1/2 Star.
As I posted at the Mac App Store: This is NOT worth the download. It’s poorly written. There is no actual support page. The developer’s website isn’t actually up and running.
To give an idea of how badly coded this thing is: After I warily signed up for an ‘account’, I opened the About box for the application to read about the developer. The box says:
Engineering: Some people
Human Interface Design: Some other people
Testing: Hopefully not nobody
Documentation: Whoever
With special thanks to: Mom
I then clicked the Close button on the About box and the entire application CRASHED. This is entirely repeatable.
Summary: Not Ready For Prime Time. No access to the developer or even their name. ‘Version 4.x’? No. This isn’t even v0.01 quality. Maybe it will work in the future? But the implied bad attitude from the developer lead me to delete this buggy thing. (I’m running macOS 10.12.4b4).
REMOVING Ping Console:
1) Trash the app itself.
2) Go to: ~/Library/Containers/ and trash 'net.ratlake.Transponder-Console'.
3) Go to: ~/Library/Application Scripts/ and trash 'net.ratlake.Transponder-Console'.
