeed is supported. Assuming you have Intel Wifi / BT, give this a try. If it installs and works, post IOReg file using IORegistryExplorer.app v2.1 L570_OC_0.8.7.zip 1 Link to comment Share on other sites More sharing options...
CroJack Posted January 2, 2023 Author Share Posted January 2, 2023 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. Link to comment Share on other sites More sharing options...
CroJack Posted January 2, 2023 Author Share Posted January 2, 2023 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.

CroJack Posted January 3, 2023 Author Share Posted January 3, 2023 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.

Moderators Jake Lo Posted January 3, 2023 Moderators Share Posted January 3, 2023 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 Archive.zip 2 Link to comment Share on other sites More sharing options...
