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 presentįacing 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.Ĭheck 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?Īlso, 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.Īlso, 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).
