Changing Mac OS X’s Default E-Mail Application

It doesn’t have to be Mail.

By default, Mac OS X is pre-configured with Mail, Apple’s e-mail application, set as the default e-mail client. That means clicking a link to an e-mail address or accessing your e-mail program from within another application will automatically launch Mail.

But you can easily change it to an e-mail client you prefer. Here’s how:

  1. Open Mail.
  2. Choose Mail > Preferences to open the preferences window.
  3. General Mail PreferencesIf necessary, click the General button in the preferences window’s toolbar to display General options.
  4. Choose the mail client you prefer from the Default email reader pop-up menu. If the application is not listed by name, you can choose Select from the menu and use the dialog that appears to locate and select the e-mail client you want. (Obviously, the application must be installed on your computer to select it.)
  5. Click the window’s close button to dismiss it.
  6. Choose Mail > Quit Mail to quit Mail.

Changes take affect as soon as you quit Mail.

Note that the preferences window shown here is for Mac OS X 10.5 Leopard. These steps also work in Tiger, although the preferences window may look different.
