Not able to share screen after catalina update

I ran into the same issue with GotoMeeting on Mac. There is an easy solution. Click the Apple in the upper left hand corner of the screen > System Preferences > Security & Privacy. Click the Privacy tab at the top of the dialog box. Scroll down on the left hand side of the screen to Screen Recording. Check the box next to GotoMeeting. You will be alerted to quit GotoMeeting before the change can take place. Then re-start GotoMeeting. You will be all set to now share your screen.

Have had the same problem with Google Meet which has been asking to be granted permissions. Have my browser Chrome enabled already in System Preferences->Security & Privacy->Privacy->Screen Recording. But it still doesn't work.

SOLUTION:

I was quite surprised to hear from others in this thread that other running apps might be the problem. So I started quitting them one by one, and checking in between if screen sharing (in Google meet) would work.

Closed Excel. Nope.

Closed Powerpoint. Nope.

Closed Photos - TADA!

For me, it seems the Photos app (yes, by Apple) was creating the problem. Far fetched, but yes...

Note: MacOs Catalina 10.15 on a Macbook Pro, Latest version of Chrome

Full Disk Access is a new security feature in macOS Mojave that requires some applications to be given full permission to access a user's protected files. In previous versions of macOS, this permission was automatically given to all applications at the time of installation. If a user chooses not to give Full Disk Access, some data on the Mac will not be accessible.

You may as well check it under this settings to allow it manually below:

System Preferences -> Security & Privacy -> Privacy Tab and then check the list of apps that you want to allow.

Hope this able to help you out regardin on this concern.

I found that closing Photos solved the problem for me. I tried re-opening Photos, got the same error message, closed Photos again, and screen-sharing worked again.

Disabling/Enabling Screen Sharing on System Preferences did the trick somehow. It is now working fine.

This is what worked for me. It seems the issue is the way Catalina deals with System Preference > Privacy > Screen Recording.

1. Open this dialog (it will probably be blank)
2. Open your app and start a session then attempt to screen share
3. The app should give you a notice that it needs permissions
4. The app should show up in the dialog list
5. Check the box
6. You will need to restart said app (so do this before a real meeting)

Was able to add; Teams, Skype and Zoom this way.

Screen sharing issue with Bluejeans after Catalina update

• Make sure you are using Bluejeans 2.x version. If not, you can download it from https://www.bluejeans.com/downloads
• After installation go to System perferences > Security & Privacy > Screen Recording and check/allow Bluejeans
• Then go to System perferences > Security & Privacy > Accessibility and check/allow Bluejeans
• Restart your machine (this is how it finally worked in my machine)

I had similar issues with webex and it not showing up in the screen recording list. Although not quite intuitive, for me the fix was to open quicktime and select new recording (as I was trying to record something on my iPhone), at which time I got the prompt for Quicktime to be added to screen record permissions and subsequently I got the prompt for Webex as well, where previously webex was not in the list.

This worked, though there are no explanations or instructions. From another users:

Possible Solution:

If you have a Logitech Unifying receiver or use the Logitech Control Center. Read below.

The latest update of Catalina (10.15.1) did not help. However I did notice that my keyboard was having problems, and it has a special driver. If you are using the Logitech Unifying receiver, and have the Logitech control center installed, update to the latest version. It captures all the keystrokes to work.

Updating The Logitech Control Center to version 3.9.10 allowed me to screen share again.

Updating the Logitech

Figured out a workaround. Put Skype and/or Teams into full-screen mode and share the screen. Once sharing initiates, you can go back to a window and share to your heart's content. Not sure what is going on but the sharing permissions are definitely messed up if you try to share the screen while in a SFB or Teams window. All permissions are set per the earlier posts in this thread.

+1 to kai_andrews's suggestion of putting Skype for Business in Fullscreen mode and then sharing the screen. I already had Skype allowed under Privacy and Security->Screen Recording. If I don't have it in Fullscreen mode it errors, but it works to start the screen share in Fullscreen Mode and then restore it to a regular window.

This is what worked for me too, but instead of a picture app it was an app I use all the time called Dash.

Once I turned that off I was able to present through Google Meet.

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

Since the Security and Privacy option didn't work for me, I systemically went through my applications to determine if one was causing the problem. I discovered that a widget called "Harvest" (time-logging application) was my culprit. Once I quit Harvest, I could screen share once again.
