macOS Monterey 12.0.1 & Magic Mouse / Calendar Issues

I also upgraded to macOS Monterey 12.1 and the problem I had with losing scroll and gesture functions with my Magic Mouse has disappeared (so far). However, if I run diagnostics with the mouse connected I still get an error message, "There may be an issue with the trackpad. Reference Code: NDR005, NDR006." There is no error if I turn the mouse off before running diagnostics. I thought the error message was related to the loss of mouse functions, but apparently not...

Incidentally, like others I had trouble updating to 12.1 with my M1 MacBook Air. When I checked for an update, it told me I was up to date with 12.0.1. I had to boot into Recovery mode and reinstall the OS in order to get 12.1.

Same problem on Monterey 12.1 in Imac 24. Im loosing click abilities on my Imac every 2-5 minuts. Its not able to work.

Im seriously frustrated about quality. I want to return my money and get rip of this useless piece of crap - my work staying and I solving problems with mac.

Apple, you offer premium products, but your pc not working - who pay me this time? When will work me pc correctly?

I ve tryed this mouse with my macbook pro 2019 (big sur) and same problem with my iMac ( montaray). I spoke with apple support and they have suspicion about faulty magic mouse. So im going to service for warranty repair.

Ou, so they lied me on support. They told me, that dont have any report about this problem and they dont work about some software upgrade. They told, they are changing mouses only. Ive tryed one mouse on 2 pcs with diiferent OS - Big sur on macbook (Intel) and Montaray on iMac 24 (M1) and mouse has same problem on both macs.

I hope, there is some solution and change mouse will help, becouse magic mouse is from my new iMac.

Same issue as you have. MacAir 2020 M1.

Had the HD partioned with a test site........Monterey OS reinstalled. 12.0.1 and then 12.1 later...... the same mouse Issue persisted.

New logic board installed as it contains the Bluetooth tech..... but the Issue still persists.

Perhaps Apple people could please wake up and solve this issue. I've given up to 4 hrs a day for the last month trying to identify and solve the problem with Apple. Unfortunately they don't know how to fix it.

Disappointed that the Apple people seem to think I might be the only person in the whole wide world with this supposedly 'unique' magic mouse drop out ....... no one else in Apple seems to be aware of it or indeed how to fix it.

I continue to have problems with a dead Magic Mouse when I wake my Mac from Sleep, but I've discovered a reasonably quick workaround. I use my old corded mouse to turn off Blue Tooth. I manually turn off the Magic Mouse. I count to 10. I turn Blue Tooth Back on. I turn the Magic Mouse back on. I have been doing this for several days now, and every time it has worked. It's frustrating but not as much as having to reboot. I agree that Apple really dropped the ball on this one.

Thank You. Turning magic mouse on and off, or removing from Macair and then reinstalling will work - ditto turning the mac on or off......will reinstall the mouse and all its facilities. BUT only for some time. In general, it seems its about 24hrs or so before it drops out and misbehaves! 1st World problem, just not good enough from Apple.

Interesting, JR8s & LDVere, because 12.1 fixed it for me. (MacBook Air M1 and Magic Mouse).

As I mentioned previously, I still get diagnostic errors if the Mouse is connected - none if it's not. So I guess there is still a problem that Apple has not corrected.

Dec. 24, 2021: Same problem. It's quite annoying to have to turn Magic Mouse off and on again several times a day. Neither disconnecting Bluetooth, shutting down and restarting, nor various and choice cuss words have made a difference.

HEY, y'all at Apple, please figure out a fix and send it to us!

I wonder if the way that I upgraded to 12.1 had anything to do with it. Software Update kept saying my Mac was up to date with 12.01, so eventually I entered Recovery Mode and reinstalled macOS. Maybe that process got rid of something that was causing the Magic Mouse problem and that was the fix rather than 12.1 itself...

I assume you mean please learn to read. Where did you learn English? Well myself and many many other people have had the issue since the introduction on Monterey. However 12.1 solved the issue for the vast majority of people on here.

Sorry, english is not my primary language, but i understand, that 12.1 solve problem for SOME people. BUT i bought iMac 14 days later, upgraded to 12.1 and problems with MM is stil there and my new pc is uncontrollable.

And your solution - install 12.1....

Perhaps you might want to try entering Recovery Mode and reinstalling macOS. It's slightly different than just upgrading to 12.1 the normal way and maybe it would work (it did for me). Just a suggestion as I understand how upset and impatient people are about this issue. For me, it was getting so annoying, I would have tried anything.

Update on the Monterey update: 12.0 broke my Magic Mouse. 12.0.1 fixed it. 12.1 broke it again. My Mac does seem faster, but once again I have to turn off blue tooth, turn off the wireless mouse, turn blue tooth back on, and then turn the mouse back on. Not a big deal but also not up to Apple's level of excellence.
