Camera stopped to work on Big Sur's Safari

Hello Marcello_Cruz,

We would like to see how we can help you with using your external camera with your Mac. Do you have any software from Logitech installed on the Mac? If so, are their any updates avaiable? Let's start by restarting the Mac and testing to see if the issue persists. Follow the steps in this link to restart: Shut down or restart your Mac - Apple Support

"Restart your Mac

• On your Mac, choose Apple menu  > Restart.
• If you don’t want app windows that are open to reopen when your Mac restarts, deselect “Reopen windows when logging back in.”

Get back to us with these details so that we have a better understanding of the issue, and we can go from there.

Cheers!

Hi Marcello_Cruz,

As this behavior is impacting only Safari, one possible cause would be an extension or plug-in that is preventing the camera access.

Follow the steps from If Safari on Mac doesn't open a webpage or isn’t working as expected to reload Safari while holding the Shift key, check current extensions, and test in a private window.

Then, if necessary, use the process in How to use safe mode on your Mac to see if this continues in safe mode, and take the recommended actions based on the results of that test.

Regards.

Marcello_Cruz,

Thanks for trying that out.

Be sure to try checking for any updates for the software used, including in System Preferences > Software Update, and within any affected third-party apps that may have their own updaters.

As it didn't happen in the other account, a possible cause of the issue may be login items. This page can help with removing these: Remove login items to resolve startup problems on your Mac

1. On your Mac, choose Apple menu  > System Preferences, then click Users & Groups.

2. Click your account name below Current User, then click Login Items at the top of the window.

Make a list of the login items—you’ll need to remember them later.

3. Select all of the login items, then click the Remove button .

4. Choose Apple menu > Restart.

5. If this solves the problem, open Users & Groups preferences again, add the login items one at a time, and restart your Mac after adding each one.

When the problem occurs again, follow the steps above to remove only the last login item you added.

Cheers.
