@alexr @tdierks @enhancedscurry it could happen…
One of the “features” I worked on way back in macOS Leopard saved Support a lot of time and money. I locked down well known directories with “everyone deny delete” acls. That kept people from easily deleting and renaming those directories which could either break software (for example, iTunes could not find their music) or cause important data to be lost.
A few years later, one of the HI leads wrote several bug reports because he wanted to delete some of those directories using the Finder. He didn’t think he needed them. I had the pleasure of telling him “works as expected” because what he didn’t like was saving Apple money and preventing customer grief.
