If all you are wanting to do is to create a Local site and interact with it, you don’t need any of the other database tools. Those are mostly just to help you if you are wanting to do more advanced work with the Local site’s database.
From the screenshots it looks like you are getting closer to having the site be created successfully!
One thing that might be going on is that the site wasn’t able to be created on the old version of MacOS, so retrying that process on the new version of the OS might be helpful.
To do this, try deleting that site by right-clicking on it and selecting “Delete” and then create a new, site within Local.
Hopefully that gets you a site that you can access within a browser, but if you do run into issues, can you please provide your Local Log? See this Community Forum post for instructions on how to do so:
