Regardless, Intel apps still run in macOS 27. Apple just probably figured that since their newest Airport product is over 8 years old that they could safely end support for it.
I wonder if Apple just hid the app by moving it to an obscure location. I don't have macOS27 at my disposal to test, but if it was just moved, the following command should find it:
So is it no longer possible to manage AirPort equipment at all in macOS, without the Utility app? If so a crying shame, I still use them at home with their own isolated networks for my printer/AirTunes support. For this purpose they work fine...
If so, yet again a great irony as you can still easily manage them from Windows using the Utility app.
