1. I am on a 2019 iMac Intel i7 running OSX Ventura. A few days ago a notification popped up in the top right of my screen that a Google system extension had been installed. It said I could modify the settings in "Logic & Control"
WHERE is Logic & Control?
Never heard of it.
2. How the heck does Google (who I HATE!) just install something on my system?
You must have given them authorization to do so. Any time you enter your password to install software, you give that developer full control over your computer and all of your data. Depending on various factors, that control can extend to all of your devices and all of your data in the cloud.
3. How do I get rid of their crap? I don't care what magnificent new functions it adds. I have had SERIOUS issues with Chrome and other Google based applications.
You should probably investigate more thoroughly. I'm not aware of Google using any system extensions, but then I don't use Google software, at least not locally.
If Google is using a system extension, you have to be very, very careful. If you try to uninstall the software incorrectly, it will bake that system extension into the operating system and you'll never be able to remove it or control it.
Furthermore, 3rd party developers have repeatedly proven themselves to be unwilling or unable to properly uninstall system extensions. If you do have a true system extension, the only way to remove it is to drag the containing application to the trash. You will get a confirmation dialog that you are uninstalling the system extension.
There is a slight possibility that they could have their own uninstaller that work. Technically it is possible. But in practice, uninstallers rarely remove system extensions. Any other uninstallation method, command-line, "app zapper", "clean up" tools will fail and leave the system compromised. You must locate the containing app and drag it to the trash. Note that the containing app may be located in a hidden directory. And said hidden directory will not show up in a file search.
4. WHY did the OS just go ahead and install something WITHOUT authorization?
It didn't. Your 3rd party software did.
