Adobe has just released an Adobe AIR update for Mac only that fixes the camera detection issue. Here is what Adobe said:
Today we posted a very minor update for the Adobe AIR 2.5.1 runtime that addresses a known issue related to interacting with a system’s camera on Mac systems. This is a desktop only release for the Mac; Windows and Linux users will not be impacted by this issue and will therefore not be prompted to update.
The build number for the Mac update is AIR 18.104.22.16850. We recommend that users update to the latest version of Adobe AIR.
