Ok I did the steps mentioned, the brightness keys do work, according to Intel power gadget the CPU frequency does change when I shift workload, I was able to reboot a couple times without any issues with the config.plist you sent me, but this morning it gave me a Kernal panic saying"error loading Kernal cache (0xe)" so I started to enable different options individually in clover bootloader and it only booted when I enabled Kernal xcpm in clover, do you know why this is happening?
