Interestedly I tried this again using a test account and launched both Photo Booth and then FaceTime. In both instances the green indicator light was solidly on, however, the picture kept fluctuating between a valid image and then a dark screen with both apps. I then went back to my admin user account and the same occurred.
Looking at the system logs, not sure if these error’s are relevant, so posting here as an FYI (just in case)…
Cleary there is an interrupt occurring for some reason, hence dropping frame and what does this error indicate :-
FlowIC00: MIPI error (interrupt source = 0x2) kernel 0x6c2 ??
Whilst this could still be a hardware issue, the following system logs appear to be of interest. Can I get assistance to decode these and if there are additional events I need to focus on ?
Here is the system log flow....
