Do you keep switching between different email clients? Or wish that you could easily start your preferred email application, instead of having to do it manually? If so, you can easily change this by changing your default “Mail” app preference.

In Mac OS X, the default setting for email is set as “Mail” app, which functions very well. However, if you have a specific email service that you stick to, you can always make it your default choice.

How to Change the Default Mail App Client in Mac OS X

Here’s How to Change Default Mail App Client in Mac OS X:

Note: You can not change default Mail client before setting up at least one account in “Mail” app. Once you setup one account with “Mail” app, follow below steps.

Step 1: Open “Applications” (in Finder) and then on “Mail.”

Step 2: Click on the Mail Menu and choose “Preferences” from it.

Step 3: Tap on “General” option

Step 4: There will be a drop-down menu near “Default email reader” Use it to select your preferred account. If your desired account is not visible, click on “Select” to search for your email client and choose the one you want.

Step 5: Quit the preference box after saving your email client.

Note: While using the “Select” option (as written in Step 4), you will have the Finder window to select the apps stored in any drive of your Mac OS X. Still, we would recommend to store the email clients in Folder, so that you can easily find it using Applications > Folder option.

After you have selected your default email client, you will always land in the selected email client whenever and wherever you click within the Mac. You can always repeat the above steps to change your email clients or restoring the default Mail app.

    What if the default client does not “save”? There’s no Save option, once selected you just have to quit, but on my system it keeps reverting to a redundant parallels version of Office that I uninstalled months ago.

      Bryan, hi. I have the same issue. Trying to set up MAIL as a default program but it changes back to Outlook automatically. Let me know to dtanyukhin (at) gmail.com please if you manage to fix it and how. Thanks!

    You can’t get into preferences of MAIL without setting an account there first. How annoying… Btw: your screenshot how to go to the Settings is not right. It’s a screenshot of Finder > Preferences.
