I set the default email reader to be Airmail a second time. I checked the default mail client setting within “Apple Mail” preferences, it had reset back to “Apple Mail”. I tested an email link from a website to check that this was a system wide rather than an issue specific to Tweetbox. I made the change, closed “Apple Mail” and tried again! This done, the field that needed changing was obvious, Preferences > General > Default email reader This was not a problem, although I did have to create an account within “Apple Mail” before the preferences pane became accessible.

Googling revealed that I needed to make this change under “Apple Mail” > Preferences, rather than System Preferences. What should have been a quick change of settings turned into a 10 minute battle with El Capitan to change the default mail client! I wanted to quickly share a tweet from Tweetbot to a friend by email, I was surprised when “Apple Mail” launched and asked me to setup an email account, I do not use “Apple Mail” I was using Airmail as my primary email client at the time. Launch “Apple Mail” > Preferences > General – Change the default mail client Go into System Preferences > iCloud – sign out! Intended Audience: Anybody struggling to change the default OSX Mail Client under El Capitan In later releases of OSX 10.11 the procedure may be more simple than the steps I took with 10.11.1 January 2017 update: On a fresh installation of macOS Sierra, changing the default mail client was significantly less painful! I launched “Apple Mail” added an account, from “Apple Mail” preferences I was able to simply change the default mail client, this appears to have made the change without issue.Īugust 2016 update: Please take a look at the comments before embarking on the fix detailed below.
