Atom has taken over as the default application for some file types on my computer and it will not relinquish. It should not become the default editor for ANY file types unless I explicitly tell it to. This is how every other editor I have used works.
For example, since installing Atom all CSV file now open in Atom. I have tried to revert this by “open with > other > always open with” Numbers but sure enough the next time I try to open a CSV it opens Atom.
I have not been able to find any settings under preference to change this behavior in Atom.
