Simon 5 is coming soon!

Simon version 5 is currently in beta testing. It is a massive update, introducing a much-requested feature: syncing the Simon data between multiple Macs, plus a Simon Status service, a Link Checker filter, improved Find filter, iMessage and Speak Error notifiers, a new app icon, and much more.

Important: please note that Simon 5 requires a minimum of macOS 10.12 (Sierra), and will be a paid upgrade from Simon 4 after the beta. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).

Can Simon give a success or failure based on essential text missing?

Yes! The Filters feature includes Find Required and Find Unwanted default filters.

So for example, if you do a telnet Script-based check, you'd want it to be considered a success only if this is output:

Escape character is '^]'

Then if that text isn't found (as would occur if telnet couldn't connect to the server), Simon will log a failure.
