Why can't I share my camera on macOS Catalina?

Hi,

We have had a support ticket open with Apple for this issue, but they are requesting more information from systems that are experiencing this issue. If the work around of opening the GoToMeeting Preferences from your Toolbar and selecting Webcam does not cause the security prompt, please do the following on your Mac:

1. Launch Terminal (/Applications/Utilities/Terminal.app).
2. Enter this command, followed by the return key, at the Terminal command prompt: sudo sysdiagnose
3. Enter your administrator password when prompted (for sudo access).
4. Press return again (or enter) to proceed with the sysdiagnose capture.

Note: The sysdiagnose process can take 10 minutes to complete. Once finished, the folder “/private/var/tmp/“ should appear automatically in the Finder and the sysdiagnose file there will look similar to this:
“sysdiagnose_2017.08.17_07-30-12-0700_10169.tar.gz”

Note: The sysdiagnose process can take 10 minutes to complete. Once finished, the folder “/private/var/tmp/“ should appear automatically in the Finder and the sysdiagnose file there will look similar to this:
“sysdiagnose_2017.08.17_07-30-12-0700_10169.tar.gz”

Go to https://feedbackassistant.apple.com/welcome to provide Apple feedback about the issue and attach the sysdiagnose file before submitting it. Apple will give you a Feedback ID, if you report that number back to us we will be able to reference it with them as we follow up on our ticket.
