What is searchpartyuseragent?

Meanwhile I did (among many steps, mainly deletion of old stuff) two things:

• I ran EtreCheck while searchpartyuseragent was one of the top processes: EtreCheck attributed the process to "Apple"
• I installed macOS from scratch. Also there I found searchpartyuseragent.

For me, this process seems to be part of macOS.

@Apple: I would like to have a list or database of processes, which might occur in the Activity Monitor.

Searchpartyuseragent belongs to the updated "Find My" app.

I've got this process running on two of my Macs running Catalina (a 2018 Mac Mini and a 2018 MacBook Pro). The one I was concerned by was my Mac Mini as it suddenly prompted me for my password with no info, which looks suspicious. I've scanned the machine with Malwarebytes and Sophos AV (which is always running in active protection mode) and they've both come back clean. I suspect this is a new process in Catalina that the techs haven't come across yet, but I don't know for certain. I killed it on my Mac Mini and it doesn't appear to have had a negative impact nor has it returned.

Interestingly, when it asked for a password I'd only just got my Mac Mini back from Apple after having its power supply replaced.

It would be good to have some clarity on what this process does and whether it's actually malware/adware or not.

It's ADware infestation.

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

There is also free Malwarebytes which may take care of it...

Okay, I understood the Adware infestation. However, neither EtreCheck nor Malwarebytes did find the infestation.

Any other tips for tools to find a suitable tool for identification and removal?

If nothings works, I think of a clean installation of the macOS.

I can't tell, it's not part of 10.13.6 or earlier, I do not have 10.14 or 10.15

Any Sys Prefs>Extensions?

PS. Apple won't hear you here, if indeed they can ever hear anybody anywhere.

I don't know. I just got done doing some troubleshooting with Apple Support and two different techs told me it was not a Mac process. 🤷‍♂️ This process is using up to 60% of my CPU though and that seems like a lot.

No, it belongs to the updated "Find My" app in Catalina.

We may pick something out of the etrecheck report that you don't see, but check Sys Prefs>Extensions for one.

Thanks for the info.

Yup, definitely related to Find My app
