Mouse lag Big Sur

For everyone having mouse lag issues, I would update to the most recent mac os Beta version. I did this, and all the lag disappeared. The only issue I have is if I am running multiple high CPU apps then I notice a difference.

After searching and searching for fixes for this issue, this is what worked for me.

I had previously used this to increase the mouse speed beyond what the system would allow. The update to Big Sur had reset this speed setting and I wondered if it would fix the issue. Thankfully, for me at least, it did.

FYI I have a setting of 15.

Good luck.

I have the SAME problem with the mouse that came with my new 2020 iMac. It not only lags on the dock but ,out of the blue , it general it will slow down . Sometimes the pointer will turn into a LARGE arrow while moving around..Any answers will be appreciated .

I'm having the same problem since the last update. My Magic Mouse starts to lag at the same time every day and I have to restart my computer. I had the same problem with my track pad...it lagged too.

There still isn't a fix for this yet. I'm using an MX Master 3, fully up to date, and the glitching and lag is still really prevalent. Also it doesn't matter what I'm connected to: Logitech Unifying Dongle to computer, Unifying Dongle to Tbt3 hub, Mouse to Computer Bluetooth— nothing works.

I've tried deleting plists, resetting the Bluetooth settings on the Mac, adjusting the speed in sysprefs... Pretty much everything in all the threads here, and nothing fixes it. The MX Master 3 cannot adjust its polling rate in any Logitech or Apple app, so that also isn't an option.

This seems like this is a major frigging issue amongst MANY in the very BROKEN Big Sur, and I'm VERY tempted to revert back to Catalina as this is my WORK laptop and this "bug" is killing my progress.

I've done what I can by posting here and sending a bug report, but I guess we need for Apple to get off their fat TRILLION DOLLAR DUFFS and push a fix. I can't BELIEVE that no one AT APPLE is having this issue. It's like they don't even test out their own products, because I don't even understand how it even got out the door being this broken, but it's unlike Apple to really care about quality control, so I shouldn't be surprised.

Hi there, I suffer from the same issue for months, but I never have this kind of problem in the parental macOS, I did cross-check by using my mice on Mac Pro, which worked fine and perfect. So, I am sure it's the matter of Big Sur.

I asked the Apple assistant for help, and neither reset of SMC and NVRAM, nor safety boot work. I tried for several times, but the results were the same and the problem was still there.

Recently more users have a similar problem as us, then I asked the Apple assistant again, they found the right answer:

1 > System Preferences> Bluetooth.

2 > Checking the SHOW Bluetooth IN THE MENE BAR;

3 > Press Option + Shift, then click on the Bluetooth button; You will get the following

>> Reset the Bluetooth Module.

>>Factory reset all...

The Apple assistant suggests Resetting the first one, I did the first two.

The mice and keyboard work fine and dont lag any more.

Things have gotten slightly better since this post started, but it STILL feel laggy to me when I run 1000hz with my Logitech G Pro on my MacBook Pro 2019. Ended up going down to 500hz, then back to 125hz. Was very noticable running Stadia in Chrome.

Hey @apple when is this going to be REALLY fixed? Ran much better with Catalina.

This is still happening! I've replaced the mouse with a new Apple one. I've tried my Track Pad. Nothing helps. It locks up at least once a day and I have to restart my computer to get it to start moving again. This is killing my productivity with working from home. Apple really needs to fix this. It makes my computer useless when it's locked up and it's not always a good time for me to restart it and get back to where I was when the mouse stopped working.

Hey! I have this problem and I am using a mouse with the software for which that I cannot access. I have a Model O Glorious. If you find a way to change the weird sort of smoothness in the mouse on Bigsur please let me know as I am very frustrated with this.

i commented on your video. I have the same problem. Ugh!

Yes. I have this problem, when I was playing minecraft, my mamba wireless mouse was laggy, but the trackpad worked smooth. I hope apple responds and tells us how to fix this issue.

I have the same issue with Razer Atheris, but in BT mode I don't have those lags.

Do you think apple will view this or even fix it in the next 2 weeks or so
