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

Hello Sudeeshn,

Thanks for providing us with those additional details. You've done a great job isolating the issue. To ensure that we're covering all of our bases, we also suggest completing the following steps:

"Clean the sensor

Find the sensor on the bottom of the Magic Mouse, then use compressed air to spray the sensor or use a cloth to wipe the sensor. If you use compressed air, do not invert the air can while you're spraying.

Check track mouse settings

In System Settings, you can change mouse tracking, double-click, and scrolling speed.

Check for interference

Learn how to resolve Bluetooth issues caused by wireless interference."

More details here: How to keep your Magic Mouse tracking smoothly

If the issue persists, we suggest that you reach out to Apple for further assistance. You can follow this resource to connect with them: Get Support

Take care.

I had the same problem with my 2023 MacBook Pro.

The problem arises when you plug too many things into the USB C ports. In my case, it was an external monitor plugged in through a dongle. Once i removed that USB C connection - and plugged it in through the HDMI port instead, all the mice worked fine and still do.

I also have this issue. Some additional info:

• this is a _cursor display_ issue, not a _cursor position_ issue. If you go to some website or some UI that has on mouse hover behaviour, like a button highlighting, you'll see that even though the cursor seems stationary on the screen, the hover behaviours show you where the _real_ cursor position is. It's moving just fine, but the visual indicator of the position isn't updating
• I use fast user switching, and the cursor can be smooth on one user but broken on another. It doesn't seem like there's any consistency over which one is working and which one is broken
• It seems pretty clearly related to an external monitor — unplugging it always fixes the problem
• Turning off mouse cursor acceleration did nothing to solve the issue
• Turning off animated wallpaper did nothing to solve the issue
• Turning off the "share cursor between nearby Macs/iPads" and all the related nonsense in that menu did not solve the issue
• This started happening with an upgrade to Sonoma

This worked on my MacBook Pro M2 Sonoma 14.5 16 inch 2023:

I gone to mouse settings. There I turned off "Smart Zoom" and "Pointer Acceleration (Advanced)".

That worked for me.

After tried turning back on, all worked fine.

Make sure the Magic Mouse is connected to Bluetooth to you Mac, then turn off your Magic Mouse. Now, turn on the Magic Mouse while pressing down on the left button (click button). This will clear the connectivity history of your Magic Mouse. I read this somewhere. I also put the Magic Mouse off at night.

Try going into the Settings > Displays > Advanced.

Then turn off "allow your pointer or keyboard to move between any nearby Mac or iPad".

I hope this helps. This solved it for us. Good luck!

Thanks for this advice. I had tried everything and all it needed was a good clean

I used my glasses cloth worked a treat

OK I had the same issue which started when I had turned night shift on in Display settings. As soon as I switch back, the mouse issue went away. This might be a differnt issue but if you have night shift switched on, just try turning it off

update: while I have not had issues while browsing/photoshop in the last few months, I can no longer use quicktime or will lose mouse control, and my m1 pro macbook pro hangs entirely or becomes sluggish until I force quit quicktime (which also happens in a most sluggish fashion). So my 'fix' is to not use Quicktime to watch videos and use VLC instead WITH NO ISSUES. No I don't want to reinstall the OS and hope that works, no I don't want to jump thru hoops because Sonoma broke something and Apple is reluctant or doesn't yet know how to fix the issue. But it sure seems like a 'it just works' problem that Apple should fix on its end, not have me troubleshoot and root around for an answer.

I had a similar issue and cleaning the sensor fixed it, thank you!

Seems like safari was causing the issue for me in many cases.

I'm deprioritizing the process using the command below:

So far so good :)

>>It seems pretty clearly related to an external monitor — unplugging it always fixes the problem

I have the problem with an iMac and no external monitor. Upgrading to 14.4 helped for about an hour. (Logitech mouse)

I also had quicktime movies locking up my system since upgrading to Sonoma. Here's my next question - how many of those here are connected to an external monitor? I disconnected mine and the quicktime/mouse lockup disappeared. Is there some conflict between external monitors and mice with the update to Sonoma? I did not have the quicktime problem before upgrading... I have an Asus monitor.

If different mice from different manufacturers (whether with cable or BT), Apple's own mouse and its own trackpad all show the same problem, it can hardly be due to the hardware, but must be a problem in the operating system. And the way I see it, it has to do with external monitors.

I have now tested several mice, several drivers and Apple's Magic Mouse and trackpad. The problem always occurs when more than one monitor is connected to the Mac Studio and these monitors are mirrored. The problem first occurred with Sonoma.

Even my old iMac from 2009, which can actually only control one external monitor, but on which I used two external monitors via Display Link, was able to display a smooth mouse pointer.

Apple always has a big mouth when it comes to advertising the "most advanced operating system ever", but is apparently unable to fix even a simple problem like a lagging mouse pointer.
