From yesterday my trackpad has been behaving weirdly, the mouse pointer is stuck and does not function. Are there any instructions on how to debug or replace the trackpad? Looking for some guidance on it. Update (02/24/2019)
The battery covers the trackpad sadly so you need to take it out to even get to the adjustment screw or to replace it. Here’s the guide you’ll need to follow: Battery and Trackpad. Disassembling MacBook Pro 15" Retina 2012-2015
