Atom Uninstall

No, the Atom text editor does not have an uninstaller. On Mac OS X, to completely uninstall, remove the following files and directories:

/usr/local/bin/atom (NB only present if command line tools installed)
/usr/local/bin/apm  (NB only present if command line tools installed)
~/Library/Application Support/
~/Library/Application Support/com.github.atom.ShipIt
~/Library/Application Support/Atom
~/Library/Saved Application State/com.github.atom.savedState
~/Library/Saved Application State/com.github.atom.savedState

NB: The <letter/numbers> in the file name located in ~/Library/Preferences/ByHost appear to be a unique string per machine.

NB: Some of these files/directories may not be present. Older installations are likely to have all of them. Some of them aren’t on my system with a new Atom install.

DO NOT, UNDER ANY CIRCUMSTANCES, COPY AND PASTE THE CODE ABOVE INTO THE TERMINAL WITH rm. The code contains spaces and cannot be used on the command line without escaping the spaces.
