- Product
- Microsoft Office for Mac
- Device & OS
- macOS (2017 MacBook Air)
- Scenario
- Attempting to install or update Microsoft Office on an older MacBook Air with an unsupported macOS version and an expired license.
- Observed behavior
- The latest Microsoft 365 apps fail to install due to the older macOS version, requiring the user to find a legacy compatible release.

Download a Compatible Older Version of Microsoft Office
Identify your macOS version and download the corresponding legacy Office installer from Microsoft's update history.
Microsoft 365 for Mac only supports the three most recent major versions of macOS. If your 2017 MacBook Air cannot upgrade to these latest operating systems, you must install an older, frozen build of Office that supports your current macOS.
Consult the official Microsoft Office for Mac update history page to find the last supported build for your specific macOS version (e.g., macOS Catalina or Big Sur).
Click the download link for the identified legacy version (usually a .pkg file) directly from the Microsoft release history table.
Run the downloaded installer and follow the on-screen prompts. Once installed, sign in with an active, valid Microsoft license or product key to activate the software.

Use WPS Office as a Lightweight Alternative for Older Macs
If your 2017 MacBook Air struggles with heavy Microsoft Office installations or you have an expired license, WPS Office is the perfect free substitute. It is lightweight, highly compatible with older macOS versions, and seamlessly handles all standard Word, Excel, and PowerPoint files without the need for expensive subscriptions.
- 1. Download the installer: Go to the official WPS Office website and click the 'Free Download' button for Mac.
- 2. Install the application: Open the downloaded .dmg file and drag the WPS Office icon into your Applications folder.
- 3. Open your files: Launch WPS Office and instantly open your existing Microsoft Office documents to continue working seamlessly.
