Dell latitude 5480: Big Sur installing - EFI folder required
Alex Kranich replied to Alex Kranich's topic in The Archive
Now keyboard is working, but touchpad mouse and wifi are not working, i am keeping Catalina OS and updated all with opencore i dont know why but if i install updates, and this mean install big sur latest version, i get error panic. Instead of this, if i dont update kexts in opencore , updating only kext for keyboard . I install big sur as update and in this case boots and i have keyboard and wifi working. but still mouse and touchpad no. I seen that with big sur i have some lag and notebook is not reactive like with catalina. -
