Autocapitalization on Mac High Sierra


I hope this is something simple (and feel stupid about asking later on).

Everytime I start typing in a file on Atom, the first word is automatically capitalized.

do changes to “Do”

fo changes to “Fo”.

How can I turn this off? Thanx.


Does this happen when you start Atom from the Terminal with atom --safe?



Any suggestions on how I track down what is causing it in normal mode?


And thank you.


Never mind. I take that back. It still does it.


Please consider this solved.

On a related note, I hate TextExpander.
