Office empowers everyone to achieve more on any device. And Office loves Mac. We’re committed to delivering the power and simplicity of Office in an experience designed specifically for Mac, and we continue to make significant investments in the platform. Today, we’re excited to announce that Office 365 is now available on the newly redesigned Mac App Store. With one click, Mac users can download the cloud-connected, always-up-to-date version of the Office suite—including full installs of Word, Excel, PowerPoint, Outlook, OneNote, and OneDrive.

Office 365 provides experiences tailored to the Mac and macOS, like Dark Mode, Continuity Camera, OneDrive Files on Demand, and Touch Bar support on the MacBook Pro. And it’s connected to the cloud, so you can access your content from any device, coauthor with anyone around the world in real-time, and use the power of artificial intelligence (AI) to create more impactful content with less effort. The result is an experience that is unmistakably Office but designed for Mac.

“We are excited to welcome Microsoft Office 365 to the all new Mac App Store in macOS Mojave. Apple and Microsoft have worked together to bring great Office productivity to Mac users from the very beginning. Now, with Office 365 on the Mac App Store, it’s easier than ever to get the latest and best version of Office 365 for Mac, iPad, and iPhone.”
—Phil Schiller, Apple’s senior vice president of Worldwide Marketing
