OpenOffice can associate open file formats with file formats designed under the Microsoft Office suite. Office 2019 and the upcoming Office 2021 are single-device products that are purchased with a one-time payment. One of these applications is OpenOffice Suite, which is a good replacement for infrequently updated Microsoft Office for Mac, and the best thing is that it’s completely free. macOS Support The current Apache OpenOffice supports Apple OS X version 10.7 (Lion), 10.8 (Mountain Lion), 10.9 (Mavericks), 10.10 (Yosemite), 10.11 (El Capitan) and macOS 10.12 (Sierra), 10.13 (High Sierra), 10.14 (Mojave), 10.15 (Catalina).
