Following Apple’s release of the M1-enabled Mac this week, Microsoft has released a new version of the Mac version of Mac Office 2019, which includes support for macOS Big Sur and compatibility with Apple Silicon machines.
This means that you can use Appel’s Rosetta 2 translation layer to install and run the latest versions of applications on Apple’s latest 13-inch MacBook Air, 13-inch MacBook Pro and Mac mini, including Word, Excel, PowerPoint, Outlook, OneNote and OneDrive.
Thanks to Apple’s Rosetta 2 translation software, Apple’s M1-driven Mac can run x86-64 code written for Intel Mac. Unlike OG Rosetta (which allows PowerPC applications to run on Intel-based Macs), the code is not interpreted in real time. Instead, the Rosetta 2 conversion process occurs entirely at the first boot, although performance will be slightly reduced when performing the initial x86-64 instruction conversion.
Microsoft’s announcement clarified how the back-end work was reflected to users when its application was initially launched:
Are there performance considerations for running Office under Rosetta 2 conversion?
The first launch of each Office application will take longer because the operating system must generate optimized code for the “Apple Silicon” processor. The user will notice that after this process is completed, the application “bounces” in the dock for about 20 seconds. The subsequent application launch will be quick.
Microsoft recommends that users install the November 2020 version (build 16.43) or later, which includes the latest optimizations for macOS 11 Big Sur. Eventually, this version will need to be replaced with the version introduced at WWDC in June 2020 that uses the new Universal 2 binary format.
Apple stated that Rosetta 2 is a temporary solution for developers to allow them to run existing Intel-based programs on Arm-based Macs, which means they will eventually need to create native applications for “Apple Silicon” computers . It is worth noting that Apple terminated support for OG Rosetta three years after its release.
Update: The original article incorrectly referred to this Office for Mac version as the “universal version”, but it is reported that this version is currently only available to users who registered through the Microsoft “Insider Fast” Beta channel, and has not yet received a final release date. .
