Again, it is an Apple System service relating to Core Audio and Audio Toolbox. Here's the immutable path on the System volume:


/System/Library/Frameworks/AudioToolbox.framework/XPCServices/CAReportingService.xpc


On my systems it's sitting at zero CPU most of the time and has been active since the last reboot. In my case it has 2 threads. It's using 48.2MB's of RAM zero bytes of disk or network activity.


When playing music in Apple Music or Plexamp, I can see some small CPU spikes. So are you doing stuff with audio? Streaming? Playing audio? Running audio software? Converting audio, Recording audio? Have audio software that might be causing this Apple System service go crazy?


Using any audio hardware? I have a Focusrite Scarlett 2i2 over USB-2 that powers KRK studio reference speakers w/sub-woofer and handles dual instrument inputs / microphones.

James, Thanks for the tip on etrecheck I will check it out as time permits. the only thing audio wise I can think of here my airpods getting tossed around between the 2 macs and my iphone that are all on my desk. This is something that they do on their own as they are all logged into the same icloud account.


Before I saw this I used a gentle but firm application of kill -9 ` ps aux | grep CARerporting | awk '{print $2}' ` last night and things seem to be ok. As of this morning the process has respawned on its own but is at a much more normal CPU consumption level. if it goes sideways again I will make it a priority to get etracheck figured out and see what can learn.

No, I don't think it's deliberate - more the fact that apple have 10 not-amazing engineers doing what 1 insanely good engineer used to do, so they have more, but worse features and overall stability. MacOS has gradually become extremely bloated in the past 10 years, and with more bloat, comes more potential for poorly engineered code. I remember when they launched the stupid (sorry but it was) task bar and, when opening a quicktime movie (which by the way if you're a creative you're doing all the time), CPU would go to 100% for about the 1/2 duration of the movie clip to generate the stupid useless thumbnails that appeared in that task bar, because they'd use software decoding for that useless feature. This would tank my battery when trying to preview clips on the plane, for example. I tried to escalate through support but of course got nowhere. The bug remained for years. In the mean time I found a tool that forcibly turned off the task bar, which solved it.
