Hi RehabMan, been doing this for awhile lol, I got this laptop working perfectly under High Sierra 10.13.6. Now I'm just stuck on this brightness issue under Mojave 10.14.4. Any help is appreciated. Thank you.

Followed this guide: https://www.tonymacx86.com/threads/...ontrol-using-applebacklightfixup-kext.218222/

Have brightness slider in System Preferences>Displays
Fn+F11 and Fn+F12 activates brightness UI popup

Only issue is no actual brightness adjustment. Either it can be at the brightest setting or the lowest setting. When booting to clover, I am able to adjust using the the F11+F12 without Fn to adjust brightness before booting to macOS.
