So, this is a part of the specific reply I got from the company that owns the software I license. I don’t know if it will help, but happy to share non-software specific info:
OK, Sequoia introduced a new security setting.
Please check if [your printer driver] is enabled in System Settings/Privacy & Security/Local Network/ - .
If it is enabled, please install and launch the utility "Discovery" from the App Store, then launch the [printer driver]
I think Discovery will simply tell you if things are connected or running. You may have to scroll down a bit for the relevant info.
What I ended up doing was running the software which in turn instantiated the exception in the network window. Everything was great after that…
(well except for having lost some preferences for a couple of other apps… but that’s another story)
I hope this at least gives you a clue as to where to poke around.
good luck!
You’re correct.
Discovery is a useful app, and one I use around here, though it requires some knowledge of Bonjour.
I am unclear why a third-party app would suggest this path using Discovery (and again, Discovery is a fine app), as the app you are trying to use itself should be able to detect and report Bonjour traffic issues.
As a developer, I’d usually expect to either provide a status or troubleshooting tool within the app, or potentially as a separate tool download, if this case is at all common. (And I’ve yet to encounter a non-trivial local network without Bonjour chattering, so where this is even headed?)
At the command line in Terminal app, the usual Bonjour network troubleshooting tools would be something like ping and dns-sd:
# checks for some chattering for five seconds.
dns-sd -t 5 -B
# checks for basic network connectivity with the computer using the specified IP address
ping -c 4 203.0.113.12
# Replace 203.0.113.12 with the IP address of the other computer involved
But again, just what a person would be looking for with Discovery app (or any of this) is unclear, and I’d guess the app itself uses its own Bonjour traffic, and it would be handy to know what that traffic is, so that the dns-sd command or Discovery could be set to look for it. Without that detail, Discovery is little more than a “is the local network connected and chattering”, and here are other ways to check that.
