How to Install Microsoft 365 on macOS 12.7.6 When macOS 13 is Required
Question details
The user needs to install Microsoft 365 on a Mac running macOS 12.7.6, but the installer requires macOS 13 or newer.
- Product
- Microsoft 365
- Device & OS
- macOS 12.7.6
- Scenario
- Attempting to install Microsoft 365 on an older Mac that is fully updated but cannot be upgraded to macOS 13 (Ventura) or newer.
- Observed behavior
- The Microsoft 365 installer fails to proceed, displaying an error stating that macOS 13 or later is required to install the software.
Ensure you have your Microsoft 365 account credentials ready, and close any running Office applications before attempting to reinstall or modify your setup.
Install a Compatible Older Office Build (Version 16.88)
By completely removing existing Office apps and licenses, you can install the last official build that supported macOS 12.
Microsoft only supports the three most recent major versions of macOS. If your Mac is restricted to macOS 12.7.6, you must download an older, compatible version of Microsoft 365, such as version 16.88.
Open the 'Applications' folder on your Mac. Drag Microsoft Word, Excel, PowerPoint, and Outlook to the Trash to remove the incompatible versions.
Download and run the official Microsoft License Removal Tool for Mac to clear any conflicting license data from previous installation attempts.
Navigate to the official 'Update history for Office for Mac' page on Microsoft's website. Locate and download the installer package for version 16.88.
Run the downloaded version 16.88 installer. Once the installation is complete, launch Word or Excel and sign in with your Microsoft 365 account to activate the software.
Try WPS Office for seamless document editing on your Mac
If you are tired of OS version restrictions and compatibility blocks from Microsoft 365, WPS Office offers a powerful, lightweight, and free alternative that works smoothly across a wide range of macOS versions.
- 1. Download WPS Office: Visit the official WPS website and download the Mac installer compatible with your OS.
- 2. Install on your Mac: Open the downloaded package and drag the WPS Office icon into your Applications folder.
- 3. Open Office Files: Launch WPS Office and seamlessly open, edit, and save your existing Office documents.
Frequently Asked Questions
Why is Microsoft 365 requiring macOS 13 on my Mac?
Microsoft’s official policy is to support only the three most recent major versions of macOS. With the release of newer macOS versions, macOS 12 (Monterey) is no longer in the supported window for the latest Microsoft 365 updates.
Is Microsoft Office version 16.88 safe to use?
Yes, version 16.88 is an official release from Microsoft and is the last build that fully supports macOS 12. While safe, it will not receive new feature updates.
Can I upgrade my Mac to macOS 13 to fix this issue?
It depends on your Mac model. Check Apple's official compatibility list for macOS 13 (Ventura). If your Mac was manufactured before 2017, it may not support macOS 13, making an older Office build your best option.
Will I lose my documents if I uninstall the current Office apps?
No, uninstalling Microsoft Office applications does not delete your personal documents, spreadsheets, or presentations. However, it is always recommended to back up your files before making system changes.
