I don't know if the iMac has the same ambient light auto adjust as the MBPs do but if it does then that's likely the causes of your problem. To fix it go into system preferences and in the display icon uncheck the automatically adjust brightness as ambient light changes.

Hey, now you’re sounding like a troll, IMO.

Try a permissions repair.

Take a look at the attached image, turn off this feature in your Settings to disable your MacBook from taking control of the light! Just don't go into the darkness.
