Not able to share screen after catalina update

Facing the same issue after Catalina, however accidentally once i reduced the size of my chrome browser & presented again & it started working. Hope it works for you too.

Yes, same issue. Can't share active application on screen in Gotomeeting, Skype, or Webex. Sales issue with all, can see the screen saver but can't see the active screen (e.g. Finder, Excel, PPT, Outlook, etc.). Was told the apps running aren't latest version supporting 10.15, but in reloading them the sales problem occurs. Only option at this point is to revert back to prior OS version to get it working in the short term.

Same. Skype has updated twice in the past week and today I couldn't share. I was running Mojave, which doesn't have the screen recording option in privacy settings, but I got an alert in skype telling me to go set it... and so against my better judgement I upgraded to Catalina and the screen recording option is there. I enabled it for Skype (for business) and still get the same error message.

This leads me to believe that it's a Skype bug and not a OSX bug, but it could be a combination of both.

This isn't working for me! I've tried at least ten times, even rebooting the computer several times and the absolutely only way I can get it to work temporarily is if I have the security lock unlocked while I do the screensharing. Chrome then has to reboot (while the lock is unlocked) before my screen sharing works. And then it only works that one time.

Rebooting Chrome every time I need to share my screen in a meeting is not tenable. My job requires screen sharing several times a day.

In my case it was Little Snitch's Network monitor app. Thanks for the tip! :-)

I found one solution for Google Hangouts Meet!

Try reducing the web browser screen from Full Screen and now share the screen... hope it works!

You can now go to Full Screen

You are welcome!

Thanks lwucuan - Try reducing the web browser screen from Full Screen and now share the screen... hope it works!

FWIW the 10.15.3 update did not change this issue for me. I can share my desktop using the Microsoft Teams desktop app (no browser involved) only if I am NOT in full-screen mode in the application.

This is not the only thread on this issue. It appears to have several causes. My solution was to not try to share with Teams in full-screen mode. YMMV.

I have tried all of the above tips... nothing has worked except the very strange, close all other open applications tip! Thank you! In my case it was either Microsoft Office suite of apps or Safari. I tried shutting down all adobe products first, that did NOT work. I have even sent logs to Apple Engineers and they just said call Google! The strange part is, if I log in as a test User on my Mac, log into the same google account and try to start a meeting, it asks me if I want to share my screens and then it works! But in my main account on my Mac it does not ask about permissions and even when Permissions are checked, then I unlock and uncheck to restart chrome and reset the permissions, google shuts down chrome, I restart chrome, check the permissions box in system settings, and try to share on a google hang out meeting, it doesn't work. I have been trying this since the day Catalina came out, massive waste of time! Wish they actually knew how to fix this issue.

For me i think the issue here isn't that the privacy isn't aloud (it is).

It's that I use multiple Chrome Profiles, and it's therefore freaking out this new Mac OS permission... I've allowed it for one profile but not for the others maybe?

It looks like I must have accepted permission on for "chrome", but in fact I've not accepted for all the profiles, and therefore non are allow screensharing.

I actually had the issue after a Skype update while using Mojave. In Mojave there was no such privacy setting (for screen recording), so I updated to Catalina and, while the setting was there and I set it for Skype, it didn't solve the problem. Since the bug exists for other non-microsoft screen sharing applications, my guess is that it's a bug that Apple introduced to application developers when they provided info on their new privacy/security settings, and screen sharing applications thus carried this bug over to their applications. Regardless, I think it will require fixes by both Apple and Microsoft (and other screen sharing applications).

I joined the "office insider" program to get early releases of updates and got a skype update today. It still didn't fix this bug.

Catalina Screen sharing does not work for me too, No external application, only the builtin screen sharing of macOS which uses the vnc is giving me a black screen, even though it is connected to the remote and funnily enough moving my cursor on the remote, shows the client cursor is moving too, but on a black screen! None of the solutions on this thread worked for me.

Edit: Using ARDMonitor app on the remote computer I can confirm that the client is indeed has administrator permission to access the remote computer and yet shows black screen.

This is awesome it worked for my Google Hangout but I just clicked the "chrome" icon and everything worked well. THANK YOU!

Having same issue with skype for business, screen recording permission is enabled, but unfortunately since the upgrade to catalina it doesnt work. Ive tried uninstalling, deleting all sfb files, still no luck :-(
