CroJack Posted January 3, 2023 Author Share Posted January 3, 2023 Yes, I replaced the SSDT. May I ask where did you place the wrong kernel limit for the AirportItlwm_Monterey.kext? SSDT or config.plist? And why is it important to place kernel limit? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 3, 2023 Moderators Share Posted January 3, 2023 it's in the config file for the kext. Reason for the limit is to prevent it to load for any other MacOS other than Monterey. There's a difference version for different MacOS. Ok. I'll check the SSDT again to see why PM and PNLF is not working. Try replacing with this SSDT Post new IOReg file SSDT-L570.aml.zip 1 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted January 4, 2023 Moderators Share Posted January 4, 2023 Looks like Powermanagement is working too. Are the brightness control Fn keys working too? Sleep / Wake with lid open and close? HDMI / HDMI Audio? Link to comment Share on other sites More sharing options...
CroJack Posted January 5, 2023 Author Share Posted January 5, 2023 - Are the brightness control Fn keys working too? Yes - Sleep / Wake with lid open and close? Yes - HDMI / HDMI Audio? Can't tell. I don't have a miniDP to HDMI cable. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 5, 2023 Moderators Share Posted January 5, 2023 Oh, so the laptop has a miniDP connector, no HDMI? if you want to use the rest of the Fn keys, see my T14 gen1 guide on my signature.
