In addition to continually updating DEVONthink, team Devon also has a nice catalog of free software and utilities for Mac users. Earlier this month, they re-released their Neo Network Utility.
In essence, this application takes a lot of information available on the command line via Terminal and wraps it in a nice user interface. It offers various networking tools for retrieving information and diagnosing network problems. Best of all, it’s free. Note that version 1.0.2. requires macOS Ventura or later.
