Apple Releases Lion Developer Preview 3

Apple just released a new OS X Lion Developer Preview. The update weighs at around 1.07 GB and it’s available now in the Software Update control panel. It is recommended for all users running Lion DP 2, and Apple’s Mac Dev Center seems to confirm the new build is indeed Lion Developer Preview 3, although the direct link on the Dev Center still goes back to Lion Developer Preview 2. It appears Apple is now seeding Lion DP update only via Software Update.

Mac OS  X Lion Developer Preview 3 is now available via Software Update for systems running developer preview 2 update 2.


In the past weeks, Apple released via Software Update two updates for Lion Developer Preview 2; these latest updates to Lion DP 2 are needed in order to install Developer Preview 3 through Software Update.

Update: We’re hearing the first changes in Lion DP 3 include a new boot animation, new graphical elements in the Finder’s toolbar, new desktop wallpapers and the Reading List, now enabled in Safari. The Reading List’s button sits in the bookmarks bar, and can be enabled from Safari’s Preferences. Reading List items don’t synchronize via MobileMe for now nor do they appear in the bookmarks manager once saved, but there’s the possibility Apple will make them compatible with MobileMe in the future. MacRumors has more screenshots here.


Update #2: It’s All Tech has a detailed list of changes and screenshots from Lion Developer Preview 3:
