Running Reunion 11.0.2 on a Macbook that was just upgraded to macOS High Sierra 10.13.2. Just tried taking a picture using the Macbook camera. Video in the camera window is black. After clicking "Take Picture", the image is good, but the composition can't be viewed before taking. Not sure if this has anything to do with the upgrade to High Sierra, since I've never used the camera feature with Reunion before.
Also tried checking "Mirror preview". That gives a live picture that jitters between two frozen frames with no updates as camera or subject is moved. Camera video is clear using Facetime.
