Thanks. problem solved. there was a little app called camtwist causing problems. I deleted the app so I could reset the default camera!
I have a iMac (Retina 5K, 27-inch, Late 2015) running 10.11.6
The built in camera works with photo booth, but is not recognized by CA.
- NO other apps are running or are using camera
- I tried switching cameras via camera menu in app
- I tried selecting Use Default Camera menu in app
Still nothing. I just began to attempt to use this and during the tutorial where it says click on "set rest pose" I did as instructed and nothing ... I would really like to use this app if possible.
