Microsoft's announcement sheds light on how the back-end work manifests to the user when its apps are initially launched:Īre there any performance considerations for running Office under Rosetta 2 translation? Instead, the Rosetta 2 translation process happens entirely on first launch, though there is a slight performance hit as the initial x86–64 translation of instructions takes place.

In contrast to OG Rosetta – the version that allowed PowerPC apps to run on Intel-based Macs – code isn't interpreted in real-time. Thanks to Apple's Rosetta 2 translation software, Apple's M1-powered Macs can run x86-64 code that's written for Intel Macs. This means the latest release of apps including Word, Excel, PowerPoint, Outlook, OneNote, and OneDrive can be installed and run on Apple's latest 13-inch MacBook Air, 13-inch MacBook Pro, and Mac mini using Appel's Rosetta 2 translation layer. Following Apple's unveiling this week of M1-powered Macs, Microsoft has released a new version of its Mac Office 2019 for Mac that includes support for macOS Big Sur and compatibility with Apple Silicon machines.
