On Tuesday, Apple began pushing OS X Yosemite 10.10 golden master release candidate 2.0 to developers for testing. The push comes about a week after OS X Yosemite 10.10 golden master release candidate 1.0 to developers at the end of September and also on the same day that Apple pushed iOS 8.1 beta 2 to developers.

The golden master is about the closest thing to the real public release that developers are going to get. OS X Yosemite 10.10 is expected to be released some time this month; probably around the middle of the month closer to Apple's upcoming special event. The operating system brings users a new user interface aesthetic, as well as a truckload of new features that work seamlessly with iOS 8.

Apple began asking Mac developers to begin submitting their OS X Yosemite-compatible applications to the Mac App Store last month following the release of the first GM of the desktop operating system so that users could have a seamless transition over to the new operating system.

If you're on any of the OS X Yosemite betas, or you're running the original GM, you will find this update under the Updates tab in the Mac App Store application. You can also head over to the "Software Update" option under the  menu in the Menu Bar.
