We're getting numerous reports via the tweets that iOS 7 wasn't the only beta Apple OS to receive an update today. OS X Mavericks is also being treated to a new beta release; unfortunately, there's nothing visible on the Apple Developer Center right now that shows either the download or any release notes.
However, our sources tell us that visiting the App Store on your favorite OS X machine that's running Mavericks should show you that beta 2 is now available for download. And let me guess it probably contains "bug fixes and improvements."
As if updates to iOS 7 and OS X Mavericks isn't enough, Apple is also making updates to Xcode 5 and OS X Server Preview available today. Get thee to the developer center now!
