Solution 1Recommended

Download a Legacy Office for Mac Installer

Download a specific historical release of Microsoft Office that remains compatible with your current macOS version.

While the Mac App Store only provides the newest version of Microsoft Office that requires macOS 12 or newer, you can still manually download and install an older, compatible version directly from Microsoft's update servers.

1
Identify your macOS version

Click the Apple icon in the top-left corner of your screen and select 'About This Mac' to check your exact version (e.g., macOS Big Sur 11.7.10).

2
Visit the Microsoft Update History page

Open your web browser and navigate to the official Microsoft page for 'Update history for Office for Mac'.

3
Locate Version 16.77

Scroll down the list of release dates to find version 16.77 (released in September 2023), which is the last supported version for macOS Big Sur 11.

4
Download the Installer

Click the download link for the 'Office suite (with Teams)' or the individual 'PowerPoint' package next to version 16.77 to download the .pkg file.

5
Install and Activate

Open the downloaded .pkg file, follow the on-screen instructions to install PowerPoint, and log in with your Microsoft 365 credentials to activate.

Frequently Asked Questions

Can I still edit new PowerPoint files on an older Mac?

Yes, installing a legacy version like Office 16.77 on macOS Big Sur will still allow you to open, edit, and save modern .pptx files seamlessly, even without the newest feature updates.

Why does the Mac App Store say PowerPoint is incompatible?

The Mac App Store automatically distributes the most current version of an application. Since the latest Microsoft Office requires macOS 12 or newer, the App Store prevents installation on older OS versions. You must use the direct .pkg installer from Microsoft's website instead.

Will my Microsoft 365 subscription work with older Office versions?

Yes, your Microsoft 365 subscription is fully valid for older versions of Office. Once you install the compatible legacy version, simply sign in with your Microsoft account to activate the software.

Is there a free alternative if my Mac is too old for Microsoft Office?

Yes, WPS Office is an excellent free alternative. It is highly compatible with Microsoft Presentation formats, runs efficiently on older Macs, and provides a familiar interface for creating and editing presentations.
