I am working with GMail in the latest El Capitan PB 5 and in Apple Mail my GMail will not get connected. I have two-step verification and I need to put in the app specific password but Mail will not let me . The "Automatically detect and maintain account settings" is grayed out and so I cannot change my password. I cannot get this to uncheck either? Any way to get it the "Automatically detect and maintain account settings" to show back up again so I can change my password? Strange error but I am sure I am not the only one. Thanks.
