First off, let me say I love my 2015 rMB. The only issue I have with it is that the webcam is almost completely unusable. It's not the 480p that gets me - it's the camera's inability to track motion at all. It seems like the shutter speed gets really slow whenever lighting conditions aren't 100% ideal, with ideal being the bright white light of a 2004 era Apple store. Even the smallest motions of the head when video conferencing (over a local network) will blur the image terribly. Does anyone else have this issue? Any remedies? I really like the machine and it's still under warranty, so if this is an isolated issue I'd like to get it fixed.
