macOS Monterey 12.0.1 & Magic Mouse / Calendar Issues

My 12.1 was available as an update on my imac today in the Netherlands . Mouse problem solved . Hope you get it soon .

Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?

OK sometimes it helps to turn off your mouse, go to Bluetooth settings and remove the mouse from there then again set it up as a bluetooth mouse. If push comes to shove maybe even resetting the whole Bluetooth thing might work.

iMac 5K 2017 with Magic Mouse 2 and Magic Trackpad 2. Have on multiple occasions tried to wake my iMac with a click on the trackpad or hitting space on keyboard.. nothing. Hit the power button and it wakes right up but it doesn't recognize the trackpad or keyboard. I have to plug a lightning cable into each device to use them but as soon as I disconnect the cable they stop working which means the bluetooth is not connected. Turning bluetooth off and on usually fixes it.

Very annoying and a seemingly completely avoidable bug given that these are genuine Apple peripherals. What happened in the beta testing????

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.

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.

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.

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.

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.

I called Apple Support on Thursday because my Magic Mouse was really being uncooperative. It would either slow down or stop moving the cursor left and right. Deleting preferences only lasted a few moments. Oddly enough, blowing into the hole on the underside of the mouse, where the infrared sensor is, would also help for just a short period of time. Keep in mind that blowing air into this location is recommended, should it get dirty. But, my mouse is new, as is my iMac, so that isn't the case. So, after describing the issue to the Apple Support person, I was told that Apple is aware of a bug causing this problem that was introduced in the last update. It will be addressed in a future update but the support person didn't know if it would be addressed in Monterey 12.3 due to be out in another week or two or in a later update.

Turning bluetooth on and off again works for me too. Hopefully this is fixed in 12.0.2

Same problem on my MacBook Pro late 2016. Reconnecting the mouse with the lightning cable also solves the problem (until the next sleep)

I installed 12.1RC and the mouse scrolling problem seems to have been fixed.

To DebBucky (and others):

As noted by many others, this problem has been fixed for us with an upgrade to macOS Monterey version 12.1.

I have the same issue and it's driving me nuts. The scrolling comes back if I disconnect and reconnect it from Bluetooth but I do not want to have to do this every time my mac goes to sleep. Hopefully there will be a fix soon.
