I have to press hard on it to make it function.

You do not say what exact Mac...

Sounds like a hardware fault

Oh, it's a mid 2014 15" Macbook Pro.

Thank you

The 2014MBP had some known issues with long term trackpad use, The 2015 MBP was the worst in this regard.

Typically a new cable is all that is required. These connections are easy damaged...

any computer repair shop that works on Mac can diagnosis, estimate a cost and do the repair— if you decide to go forward with this computer.

I have a macbook pro. Maybe I'm using the wrong term; it's the trackpad built in the laptop.

There are 57 different MacBook Pro models since 2006....

as you might imagine they are not all the same,
