Hello, here are almost all working setup of my NP530U3C-A02RU for MacOS Catalina 10.15.7 and latest for this moment OpenCore 0.9.3.
there are some little troubles with changing battery status when power cable is on or off. if someone can solve that problem, please give me solution.?
to get backlight control, you need to put kexts and framework from second archive to your /S/L/E and /S/L/PrivateFrameworks accordingly , than correct permissions and update kextcache. just google for that actions by urself.
