I never experienced these issues before Big Sur. Today, less than a week since the Repair, the mouse has started stuttering again.

Then last week, out of the blue, the keyboard completely froze, the entire mac locked up, and after a few seconds, rebooted.Īfter booting into Recovery Mode and doing a Disk Utility Repair Disk on all the disks, it was fixed! So it seemed. This fix would last for a few days (less than a week). It took me a while to upgrade to Big Sur, but when I eventually did, it did not take too long for me to notice a mouse lag, as well as keyboard lag.Ī post suggested that if the following files be deleted, that would be the end of itĬom.plistĬom.plistĪfter deleting the files and rebooting the machine, things were okay again. I have a 2019 iMac with an 8 core Intel i9 processor, and 128Gb of RAM, with a Bluetooth Trackpad, Mouse and Keyboard. Ongoing mouse and keyboard stutter since upgrading to Big Sur Hello everyone

Big Sur 11.4, BUT - the issue has been happening since before I installed Big Sur.ĭoes anyone have any ideas on how to troubleshoot?.

Most of the stuff I'm running when the issue occurs runs fine on an old MacBook Pro 2017, so a high end Mac Pro 2019 shouldn't have any issues with the workload.

I have noticed something weird about the trackpad - even at 100% it often doesn't immediately connect to the Mac, and it has had very hard time reading multi finger motions recently - after I try them a few times, it seems to 'come back' to normal and works just fine. When the freeze occurs, neither device is able to move the cursor.

I have both the magic mouse and trackpad.

First Aid in Disk Utility hasn't found any errors.

Restarting the Mac helps 100% of the time but the issue comes back, sometimes shortly after and sometimes a day or two later.

I usually have at least Ableton Live, Chrome, Spotify, Splice, and a few other small things running. However, even though I tested this after closing open applications and the issue was still present, I can't say for sure that a specific previously open application doesn't cause the issue to start.

I haven't been able to identify if any application is the cause of this it seems to happen with nothing else running and nothing particularly strange taking place in Activity Monitor.

Details that might be relevant in my case: I saw other posts on this, but they appear related to a specific application, low computer specs vis a vis workload, or hard drive failures. The cursor on my Mac Pro 2019 freezes at irregular intervals for a few seconds at a time.
