I have a very strange problem with my gf MacBook Pro. After last big update on 22.12. my track pad is not working at all. I wasn't present when the update happened, but I was told that "everything worked fine, but after reboot, trackpad is not working at all". I tried to reset SMC, reset NVRAM, remove old OS and make a clean install, nothing works permanently. Only thing that works for like 20s from boot is SMC reset. Then the trackpad stops working again.
Data about the machine :
Current OS - High Sierra 10.13.2
Mac BookPro (Retina, 13 inch, mid 2014)
Model ID - MacBookPro11,1
Boot ROM - MBP111.0142.B00
SMC - 2.16f68
I am not Apple expert, so please if I am missing something you need, to troubleshoot, just tell me.
Thanks in advance.
