Help! Literally half of the keys on the keyboard don’t work.. Just random ones :( I tried the SMC/PRAM reset but no luck. Booting in safe mode also doesn’t change anything.
Your post was sort of vague and I have a few questions for you before I can properly assist you. Has it been water damaged or spilled on at any point?Have you opened it before?Has it fallen recently?Was it working before?Are the non working keys in on particular area as opposed to random keys everywhere? It sounds like a hardware issue to me - meaning that either the keyboard is messed up internally and would need replacing, or that the cable connecting the keyboard to the motherboard came loose.
