Apple officially announced that the next major version of OS X will be shipping this summer. This would be version 10.8.0 if your geeky that way and it’s called Mountain Lion. Apple has a sneak peak of the Mountain Cat. There is a preview available to download for developers. Messages, which is the new Chat version in iOS, will be basically replacing iChat on the desktop. The beta version is available to download for everyone.
Macworld has a big guide to what’s new. Gruber was invited to the product briefing of Mountain Lion and has a great write up over at Daring Fireball. And there’s an interesting post on the new security feature called Gatekeeper over at the Panic blog.
