Installed logos 6 today and it won;t open. See logs8078.LogosLogs.iCarter.20151223-140735.zip
The log states 'Access to the path "/Users/iCarter/Library/Application Support/Logos4/Users" is denied'. If you know about permissions then you could try to correct that, else wait for a more knowledgeable Mac user or Faithlife.
Dan,
It is now open and downloading library. THANK YOU
