I have followed all the instructions provided at MacBook Pro: How to disable discrete GPU permanently from EFI?
My question is:
Is it safe to update my macOS to latest High Sierra or even to Mojave (Recently I have High Sierra 10.13.1) or it will erase all my kext settings and make my broken GPU appear again? And do I have to do all the process all over again from the beginning, which I would like highly to avoid.
Sorry if this question been asked before, since i cant find this question somewhere else.
