I am looking for information / help from someone who might experienced similar issue in the past or has knowledge about the problem described below.
During last week I have been experiencing issues with trackpad on MacBook Pro Retina 13' Mid 2014.
It all have started the next day after latest macOS Sierra 10.12.3 update.
- not registering multitouch commands, like thumb + 3 or 4 fingers, swipes
- freezes on the movement just to pick up a second later
- stops to respond at all
- moves and send click signals by itself without touching
Some/all of this happen when I try to use trackpad. When left alone, with external usb mouse plugged in, I can use the software mouse without any issue (using external mouse).
I have tried to fix it with:
- NVRAM reset
- SMC reset
- macOS reinstallation
sadly, none of above helped.
Valuable Info: Apple Diagnostics tool shows that I have problem with memory (PPM002 error code and potential PPM003 and PPM004). Apple code reference page says nothing more about them but to contact nearest Apple Authorized Service Provider.
I will appreciate any form of help.
And yes... My warranty expired just two weeks ago.
