If the camera works normally each time the Mac is restarted, but disconnecting and reconnecting the camera’s USB cable causes the Mac to stop recognizing it at all, your Mac may be running an old version of Jamf (Casper). Due to a glitch, USB input devices like the camera may disappear in between logins if a login window has been configured through outdated versions of Jamf.

We have been advised that this issue has been corrected in Jamf version 9.98, so updating should resolve the problem permanently. If you’re not running Jamf (or Casper) or need further assistance, please contact us for support.
