Apple Releases Developer Version of OS X Lion

February 26, 2011 · by John Ponio

Finally, Apple is all set to launch their new version of OS X (pronounced oh-ess-ten, not oh-ess-ex), namely OS X Lion. For a brief version history, there was OS X Tiger, Leopard, Snow Leopard, and now Lion. This OS update brings Apple’s “App store for computers” idea from their latest Macbook Air to another level. More information and a list from their press release will follow after the jump.

There are a bunch of cool new features in Lion. One of the coolest, in my opinion, is the “Resume” feature, which basically does the same as hibernate would on a PC, but you can fully restart your computer and/or update it. If you’re a developer registered with Apple, you can download the developer version from their website.

a new version of Mail, with an elegant, widescreen layout inspired by the iPad; Conversations, which automatically groups related messages into one easy to read timeline; more powerful search; and support for Microsoft Exchange 2010;
AirDrop, a remarkably simple way to copy files wirelessly from one Mac to another with no setup;
Versions, which automatically saves successive versions of your document as you create it, and gives you an easy way to browse, edit and even revert to previous versions;
Resume, which conveniently brings your apps back exactly how you left them when you restart your Mac or quit and relaunch an app;
Auto Save, which automatically saves your documents as you work;
the all new FileVault, that provides high performance full disk encryption for local and external drives, and the ability to wipe data from your Mac instantaneously; and
Mac OS X Lion Server, which makes setting up a server easier than ever and adds support for managing Mac OS X Lion, iPhone®, iPad and iPod touch® devices.
