I updated to MacOS Catalina and now I cannot share my app screens. I can share my desktop, but that is all others can see.

Found it.

System Preferences

Security & Privacy

Privacy

Screen Recording

My system had an entry (unchecked) for Microsoft teams. I think it asked me as I was launching but I blew by it. Not sure how you'd add it if it's not there. You just have to turn it on, and Teams screen sharing will work.

    I have Catalina as well and this WAS working yesterday. This morning, Teams was updated to 1.2.00.28258 and now I can no longer share my screen. It could also be related to the MacOS update that happened yesterday. The preference box is checked in the panel; I have checked and un-checked it, rebooted, etc. and still Teams is sure that it does not have permissions to share.

    I have the same issue.  I found that a workaround is to not have Team app window maximized.   I'm hoping for a full fix but the workaround seems to work for me.

    The above did not help me with my problem. I did find a good workaround though... I think....

    First, why didn't the above answer help? My system was already configured to Allow screen recording in Security & Privacy settings. I didn't have any luck with tracking the problem down internally (I heard it's actually an issue with MacOS but that's not confirmed).

    To get screen sharing to work, here is what I did:

    1. Quit Teams
    2. Disable/Disallow/Uncheck 'Screen Recording' for Microsoft Teams in 'Settings -> Security & Privacy'
    3. Open Teams
    4. Start a Meeting (confirmed that Screen Sharing is not available)
    5. Quit Teams
    6. Re-Enable/Allow/Check 'Screen Recording' for Microsoft Teams in 'Settings -> Security & Privacy'
    7. Open Teams
    8. Start a Meeting (confirm that Screen Sharing IS now available)

    It stinks and who knows how long it lasts but it's something.

    I found the culprit on mine.  The To Do app from Microsoft can't be open when I try to share my screen.  I close it, and I can share my screen.  As soon as I have To Do running, it won't work.

    I have found that Microsoft To Do for MacOS is causing the problem for me. If To Do is open then I cannot share desktop in Teams. Closing To Do and magic, I can share desktop in Teams without being prompted to change security settings.

    It seems strange to me that there are such a wide selection of apps causing this issue with no apparent commonality. What is common between Cisco AnyConnect VPN, Sonos and Microsoft To Do?

    Anyway, for now I know I can just close To Do and it will work....but there has to be a better solution.
