Apple has released a small update for OS X Mountain Lion Developer Preview 3. Anyone running the latest OS X 10.8 Dev Preview can launch software update to grab the update, which includes a new Do Not Disturb feature for Notification Center. This effectively hides all banners and notifications from showing on the desktop so as not to distract you. They'll all be neatly stored and organized within the Notification Center pane when you're ready to review them. We're not seeing any other obvious changes, but if you catch any, hit us in the comments.
Apple has just released a new OS X 10.8 Mountain Lion Developer Preview about a month after the last release. Dubbed Mountain Lion Developer Preview 3, build 12A178q is the third beta release of the company's next major desktop operating system. Developers can grab a download redemption code in the Apple Developer portal, which will be used to get the update from the Mac App Store. OS X 10.8 Mountain Lion will be publicly released late this summer, but anyone with a Mac developer account can get access to the Developer Previews immediately. Release notes after the break.
