I can't open more than one MySQL connections at the same time in my Mac OS. For example if I connect to a database using Sequel Pro and then I go to Terminal and try to connect to MySQL I get this error:
ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 102
And of course the problem occurs also the other way around even in my websites. If I open MySql using Sequel or Terminal my local websites can't connect to MySQL.
S.O => Mac Os El Capitan MySQL => 5.7.9
