Mysql can't connect on MacBook

@Eternus
You have to start by setting environment variable in a shell/terminal and then invoking your application from there, to get diagnostic information. I don't know how exactly you do that on Mac, but from Linux:export QT_DEBUG_PLUGINS=1 path-to-your-executable-to-run-itLook through the end of the output for what the issue is.

What exactly are you writing in your terminal ?

You do realize that this is a placeholder text that you have to replace with the actual path to the executable you are trying to run ?
On the other side, you can also define QT_DEBUG_PLUGINS environment variable in the Run part of the Project panel and start your application as usual.

I never said it would be the solution, the goal is to gather information about why the plugin is not loading in order to fix it. And be careful, the name of the variable is all in upper case.

The application output shows one thing: you are misusing the QSqlDatabase class. It also does not show the plugin loading debug data.
Did you add the QT_DEBUG_PLUGINS variable in Qt Creator like I suggested ? If so, did you set it to 1 ?
