magic keyboard volume function keys mis-assigned
Continuing this thread... magic keyboard numeric volume keys not working
...I am running El Capitan 10.11.6 with a new magic keyboard with numeric keypad. Same symptoms as murf1970 reported. Have zapped the PRAM and reset to default all keyboard settings in System Preferences without success. Found the darkness/brightness controls had migrated to F14 and F15, which I managed to reset back to F1 and F2. But there is no obvious way to reassign F10 to mute, F11 to volume down or F12 to volume up (screengrab 1 below). I can control volume by digging into Sound preferences (screengrab 2) but that's a pain. This is an office iMac I can't upgrade without losing legacy apps.
