Apple’s new Dashboard Advisory, which attempts to authenticate widgets, seems relatively harmless (meaning it isn’t passing information back to Apple). Unfortunately, that isn’t the point. The issue is whether Apple is pushing the option without notifying the user and/or allowing them to turn it off.
This 10.4.7 user can’t validate any of this, as he hasn’t seen said feature “pop up” yet. But Ethereal may be running for the rest of the day.
