Apple has told its army of developers that they won't be able to offer cut-down versions or demos on the Mac App Store.
Unlike the existing iOS App Store, which is overrun with 'lite' versions of games and software designed to give punters a taste of the iPhone and iPad goods before coughing up the cash, Apple's on-line shop for grown-up Macs will only entertain full-blown, properly working titles.
In an advisory note on the Cupertino company's Developer web site, Apple warns: "Do not submit demos, trials, or betas for Mac App Store Review."
The note goes on to say: "Your web site is the best place to provide demos, trial versions, or betas of your software for customers to explore. The apps you submit to be reviewed for the Mac App Store should be fully functional, retail versions of your apps."
Apple is obviously keen to keep the noise on the Mac App Store down to a minimum, but as the success of titles like Angry Birds has largely been down to allowing people to play the first few levels of a game for free you have to wonder if developers will take kindly to the company's edict.
