I just unpacked my iMac after sitting in a box for 6 months and added a new Apple bluetooth keyboard. In the "international" settings I set the input menu to that of my country and all keys work perfectly, except for the Function keys.
In Keyboard > Keyboard shortcuts I see that F12 is mapped to Dashboard, while I actually want to use F10, 11 and 12 to control the volume (volume icons are on these keys). If I uncheck those mappings, volume control does not work. Same for adjusting brightness with the F1 and F2 keys.
How can I enable these functions?
