How to Install Microsoft Office on a 2012 iMac Running macOS Catalina
Question details
The user is unable to install a newly purchased Microsoft Office Home & Student package because the current installer is incompatible with the operating system on their older Mac.
- Product
- Microsoft Office Home & Student
- Device & OS
- 2012 iMac running macOS Catalina 10.15.7
- Scenario
- Attempting to install a purchased Microsoft Office suite on an older Mac operating system.
- Observed behavior
- The standard Microsoft Office installation fails or blocks the user, stating that the software requires a newer version of macOS than Catalina 10.15.7.
Verify that your iMac is running exactly macOS 10.15.7 by clicking the Apple menu and selecting 'About This Mac', and ensure you have your Microsoft account credentials ready.
Download and Install Office for Mac Version 16.66
Version 16.66 is the final build of Microsoft Office that officially supports macOS Catalina 10.15. Installing this specific version bypasses the incompatibility of newer installers.
Newer versions of Microsoft Office require macOS Big Sur (11) or later. To use Office on a 2012 iMac running Catalina, you must download the specific historical release (16.66) that retains compatibility with your system.
Navigate to the official Microsoft Office update history page for Mac and download the installer package for version 16.66 (released in October 2022).
Double-click the downloaded .pkg file and follow the on-screen prompts to install the Office suite onto your iMac.
Open any installed application, such as Microsoft Word, click 'Sign In', and enter the Microsoft account associated with your purchased Home & Student license.
Redeem Boxed Software Online
If you purchased a physical retail box, the included installation media might be incompatible. Redeeming your key online allows you to link the license to your account and download the correct older version.
Try WPS Office for Seamless Mac Compatibility
If you are struggling with Microsoft Office version restrictions on your 2012 iMac, WPS Office is an excellent, lightweight alternative. It provides excellent performance on older macOS versions while maintaining robust compatibility with all your existing documents.
- 1. Download the Mac version: Visit the official WPS Office website and click the free download button for macOS.
- 2. Install the software: Open the downloaded package and drag the WPS Office icon into your Applications folder.
- 3. Open existing files: Launch WPS Office and directly open your Microsoft Word, Excel, or PowerPoint files without needing any format conversion.
Frequently Asked Questions
Why can't I install the latest Microsoft Office on macOS Catalina?
Microsoft officially supports only the three most recent versions of macOS for its latest Office updates. Because Apple has released several newer operating systems since Catalina, Microsoft no longer provides new Office installers compatible with it.
Is Microsoft Office version 16.66 safe to use on my iMac?
Yes, version 16.66 is an official release from Microsoft. However, because it is an older build, it will not receive new feature updates or the latest security patches. It will still function normally for creating and editing documents.
Will my Home & Student product key work with older Office versions?
Yes. As long as your product key is valid for a compatible perpetual license (like Office 2019 or 2021 for Mac), signing into version 16.66 with the Microsoft account linked to that key will successfully activate the software.
