keyboard F11 confused
My setup : iMac (mid 2015)
with Bluetooth keyboard.
BUG : function keys are confused !!
When I press F11 to reduce volume, something else happens : all windows are minimized ?!?!
I tried with another Mac bluetooth keyboard : just the same.
so, it is not the keyboard, but the iMac ... but WHAT ???
