macOS Monterey 12.0.1 & Magic Mouse / Calendar Issues

Hi this is driving me crazy, I cannot get my mouse to scroll or now double click which is debilitating. I have tried everything including everything the Apple support got me to do in 2 calls over 2 days. The preference pane won't load for the mouse, bluetooth, accessibility and Siri. Bluetooth is showing as off although my keyboard works as well as the magic mouse pointer and single click. This is definitely a Monterey issue, never had an issue before.

This also replicates on another user account we set up to test so definitely a software issue with the system. Only thing apple support or mac self help say that I can't do is the bluetooth module reset it won't show on my system in any way.

Apple please sort this out quickly I am working with spreadsheets and without the scroll and double click this is causing me a real challenge!

I am on a 2020 27" iMac (intel) with a Magic Mouse on Monterey, with constantly lost connections.

I now completely recharged the mouse, and it seems fine (for the time being). On 48% before, it was unusable, and started sticking, or barely scrolling every few minutes, no matter what re-set I tried.

I have the exact same issue and it is driving me crazy...

I have a Magic Trackpad as well so I can turn off Bluetooth and turn it on to reconnect my Magic Mouse.

But even when I turn Bluetooth back on my MacBook just won't reconnect with the Magic Mouse and it takes a couple of tries to get the mouse working again. never experienced something like this with an apple device before.

I have a 2020 M1 Mac Mini and am having similar issues with my Magic Mouse and Magic Keyboard after upgrading to Monterey. When my I try to login in from sleep, the mouse is frozen and the keyboard is non-responsive, except for the "ESC" key which seems to take me out of login. Then when I click my mouse again, everything seems to respond. I opened a case with Apple and they had me edit the Bluetooth plist....did not work....then they had me do a clean reinstall...ALSO DID NOT WORK...I even purchased a Logitech 2.4 wireless keyboard and mouse to test and was having similar issues with other input devices.....I agree Apple needs to fix this ASAP. This is so annoying and frustrating.

Yes I have the exact same issue since upgrading my 2020 m1 macbook pro to MacOS Monterey, but it gets worse!

my magic mouse loses it's gestures and i need to power it off and back on, it also gets jumpy sometimes! (it doesn't move smoothly on the screen! it get's stuck for half a second and jumps somewhere else!)

i don't have this issue with other mouses (mice?)

also my airpods pro can't connect to my mac sometimes. I'm assuming there is a bigger problem in the software side with bluetooth.

That's my problem exactly. It's intermittent. Began the first time I woke my Mac after updating to Monterey. Thank the cyber gods I kept an old corded mouse. It works just fine but feels clumsy now that I've gotten used to the Magic Mouse.

I have found a workaround, although I hope it is temporary and that Apple gets a fix out quickly. When I wake up my Mac (late 2015), the mouse is always non responsive now I immediately turn off Bluetooth and then the Magic Mouse. (I use an old, corded expanded keyboard, so I don't know if the one that shipped with the Mac is affected.) Next I pour myself a cup of coffee and then turn back on first bluetooth and then the mouse, which responds. It's an annoyance but minor and saves me the hassle of having to wait for a reboot to complete.

I have the same problem. I dowloaded the Monterey upgrade this past Saturday and my wireless Apple Mous has not been working since. In order to get it work, I have to uninstall it, restart my 2020 Macbook pro and reinstall the mouse. Once this is done, if I don't use my laptop for a about 30 minutes, I have to start all over again. I agree that upgrades are needed but they should ensure that fixing a few issues doesn't mean other features will stop working. I am not happy at all. I work for a Title Agency all day long at the office and must login remotely in the evening on my laptop.....without the mouse, it's impossible for me to work since using the track pad is not fast enough.

For myself, I can use the secondary click on any setting with magic mouse, I've 1 Space grey magic mouse 2 bought 2 months ago, 1 magic mouse 2 that came with my iMac 24'' M1 ( 4 days old ) and 1 Magic mouse 2 ) 1 years old. Work on magic track pad 2 or with simple cable mouse.

Yes same issue here. Been going back and forth with Apple support no resolution. Now they said bring computer to Apple store for diagnostics! So I purchased a Logitech mouse to see what would happen and guess what? Scrolls fine. Actually this new mouse is way better than the Apple mouse. It’s definitely an Apple issue not mine

Response to Jules Garfinkle. I thought I had fixed the problem. Worked through a complicated set of instructions I found online including deleting the plist. Worked great that day. The next day, after I woke up my Mac, same old same old. This problem is way beyond my pay grade.

Another development in the Great Magic Mouse Debacle with iOS 15: This morning when I woke my Mac, the mouse was again non responsive. I set it aside and used my old corded mouse but did not turn the wireless one off. About 30 minutes later I decided to check the battery level on the wireless mouse. I used the corded one and found the wireless battery was almost fully charged AND CONNECTED! I wiggled the Magic Mouse and had cursor movement back. Could it be that it just takes a long time to reestablish a Bluetooth connection and usability under iOS 15?

I had mentioned this problem with my MacBook Air M1 and Magic Mouse Model A1657 here some time ago. Specifically, the trackpad functions of the mouse stop working, while moving the cursor and clicking are fine. 

I have been dealing with the problem by hovering over the bluetooth icon at the top of the screen, turning the Magic Mouse OFF, then back ON, then enabling it with the mouse from the trackpad. This seems to work every time and doesn’t take very long.

However, I now have a new development to report. Several months ago, I had a problem with the screen turning pink and then crashing. I ran the M1 diagnostics and got the following result, "There may be an issue with the trackpad. Reference Code: NDR005, NDR006." Later, I read that the anti-virus software ClamXAV might be causing the Pink Screen crash, so I disabled it. No more crashes. Later I re-installed it and after awhile got another Pink Screen crash. So now it's gone.

However, I still have the trackpad diagnostic error. I was concerned about this, so I took the MacBook Air to the Genius Bar. They ran the diagnostic and found nothing. They kept it overnight and ran a complete series of tests with no problems (by the way the Magic Mouse was home on my desk - I did not even think there was a relationship). 

Tonight I ran the diagnostic again and again got the trackpad error. For the first time thinking that there was a connection to the  Magic Mouse problems, I turned the Mouse off and ran the diagnostic again with results that said, "No issues found. Reference Codes:ADP000."

I have repeated the diagnostic test several times. Magic Mouse on and connected gives trackpad errors. Magic Mouse off gives no errors. 

Hopefully others are correct and Apple will fix this soon.

I have documented my struggles with Monterey and the Magic Mouse here before, but now I have good news to report. Yesterday I got angry and instead of putting my Mac to sleep at the end of a frustrating work session, I shut it down. I didn't bother to unplug it, but I did shut it down. This morning when I restarted it, the process took longer than usual, but then everything, including the mouse, worked. Did Apple slip in a fix overnight? I don't pretend to understand, but I am grateful.

Upgraded to macOS Monterey 12.1 and it seems to have solved the issue with the Magic Mouse disconnecting every time my iMac woke up from Sleep. Had made at least 3 calls to Apple Support that didn't solve the problem, though they tried. I had told them each time it seemed it happened after I upgraded to Monterey 12.0.1, but they didn't appear to know there was a problem that many were having.

Had an appt. to take my iMac and new Magic Mouse in today, but found this discussion last night. Had not been alerted by auto alerts that an upgrade was available, but when I manually went to Software Update, there was an upgrade to Monterey 12.1 available. I did it (took quite a while) and voila--it seems to have solved the Mouse disconnect problem! Canceled my appt. to take it in. Here's hoping it continues to work properly!
