Mouse Lag in Mac OS Monterey

Because the guys at Apple don't give a ****. They're more worried about not allowing comments to contain bad words or tinkering with new emojis.

Are there multiple monitors connected to your computer? If yes, try this: press cmd F1 and then cmd F1 again. cmd F1 mirrors the monitors, so both show the same content.

In my case the mouse works as it should after that.

@JMcGee2018, doesn't that keyboard come with a USB unifying receiver, so you don't necessarily have to use Bluetooth? My current work around for this issue is using an Apple wireless keyboard, which I run wired 95% of the time, which is obviously not an ergonomic keyboard ... when running in Bluetooth it has occasional hiccups and even as a developer, for me, it's easier to overlook that it'll fine, fine, fine ... entire word delayed, etc... The mouse side of things is totally unacceptable for me. So, on that front, I use a Logitech M720 triathlon mouse. In Bluetooth mode it's fairly useless. But using the unifying receiver it's really very good EXCEPT, my computer is remote from the mouse with an external monitor, so I have a usb extension to bring the receiver closer to the mouse and it works very well.

The receiver is on a usb extension to a hub and really has no issues.

Side note: reasonable to point out that if the ~2.4ghz receiver needs and extension wouldn't the Bluetooth (also ~2.4ghz) need an extension to work well? Maybe, but that's a separate issue as even if my mouse is any range from the computer it's still effectively useless due to these intermittent lag issues. I have tested that with this specific mouse and others when I'm on the go.

FWIW, in a very quick look I don't have an apple.com.bluetooth.plist as you mentioned but I do have:

• com.apple.driver.AppleBluetoothMultitouch.mouse.plist
• com.apple.driver.AppleBluetoothMultitouch.trackpad.plist

From when I was testing those.

This is happening to me on a wired mouse. I don't think this is Bluetooth related. It has to be something with the WindowServer. It's getting worse, at this time I'm just hoping that the new Mac Os Ventura doesn't come with this issue.

I just did another update and was shocked at how my system now runs like garbage. The mouse lagging at random times every few seconds is maddening. I am a graphic designer and build my own website for both my businesses- my team meeting this morning was a disaster as my system kept lagging, locking up, having Wi-Fi issues and of course, the mouse. I won’t be upgrading my other systems.. three mouse units (two magic and one USB) and it’s all garbage. I did a hard reset, reinstalled Monterey and ran Cleanmymac numerous times. I have taken my system to the bare minimum, disconnected all devices, Bluetooth and externals. Im going insane.

I've been having this problem since I purchased my iMac 27" brand new in January. I thought maybe it was the Magic Mouse that came with the computer, I bought a $100 Logitech mouse... still lags at random times. I just updated to Ventura, still a lag issue. It happens periodically, but it's really annoying and actually prevents me from being able to work.

I've spoken to Apple Tech Support a few times and I think our best recourse at this point is to make sure it's on Apples OS "radar".

Please complete the following to make sure it is.

Product Feedback - Apple

I had no problems with 12.4 but 12.5 has made my mac seem like a Jalopy. I have 2020 iMac, wired mouse, 96 GB memory with less then 30 GM used and mouse lag is terrible. I ran CleanMyMac X, rebooted and it seemed good for maybe 5 minutes and then back to the same lag. Hopefully they fix this as it should not be happening on this machine.

Let me add my voice to the choir. I have spent countless hours trying to fix this issue. The time I've wasted doing the tech support AND sitting waiting for my mouse to GET TO WORK is incredibly frustrating. There is quite clearly a QA issue in the Bluetooth stack or specifically in the mouse driver. (As @Brian0527 pointed out external track pads are unaffected by the issue).

Fingers crossed for an interim maintenance patch from Apple. (Please please please)

My mouse started acting up after my Monterey upgrade: unresponsive, slow, bouncing all over the screen — practically useless.

My fix was pretty puzzling: Stop using my mouse pad and place the mouse directly on my desk.

I can't explain it, but it seems to be a fix. My mouse pad was a solid matte black foam pad, which never gave me any mouse issues before the update. My desktop is a dark solid wood.

I have this problem as well. I've found ways around it, which are pretty frustrating, but only remembered it as an issue when I went back to an "old" computer running Catalina. The problem doesn't make a ton of sense to me, to be honest. Most of my mice are Logitech and a mix of bluetooth and 2.4ghz, with a usb receiver. What's odd is that there seem to be caches you can clear or removing the connection and rejoining - things along those lines that resolve the issue for a little while and then it will come back. Additionally, in the case of the 2.4ghz receivers you can make it so the receiver is essentially touching the mouse and it seems to be fine long term. A lot of this points to interference, i think, but what doesn't make sense is that the Catalina mac or this other mac with issues on Monterrey before the update didn't require any of these changes to work just fine in the same environments where the RF interference possibilities really shouldn't have changed all that much. It's baffling overall though, this has been an issue for a long time at this point and it doesn't seem like it's being addressed.

It's somewhat heartening to know I'm not the only person who has this problem. I'm running an older iMac 27" from mid-2017 and recently upgraded to Monterey (fresh install). The mouse lag is perplexing - it's like the mouse loses connection on a semi-regular basis. The Magic Trackpad works fine - consistent, as designed, but the Magic Mouse 2 for whatever reason is erratic as all get out. The hardware is all the same, the mousepad is the same, the only thing that has changed is the operating system.

In front of me is a brand new Mac Studio M1 with current Monterey. And of course it has the same problem.

However, my mouse is connected to the computer via cable and the problem does not occur constantly, but sporadically. It can be that there is nothing for several hours, then again the problem of the sluggish cursor occurs for several minutes, or even several times a day, so that you can not work properly.

And I'm pretty ****** that Apple doesn't seem to have done anything to fix the problem. You pay thousands of Euros for a new computer and then you can't work with it properly for a while. And I don't believe that such problems always only occur with the users. Don't the guys at Apple actually use Macs?

This is nuts and absolutely unacceptable. Where are the techs on this? I'm going to throw my MBP in a dumpster pretty quick here and get a Windows machine or Chromebook. It's affecting my work performance.

Not that this is a solution - but just what allowed me to forget about the issue for a while. I’m currently using the Logitech M720 Triathlon mouse, not with bluetooth but with the 2.4ghz wireless receiver and it seems to work well (lags on bluetooth). Many logitechs need pretty close proximity on the unifying receiver and have for years. this one isn’t very different, but i do enjoy stutter free mouse movements now… but have been traveling and using different bluetooth mice and forgot how bad this intermittent lag was. really thought it would’ve been addressed by now.

The problem has existed for several OS versions now. And each time, users have had hope that the problem will finally be addressed by Apple. And I don't think it will be fixed with Ventura. Apple is probably much more concerned with new emoticons.
