Yesterday I upgraded my late 2012 21.5" iMac by installing new RAM and a SATA SSD. In order to make the installion procedure easier for me I disconnected the Facetime cable from the logic board. Then I reconnected all the cables and made a clean fresh install of Mac OS Sierra. I noticed that the camera wasn't working in Facetime and Photoboot. After running the "sudo killall NDSAgent" command the camera started working but in System Profile, it says that the camera is UVC. I'm not sure if this is correct or shows a symptome of a problem because the brand of the internal camera in my Macbook is "AppleCamera". Should I worry for this? If so, how can I fix it?
