How to fix randomly stuck Magic Mouse after Sonoma M1 Pro update

OK, so external monitor detached doesn't remove the problem. Display options suggestions doesn't solve the problem . . . back to square one.

Upgraded to 14.4. Things were looking good for a few days, but today the problem is back.

Thanks, I guess it did start happening once I switched to an external monitor which also powers my macbook through only one usb-c cable

I just did this (turned off and on while pressing left-click button) on a Magic Mouse that was tracking erratically and it seems to have fixed the issue! Thank you!

Please do not make it a hardware problem. Tried three different mouses including a wired one that works perfectly fine on two other devices. The issue is Sonoma.

it will work just for a couple of hours... but agree it's something related to pointer acceleration. also noted that multiple screens makes this issue worse.

for me it works fine. not only for a couple of hours.

of course maybe it is individual depending on configuration, software usage and so on ...

Same issue. Have you solved it?

I too have had the mouse pausing 3 to 5 seconds as it moves, since the upgrade to Sonoma 14.1. Just to be to double check that it wasn't a mouse, I swapped the mouse out with a 3rd party wireless mouse. I then tried a wired optical mouse just to rule out the mouse. Same "sticK occurs. Since it was a clean boot install where I wiped the drive and used Time Machine to restore, I created an entirely new boot USB thinking it may have been a poor boot image creation. When that one showed the same results, I created one via SSD and USB-C enclosure drive. I was thinking something may have occurred due to poor performence of data transfer. Once my 27" iMac 2019 boots into Sonoma, the mouse hangs or sticks as its moved. The only time I don't see it "stick" is when the mac is booted in recovery mode with no association under the Sonoma OS. As soon as you have the option to install Sonoma, the mouse hangs. This occurs long before the OS install. It is booted under Sonoma boot OS so the same bug appears. I booted back into into Ventura with another boot USB and the problem disappears. I am a believer in Apple and believe in getting all the facts to resolve a problem. I am also a believer in being proactive. Bugs like this are not intentional but this one is definitely an issue. I hope I helped.

I have the same problems. I work with adobe programs and after upgrade to Sonoma from Ventura I have problems with my magic mouse.
