What is happening is that macOS only allows a single instance of an app to run at once. Whilst that is what we want of course, macOS is causing the new instance to exit before it has a change to open a new pgAdmin window. Using "open -n ..." or calling the embedded executable directly resolves that issue. So, there's another challenge to figure out... :-( -- Dave Page Blog: http://pgsnake.blogspot.com Twitter: @pgsnake EnterpriseDB UK: http://www.enterprisedb.com The Enterprise PostgreSQL Company
