iMessages is a huge success. Almost everybody with an iPhone, iPad or iPod touch seems to be using the feature on a daily basis. Apple has today finally made a beta version of iMessages available for the Mac. The final build will be available with Mac OS X Mountain Lion which Apple plans to release this summer.
With Messages (iMessage), you will be able to chat with anyone with an Apple ID and on an iPhone, iPod touch, iPad and now even a Mac for free. All messages across all your devices will be in sync with each other.
You can download it now from here.
