MySQL Workbench hangs/frozen on macOS 10.12 while executing a very simple query.
And I have to fore terminate mysql workbench and relaunch it. and it hangs again.

Here is the content in wb.log file:

How to repeat:
macOS 10.12.1, launch mysql workbench
1. open the auto-save connection(because the process was force kill last time)
2. run a simple query
3. hangs, frozen.

What kind of connection are you using (local or remote) and which server version are you connected to. Thanks.

The server locates in the same intranet with the client, and the same subnet.
server: 172.16.1.66
client: 172.16.1.202
no firewall on both the server and the client.

server version: 5.6.33-0ubuntu0.14.04.1-log
