I have got the same problem using Kodi 16.1 Jarvis on a Mac (OS: Mac OS Sierra 10.12.1)
Despite deleting Kodi by removing the application from the application folder; any re-install bring the same unmet dependancies error.
When I go to /Users/<your_user_name> there is only ‘Applications’ and NOT ‘Library’
When I go above /user/ there is a ‘Library/Application Support’ folder (directly on the HD) but no Kodi within that folder.
Hence, I really don’t know what should be deleted to remove the error, nor where it is located.
I am really puzzled here, Any help welcome
Thanks
