OpenOffice
Apache OpenOffice is a free, open-source office productivity suite that includes Writer for word processing, Calc for spreadsheets, Impress for presentations, Draw for illustrations, Base for databases, and Math for equation editing. It is designed to be compatible with Microsoft Office file formats and has been in development for over twenty years. OpenOffice is maintained by the Apache Software Foundation, supported by a global community of volunteers, and can be downloaded and used entirely free of charge for any purpose — personal, educational, governmental, or commercial.

1 suggestionApache OpenOffice does not yet have a native Apple Silicon build. The current latest version (4.1.16) is Intel-only and runs under Rosetta 2 emulation on M-series Macs. The project is still actively maintained with periodic bug fixes and security updates, but there is no announced timeline for native Apple Silicon support. Since Rosetta 2 will be removed in macOS 28 (September 2028), the Intel-only OpenOffice will stop launching on that release. If you rely on OpenOffice, monitor the official openoffice.org website for announcements of an Apple Silicon build, or consider switching to LibreOffice, a maintained fork of OpenOffice that already ships a native arm64 build for M-series Macs. LibreOffice preserves OpenOffice's free and open-source philosophy and can open and save the same file formats, making the transition straightforward.
