The backlights on the keyboard require a system driver to function, and rebooting to Safe Mode will force a cache rebuild that might reload the driver properly. As an extra step, you can try rebooting to Safe Mode and then restarting normally to see if this helps clear the problem. When doing this you should see the backlight turn off and back on, and hopefully resetting it in this manner is all that's needed. If so, then the problem is with the keyboard's backlight itself, but if not then the problem is likely rooted in the system software configuration.Ī simple initial step if the backlight appears stuck or nonfunctional is to restart the system.
If you cannot see a change when performing these actions, then the feedback mechanism for automatically adjusting backlight levels is not working.Īt this point you can try using Photo Booth or another video program to test the camera, or enable automatic display backlight adjustment (in the Displays system preferences) to see if either of those features work.

The Mac uses the the camera's light sensor to determine how to adjust the keyboard and display backlights if you have them set on auto, so shining a bright light into the camera should show a change in the backlight level.
First, if you have the system set to autoilluminate the backlight (which can be done in the "Keyboard" system preferences"), then check whether or not this is working properly by shining a bright light into the system's iSight camera located at the top of the display. When problems with backlights occur, there are several things you can try to address the issue, which may be rooted either in a fault with the hardware or with the operating system.
Have you seen this happen or heard about it? The backlight indicator appears when using the function keys to adjust the keyboard backlight level. I have messed with it all and won't budge to adjust (unless I use the function keys). Now I know there's F5 and F6 to adjust brightness but as well as the "automatically adjust" setting in Settings/Keyboard.

Recently MacFixIt reader David wrote in with such an issue: I picked up a new MacBook Pro 13.3" and noticed this almost immediately at work the next day.the backlit keyboard was on full blast. When you press the F5 or F6 buttons on the keyboard, the system should show a semitransparent backlight level indicator at the bottom of the screen, but if you have auto backlight adjustments enabled, then the system will not show any level indicator and just brighten or dim the backlight as is necessary however, in some instances these options may not work as expected. To adjust the illumination you can either press the function keys on the keyboard (usually the F5 and F6 keys) or enable automatic adjustments however, there may be times when these adjustments do not work properly.
