How to Install Microsoft 365 on macOS Big Sur (2014 MacBook Air)
Question details
The user needs to install Microsoft 365 on a 2014 MacBook Air that is capped at macOS Big Sur 11.7.10.
- Product
- Microsoft 365 (Office for Mac)
- Device & OS
- macOS Big Sur 11.7.10
- Scenario
- Attempting to install Microsoft Office on an older Mac that cannot be upgraded to macOS Ventura or later.
- Observed behavior
- The current Microsoft 365 installer fails or displays an incompatibility error because it requires a newer macOS version.
Verify your exact macOS version by clicking the Apple menu and selecting 'About This Mac'. Ensure you have your Microsoft account login credentials ready before downloading older installers.
Download and Install Office Version 16.77
Version 16.77 is the last officially supported Microsoft Office build for macOS Big Sur.
Because your 2014 MacBook Air cannot be upgraded past macOS Big Sur, the latest Microsoft 365 installers will not work. You must download a specific older release that remains compatible with your operating system.
Navigate to the official Microsoft 'Update history for Office for Mac' page in your web browser.
Scroll down the list of releases to find version 16.77 (released in September 2023). Click the download link for the full Office suite installer.
Open the downloaded .pkg file and follow the on-screen installation prompts to install Microsoft 365 on your Mac.
Launch any Office app, such as Word, and sign in with the Microsoft account associated with your active Microsoft 365 subscription.
Try WPS Office for a Lightweight Mac Experience
If you are struggling with older, unsupported versions of Microsoft 365 on your 2014 MacBook Air, consider WPS Office. It provides a lightweight, fast, and fully compatible Office alternative that runs smoothly on older Macs without expensive subscriptions.
- 1. Download WPS for Mac: Visit the official WPS Office website and click 'Free Download' to get the Mac installer.
- 2. Install the Application: Open the downloaded .dmg file and drag the WPS Office icon into your Applications folder.
- 3. Launch and Create: Open WPS Office from your Applications folder to instantly start editing or creating documents.
Frequently Asked Questions
Can I still get security updates for Office 16.77 on macOS Big Sur?

Where can I find the Office license removal tool?
The Microsoft Office License Removal Tool can be downloaded directly from the official Microsoft Support website. Search for 'How to remove Office license files on a Mac' in your browser to find the download link.
Does my Microsoft 365 subscription still cover older versions like 16.77?
Yes, your active Microsoft 365 subscription allows you to activate older versions of Office, including 16.77, as long as it is tied to the correct Microsoft account.
Why does the Mac App Store say Microsoft 365 is incompatible?
The Mac App Store always offers the latest version of Microsoft 365, which requires macOS Ventura or later. To get older versions, you must download the installer packages directly from Microsoft's update history website.
