OBS virtual camera installed, now can't get rid of it

Could you check if there's a file for the OBS Virtual Camera device in /Library/CoreMediaIO/Plug-Ins/DAL/? If so, try moving it to another location and restarting Mathematica.

Thank you.

Followup question.

How does Mathematica get it's hardware information? And where does it store that information?

I had expected, once I killed the virtual camera (I think I have) I would have expected Mathematica to "forget" that camera had ever existed.

It didn't.

I am not really sure how Mathematica gets this info. I would assume it reads the info from your operating system somehow.

Maybe you could check in other apps (like your browser, or camera app) to see if the virtual obs cam is still listed as a device? And maybe try rebooting?

You should be able to do something like the following: mathematica CurrentImage[ ImagingDevice->$ImagingDevices[[2]] ]

This is according to the CurrentImage documentation
