It looks like DBeaver does not support connection via a socket, @shelby, which is required for Local on macOS and Linux by default.
You could try connecting via IP as described here: How can I connect to MySQL using TCP/IP rather than a socket on macOS/Linux?
Or you can try another database client that supports socket connections, such as TablePlus or Navicat, or the web client built into Local (click “Open AdminerEvo” at the top of the database tab).
