yet, interestingly enough, Apple are never looking for manual QA testers, just Senior Automation Engineers. Or so it seems to me, a lone brute force manual QA tester who every once in a while wonders what kind of an effect he'd have at Apple.
Have you reported this to http://bugreport.apple.com/ ? I know most of my Yosemite / Mavericks bugs were tagged as duplicates, but there might be some sort of a "wow, so many duplicates, let's fix this" type of ranking re: bugs reported to the Radar.
I, for one, would wish Mr. Federighi would push out a Snow Yosemite. No new features, simply bugfixing. I have taken to simply posting screenshots on my blog about various AppleQA issues. I wish there was a way to really make a difference, god know I'm fanatical enough about wanting Apple stuff to just work.
