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

I couldn't agree more, We have an annual contract and when that's due for renewal next year, I'm really thinking of moving everything over to Zoom.

It looks as though there's absolutely no development going on with GotoWebinar, whether it's this issue or trying to get people's audio connected, the lack of virtual backgrounds, you name it it's just getting a bit tired and I'm struggling to find a reason to keep with it.

However, try the gotomeeting fix, it seems to fix things when I've done it, gotomeeting seems to work where gotowebinar doesn't and then fixes the permissions with gotowebinar.

I was having the same issue today with a tech check. Nothing on the macbook would fix it. They even has an external mic and that was picked up but not the internal webcam. Why has this been an ongoing issue for years? "Sometimes it works and sometimes it doesn't make us look silly"

I have had 3 people with this exact issue and I managed to solve it twice doing this:

Finder > Go > Computer
Macintosh HD > user > click on your account > Get Info
Sharing & Permissions: Click on the lower right lock and enter password
Click on the gear mark at the bottom > Apply to enclosed items > Click OK for the pop-up window (Applying permissions...)
Reboot your mac

The third time it didn't work....

Have you seen this discussion?

It is an odd workaround, but apparently works until GoTo can update GoToWebinar.

We are experiencing a lot of problems where GTW/GTM does not even show up in the microphone/ camera/ screen sharing setting. The issue persists even after a restart of the computer. This resolve in that our presenters can not join our meetings.

We have had to move to Zoom for 50% of our sessions.

Is there a solution for this? Is there any specific information available what to do as an presenter when this happens? Do you have any download link to resolve this problem?

Thank you!

Following AmnonR's brilliant solution, I now have a permanent GotoMeeting room and link set up and the moment somebody can't get their permissions to work, I fire them that in an email they open the meeting and they get asked for the permissions, seems to work every time.

Actually had the Mic not getting permissions this week, camera worked fine.....ho hum.

This sounds like an easy suggestion but with many presenters not being tech saavy, this is a huge issue.  They don't know how to log one of these tickets, nor are they that interested in doing so when they are a one time presenter.  This is an issue (one upon many) that needs to be resolved.

We have used GoToWebinar for hundreds of webinars over that past months and given the competition out there it's a bit outrageous and unfortunate that GoToWebinar is so far behind on so many aspects including this one (given it does has a few small advantages).  

The support for this issue has also been underwhelming. We have just posted this video which we believe solves the issue in about 10 seconds: https://youtu.be/s4-w0pGneic 

Hi AshC, thanks for this info!

You may have already posted an update on this in another thread, but do you mind posting something here as well? I'm getting a lot of negative feedback from my mac users and they're starting to just use other software solutions.

Thanks!
