Just upgraded my machine to OSX 10.9 Mavericks.
As part of the process, Mail needed to upgrade itself “… This may take a few minutes.”
So underneath the steadily progressing status bar I spied some text that said: “While you wait, you can read about the new features in Mail. Read more….”
Only problem was that clicking on the “Read more…” link took me to a little screen that said:
“The selected topic is currently unavailable.
The topic you were trying to view could not be found.”
Quite and an unusual Fail for Apple – they are usually really good at sweating the small stuff.
