Hey, My Mac book pro's volume, pause and skip buttons and brightness buttons do not appear to be doing anything. I press them and they do not do their intended purpose (they don't do anything). My hypothesis is that I turned them accidentally from volume etc. keys to F5, F6 etc. keys. I do not know how I did this however (did not go into settings). Anyone know what is going on?
MacBook Pro (Retina, 13-inch,Early 2015), macOS Sierra (10.12.5)
Try the following set of instruction
1 Shut Down your macbook
2 Press the power button and immediately press "cmd" + "alt" + "R" + "P" at the same time
3 Keep holding "cmd" + "alt" + "R" + "P" while it powers on and the macbook while make a chime sound
4 Keep holding until the macbook chimes three times
5 On the 3rd chime release the "cmd" + "alt" + "R" + "P"
6 Macbook will start up normally and require your login details
Test the volume buttons to see if they are working
Here's the news on changing those keys to function keys, and more importantly, changing them back: Change the behavior of function keys on your Mac - Apple Support
