Cool, what's your Feedback ID? I can try updating next time from my Mac mini in Bootcamp on Windows. That'd only be Windows 10, though. Keep in mind that you're dealing with a pretty niche situation here (ie: you updating with a cable on a Windows machine), so even my experience may still be different than yours. We're also not using the same cableSecond, the louder I am about this issue, the more attention is brought to it, and the more likely Apple is to actually do something about it and make the maintenance of their Windows software a priority. I would rather complain about it and see some positive change rather than continually handwave it and sweep the issue under the rug. If you’re all tired of hearing about it, you should be louder about it too!
I have provided feedback to Apple, many times, but this is a drum that needs to be beat on a bit more publicly. One person constantly bringing attention to a nonfunctional piece of software from the 3 trillion dollar tech company can only have so much of an influence.
Also, to your point about "being louder"... This is MacRumors, not the official Apple Forum. I assume you're posting there, too? First even? Apple employees will NEVER post something here stating they're an employee. That breaks Apple's own rules. So, sure.. yell about it super loud! But maybe just yell in the right direction?
