title: How do I change the external editor for GitHub client on MAC or Windows?
body: <p>I am using GitHub client on MAC OS X 10.10.
  (Please note that I am not using GitHub for Enterprise.)</p>
  
  <p>I noticed that when there is a merge conflict, GitHub Client is prompting me to either resolve the conflict using Finder or External Editor. I do not see the file in merge conflict within GitHub client itself. So I want to setup one of the editor ( I am using Brackets) as a external editor.</p>
  
  <p>In current scenario, when I click on <strong><em>External Editor</em></strong> button in GitHub (which is shown when merge conflict happens), I see the file in merge conflict in <em><strong>Safari</strong></em> browser.</p>
  
  <p>I also looked at git command prompt options to see if there is a way change the setting for GitHub client using terminal window. </p>
  
  <p>So far I found out that I can setup core.editor global config for git terminal/command line tool only, but not able to set the external editor of my choice for GitHub client.</p>
  
  <p>Any suggestion will be appreciated.</p>
