Answer to: Internal keyboard and trackpad not workingHi, I'm not entirely sure if this will work but please give it a go because I'm posting this right after I managed to find the fix (hopefully a permanent one): 1. Shut down your MBP 2. Connect an external keyboard to your MBP 3. Reboot your MBP while holding the Shift key to go into Safe Boot 4. For me, my trackpad and keyboard instantly revived, and I just shut the MBP down and switched it on normally. It took me ages to try this because all I could find were suggestions to reset SMC and PRAM. I even did a clean wipe of my MBP, nothing worked. I'm just posting this in hopes that it helps, but I'm praying hard that this is a permanent fix for me as well.
