Bluetooth LE advertisements on macOS is not such an open season as it is on, say, Linux.

Apple imposes severe advertising restrictions and has also implemented vendor specific additions (e.g. for iOS clients) in order to work with/around them (!) For example, you can only set the device name and the service UUID's, and even then those items can get replaced when your app is not in the foreground.
