The 1.1 update is now allowing Rosetta apps to work in Snow Leopard. Huzzah! I'm back to work, and things seem to be running smoothly again.
And the 7.6.1 update for Airport Extreme is now working, too - what, a few months after 7.6 was released?
Yah know, we're not all just reading our email, surfing the web, reading iBooks, and playing games on our Macs. Some of us are actually working in a production environment, on deadlines, to pay bills, and we just don't have time for this. If I let Software Update install an update onto my computer whenever it darn well pleases, I need to know that I know that I know that I KNOW that Apple has properly vetted this software before release, that it's not going to hose my computer without at least a big announcement beforehand, so I can prepare myself and my clients.
These two situations were completely unacceptable, and not up to Apple's usual stratospheric standards.
Now I can get back to loving my Apple products, as usual. All is right with the world again.
