> About this Mac

When the user selects 'About this Mac' from the Apple menu, Yosemite phones home and s_vi, a unique analytics identifier, is included in the request. (si_vi is used by Adobe/Omniture's analytics software).

Wow. I am waiting for "Team Apple" to invent a radical defense on this one. But regardless this is shameful on Apple's part.

Does it by any chance depend on checking "Send usage and diagnostics data to Apple" checkbox? Is that identifier used for anything else, i.e. can it be associated with something identifying the user, not just saying that all these requests came from the same machine?

If you read the link it says upfront that this happens after disabling all privacy related options including usage and diagnostics data.

Besides why does Apple need to know the user clicked About This Mac? A crash log I can understand but this is unprecedented level of tracking on a desktop OS.
