No Camera Available Error on macOS Catalina

Camera hasn’t been working for the past 4-5 weeks. I’ve tried every solution that I found online. Resetting PRAM, terminal commands etc. Nothing worked. This morning I updated to OS Big Sur and voila. Camera is back to life.

Awesome, I can't wait to see if the same is true for me. I'm highly skeptical if it will stick though, since every upgrade in the past has only temporarily restored my built-in camera. See my post earlier in the thread for a detailed explanation of what's happening.

Ohhh man really?? sounds a little ice on my fire... well which device u r using and r u using any adobe application, as i am a graphic designer and i want to knw the compality issues with adobe. every time i am suffring wen ever m updating to new os especially catalina. made my 1 week dead running behind on it... so really need to knw ur experience regarding the Camera and Adobe..

I updated to big slur on my MacBook Pro 2017 with Touch Bar and still the camera is still not fixed. I have done everything including the Karsperky. It still won't display the camera. I refuse to play $900 for a new screen when it broke without a users error. I hope apple starts seeing these common issues and compensates us. Clearly we all have similar issues not caused by us. Anyway hope you get yours fixed.

As I answered previously, "Look at this setting in the Kaspersky Internet Security settings:I had this set to "BLOCK". As soon as I UnBlocked it the camera started working! Finally!!"

I hope this helps.

Is there an Apple representative that can confirm beaulm's response above? If this is the case, customers should have the right to know this. I have spent hours trying to fix this to no avail. I spoke with Apple support back in April and none of their recommendations worked. I too assumed this was a software issue, so I didn't push the issue, assuming an OS update would fix this. You would think Apple would want to fix a camera issue on their laptops, as many users use their cameras all the time. I am now hesitant to even upgrade to Big Sur after having this issue with Catalina and reading about all the other issues users are having with Big Sur (I do not want to get my computer bricked!). Apple, do you see the problem you have left your customer base in? I work in software and am well aware that bugs slip through the cracks, but it would be great if Apple could help out its very loyal customer base. I have talked numerous family members into purchasing Macs. This is just disappointing.

it’s such a wrong thing. There is clearly some issue on Apple’s side so many people’s hardware is malfunctioning because of their upgrade. It’s really annoying that they are not releasing information publicly and admitting that this is an issue generally

I have the same problem, I would like to add more information to this topic. In my case, I updated my computer to Catalina version. After this installation, I realized that my webcam didn't work. I have tried as well with an USB camera (Logitech).

This problem persisted and I can confirm that my webcams are not broken because I can use them with my Bootcamp partition (in the same computer) with Windows 10.

Like you can see I am one more for the list with the same problem, thank you so much to the community for your help.

I just had this error after upgrading to 10.15.7

After some stress, I fixed it by:

1) opening Screen Time in System Preferences, then adding my browsers, FaceTime, Zoom, etc, to the section "Always Allowed"

2) restarting

3) tested things starting with FaceTime (I figure Apple is going to be the most relaxed about their own software).

The camera and microphone worked as normal in all the apps. I also noticed whereas before in Security & Privacy, the Camera and Microphone sections didn't allow me to add anything, those areas were now behaving as one would expect.

Reboot your computer

or

Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

Try resetting the SMC https://support.apple.com/en-us/HT201295

ira199 is right!

Look at this setting in the Kaspersky Internet Security settings;

I had this set to "BLOCK". As soon as I UnBlocked it the camera started working!

Finally!!

Thanks ira199.

I have this issue too and none of these fixed it. Any other suggestions?

I was told the same exact thing AFTER even speaking with an engineering team. Seems like it has to be a software issue considering my camera was working an hour before the update.

I also encounter the same problem and did all the above. Please help.

Same with me, I tried everything at the end I updated Catalina to 10.15.5 but still no success.
