Question details
The user wants to know if they can install and run the latest version of Microsoft Excel on an older Mac operating system, specifically macOS 10.12.16 (Sierra).

- Product
- Microsoft Excel
- Device & OS
- macOS 10.12.16
- Scenario
- Attempting to install, update, or run the newest Microsoft 365 or Office for Mac releases on an older Mac device running Sierra.
- Observed behavior
- Current Office releases are unsupported on macOS 10.12.16, preventing the installation of the desktop application and halting all further software and security updates.
Check your Mac's hardware specifications by clicking the Apple logo and selecting 'About This Mac' to see if your device supports upgrading to a newer macOS version.
Use Microsoft Excel for the Web
If you cannot upgrade your Mac's operating system, using the web-based version of Microsoft Excel is the best way to access the latest features without installing the desktop application.
Microsoft offers a free, web-based version of its Office applications. This allows users on older operating systems to create, edit, and collaborate on spreadsheets directly from their browser.
Launch Safari, Google Chrome, Firefox, or any modern web browser available on your Mac.
Go to Office.com or OneDrive.com.
Log in using your personal, work, or school Microsoft account credentials.
Click the Excel icon from the sidebar to open the web application and begin working on your spreadsheets.
Upgrade Your Mac Operating System
Updating macOS to a more recent version is the only official way to install and run the latest desktop release of Microsoft Excel.
Use WPS Office as a Lightweight Alternative for Older Macs
If your Mac hardware cannot be upgraded and Microsoft Excel is no longer supported, WPS Office provides a free, lightweight, and robust alternative. It functions smoothly on a wide range of devices and handles complex spreadsheets natively, meaning you don't need to replace your Mac to stay productive.
- 1. Download WPS Office for Mac: Navigate to the official WPS website and download the Mac installer.
- 2. Install the Application: Open the downloaded package and drag the WPS Office icon to your Applications folder.
- 3. Open Your Excel Files: Launch WPS Spreadsheet and seamlessly open any existing .xlsx or .xls files.

Frequently Asked Questions
Why can't I install the latest Microsoft Office on macOS Sierra?
Microsoft updates its system requirements regularly to support new features and security protocols. They officially support only the three most recent major versions of macOS, meaning older versions like Sierra (10.12.16) are phased out from updates and new installations.
Can I download an older version of Microsoft Excel that works on macOS 10.12.16?
If you previously purchased an older standalone version, such as Office 2016 for Mac, you might still be able to download the installer from your Microsoft account's purchase history. However, be aware that these versions no longer receive security updates.
Does Excel for the Web have all the same features as the desktop app?
Excel for the Web handles most daily tasks, basic formatting, and standard formulas perfectly. However, it lacks some advanced desktop features, such as complex VBA macros, Power Pivot, and certain advanced data connection tools.
Are there other free spreadsheet apps that work on older Macs?
Yes. In addition to Excel for the Web, you can use Apple's built-in Numbers app, web-based tools like Google Sheets, or open-source desktop alternatives like LibreOffice, provided they still offer a legacy version for macOS Sierra.
