Apple MacBook (12") trackpad is going haywire

[juan99999]

After about a month of non-use, (stored in a drawer with nothing on top) I booted my MacBook today and the trackpad has become way sensitive. I can't scroll across the screen without it triggering 20 clicks (and messing up my desktop). If I press (hard) and keep it pressed, I can scroll fine...

I've tried resetting SMB, NVRAM, issue persists.

Only way I can use my mac is via a bluetooth mouse!

Is there anyway to calibrate the trackpad? I've set press sensitivity to the least sensitive and tried messing with some of the accessibility options, but it's still way too sensitive.

What model is it? The battery should be checked for swelling, perhaps. I haven't personally seen this type of behavior but that's the first thing that popped into my head.

It's a 2015 12" retina MacBook. It has a haptic (non mechanical) trackpad...
