I bought the 27" 5k iMac this September with 1TB SD and later upgraded the RAM to 40 GB myself. I have noticed that FaceTime camera is too dark. For example I wear glasses and people looking at me online often ask me if I’m wearing sunglasses! I called tech support and after doing a few tests resetting SMC and NVRAM they asked me to bring it in to the Apple Store (which I will do next Saturday).
To troubleshoot, I also set up another user account and tested the camera through that but with the same results. I also downloaded them program iGlasses through with I can control the brightness, but apparently Mohave didn’t provide enough permissions for this program to work on FaceTime or PhotoBooth.
Has anyone had this problem of a dark iMac camera?
