Mac High Sierra - Local hangs on "Starting up Site Services"

I know that this isn’t really an answer, but is this still happening with the latest (5.9.0) version of Local?

Since this workaround seems to be working, that makes me think that there’s something preventing Local from cleaning up the MySQL sockets.

Can you please provide your Local Log? See this Community Forum post for instructions on how to do so:

The output from the terminal command you gave ( ps aux | grep mysql ) indicates that a MySQL process was running, but the popup dialog seems to indicate that Local is having issues connecting to the MySQL process.

In that screenshot, I don’t see any site called “Tester” in the sites list. Did you already delete it before creating the AEFAEF site?
