iphone as camera, continuity, with Mac Studio

I don't get an error at all and that error seems to be unrelated. It's just that the phone is in the list of cameras when WiFi on the Mac is on, and it's not in the list of Cameras when the Wifi is off. I don't understand why that happens or why it will not use ethernet/wireless network.

The phone, in its capacity as a camera, is connecting to the computer by WiFi unless it is connected to the computer by a cable.

I've never seen a computer behave like a router so this is bizarre. I guess I'll have to remember to toggle on WiFi if I need then.

This has nothing to do with a computer behaving as a router. The phone is connecting to the computer over WiFi to transfer the data stream. A router is not required for an ad hoc connection. My reading of the instructions is that if you connect the iPhone to the computer by a cable, it will transfer the data over the cable.

See this:

If you get a notification that iPhone Wi-Fi disconnected

While using Continuity Camera wirelessly, you might be notified that your iPhone has disconnected from Wi-Fi to optimize Continuity Camera. Your iPhone then uses its cellular data connection for background networking tasks like email and messages. To stop or prevent this rare occurrence while using Continuity Camera, plug your iPhone into your Mac or turn off cellular data on your iPhone.

Huh. Well now I know why Airdrop also didn't work before. Did not realize Apple uses WiFi for non-networked connections. Sort of silly they even installed ethernet, maybe it's for a printer and not a wired network.

I believe the computer is still connecting to the internet over ethernet, but as I haven't used ethernet on my Mac in more than a decade, I could be wrong.

Do you still get the error if you do as the article suggested and turn off cellular on your iPhone?
