Can't change keyboard shortcuts
I'm logged in as the Administrator. I go to System Preferences/Keyboard and to the Keyboard Shortcuts tab. I select Launchpad & Dock from the left column and check Show Launchpad on the right. A field appears to key in a command but nothing will type into that field. When I checked the other items that are in the left column, none of them will allow me to type anything into the field either.
Not sure what I could be doing wrong but if you have any ideas let me know! Thanks for the help!
