My Docker Oracle12c is running fine. I want to browse it using sql developer from my host machine Mac. I need to tweak some network settings. The Bridge network is fine and I am able to query database CLI sql >.

First you should check the network issues(e.g: firewall is blocking port 1521). If network is ok,

then most probably you have listener configured wrongly, the hostname you specify in connection string must be the same as in the listener.
