macOS Monterey 12.0.1 & Magic Mouse / Calendar Issues

Thanks, I will try this.

I have found that turning off bluetooth for a while and turning it back on reduced the frequency of these scrolling outages from every time the machine woke up to about twice in 4 days.

Yay, Mark! You found the bug and the fix. Albeit temporary. I upgraded to Monterey 12.0.1 overnight and was mortified that nothing would scroll. I'm actually on hold right now with Apple tech support and escalating this up to another tech. For now, I can be productive with the Magic Mouse. Turn OFF and ON the switch returns the scroll function to all programs and browsers.

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.

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.

A workaround would be to not sleep but just let the screensaver take over. SSDs don't need to sleep like rotational HDs do.

Report this on https://feedbackassistant.apple.com. Remember to include which Mac you are facing this issue on.

i have the same issue with my scroll on the magic mouse 2 (trackpad is fine), almost bought a new mouse. it seems like a bug with the new macOS monterey ; no issues opening my calendar tho - hope apple fixes this bug soon, it's quite annoying

In the last couple of days the scrolling with the Magic Mouse only failed once, requiring me to turn it off and on again. Before I reset the Mac's bluetooth, it failed every time the machine went to sleep. This is progress, though it should never happen.

I have this problem too. I thought my mouse is not working. After upgrading to MACOS MONTEREY on M1 MACBOOK. I have to disconnect bluetooth mouse and reconnect it back on before I can use the scrolling. So annoying sometimes but Hopefully they have some updates soon.

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 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.

My Magic Mouse is behaving as it should more often now, but now always. Too often I have to use my old corded mouse to disconnect Bluetooth, turn off the mouse, turn Bluetooth back on, and turn the mouse back on. So far this has solved the problem and is only a minor annoyance, but it is an annoyance. Apple prides itself on perfection. They can do better.

I have 7 Mac Pro's (the professional unit that people say looks like a cheese grater) at work and they all have the same mouse stutter, or the loss of movement left and right. I had a mouse replaced for one of the units. The problem is still there. I also own a 2 week old iMac (24", M1) that is also having the same issue. All computers are running the most current OS available from Apple. If 8 units are having the same problem, even with a mouse exchange which would make 9 mice in total, and the fact that 2 different models are involved, 1 being a professional unit, it boils down to a software glitch. When video editing is on a deadline, this mouse issue is truly problematic. It was also discovered that with the OS updates, both the Mac Pro's and the iMac will not eject and release a G-Technology external hard drive using a Thunderbolt 3 connection. Seagate drives do not have this problem. To release the drives you must either log out of your account or totally shut down the computer....another time waster. Apple, PLEASE, find the solutions.

My fix of turning off Bluetooth and turning it back on again is not a complete fix. Usually, scrolling survives the machine going to sleep but not always.
