Now that you've updated your Mac to OS X Mountain Lion it's time to start checking out some of the new features. iMessage now comes stock in Mountain Lion and makes it easier than ever to stay in contact with the people that matter most across your iPhone, iPad, iPod touch, and now, your Mac.
iMessage in OS X Mountain Lion lets you pick up conversations on your Mac right where you left off on your iPhone, iPad, and iPod touch. The best part is it's completely free and will work with anyone who has iMessage activated on their iOS or OS X devices.
If you signed into your iCloud account when you installed OS X Mountain Lion, you're probably already signed in and good to go so just skip this step. If you need to sign in manually, you can do so by following these steps:
Now that iMessage is replacing iChat in Mac OS X, you may be wondering how to send instant messages without having to download another third party application. iMessage will give you the ability natively just like iChat did.

If you've got iPhones, iPads, and iPod touches, you can also set them up to use iMessage as long as you're running iOS 5 or later. You can check out our guides for iPhone, iPad, and iPod touch as well if you need help.
