I suspect something in the bluetooth protocol is prone to something like interference and that maybe when you re-associate a pointer device you get a new channel or something is reset that makes this behavior go away. It helped that I was using a trackpad because it made it clear this wasn't a mechanical issue. In my case the cursor hanging immediately stopped as soon as I paired my trackpad once again.

Re-associate it and try to see if the sporadic mouse hanging still occurs.

Click on the circled x icon next to your mouse to remove it (disassociate).

Go to Bluetooth system preferences pane.

I frequently run into this issue, go through SMC/NVRAM reset (although it should no longer be necessary on my M1 Mac), disconnect all my external peripherals and drives, boot in Safe Mode and run Disk Utility Repair on the Macintosh HD, and all that's been described in other answers until today when I finally did the simplest thing and this issue went away: Since there's no top level answer that mentions this. (Also, there is an ambience LED in my mouse which I cannot control in macOS). Maybe there is a power issue - where the mouse is fluctuating b/w 100mA and 500mA.

Further, when the ipad is connected as a display over USB, macbook's fans are on.

It makes me believe that the mouse gets briefly disconnected from the OS.

If I look closely, sometimes when the mouse freezes and unfreezes, the scrollbar on the side of chrome gets a re-rendering.

Not able to fool it: Disconnecting ipad immediately brings back the issue.Also does not occur when all three screens are connected (incl ipad).Does not occur when I use an iPad as a second screen.

I use this software to use iPad as a second screen - Duet Display.

For the pause part - buttons and scroll wheel of the mouse are also down.

Further, I also use bootcamp (win 10) on the same mac - does not occur in windows at all - same hardware.

Happens when a second screen is connected (Second screen tried in different refresh rates over HDMI - 60/120 Hz).

That split second pause of the mouse is driving me crazy.

Try restoring just your user account using Migration Assistant once your Mac is in a clean state and you have confirmed the cursor issue is not presentР В РІР‚СњР В РІР‚РЋacing the same issue on Mac OS Catalina on (macbook pro 15', 2018) with a RedGear Manta USB gaming mouse. If you find that the cursor isn't skipping then the issue may be due to an Application previously installed on your Mac or a corrupt system file.

Once you have a good backup you can also try restoring your system to a clean state and re-test without your restoring your data on the Mac. Try creating yourself a new user account to test in, if you find the cursor is not skipping in the new account it may be an issue with your user account. If your hard drive's health isn't great then you should backup your data with Time Machine ( ) and take your Mac to an Apple Store or Authorised Repairer for servicing so they can replace your hard drive. Once you have done this and are in Safe Boot mode, reboot the Mac and try using it normally again, see if the issue is resolved.Р В РІР‚СњР вЂ™Р’В¬heck your hard drive's health using a tool such as Drive Genius, disclaimer: I do not work for them but only recommend their tool as its quite easy to use and understand. You can also try loading your Mac into Safe Boot Mode to force the Mac to check and fix its startup volume from any issues it may have ( ). You can also get this upgraded on most Macs. If so, perhaps see if your Mac can have its Memory upgraded?Р В РІР‚СњР В РІР‚С›lso, Go to the Disk tab and check Data written/sec: If you're looking at 50 MB/s or above and your Mac does not have an SSD then that's most likely the issue. If so, close all running Applications and check again.Р В РІР‚СњР В РІР‚С›lso, with all your normal applications open check the Memory tab and see if Memory Used is close to or exceeding Physical Memory. Try leaving Activity Monitor open and check if CPU usage remains consistently high while you are doing your usual tasks. Here is a comprehensive list of things to try: I've had that happen to my own Mac and typically for me it was due to a high system load or something else locking the system (like a hard drive failing for example).
