Microsoft Ergonomic Keyboard stopped connecting to iMac on macOS Big Sur 11.7.10

Perhaps contact Microsoft about the possibility of Firmware Update for

your Microsoft branded wireless bluetooth keyboard; might be an idea.

Other than this idea, maybe try to see if some other for Older macOS

might be available, as minor steps could be out there worth a look?

(Just got done and am updating 'unsent reply' saved in browser, now)

A newer revised driver or firmware from Microsoft for their

keyboard could be about the only hope for a software cure.

Idea I didn't have time for, involves Rapid Security Updates for Apple

About Rapid Security Responses for iOS, iPadOS, and macOS - Apple Support

While that's long stretch; and I don't see that happening; at least by me.

[This did not contain older version access.]

While an extensive look-see in SW backlog, further

inside, I found SAME Update for macOS, your Big Sur is:

macOS Big Sur 11.7.10 • macOS Big Sur • 11 Sep 2023

Having spent 'some time' looking through by dates, iDon't

see a Niche update Step; while something may be hidden.

I'm hoping the thread here has not timed-out (typo fixes)
