Apple has released a software update for its new Magic Mouse, allowing all Mac users running Leopard and Snow Leopard to use the new mouse even though stock of the new product can't be found in retail stores.

Apple has so far only offered the new touch sensitive mouse to customers who buy its new iMac computer following its announcement over a week ago.

While the company is famous for announcing a product and having it in stores the next, if not same, day Apple stores across the US are still without stock citing that it is "expected soon".

"You can expect once the software hits, the mouse will be available soon after", a store clerk told Pocket-lint in Apple's 5th Avenue store in New York before the software became available for download.

The update, which weighs in at 63.9MB, and 101MB when installed, will allow users of the mouse to scroll vertically and horizontally with a swipe of their finger rather than having to rely on a scroll wheel.
