Built in cam / external camera not working after downgrading back to mojave

Hi all,

On my MacBook Pro (15-inch, 2018), neither the built in webcam nor an external webcam work on facetime or any other application trying to use video.


The issue began after downgrading from Catalina to Mojave.


Any suggestions?


Followed some initial troubleshooting but nothing seems to work.

Try applying this standalone Mojave "Combo" updater, which will ensure you're using its latest version: Download macOS Mojave 10.14.6 Combo Update


That's merely a guess.
