Unfortunately, Catalina has been marred with bugs ever since the developer beta began. This has extended to many applications, including Apple’s own Mail app.

One frustrating issue has been when the Mail app opens in split screen all by itself.

Mail opening in Split Screen on macOS Catalina

This bug may not be exactly new to Catalina, but the Apple Mail app has been wreaking havoc on users for quite some time. Whenever a new version of macOS is released, there are expectations that “major” bugs would be fixed. In the case of Mail opening in Split Screen, that is simply not the case.

Notably, the problem seems to occur if you are working in a fullscreen of another application. An example of this may be browsing Reddit or watching YouTube in Safari in full-screen mode. Then, seemingly out of nowhere, the Mail app decides to just open itself in a split-screen view.

This seemingly occurs due to some bugs found when you have Gmail connected to Mail. Every once in a while, the authentication between Google and Apple Mail will seemingly fail. This causes Mail to open up on its own, causing you to re-authenticate the login.

Since the bug is related to Gmail, you’ll want to go through and remove the account from Mail before doing anything else. Here is how you remove an account:

  1. Open the Mail app on your Mac
  2. Click Mail in the menu bar
  3. Select Accounts from the drop-down
  4. Highlight the Google account you want removed
  5. Tap the “-” button on the side
  6. Click Ok to confirm

  1. Open your browser and navigate to your Google Account Security Settings
  2. Scroll down and select 2-Step Verification
  3. Login and confirm your Google account email and password
  4. Toggle 2-Step Verification On

From here, you are given the option to either use a Google prompt, or through a text message with verification codes. When you use a Google prompt, you must have the Google app installed on your phone, and a notification will arrive confirming that you are logged in.

When completed, go back to the main Security Settings page and select App Passwords. In the box, hit the first drop down and select Mail, and in the second box select Mac. Then tap Generate. This will create a password only to be used with your Gmail account along with the Mail app on your Mac.

Now that the App Password has been generated, you need to open the Apple Mail app on your Mac. Then follow these steps:

  1. Click Mail in the menu bar
  2. Select Accounts from the drop-down
  3. Click the “+” button at the bottom
  4. Select Other Accounts from the list of options
  5. Select Mail account
  6. Enter your Gmail email account and the App Password that you created earlier
  7. Tap Sign In

After you have signed in, the Mail app will ask whether you want to sync Mail and Notes with this account. Leave Mail checked, and you can either choose to sync Notes or not, then press Done.

Now that the account has been added, it will take some time for the Mail app to sync the data between your Gmail account and the app itself. However, once completed, you should not run into anymore instances of macOS Catalina’s Mail app opening itself.
