Hi Family Olarila.
I have a problem for months I can not activate the Intel UHD Graphics 630, I already installed the High Sierra and the Mojave.
Both of them to no avail.
It can be just me that happens, but I already did everything that was tutorial to activate it and nothing.
I even managed to activate it in High Sierra but I did not check to use a restart day and did not load anymore.
I would ask for your humble help in solving this problem.
EFI link that ran in the High Sierra for some time, then did not work anymore.
