Mac User's System Freezes when Sharing Screen


I have a Mac user that has recently started to experience a system slowdown to the point of freezing when sharing their screen in Zoom.  The user said that it only happens when sharing their screen in Zoom & that the rest of the time their system performs just fine.  We've already tried a general uninstall/reinstall of Zoom and checking for updates with the reinstall, and the user's tried unchecking the advanced share screen setting: "User hardware acceleration to optimize video sharing". 


I've read in forum posts that potentially checking the advanced share screen setting "Use TCP connection for screen sharing" is helpful, but I'm not sure what, if any, downsides that could cause. 


We've also reset the user's NVRAM.  


Does anyone have any other ideas that we could try to speed up the user's experience of Zoom while sharing their screen?  I'm including the system specs below.


System info:

MacBook Pro (15-inch, 2018)

Processor Speed: 2.30 GHz

Processor Type: 8-Core Intel Core i9

RAM: 32.0 GB

OS: Monterey 12.6.1




Hi Rachel,

Part of resetting the NVRAM is to restart the computer.  So no restarting the computer did not help.


Hi @--AIM-- just checking in! Are you still facing this issue? If so, would love to further troubleshoot with you! Have you updated your Zoom client recently? If not, I would first suggest Updating Zoom to the latest version to see if that helps resolve your issue.
