f3 and f4 media keys stopped working after 10.13.3 High Sierra upgrade, help!
MacBook Pro with Retina display, macOS High Sierra (10.13.3)
....I did above and still out. The other media keys work well. Do I need to restart maybe?
There's a couple of things:
F3 and F4 on my mac are for the Dashboard and Mission Control.
What are these keys supposed to be doing?
On my mac the media keys (play, volume up/down, mute) are further to the right (F6,7,8,9 perhaps-not at my mac at the moment).
If you are indeed talking about media keys they changed a bit in High Sierra. They control not just iTunes but also QT Player and Safari.
On the rare occasions where they did not appear to work I found that they can be activated by first starting playback with a button or the space bar.
...as i work with multiple windows open at a time (3-6 etc) and when I am not connected to my 30" screen, f3 and f4 gave me the ability to 'spread out' all windows open so I can find what I need timely. (i.e. a window behind a window etc).
You could also try resetting SMC
You could try rebooting in safe mode to see if the problem exists there. Then try a normal boot.
