MySQL Workbench 6.3 (Mac Sierra) hangs on simple queries.

When I enter a simple query such as

            select * from `devices`;

        

and click the lightning-bolt-with-cursor icon, the query starts, indicated by the spinner activating next to the "SQL File 4" tab in the following screenshot. However, the query doesn't complete and it just hangs. The white-hand-in-red-stop-sign icon is disabled.

I can only force quit MySQL Workbench from this point on. If I try to do a regular quit, nothing happens.

How can I consistently run a simple query on my database? Sometimes it works (maybe 10% of the time), but it mostly just hangs.

Resolution:

This seems to be a bug in MYSQL Workbench 6.3 on Mac Sierra

I found that if you use the latest 6.3 version, that in order to get queries to work, you have open a first connection and ignore it and then open a second connection. This creates two tabs in the workbench. If you perform your queries in the second tab, it works. If you try in the first tab, it hangs.

I also have found that you have to do a force quit the workbench.
