Retina Macbook - Jumpy / erratic cursor

[scarecrow81]

I too have experienced this issue on the new macbook and I am convinced it is my thumb causing the issue. I have found while sitting at a desk, raising the back of the macbook about and inch and a half forces me to change hand position while typing and the issue disappears. Yes, disabling tap to click takes care of it too, but one hates to give that up.

I made a program to disable the trackpad for a short time whenever a keyboard key is pressed. It's worked well for me on El Capitan so far -- hopefully it helps some of you as well: https://github.com/thesyntaxinator/TouchGuard

OMG! I've been plagued and tormented by issue of erratic, maniacal jumping of my cursor on my mid-2015 retina MBP ever since its initial boot-up in 2017.
Cannot believe something as simple as turning off tap to click in System Preferences appears to have solved my agony.

Will your "fix" work with Mojave 10.14.2?
Ideally, I'd hope to be able to have "tap to click" turned on, but automatically turn off only when I'm typing and then turn itself back on again.

Thanks

update: Just realised I'm in MacBook forum.
I actually have a MacBook Pro - but the issue seems the same. And now that I see turning off "tap to click" has stopped the spastic cursor behaviour - I'm even more anxious to receive a reply to my query above.

I also have a problem with the trackpad on a mid 2015 MacBook Pro Retina.
When I move the cursor across the screen it very often "picks us" an item, for example, one of my saved bookmarks in the toolbar, or an application from the dock and drags it to another position. Usually I notice what is happening and can correct it but sometimes items end up in wrong folders.
Has anyone else experienced this and is there a fix?
I bought the MacBook Pro used about 2 years ago and it has always done this.
