Thanks for taking the time to address my inveterate curiosity.
I remain inherently distrustful of the UUID test, but I get your "subset" point. (I, too, ran it just to see what it would say.)
And I wonder how many people have gotten caught up in the hysteria despite the fact that they're running Little Snitch, which is why I brought it to the forefront in the first place.
I wonder if Apple's tool will be anything more than another curiosity satisfier by the time it's released?
