CAReportingservice

Just some food for thought:

First, there is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac.  This documents describe what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community and Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support.  

There are no known viruses, i.e. self propagating, for Macs.  There are, however, adware and malware which require the user to install although unwittingly most of the time thru sneaky links, etc.   

Anti Virus developers try to group all types as viruses into their ad campaigns of fear.  They do a poor job of the detecting and isolating the adware and malware.  Since there are no viruses these apps use up a lot of system resources searching for what is non-existent and adversely affect system and app performance.

There is one app, Malwarebytes, which was developed by a long time contributor to these forums and a highly respected member of the computer security community, that is designed solely to seek out adware and known malware and remove it.  The free version is more than adequate for most users.  

Just follow the recommendations in the two articles I linked to and you'll be safe.

Excellent Work and thank you for this posting.

Certain aspect, the honest are above my knowledge base.

Just hope the Much More Technically Inclined Contributor @ James Brickley rejoins this question with detailed insights.

Best I can offer in the interim are a few suggestion below

1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading 

3 - Does the issue present in this mode ?

4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.

5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.

7 - Download the Application Etrecheck directly from the Developer.

This is a Diagnostic Tool that makes no changes to the computer.

It makes a coherent and readable inventory of both the Hardware and Software used on the computer 

The application is free or paid from added features. 

The Report will Not Reveal Any Personal Information. 

Post back the Full Report - copy and paste - >>>> using the Additional Text Icon ( 3rd Icon to last ) <<<<

We can have a look at the report for possible issues and may have possible suggestions to resolve the issues.

Am not sure of some of the details in your above reply.

If possible, in the Activity Monitor instruction earlier, if you could do a Screen Shot ( 3 keyboard combo Shift Command 5 ) and this should make an Image file.

Then post back using the the Second to Last icon.

The this would give us a more clear understanding of what you are seeing

refer to below on where the Image Insertion icon is located

Yup appearing in this machine running Ventura 13.1 on M-Class Computer

From what I can make out is it is a Native Apple Process and is connected to the Kernel Process as the Parent process.

What it actually does is beyond my pay grade to explain.

An confident, there are far more knowledgeable Contributors that may pick up this question and perhaps shed more for details on this process

Seems to be or Is are not the same

Aside from the fans like jet engine which could be many Others processes causing this issue

Suggest opening Activity Monitor >> View >> View ALL processes and identify the process using the most CPU and or Memory

Hey P. Phillips, I used top to figure out it was this using over 95% CPU. there was nothing else of noteworthy CPU consumption. I would not be here otherwise. I should have looked at load while i was at it but i didnt.

HOLY CRAP!!!1 I might as well stay on my windows machine if this is where we have gone with Macs.

i will dig around some more and see what i can find

been using macs since the late 80s with a bit of a hiatus.

2004 since Motorola PPC with OS X 10.4 Tiger

From my observations and in a very general way, most issues, not all, are rather self inflicted issues.

Where it be unintentional or by the installation of some type of Software that will Modify an otherwise working machine and OS

The above is not intended to the owner but as general Observation

Possible Trouble Shots method has been provided.

I understand and thank you for the tips in troubleshooting this. I will work on it in the next few days, time permitting. I have 2 macs, one 2019 MBP intel (primary, personal) and one 2021 MBP M1 (secondary, work). I have my personal icloud account set up on both. there is lots of handoff attempt of my airpods between the 2 macs and my phone. i noticed that on the work mac CAReportingService was taking up a whole core worth of CPU. i put the airpods away and work computer's CAReportingService process calmed down how ever the personal machine has not.

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.

You've got something somewhere using Core Audio / AudioToolbox otherwise that service would be mostly idle. It's not the service, something is making API calls to Core Audio / AudioToolbox and that service is a symptom of the problem.

Use EtreCheck to look for background things running, etc. Check all audio software, anything that uses audio.

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.

Or just reboot the Mac more frequently. There's still a lot of bugs in Ventura 13.1. This is why most businesses will avoid upgrading to Ventura for another few months to a year in most cases. They want those first few dot releases to squash most of the bugs.

This morning my supposedly sleeping intel 16" MacBook Pro 2019 was warm, found CAReportingservice at 100%.

Have rebooted and behaving itself now.

I don't know if it's related to CAReportingservice crashing, but my old Apple 102 key keyboard connected via CalDigit hub is spitting out 's. Scared the crap out of me when I couldn't login.

option-cmd-esc and force quit finder (button will change to "relaunch"). that fixed my careportingservice issue where it was using 100%cpu. might need to kill careportingservice process using activitymonitor as well. unfortunately this is not a final solution as the issue may resurface the next time you use finder.
