This message comes from a Raspberry Pi 4 that uses 3 Amps at 5 Volts (IIRC 15 Watts).
The new Pi 5 requires a 5 Watt supply, because it how has a PCIe connector. OTOH, it has Power over Ethernet in addition to the USB-C power.
The Mac Mini is not world-facing because I foolishly installed Norton Antivirus on it, and that came with a lot of baggage that I don't trust.
Asahi Linux is still on the way.
