Changing keyboard shortcuts presets in El Capitan
I'm using El Capitan.
Before updated to the new version, I usually familiar with 'command+space bar'
to change between two input languages.
But after upgrade it became 'control+space'.
I tried to change the keyboard shortcut preset but by using 'Ctrl+F7' as instructed
the system preference didn't allow me to change anything, even my account priority is admin.
Is there anyone know how to solve this problem?
Thank you
