- Device & OS
- Mac
- Scenario
- Attempting to download the Office installer from the official Microsoft website after completing a purchase.
- Observed behavior
- The web browser continuously loops back to the Microsoft sign-in page, preventing the installer download from initiating.
Ensure you know the exact Microsoft account credentials used to purchase Office 2021 and verify your internet connection is stable.
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.
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'.
Click the Apple menu in the top-left corner of your screen and select 'Restart'. Wait for the system to boot up fully.
Open your browser, navigate directly to https://www.office.com/signin, and log in with the account associated with your Office purchase.
Once logged in successfully, locate your Office 2021 product in your account dashboard and click the 'Install' or 'Download' button.
