By default, clicking on an email address from another mac app (such as Slack) launches the Mail.app application in a compose view to that email address.

I would like to disable this - I never use the Mail.app and most times I encounter an email address I'd like to copy/paste it somewhere else, not compose an email to that person.

Is there a way to disable that behavior?

  • It's going to open something, whatever your default mailer is. Right-click/Copy Link if you don't want to open a mailer. – Tetsujin Apr 20 '16 at 18:07

Notwithstanding any sneaky Terminal commands I know not about, OS X will always have the need to open some app upon clicking an e-mail link. Literally any app of your liking will do.

Such an app might be an app you don't mind being opened. Like… the Finder!

  1. Open Mail Preferences and go to the first tab, General. Choose the pop-up menu for Default email reader and pick Select….

    Picking another e-mail client

  2. Choose Macintosh HD (or whatever you've renamed your boot volume to) → System → Library → CoreServices → Finder.app.

    Choosing the Finder

  3. Try it out! (I can't post mailto: links here though. 😕)

If you work with spaces or full-screen apps, clicking a mail link might switch spaces. But at least no apps are launched. On my computer, not even a new Finder window is opened.

    This works for changing the email reader but mailto: links still open the Mail.app. I found a working answer here: superuser.com/questions/1067771/… – johncorser Apr 21 '16 at 18:33
  • The "reader" part of the option is there because it's hard to name settings for the average user. What else could that setting do? (Compare with the "newsreader" setting for RSS in older Safari versions.) In any case, it did work on my El Capitan, but there seems to be a LaunchServices cache bug which accidentally reverts changes to the setting—the workaround is /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user and a reboot. The linked answer might be better though. – Constantino Tsarouhas Apr 21 '16 at 22:54

    @johncorser I have mine set up to open the browser app I use. For Firefox this makes the mailto: links do nothing. – farmerjoe Aug 30 '16 at 17:29
  • @johncorser I got the same results as farmerjoe using Chrome. – intcreator Aug 7 '17 at 23:00
  • This unfortunately doesn't work for me. In the dropdown I can only select Mail app and if I choose anything else in applications, it seems to reset every time I close Mail app. I'm on El Capitan. Anyone has any workaround? – Josep Valls Aug 19 '17 at 16:17

Had the same problem here, but decided to do a little more. Instead of opening the "Finder" app, I used the "Automator" to create an application that literally does nothing!

The key is to save the Automator project and them put a command on it that will close the same Application you're editing! Them just set it as the default mail application. This way you won't have to worry about some application opening when you click in the address.

I made a simple tutorial with some screenshots if you want to check it out:
