Some users fail to authenticate their Gmail account in the Mail app on Mac. If you are also facing the same, we bring some working solutions to fix the Gmail login failure in the Mail app on Mac.

1. Check Your Internet Connection

Starting with some basic solutions, we suggest running a speed test on your Mac to check the strength of your internet connection. If you have a dual-band Wi-Fi router, we suggest switching to a 5GHz frequency band and sitting closer to the router. Try logging in again to your Gmail account. If this doesn’t help, refer to the next solutions.

2. Check Email Address and Password

If you have multiple email accounts in the Mail app, sometimes you might use the wrong Gmail account. Also, check the password you are entering is correct.

5. Enable Access for Less Secure Apps

Your Google account suggests limiting email access for apps with less security. Your Google account may have considered the Mail app on your Mac to be a less secure one. Here’s how you can check and fix the same. Note that this option won’t be available for accounts with Two-Factor Authentication turned on.

Step 7: Close the browser window and open the Mail app to check if the problem is solved.

6. Switch to Safari as Default Browser

Whenever you sign in to your email account using the Mail app, the authentication process takes place in your browser. If you are not using Safari as your default browser, you can try doing that to fix the Gmail login error in the Mail app. Here’s how.

Step 1: Press Command + Spacebar to open Spotlight Search, type System Settings, and press Return.
