how to add individual keyboard layout under OS X 10.8.5
Using Ukulele I set up an individualised keyboard layout, saved it as a .bundle file and as described elsewhere added it to the Keyboard Layouts folder under Library in order to appear in my Input Sources list (Language & Text Preferences). However it does NOT. However often I add it to the folder and restart my system, no sign of it. Plus, in my system there is no Add button (little plus symbol at the bottom of the input languages' list) as described elsewhere. (see screenshot)
Any thoughts on how I might still be able to add my personal keyboard layout?
