Apple released a Developer Preview of Mac OS X 10.7 Lion, included are many features that were seen in the October “Back to the Mac” event, in addition to several new ideas.

Highlighted features of Mac OS X 10.7 Lion Preview

Many Lion features are borrowed from iOS:

  • Launchpad – iOS style app launching and folder management
  • Full-screen apps
  • Mission Control – Encompasses Dashboard & Expose as a super window manager
  • Gestures & animations – extensive multi-touch support
  • Auto-Save
  • Versions – built-in version control of all documents, in an interface similar to Time Machine
  • Resume – saves your Macs last state after reboot, all apps, sites, and documents included
  • Mail 5 - very similar to Mail on iPad
  • AirDrop – instant wireless document transfers
  • Lion Server – now built into Mac OS X Lion, no longer a separate OS

The Developer Preview requires a 64-bit Core 2 Duo processor or newer, and you must currently be running 10.6.6 in order to download the preview release.

Downloading & Installing Mac OS X 10.7 Lion Developer Preview

If you’re a registered Apple Developer, go to Mac Dev Center to download your copy of Mac OS X 10.7 Lion Developer Preview, it weighs in at a hefty 3.6GB.

Each installation of Mac OS X Lion seed requires a redemption code from the Mac Dev Center, preventing unauthorized users from running the developer release software.

    I am tempted to buy a developer account just so I can run the preview. Is it stable? Any word?

    • Will says:

      It’s a developer preview, so expect things to be stable enough to use but buggy enough for it not to be a public release.

      Anyone can register to be a Mac Dev for $99 and then download and install Lion Preview.

      • Annon says:

        Or just… you know… not pay, then download it for free from darker crevices of the web like everybody else.
