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

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.

I have tested Apple's magic mouse, Apple's magic trackpad and two wired mice from Logitech. The problem occurs with all of these devices. It doesn't matter whether they are connected via Bluetooth or cable. So it's not the devices' fault, it must be a software problem for which Apple is responsible.

I seem to be able to remedy the problem by putting the mac to sleep and waking it back up.

Please try what I wrote. Go to mouse settings and turn off all options also further setting options. Turn them off and on or on and off. After I did this my mouse working goog.

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 :)

Glad that you got it working.

Only, how come Safari interfere with/how Magic Mouse work? Can you give more insight on that? Thanks.

Macbook Pro M1 14inch. I just updated to Sonoma 14.4.1 (23E224) and the issue is still persistent. In fact, it seems to be worse now. Before it was somewhat intermittent but now its almost too difficult to use the mouse to do normal functions, much less any video / photo work, illustrating, or anything requiring precise mouse movements.

I move my mouse as a test, lets say from one side of my screen to the other. About 1/4 to 1/3 of the way across the screen and all of the sudden it lags or stops mid movement. The cursor then reappears on the other side of the screen.

The issue is not only happening on my Magic Mouse, but also on my Logitech M720 Triathlon mouse. This would automatically rule out any possibly of the problem being a dirty mouse sensor. Any mouse device connected via bluetooth exhibits this issue.

All suggested fixes have been attempted. This is a software issue as all have stated previously. Not a hardware or user issue.

I am also noticing a slight lag in the connectivity of my bluetooth keyboard. If I let it rest for a few minutes, the first few keystrokes do not register or they lag.

At this point the computer is unusable as a desktop device and I am forced to use it as a laptop, causing productivity loss and potential lost wages. We expect a resolution immediately.

Terrible Apple Support Again!!!!!!!!!!!

Being a long time user of Mac hardware this issues comes up after every new release of MacOs. Every time there is the standard reply stating this is to do with dust on the sensor..... At which point is someone going to own up to the fact that these issues repeatedly exist???? it normally takes a few updates to be released to get a resolution to the issue...!

Please Please stop trying to push the issue to user error!! Apple you need to own it and solve it!!!

The one thing that always seems to be a common factor is that it occurs when using Safari with high memory using pages... It is specific to Mouse and not bluetooth as when using an external touch pad connected at the same time to the same bluetooth connection as the mouse the touch pad works fine!!! but the mouse has Issues... This is the very reason why I own a bluetooth touch pad as well as a mouse.

Seems more like a bug fix is needed. This problem didn't occur until upgrading to Sonoma. I have two Logitech M585s that had no problems until the upgrade. Regardless of what other software was running, whether Photoshop or Safari etc. It's not just a 'time to clean the mouse' issue. I have times where the mouse won't unclick selected items and I have to restart. I didn't cause the problem, Apple needs to fix it.

Fact - The issue never existed in the Beta Program... It only appeared in Live!!!

Fact -The very same thing happened with previous OS releases!!

Fact -This is not a USER issue!!!

Fact - There is nothing wrong with Peoples Mouse Or Touch pad

Fact - There is an Issue with the Production version of the OS with regards to Bluetooth connectivity under certain circumstances.

Fact IF you buy a new Mac right now you get a version of the new OS with has this Issue!! BUT if you don't upgrade your current OS on a stable system you will not have the issue.

Fact - you are entitled to your own opinion, but thankfully that will not change the FACTS.

Well, I never had any issue like that until my update to Sonoma. Got the same behavior since the first release 14.0. I'm currently on 14.1 and getting the issue mostly when using some heavy tasks (XCode+Preview and/or Simulator or anything that requires GPU to render graphics in 3D.

Btw I have multiple devices at home (3xMacBook, 1xiMac + 1xMacMini) and experiencing it only on my MacMini-M1 (the only one running Sonoma).

I have not had any issue for quite awhile now on M1 pro running Sonomo 14.4-5 - until I try to play any movie in quicktime while laptop is connected to external monitor. Almost immediate lockup. Sometimes if I immediately disconnect the external monitor, I can get mouse control back (Logitech M585 - don't judge me, I like 'em). Otherwise usually have to do a restart. So I thought at the time I had discovered that it has something to do with external monitors, until my mouse locked up while monitor was disconnected, playing a QT movie. Thought I saw a post somewhere suggesting quicktime acceleration w/mouse was possible source of conflict.

EDIT: by the way, can play movies using VLC all day without lockup.

Never had a problem though until Sonoma upgrade.

Try resetting your Magic Mouse.

Just reset the Magic Mouse.

This is not a mouse/trackpad issue. I just updated to Sonoma on my MacBookPro and it happens on the bluetooth mouse and track pad. It's an OS issue. Very frustrating.
