Heck, even on Macos 26, I have all the Siri and intelligence toggles turned off. Yet all these processes sitting around.

I foolishly bought a Macbook Air with only 256GB of drive space. Now whenever I need to "upgrade" OS versions, there's not enough drive space to do so. It sure would be nice to delete all this unnecessary Siri bullshit bloat so that I can use my laptop with the latest updates.
