Mac OS X Lion Developer Preview 4 is Now Available to Download
Mac OS X 10.7 Lion Developer Preview 4 has been released for developers to download from Apple’s servers. The new build number is 11A480b and includes a variety of changes that were shown at WWDC 2011, and was announced alongside iOS 5 beta 1 and iCloud.
Developers can download the update directly from Apple through the Mac Dev Center. If you’re currently running Lion DP3 you can also download it directly through Software Update, although this does not seem to be available to all users yet.
