Went back to my interrupted yawn.

So I'm downloading this bloated update just for new wall papers? :eek:
Yes, that's right. Apple have been spending all its time perfecting its background image catalogue.

What a great name for an OS
What about calling an OS 'Kit Kat'?

You want an OS named for a maximum security federal prison? :confused:

That's the joke...

I think Apple uses automatic tests, which are able to detect certain errors.

And completely unable to detect others, as witnessed by the various "WiFi doesn't work on the new Apple xxx" and "Apple testing patch for yyyy problem on new Apple zzzz" threads.

And, wouldn't you think, that if Apple's automatic testing were so good -- you'd never see a bug in a DP that needed to be fixed for a Release Candidate? Hell, if it's that good then there's no need for DPs and RCs - just ship it raw.... :eek:

Automated testing is an important part of QA - but it's no substitute for letting lots of real users use the software in their real lives.
