How to Install a Microsoft Office Version Compatible with macOS Monterey 12.7

The newest Microsoft 365 installer can require a newer macOS release than Monterey 12.7. When the Mac cannot be upgraded, install an older Office for Mac build from Microsoft’s official update history and prevent AutoUpdate from immediately replacing it with an incompatible build.

Choose an Office Build That Still Runs on Monterey

For the source scenario, use Office for Mac version 16.88 or earlier. Microsoft supports only a moving set of recent macOS versions, so confirm the version requirement in the official Office for Mac release notes before installation.

Download and Install the Compatible Office Release

1. Open Apple menu > About This Mac and confirm the Mac is running macOS Monterey 12.7.
2. Visit Microsoft’s Update history for Office for Mac page and locate version 16.88 or an earlier compatible build.
3. Download the Microsoft installer package, close all Office apps, and install it. Avoid third-party download archives.
4. Launch Word or Excel, sign in with the Microsoft account that owns the subscription, and confirm activation under the app’s account or license screen.

Stop Microsoft AutoUpdate from Installing an Incompatible Build

Open an Office app, choose Help > Check for Updates, and review Microsoft AutoUpdate settings. Turn off automatic installation if it would move the Mac beyond the last compatible build. You will also stop receiving newer Office security updates, so treat this as a temporary compatibility measure.

Understand the Security Tradeoff

An older Office build may no longer receive fixes even though it launches. Back up documents, avoid untrusted macros, and plan either a supported macOS upgrade, newer hardware, or a maintained Office-compatible application.

WPS Office cannot change Microsoft 365 installer requirements, subscription state, or the support lifecycle of Office for Mac.

If the current WPS Office for Mac system requirements include your Mac, it can provide a free, lightweight alternative for common DOCX, XLSX, PPTX, and PDF files with a familiar interface, PDF tools, core document features, and WPS AI assistance. Check the current macOS requirement before downloading, and test macros, add-ins, specialized fonts, and cloud integrations in sample files before migrating.
