I have macOS setup with several user accounts for different purposes, and in all but one of them the media keys (play/pause, previous, next, and volume up and down) are all working correctly.
However, in one specific account the keys have mysteriously stopped doing anything and I can't for the life of me figure out why. There is no obvious cause.
I'm using an Apple Magic Keyboard With Numeric Pad, with a 2018 Mac Mini running macOS 10.15.3, but the issue began under 10.15.2 (I had hoped the update/restart would fix it).
Other things I've already tried:
- I've checked the behaviour under System Preferences -> Keyboard (it doesn't seem to be a function key issue, as the media keys don't work either pressing the Fn key or not).
- Reset NVRAM
- Reset SMC
The fact that this is only affecting one specific account is the part that has me confused; of all my accounts it's the one I would least expect to have a problem, but the one in which it is most annoying, as it's the one I use for watching TV shows/movies (i.e- minimal running programs, no distractions etc.).
Also it's strange that the issue is affecting both the media keys and volume keys; I've noticed all kinds of annoyances with macOS' bonkers media key behaviour with apps fighting for focus so in any given moment I have no idea what play/pause will actually do, but I've never had any issue with the volume control keys, which also do not work for this user account.
Ive also checked my keyboard shortcuts; but I only have shortcuts for other keys (F5 and F6, and F13, F14 and F15, i.e- all the "blank" function keys on my keyboard that do not have special behaviours).
Now, if there's no other way to resolve this issue, I'll of course have to remove and recreate the user account; not the end of the world, but I'd very much like to avoid having to do this if I can.
Does anyone know of any likely reasons why a single user account would have non-functioning media and volume keys, when all others are functioning normally, and how I would go about fixing it?
