Not able to share screen after catalina update

Well, I'll be ******. After trying all the various suggestions in this and other threads, I discovered that NOT being in full-screen is what made it possible for me to share my screen in Microsoft Teams. Just the opposite of jack's experience.

There was not an application blocking things for me. If I rebooted and started Teams as the first and only application, I got the error about needing the screen-recording privilege (which was already on). I also checked the firewall enable-incoming option, which was on.

This is a real bear of a problem. I wondered why it suddenly appeared; I thought it was some maintenance that was applied. But no; for me it was switching to full-screen mode.

I encountered this problem also and was initially stuck at the part where zoom is not appearing in the list of apps that request for screen recording permission. Make sure that your zoom is updated and also minimise your windows to check if zoom's permission request dialogs are hidden behind your windows. I have multiple zoom permission request hidden behind windows and not appearing. Once I click on one, the zoom app appear in the list of apps requesting permission.

I guess the quality control at Apple have been going downhill. Every update feel like it bring more problems and no benefits.

You need to upgrade to GoToMeeting version 10.2 or later; it has been updated for Catalina.

Hi.

Had the same issue of not being able to share screen via Google Meet.

Google Chrome already had permission to "Screen Recording" in Privacy settings.

For some reason when I close Adobe Creative Cloud it starts working again. If you have Adobe CC running, try to quit it. If not, try to see if closing any other app works.

Yes, THIS! I turned off a few running programs and eventually it worked again. Photos wasn't running but other apps were. Photoshop doesn't seem to be the culprit, could have been word, excel, acrobat. Just try closing out open applications and see if it starts working again.

I have found that with Teams and Webex inside Chrome that if I am running Full Screen mode, I am able to share the screen. If I switch to non-full-screen, then I cannot share screens. I wonder if this "resolves" the issue for other people. (You may still need to have the Security and Privacy setting added.)

I thought this was only a problem with screen sharing on MS Teams. Turns out that it is much more extensive, as the comments here indicate. Clearly, something in the application permissions changed with Catalina and this Security & Privacy setting is not sufficient to resolve the issue. I haven't found the application that is blocking it for me.

Thanks this works very well for me. I had to try to share my screen in the applications 1st for them to appear in the screen recording tab, and i have to do it every time i need to share. open the window, uncheck the app , quit it, check it again then open again and it will now share for only 1 time.

We are seeing the same behaviour. Any time screen sharing in Skype for Business is attempted this error is returned:

"! Change your settings to allow desktop sharing. Go to the Privacy pane of Security & Privacy and enable Screen Recording for Skype for Business.'

However, in macOS 10.14 Mojave there is no "Screen Recording" in the Privacy pane in Security & Privacy preferences. It may be a key in a .plist .xml file. MS SfB should know this and behave accordingly.

Hey, see my response above.

Try to close Adobe Creative Cloud if you have it running. If not, try to close other applications and see if it works.

You need to upgrade to GoToMeeting version 10.2 or later. It has been updated for Catalina.

This option worked for me. Once I closed all the apps (except Safari) I was able to share just fine with Teams.

I am able to solve it by closing a specific app - Harvest in my case - which looks very random to me but apparently this third party app is interacting strangely with Google Hangouts plugins...

Installing / updating XCode fixed a lot of problems, like Screensharing and Airpods usage. This is probably the reason why Apple devs didn't find it, they have the latest XCode version installed :).

So, it looks like you just have to close apps and open them till you find which one is causing the issue. For me it was Microsoft's "to do" app. Weird stuff. I do wonder who the culprit here is, Microsoft or Apple. It is odd that having another app open would cause the issue. I think that Apple is really dropping the ball on this release. This is something that pretty much all business users will need on the daily.

Im disappointed there has been no urgency to address from either side here since I am a "MS Teams" user, but since this is a MAC issue I feel Apple needs to push out a fix ASAP.

Two suggestions, Danny. Read through this thread, as painful as that is, and try the potential solutions. It appears that this issue has several causes, but it might be as easy as turning off full-screen. If all else fails, I'd suggest finding one of the virtual-machine products like Fusion from VMWare and installing Windows under it. Admittedly this is a huge pain, but I think it is a smaller pain than trying to downgrade your Mac operating system. I run Windows 10 using Fusion and the Teams screen sharing there was not affected by this issue.

And the other side effect is that surely as soon as you invest all that time, Apple or Microsoft will release a bit of maintenance that fixes the problem. So your efforts will help all of us . . .
