How to Install Microsoft 365 on macOS Monterey 12.7.6
Question details
The user wants to install Microsoft 365 on a Mac running macOS Monterey 12.7.6, but the latest Microsoft 365 installers require macOS 13 (Ventura) or later.
- Product
- Microsoft 365
- Device & OS
- macOS Monterey 12.7.6
- Scenario
- Installing Microsoft Office on an older macOS version that is no longer supported by the latest Microsoft 365 installers.
- Observed behavior
- The newest Microsoft 365 installer fails or blocks installation, prompting the user that macOS 13 or a newer operating system is required.
Verify your current macOS version by clicking the Apple menu and selecting 'About This Mac', and ensure your Microsoft 365 subscription is active before proceeding with a legacy installer.
Download and Install Office for Mac Version 16.88
Version 16.88 is the last officially supported build for macOS Monterey. Installing this older version allows you to use Microsoft 365 without upgrading your operating system.
Microsoft only supports the three most recent major versions of macOS. When newer macOS versions are released, older ones like Monterey drop out of support for the latest Office updates.
To bypass the OS restriction, you need to download the final build compatible with Monterey, which is version 16.88.
Visit the official Microsoft Support release history page for Office for Mac, or search for the Office version 16.88 installer package.
Select and download the Office for Mac version 16.88 installer (.pkg file). You can choose the package either with or without Microsoft Teams, depending on your workflow needs.
Navigate to your Mac's Downloads folder, double-click the downloaded .pkg file, and follow the on-screen prompts to complete the installation.
Launch Word or Excel from your Applications folder, enter your Microsoft account credentials, and sign in to activate your existing Microsoft 365 subscription.
Use WPS Office as a Lightweight Alternative for Mac
If you are struggling with macOS compatibility issues and heavy installer requirements, WPS Office offers a free, lightweight, and highly compatible alternative to Microsoft 365 that runs perfectly on older Macs.
- 1. Download the App: Visit the official WPS Office website and click 'Free Download' for Mac.
- 2. Install WPS Office: Open the downloaded DMG file and drag the WPS Office icon into your Applications folder.
- 3. Start Creating: Launch the application, easily sign in, and immediately open your existing Microsoft Office files without any compatibility prompts.
Frequently Asked Questions
Why can't I install the latest Microsoft 365 on macOS Monterey?
Microsoft policy dictates that Microsoft 365 updates are only supported on the three most recent major versions of macOS. When macOS Sonoma was released, macOS Monterey fell out of this support window, meaning it can no longer run the newest Office builds.
Is it safe to run version 16.88 of Office for Mac?
Yes, version 16.88 is a genuine and official Microsoft release. However, because it is an older build, it will eventually stop receiving security updates, so users should keep this in mind long-term.
Can I upgrade my macOS to fix this issue?
Yes, if your Mac hardware meets Apple's system requirements, you can upgrade your operating system to macOS Ventura (macOS 13) or later. Once upgraded, you will be able to install the most recent version of Microsoft 365 without errors.
Do I need a different Microsoft 365 subscription for older Mac versions?
No. Your existing Microsoft 365 Personal, Family, or Business subscription is perfectly valid and will activate older versions like 16.88 just as easily as it activates the newest releases.
