Mountain Lion is here! Apple announced that the new Mac operating system, OS X 10.8, will be available to the general public tomorrow, nearly a month since it debuted at Apple’s Worldwide Developers Conference in June.

At the time, Apple told the crowd that Mountain Lion would “ship” in July. The company has thus far gone the whole month without a peep on when we’d be able to download the latest OS, until yesterday when it accidentally opened up the “Up-to-Date” portal.

Apple promised that anyone who purchased a Mac computer on or after June 11 would get a free version of Mountain Lion and could request that free version through the Up-to-Date portal. That website was made available yesterday, but then quickly taken down.

The operating system comes with 200 new features, which were shown off at WWDC. Those include an updated version of Apple’s Safari Web browser, voice dictation, Twitter integration, and a new notification center. One of the biggest changes is that Mountain Lion will now support iMessage, the messaging system that allows those with iOS devices to effectively text for free.

Last quarter, the company  sold four million new Macs. At WWDC, Apple said that six million people overall use Macs, 40 percent of whom run OS X Lion, the latest operating system available to date.
