Apple releases first Developer Preview of Mac OS X Lion

Apple have announced the first developer preview of Mac OS X Lion on their website. They have also launched a preview site outlining the features users can expect from Lion when it becomes available in the summer.

Apple today released a developer preview of Mac OS X Lion, which takes some of the best ideas from iPad and brings them back to the Mac for the eighth major release of the world's most advanced operating system. Lion features Mission Control, an innovative new view of everything running on your Mac; Launchpad, a new home for all your Mac apps; full screen apps that use the entire Mac display; and new Multi-Touch gestures. Lion also includes the Mac App Store, the best place to discover, install and automatically update Mac apps. The Lion preview is available to Mac Developer Program members through the Mac App Store today, and the final version of Lion will ship to customers this summer.

Among the new features outlined on MacRumors include:

  • Mail, 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;
  • 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;
  • AirDrop, a remarkably simple way to copy files wirelessly from one Mac to another with no setup;
  • 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.

Apple are aiming to bring some innovations found in the iPhone and iPad, and bring them back to the Mac. One of of the new features is multi-touch, so Apple is bringing multi-touch to Mac OS X Lion. Apple has tried long to bring multi-touch to the Mac through trackpads and mouse.

The App Store will also be making an appearance on Mac OS X Lion. With downloadable apps, like Angry birds, you'll be able to play games, browse apps, read books and many more. The Mac App Store will be separate from the iPhone, iPod and iPad store, but will be used just like it.

Lion will also include home screens, just like the iPhone and iPad. Having a few different desktops with icons across your home screen, so you can access your apps. The App Store will feature top paid, top free and many other categories like the mobile App Store has.

Lion will bring full screen apps to the desktop, just like in iPhoto, so you can focus on what you're reading or playing. With full screen mode, you want to find your apps and screens easier, well Lion is bringing a new feature called "Mission Control", where you can view all your opened screens with a single click, making it easier to open or browse through screens.

time to pay for your sp sheeple

I know, I know. Microsoft have just recently returned to reasonable version numbering of their software in Windows 7. There was a lot of confusion between 95, 98, NT, 2000, XP, and Vista but they are back on track now.

So I see how Apple calling their OS "OS X" and the major versions of OS X being 10.1, 10.2 etc, with the "service pack" level being 10.1.x can confuse you. You have had a lot of version number abuse from MS.

Oh, and in Apple "service packs" it isn't atypical that we see new features (like the App Store that was added to Snow Leopard). MS doesn't seem to bother with any significant changes in their Service Packs...just a collection of their ongoing weekly security patches (which are always a joy to install for the old weekly system reboot).

This.
The guy obviously has no idea of what he's talking about. Stay with Windows, then.

Bleh iOS... what's the point of the dock if the desktop is like that. I guess if you have an "App" open, but at least have the dock disappear or something when the desktop is up. How redundant.

This sounds like a service pack if I have ever heard of one... A few new features to OS X but nothing new industry wide. OSX has become boring and not intuitive - at least not to my likes. I find I can get more done, easily and quickly now that Windows 7 was released.

Yet another ignorant poster who doesn't understand that service packs don't add new features. And some of these features that they are talking about are fairly unique in the OS market.

Yep, I believe most of these are just Paid Service Packs.. It's the same OS just with different codes and a few new features.. And this one just trying to look like a non-touch iPad.

Uhhh no, "service packs" are 10.0.x updates

Yes, because 10.0.0 is basically the same thing as 10.7 or whatever Lion is... just bug fixes and little features. /s

Tell me, how is that any different from a new Windows version?

If you don't know what you are talking about, then just don't talk.

Sometimes it's better to just not argue with these people, you know.

That new version of File Vault sounds like a cyber-criminal's wet dream. As I understand it, even with the current version, the FBI has to call in a special team from Canada to recover data from any Macs that they need to access. I can only imagine the trouble they will have with this!

Seriously? That's pretty humourous.

Resume just sounds like sleep mode on Windows.

You must have failed reading comprehension. Resume has nothing to do with sleep mode. It restores your apps to exactly where they were when you close and restart them, or when you reboot your computer (like when installing system updates or software that requires a restart). Does sleep mode do either of those things? And Macs have had sleep mode for ages (and had it working correctly for a good bit longer than Windows machines).

"Sleep" actually works w/o any problems w/s/e on my MacBook. Can't say the same about my new Windows 7 thinkpad at work, or my home ASUS desktop... Works after a clean Windows 7 install for about a month and then for some reason has problems (i.e., slow downs after coming back from sleep) etc. Seems MS and their OEMs still can't figure it out.

A new mail client? So what.

An email client is something you will yourself using daily, so a new email client is awesome for everybody.

Now, Snow Leopard has a sleep mode like Windows already and it did way before Snow Leopard. You're not talking about the true Resume option here.

Even if it just saves the state of the application and pauses it when would you ever need that?

I fail to see what new features a new e-mail client would have that would be any more better than the current e-mail clients already out there.

Unification of OSX and iOS has just started. Hope AirGrop immediately comes to the iPhone and iPad with iOS 5. Cuz right now it's really troublesome to transfer a simple photo to your desktop; it needs cable connection or fire up a ftp client/samba client over Wi-Fi.

And no, Dropbox or similar is not the same with AirDrop.

Autosave is amazing! you open a document, type something, close your application, reopen it and its all there, didn't even ask to save it!

Versions works beautifully, its like a time machine for every single document you create! Hopefully this will be an OS X feature that developers will jump in and support immediately. no more losing data.

What feels weird to get used to is the scrolling! its work like the ipad, so smooth and scroll bars appear only when you scroll! however it feels weird to move you finder up to get it to scroll down. Its something to get used to i guess
