I do a lot of work with Beacons and having a great Mac app to find nearby iBeacons is really handy. I wrote an app call Beacon Scan that makes it easy to find nearby iBeacons and Eddystone beacons (the Google take on iBeacons).
It also has a new Dark Mode for Mojave! Some call us crazy, but no, it is just crazy good software.
Also, if you download it and give it a 5 star rating, I will be your friend.
