Office 2021 for Mac End of Support: What to Do Now
Support ended on October 13, 2026. Your apps may keep working, but the security updates have stopped. Here's what that means, and how to choose what's next.
Quick Answer
- ✓Office 2021 can keep running, but Microsoft no longer provides security fixes, bug fixes or support, and there's no extension.
- ✓If it went read-only, that's a separate bug. Update to version 16.114.3 or later.
- ✓Your options: stay for now, buy Office 2024, subscribe to Microsoft 365, or switch to a free app.
What does end of support mean?
Microsoft's lifecycle page lists the end date for all Office 2021 editions, including Home & Student and Home & Business for Mac. Microsoft says the apps may continue to function, but warns about security risk. Your license hasn't expired, and your files are yours. What stopped is maintenance: new security holes won't be patched.
On a Mac, there's a practical concern too. Older Office apps can eventually stop working well with new versions of macOS, and Office 2019 users have already seen editing restricted some years after its support ended. Nobody outside Microsoft knows the timeline for Office 2021, so it's sensible to plan ahead, but there's no need to panic.
How to decide what to do
Start from how you actually use Office.
You rarely use it
A free app probably covers you. FileHop, Pages, Numbers or LibreOffice can all open your files.
You use it often, and hate subscriptions
Office 2024 is the one-time purchase. It will also reach end of support, so it delays the same decision.
You need the latest Office
Microsoft 365 keeps updating while you subscribe, and it's Microsoft's recommended path.
You share complex files for work
Stay with real Office. Macros, tracked-changes drafting and complex layouts are where alternatives fall short.
If you keep Office 2021 for now, take extra care with attachments from strangers, since security holes are no longer patched.
Free ways to keep working
None of these is a perfect Office clone. Each is good at something.
LibreOffice
A full free office suite for Mac that works completely offline. It creates charts and pivot tables, but complex Office files can shift.
Pages, Numbers and Keynote
Free on every Mac and pleasant to use. They import Office files and export back, so complex formatting can change.
FileHop
A free file browser that also edits .docx, .xlsx and .pptx files. It's best for quick fixes to real files, and it can review tracked changes but not create them.
