Administrators Hervé Posted October 1, 2022 Administrators Share Posted October 1, 2022 -> moving to correct Latitude 7xxx forum section. Plenty of thread/topics and available Clover or OpenCore bootlicks (EFI folders) for Kaby Lake Latitude 7280 on the forum. Please use the forum search facility and try and post in the correct sections. 1 Link to comment Share on other sites More sharing options...

Administrators Hervé Posted October 1, 2022 Administrators Share Posted October 1, 2022 There's nothing specific about KBL HD620 graphics as far as 1920x1080 and Monterey are concerned. The graphics settings remain the same whatever the macOS version. Link to comment Share on other sites More sharing options...

Baio77 Posted October 2, 2022 Share Posted October 2, 2022 Test this : -igfxblr boot argument (and enable-backlight-registers-fix property) to fix backlight registers on KBL, CFL and ICL platforms.

Administrators Hervé Posted October 3, 2022 Administrators Share Posted October 3, 2022 PNLF section of your all-inclusive SSDT looks a bit short to me... I invite you to compare with the more "regular/usual" SSDT-PNLF recommended/available for KBL platforms. https://dortania.github.io/OpenCore-Install-Guide/config-laptop.plist/kaby-lake.html https://dortania.github.io/Getting-Started-With-ACPI/ssdt-methods/ssdt-prebuilt.html#laptop-skylake-and-kaby-lake https://github.com/dortania/Getting-Started-With-ACPI/blob/master/extra-files/compiled/SSDT-PNLF.aml Link to comment Share on other sites More sharing options...
