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.

Check macOS compatibility

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).

2
Download the installer

Click the download link for the identified legacy version (usually a .pkg file) directly from the Microsoft release history table.

3
Install and activate

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.
