Question: Airport Utility Launches on its Own
I am running 10.13.2, fully patched. Yesterday Airport Utility launched itself. I logged in to my Time Capsule, and then the red badge appeared (no red badge unless logged in; that is new behavior as compared to older versions of OS X). I let the TC update the firmware. This morning AU again launches itself. After logging in I discovered there was no firmware update waiting.
Why would AU launch itself out of the blue?
