Thanks a lot guys! Unfortunately, to help me further, you might need a magic wand - now I need a mac binary with the new features, and also several extensions alongside.
I guess my main worry is that extension builds are completely broken on mac, as I noted in this post, which didn’t get any response: Multiple issues with extension builds.
I guess I should hope that I was wrong and just mis-interpreted the interface of the dashboard, and magically the extensions I need will be accessible tomorrow on mac when I open ExtensionManager…
