I used a bootpack from this tread to boot Mojave 10.14.3 on my SkayLake based Latitude 7480. Unfortunately I don't remember build version of Mojave. The trackpad did not worked until DarwinFix was applied in Clover config. I installed Mojave update version 18D109 later. After update I got Touchpad broken. After some time I removed DarvinFix and got the touchpad functionality back . So, to me the track pad issues (when VoodooI2C kext work for some peoples while it doesn't work for others) is also depends on OS build version and ACPI patches in clover. Now I wonder if you guys managed to get backlight adjustment work properly. I use AppleBacklightFixup.kext but the best I could get was 100% brightness, with a non-working slider :-(. Actually the backlight has 2 states depends on the slider position - Full brightness and no backlight at all. I have followed AppleBacklightFixup instructions down to the letter but no success. I done nothing but copy @catmater's config and got my backlight working very nicely, you should try that. Link to comment Share on other sites More sharing options...

Then i plug phones in jack, sound off (speaker) but no sound in phones. @Jake Lo, did you have any advise ? I have the same thing too. but something I found out is that when plugging the headphones the sound works for a split second and then cuts off. if that helps anyway Link to comment Share on other sites More sharing options...

I can't just use his config. His Latitude has KabyLake processor and hence HD620 graphic card while mine 7480 has SkayLake processor with HD520 graphics. By the way, I have checked my earphones output. It doesn't work as well. I didn't paid attention earlier cause I don't use it often. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted February 26, 2019 Moderators Share Posted February 26, 2019 The release version also has layout-id 21, so should work too. https://github.com/acidanthera/AppleALC/releases 2 Link to comment Share on other sites More sharing options...

As for backlight brightness control, just noticed that backlight control + AppleBacklightFixup.kext works after sleep. I guess I need to read carefully discussion at tonycrapx86 forum to troubleshoot it. Link to comment Share on other sites More sharing options...

catmater Posted February 26, 2019 Share Posted February 26, 2019 Cant understand. Touchpad work fine, but only some two-finger gestures work. Link to comment Share on other sites More sharing options...
Nancy10 Posted February 26, 2019 Author Share Posted February 26, 2019 Why only the 2 finger gestures? I meant is there no fix for it or does the touchpad itself (hardware) not support more than 2 fingers ? Link to comment Share on other sites More sharing options...
