Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Armand,
If the Microsoft 365 installer is showing a message that macOS 11 (Big Sur) or later is required, it means your Mac is currently running an older version of macOS that is not supported by the latest Microsoft 365 apps.
You can check your macOS version by selecting Apple menu > About This Mac.
If your Mac supports an upgrade to macOS 11 or later, I recommend updating macOS first and then downloading Microsoft 365 again.
If your Mac cannot be upgraded to macOS 11 or later because of hardware limitations, unfortunately the current version of Microsoft 365 cannot be installed on that device.
In that case, you can still access Microsoft apps through the web browser using:
- Log in to https://www.office.com
- Go to More apps
For more information, please refer to the following link:
- Update Microsoft 365 or Office on your macOS or iOS device
- System requirements for Microsoft 365 for home use
- Upgrade macOS to continue receiving Microsoft 365 and Office for Mac updates
- Download, install, or reinstall Microsoft 365 or Office 2024 on a PC or Mac
I hope everything gets sorted out soon. Please keep me posted on any updates.
Kind regards,
