2011 MacBook Pro Mac OS X high Sierra, made all security and system updates.
One morning (no spills no drop) my trackpad was unresponsive the keys were mostly unresponsive, I’d hit them like 5 times and maybe get a letter to type. A few minutes later, nothing didn’t work again.
External keyboard and mouse work.
Tried smc, PRAM, tried going into safe modes, tried restarting via disk mode, safe modes, replaced the trackpad, ran an extensive hardware test with it claiming no issues with hardware, cleaned out the inside of the laptop.
Areas of concern: When I go to system preferences -> trackpad it says no trackpad found.
Hardware test in internet recovery mode said no errors (control d) (D on startup) hardware test said initializationfailed: unable to run diagnostics. DEC500 try running applediagnostics again. If the issue persists contact Apple support.
So I’m at wits end on what to do and wasn’t sure if there are other options I could use to fix the software so this works again.
Thank you for ANY suggestions and a super thank you to anyone who can find a solution to this pain of a problem.
