Hi, I installed High Sierra quite difficultly on my L502x . and got the vanilla kexts , but my Graphics are not working properly.. I get heavy glitches and my system hangs while using Safari , for example if I minimize Safari it gets hanged and then I have to forcibly restart my laptop. Please guide me some easy way so I can work this out. I am using Clover v4297. I previously used a distro. But now I am using the High Sierra app downloaded from Mac Store.
