Earlier quoted context omitted.
I'm fairly sure the article is wrong. For example, someone found strings in Google's implementation that mentioned AWDL: https://social.treehouse.systems/@nicolas17/1155847323390351... Also people have mentioned having success Airdropping to macOS devices, which are not listed as being supported on the Wi-Fi Aware page.
> macOS devices, which are not listed as being supported on the Wi-Fi Aware page. Not listed, but shipped with some Wifi Aware library /System/Library/PrivateFrameworks/DeviceToDeviceManager.framework/Plugins/WiFiAwareD2DPlugin.bundle
Another fun thing to do: `ping6 ff02::1%awdl0`. Pings all nearby Apple devices with AWDL active. Including things like your neighbor's phone that's not even on your local network. (but addresses rotate I believe so can't track persistently)
