Sources suggest that hardware upgrades would on Tuesday of the operating system software release will follow on Thursday: We have \ a developer's perspective on what 's new

Apple expected to start Mac OSX 10.7 - code named "lion '- as soon as next week, according to reports, the company has instructed its stores, machines prepare for the upgrade by saying that Sunday.

Machines in the store with additional RAM if possible to upgrade from OSX 10.6 ("Leopard ') fitted.

The upgrade will cost $ 29.99 or ? 20.99 in Great Britain. Lion requires at least 2 GB of RAM and an Intel Core 2 Duo, Core i3, i5, i7 or Xeon processor - which means it is compatible with Apple computers except the Mac mini from the end of 2006.

There are also rumors that Apple has new versions of its MacBook Air notebook slimline, can possibly start on Tuesday - when it usually publishes hardware - the software upgrade that is only being useful for machines already running 10.6, the following delivered Thursday - the day when Apple usually free operating system upgrades.

The developers have already begun with the "Golden Master '(final) pass version of Lion since early July, and many were their discoveries of errors or delicacies on Twitter with the word" ROARDACTED "- a reference to" roar "and" edit "- tag their findings.

Lion includes a number of changes that have been on the IOS operating system on the iPhone and used iPad taken, including optional "reverse scrolling" (in which moving the mouse down scrolls the screen up and vice versa) to other , major changes.

We asked for experience, and had this response from a developer (who has to remain anonymous) who tested the seeds of the Golden Lion to the master.

He said: "One thing that 's really changed for the Mac is security that they'. Re bring the highly successful sandbox [where code can only run in a controlled environment, with highly restricted access to machine resources] from IOS to the Mac. Can I get a time when all applications have to be downloaded from the Mac App Store ? Maybe.

Multi-Touch gestures

What it is: A system borrowed from the iPhone and iPad.
Developer's perspective: "Brilliant. Four finger swiping between eg an application in full screen and swiping left of the desktop is a dream. Really smooth implementation, already feels normal \."
Inverted scroll. How do you think 'd, a little difficult getting used to, but it makes perfect sense 15 minutes in. The mental switch is already happening now, and Snow Leopard feels wrong.

Full-screen applications

What it is: Expand each application so that it fills the screen - so no distraction from others.
Developer's perspective: "At the moment I 'write m this in full screen mode. There is no menu bars, which feels at first a bit like getting into a lift without keys, a bit intimidating, again something you get used easily. It 'sa gold mine productivity not able to see the blue glow of the Twitter / Sparrow app, or sometimes with a look at the clock. autosave, the fear goes to the rescue every so often away. "

Mission Control

What it is: Combines full-screen applications, Dashboard, Expose and Spaces in a new feature that gives you a bird 's look at everything on your system.
Developer's perspective: "Four Finger gestures Swipe up on the trackpad and you 're in Mission Control. If you' re working on a few other things at the same time it is not beautiful. Perhaps you have a lot of full-screen applications on have want to go out and get an overview of what you re 'to get to. The ability to have multiple desktops get a clean start for something that is cool. "

Mac App Store

What it is: Now even more integrated into the system, and always an important source of applications to download. You can still get apps by downloading from the Internet, though.
Developer's perspective: "There is nothing really exciting here is standard with the operating system as something that you answer download. Pair of features in app purchases and put messages, but I 'm yet to see them in action."

Launchpad

What it is: a new, full-screen home for all applications on your computer, brought up by clicking an icon in the Dock disappearing open window to a full-screen display will be replaced by all your applications.
Developer's perspective: "Apple are working hard to move away from traditional finder [File Browser] use on the Mac. You 're more likely to open files of the application it belongs to pursue against them in documents. Launchpad is a shift in that direction. On looking for an app that isn 't the dock already? With Launchpad, you' re just a click away form they look at all. No doubt, it \ see's a lot nicer than using the Finder window. The Springboard apparently mimics the IOS devices, so it 's easy to use and intuitive. "

Resume

What it is: Start the machine again in exactly the same place that it switched off - the conservation status of the documents.
Developer's perspective: "This works well enough, although release is still buggy as the GM. A lot of times you open Quicktime Player and get all the things that ve you 'open ever opened simultaneously. Four fingers move down on an app will give you thumbnails of recently opened items. "

Autosave and versions

What it is: Documents that are created by certain applications are automatically stored in fixed periods of time. You can return to a previous version or compare.
Developer's perspective: "Does what it says on the tin. I 've not been able yet to test functionality versions."

Airdrop

What it is:on-the-fly peer-to-peer wireless network between two Macs.
Developer's perspective: "Have been unable to test this yet."

Post

What it is: redesigned with a three-pane interface from which borrowed iPad. Also, the advanced search and conversation threading.
Developer viewpoint:"I bought Sparrow from the Mac App Store because it was minimal. With Lion, African clawed frog mail me again as a user. Beautiful minimal interface, immersive full-screen experience and great new search features."

Bye bye scrollbars

What it is: a radical change to the interface. (You can also resize windows from any part of the site, because Windows has offered for years.)
Developer's perspective: "Yes, looks good, without them you can programmatically force them to stay there, such as Firefox now she has five permanent, but that will certainly change in coming weeks."
