macOS now peers over BLE with Linux, Android and other Macs when the daemon runs in a login session with Bluetooth permission. CoreBluetooth is delegate-driven and moves channel bytes through Foundation streams, the same command-out, callback-in shape as the Android embedder's radio, so the backend plays the embedder's part in process rather than implementing BleIo: MacRadio drives CoreBluetooth from a private serial dispatch queue (no main run loop), installs a fresh bridge into its slot each time Bluetooth comes up, and pumps each CBL2CAPChannel with blocking stream I/O on two threads. io_radio gains what that needs: a blocking delivery for a reader on its own thread, since a dropped chunk of a byte stream breaks its framing, and a RadioIo that keeps its radio alive across Bluetooth toggles. macOS assigns the listener PSM and cannot advertise it, so a Mac serves it over GATT (Apple's L2CAP PSM characteristic, specified in psm.rs) and reads a peer's there when its advert carried none. Linux and Android cannot dial a Mac; the Mac's own dial forms the link, which the link arbitration admits. CoreBluetooth hides link addresses, so a peer's identifier is hashed into a stable locally administered BleAddr, and a configured hci0/AA:... peer cannot be dialled from a Mac. The fips binary embeds an Info.plist with a Bluetooth usage description, without which CoreBluetooth kills the process. The Mac has one radio, so more than one ble instance is a config error there. Platform-neutral parts (dial PSM decision, address mapping, advert throttle, stream pumps) are tested on every host; two ignored tests exercise real hardware.
