I’ve been running Kicad on a mac (Osx 10.13) successfully for a while. Since I have upgrade to 5.0 release I seem to have completely lost the “global” footprint libraries. They show as ghosts in footprint association and in pcb place but do not let me open or select them. The .pretty files appear to exist and be in the right location.
The only footprints I can see and use are the ones that I created myself in Kicad 4 and are in a local directory.
Where does OSX pick up the user config info? I think it is getting stale, Kicad 4, settings.
(IMHO, this is a non-obviously location. I never did find it in the documentation or forums. It is obscure, rarely used, and does not show under default search options).
