Interesting to note the ‘macOS 10.14+’ in the article.

Attempting to update Office on a Mac actually running 10.14.6 gives a message saying ‘MacOS Upgrade Required - This update requires 10.15.0 or later’.

I am curious as to what Office now relies on in 10.15…

I recently bought the new MS office after getting a new MacBook Pro. However, when I tried to install it I was unable to log in to my MS account as MS has me locked out (for long time unused?). My trouble call to their phone trouble line resulted in a Trouble Ticket but nothing has happened in 5 days and I still can’t load and use my new software. Terrible Customer Service IMO.

“you can now disable the Rosetta emulator for Excel”. I wonder what this means… does it mean that this new version will automatically not use Rosetta on my M1 Mac, or do I need to do something that disables Rosetta for Excel? Maybe they mean that if Excel is the last app that needs Rosetta I can now disable Rosetta on my M1 Mac?

If your app is Intel-only, it will automatically be run via Rosetta (because there’s no other option). Similarly, if it is ARM-only, it will be run as native (again, because there’s no other option).

If your app is “universal”, meaning it contains both Intel and ARM code, you can choose which way you want to run it. Select the app in the Finder and do a “get info”. There is a checkbox, “Open using Rosetta”, which is used to configure it.

I assume that you’re seeing this message because the previous version was Intel-only and the new (current) version is universal. So you can now choose which way you want it to open. I am guessing that it has defaulted to Rosetta, because that’s what you were previously using (when the app was Intel-only), and the message is letting you know that you may want to switch it over to native operation (by un-checking that box on each Office app).

So why would you want to keep using Rosetta if the app is universal? Most of the time, you won’t. But if you are using a plugin/add-on that is only available as Intel code, then it won’t be available when the app is running natively - in which case, you can choose to run the Intel version (via Rosetta) and get access to your plugin.

On a MacBook Air M1 running macOS Big Sur 11.6.2, I am using Excel version 16.16.27 (201012) (and I have the other associated Office applications, but I rarely or never use the others). Excel is somewhat flaky, especially when using Conditional Formatting. If I install Microsoft Office for Mac 16.57, will that installation make the current installation no longer usable? I ask in case I find something in the new installation that is a deal-breaker for me. Thanks.
