Microsoft has started rolling out new Universal versions of Microsoft 365 apps with native support for Apple Silicon and Intel-based Macs starting today. Outlook, Word, Excel, PowerPoint, and OneNote will be able to take full advantage of the boost in performance brought by the new M1 processors to the latest MacBook Air, 13-inch MacBook Pro, and Mac mini. Microsoft Teams app’s 115M daily active users will have to run it in Rosetta 2 emulation mode to get the update.
