Apple Releases OS X 10.7

| Lion

Apple announced the immediate availability of OS X 10.7 Lion on Wednesday. Lion replaces Mac OS X 10.6, or Snow Leopard as Apple’s most current Mac operating system and marks the first time the company has distributed its OS only as a download.

Lion is available only as a download at Apple’s Mac App Store and the company isn’t offering a version on DVD as it has with previous version of OS X.

The new version of OS X borrows several interface features from iOS on the iPad such as multi-touch gestures for navigation and app selection, an iPad homescreen-like Launchpad for organizing apps, and full screen view for individual apps.

“Lion brings many of the best ideas from iPad back to the Mac, plus some fresh new ones like Mission Control that Mac users will really like,” commented Apple CEO Steve Jobs.

The new OS also takes advantage of Mission Control for quick access to other applications and application windows, includes system-level support for the Mac App Store, includes a redesigned Mail app, offers improved disk encryption option, document auto-saving, document versioning, and more.

OS X Lion is priced at US$29 and is available as an upgrade for Mac OS X 10.6.6 or higher at Apple’s Mac App Store.

Start up disk?


Start up disk?

You can make your own. (Jeff/TMO may want to clarify.)

Go to the Applications folder after downloading the Lion installer. Right-click (option click) on the ‘Installer Mac OS X’ app in Applications (it has the Lion pic on it), and select ‘show contents’. Under contents, scroll down to the SharedSupport folder. Locate ‘InstallESD.dmg’ file and make a copy either on your DVD or on a USB flash drive.

You can find a somewhat out-of-date set of instructions here, but this appears to have referred to the gold master release.

Cannot vouch for how well the disk works.


Also it creates a recovery partition when it installs, so most uses of a startup disk are substituted by that partition, unless your whole hard drive dies.


unless your whole hard drive dies

  and then you’re FUBAR

At least Apple has realised this, and is now going to offer a “Bootable” Installer on USB.

(I’m assuming the USB stick will be bootable, like the MacBook Air)

I wanted to buy Lion, but I couldn’t find it at the Amazon App Store.
