This fixed my issue, thanks.

Worked for me too. Thank you!

I ran this script today. I got the output:

/Applications/Atom.app/

Exists: /Applications/Atom.app/
/Users/xxx/Library/Caches/com.github.atom.ShipIt
Exists: /Users/bradley/Library/Caches/com.github.atom.ShipIt
/Users/xxx/Library/Application Support/com.github.atom.ShipIt

It did not fix the problem.
