[Ruby] How to change Finder’s default text editor to Atom

less than 1 minute read

I couldn’t change the default text editor from System Preferences, so I tried to find out how to do it.


  1. Right-click on the appropriate text file from Finder and select “Get Info”
  2. ▼ Select the text editor you want to set from this application (Atom this time)
  3. Complete the setting with “Change All” below.

It seems that you can select an editor for each file by skipping 3.
