Solution 1Recommended

Clear the Authentication Session by Restarting

A simple restart of both your browser and operating system can clear temporary session glitches that cause the redirect loop.

Authentication servers sometimes fail to register your login token if there is a conflict in temporary browser data. Restarting forces a fresh connection.

1
Quit your browser completely

Do not just close the window. Click on the browser's name in the top menu bar (e.g., Safari or Chrome) and select 'Quit'.

2
Restart your Mac

Click the Apple menu in the top-left corner of your screen and select 'Restart'. Wait for the system to boot up fully.

3
Sign in again

Open your browser, navigate directly to https://www.office.com/signin, and log in with the account associated with your Office purchase.

4
Initiate the download

Once logged in successfully, locate your Office 2021 product in your account dashboard and click the 'Install' or 'Download' button.

Clear the Authentication Session by Restarting
Check Your Downloads Folder: Sometimes the download actually starts in the background during the loop. Check your Mac's Downloads folder for a file named like 'Microsoft_Office_Installer.pkg'.
