Out of boredom, I ran the console application that comes with macOS by default. As I was looking through some of the logs, I noticed a line that said:

"msg":"onAvengerAdvertisementDetected: got avenger advertisement", "subHarvester":"Avenger"}

coming from the subsystem com.apple.locationd.Core under the category Harvester. After looking further, I noticed a bunch of other calls using the term "advertisement" in them too. For example, there's:

{"msg":"convertToSPAdvertisement", "address":<private>, "data":<private>, "date":<private>, "rssi":<private>, "status":<private>, "reserved":<private>, "subHarvester":"Avenger"}

coming from the same subsystem and category.

Does anyone have any idea where these logs are coming from?

I'm on a MacBook Air M1 running macOS Monterrey 12.2.1

    Can you add the full line you see in the log, and also name the log file you found them in?

    I'm seeing this as well. Very curious to find out from which app this originates. Did you figure it out?

I can see this same console log message appear whenever I enable (in system preferences) location services for any app that asks for it. The message appeared even after I entirely wiped my computer and reinstalled the OS. By turning off location services for every app (except core system tools), I stopped seeing the message.

This whole investigation began because Google Chrome started constantly freezing on a brand new Macbook Pro.

  • Sounds like another good reason to not use Chrome, rather than going nuclear on locationd. There are thousands of messages a minute in Console that you could potentially get paranoid about without good reason. The vast majority of Console output is for Apple & Third Party devs, not for end users. Commented May 27 at 12:08
