Apple under Steve Jobs was not one for hiding cute features into its software.
Known as 'easter eggs', these are small doodads and wotsits that are usually intended to either make a user smile, or else make the developer look cool to his nerdy mates.
But in its latest operating system, OS X Mountain Lion, Apple has returned to its former Easter Egg ways. In a very subtle (and cute) way.
While downloading a new App from the Mac App Store, a specific (and temporary) date is given for when the app was modified in Finder.
And that default date is... 24 January, 1984. AKA the day the first Macintosh computer went on sale.
To see it for yourself, download something in the App store and watch it appear in Finder under 'Applications'.
