I’m following the SQL course of Mosh. After the installation of my workbench, Mosh deleted the connection to build a new connection. I followd the instruction whats easy. However when i test the conncetion i’ll get a warning.

**Connection Warning**  
Incompatible/nonstandard server version or connection protocol detected (9.0.1).

A connection to this database can be established but some MySQL Workbench features may not work properly since the database is not fully compatible with the supported versions of MySQL.

MySQL Workbench is developed and tested for MySQL Server versions 5.6, 5.7 and 8.0

Please note: there may be some incompatibilities with version 8.4.

I have Macbook air m3 and installed the **macOS 14 (ARM, 64-bit), DMG Archive**.

Why do i get this warning and what can i do? Who can help me?

Hi,  
It seems the version of MySQL Workbench (MWB) you are using is older than the version of MySQL. As most feature are rather stable, you will be able to use most of them. But newer versions could come with new features not supported by older versions of MWB.

You can still use it and it will likely work for the most part.

Cheers.
