Macbook Pro camera stopped working after I downloaded Big Sur.
Help. Even photobooth is off - it's just black in all apps. I tried the System Preference / Security route - NOTHING.
MacBook Pro 13″, macOS 10.13
Try a SMC Reset 3x. and test. No good Reset NVRAM. Still not good. Try this Support Document from Apple. Lastly what is showing in Other Folder >> System Information under Camara - is it losing the built-in camera ? If no, time to consider an Apple Repair appointments
