Apple just confirmed in its Q3 2012 earnings report that Mountain Lion is coming tomorrow. The hotly anticipated 10.8 version of OS X brings with it a host of new features, as we've expounded upon in the past. The upgrade will be just $19.99 (unless you've recently bought a new Mac -- in which case it'll be free) and will be available via download on the Mac App Store in 24 hours or less. Better start finding some disk space.Filed under: Software
