ok well I remember for me not many things worked but keyboard, lan, and other few things after I've made my own post install with clover configurator, then I 've found RehabMAn's config.plist repo and this is where I got mine which has quite everything working now. I took the one I'm using by choosing in his list : kabylake+ intel HD620 .
Now I've got battery status, full graphics, sound, backlight etc...
You should give it a try
