I have a brand new Macbook Pro 13.3" Retina and like everyone else have run into the same issues. The 10.8.2 is not appearing in my software update listing. I downloaded the 10.8.2 Combo and it refuses to install. From what I am hearing I am probably better off that 10.8.2 did not load up until after Apple fixes whatever the various issues are with it.
I phoned Apple Support and was advised that they are working on the fix and expect within a few days the update should be available to affect machines such as mine.
This is my first ever Mac. In fact, I only recently moved to an iPhone, iPad, and now a Mac all this year. For 20+ years prior I was a diehard PC and recently Android owner. I'm not letting this update issue affect me since so far aside from that issue I am loving my new Mac. My PC has Windows 8 on it and really I am not impressed. OS X functionality and layout seems so much more intuitive and well thought out as compared to Windows 8. I feel like Windows 8 tried to turn my PC into a giant sized phone or tablet. I get the idea but the execution at this point seems clumbsy at best. OS X seems to me to be way ahead of where Windows is trying to go.
I would suggest to Apple that while it is good they are not letting people load a buggy upgrade, they should allow the Software Update screen to shows 10.8.2 as pending revision and perhaps provide a brief explanation there for users that are looking for it or wanting to upgrade other apps like iPhoto. Lack of communication makes users think that they are asleep at the switch or attempting to hide something. Better they just tell it like it is... I know I would respect that more than having to hunt for answers on what is an otherwise known issue to Apple.
