You would think that macos didn't have problems, but I recently cleaned up someone's mac after I noticed a LOT of redirects when loading a website in safari. Lots of weird directories with almost the right name, launch daemons, things that would re-install themselves when removed, etc. the situation was basically nuke from orbit and start over. this was a few os's back on intel. Maybe it's better now?

I can’t remember exactly when macOS made the change. It was a few years back. >The system domain contains the system software installed by Apple. The resources in the system domain are required by the system to run. Users cannot add, remove, or alter items in this domain. https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html https://developer.apple.com/library/archive/documentation/Fi... I’m sure it’s still possible to junk a system up, but a user shouldn’t be able to screw up the actual system files. /Library is probably the biggest wildcard, as it impacts all users on the system, otherwise, creating a new user account should clean up pretty much everything, without having to reinstall the OS itself. I assume making a normal user account for the persons could allow the admin the ability to prevent the user from adding things to /Applications and /Library. The user would still be able to install apps using a ~/Applications folder and have settings in ~/Library. ~/Library is typically used automatically, while ~/Applications is something that needs to be created, but works just fine. I use this at work to install some things I would otherwise not be able to install.

  I don't recall if that was after APFS and the immutable system. I do remember the stuff I tried cleaning up was in the user's home directory. Not exactly this name, but it might be a directory 'ApplicationSupport' instead of 'Application Support' or something like that.

    My guess would be whatever subfolders were in the bad Application Support folder would point to the poorly written software that needs to be removed.

      To be clear, it is not "poorly written" but malicious and hiding itself.

Same thing happened to me with Mac Keeper malware. Some bogus software I downloaded automatically checked a download Mac Keeper checkbox and it was down the rabbit hole for a few days. I think I ended up doing a clean install on a days old back up to rid my self of it. It was years ago on an Intel Mac.
