Trackpad totally dead, any ideas why.
I've got a A1398, MacBook Pro 15" 2.2 GHz Core i7 - Mid 2014 system with 2 issues: a bad battery and a totally disabled trackpad.
I've tried all possible troubleshooting and diagnosing I could with no luck.
I ordered battery and new trackpad and swapped them both, but the trackpad still not working.
All the settings inside the computer checked. In the end, I took a backup and re-installed the OS, but the problem remains!
Can anybody help me with this issue?
Is this a good question?
