hacker can hack the battery module and stop the charging of your Mac

What Apple Macbook Battery Hacking is About? 
Charlie is just someone who wants his Mac to be safe from hackers. He is not out there to make Apple feel embarrassed. He wants Apple to go one step further, and make its devices foolproof. “I don’t want to be their adversary. I want to have them fix stuff — and I want them to get better“, Charlie said.If you have a software problem or if someone hacks your device, you can reboot and have your system running like a horse again. But what to do when someone can affect the hardware with the use of a software? Charlie Miller has found a way to shut down the charging system in your Mac by playing around with the software. 

 How Apple Macbook Battery Hack Works? 
There is a dedicated system for charging your laptop. There is a constant interaction between a computer and its battery module. The battery module is responsible for calculating how much more battery the computer needs, when to cut the power off. And for running that battery module, Apple has given software.

This software has passwords, so that a user does not rupture it in any way. Charlie Miller just goggled for those passwords and found them. He hacked his Mac, entered the passwords and changed the software according to what he wanted it to do. And now he can do many queer things.He can change the software in a way that the computer doesn’t know whether the battery is connected to it or not. And your Mac won’t get charged, and you will just keep checking the battery wire connectivity to your Mac. And will keep checking if the battery is plugged in properly to the electric socket. 

Implications: If someone is heartless enough, he can force your Mac to blow. And it’s not in theory. If someone changes the battery software in such a way that the computer keeps getting charged, then it can blow up, leaving you with burns.
 
Solution: 
The solution is that Apple should change the default passwords which are keyed in when the Mac is manufactured. Charlie presented his hacking technique at the Black Hat security conference. And he thinks that changing the passwords will stop this kind of Mac hacking. So, if next time you are going out to buy a Mac, then do open your wallet with a pinch of concern.

Run Your OS X Lion With One in Six Macs

One-in-six Macs now runs Apple's latest operating system, a Web metrics company said last week. According to California-based Net Applications, Mac OS X 10.7, aka Lion, accounts for 1 percent of all desktop operating systems that were used to connect to the Internet last month.The total usage share of Mac OS X was 6 percent, said Net Applications.Apple released Lion on July 20 to the Mac App Store, where the download-only upgrade was priced at $29.99. Two weeks ago, Apple also started selling Lion on a USB flash drive for $69, aiming that version at users who lack a broadband connection to the Internet.

Lion's online usage nearly matched that of Mac OS X 10.5, or Leopard, the edition Apple released in October 2007. At the end of August, Leopard's share was 1.2 percent.Mac OS X 10.6, aka Snow Leopard, remained the most widely-used version of Apple's desktop operating system, with an overall share of 3.5 percent, or 57 percent of all Macs.Snow Leopard's share fell by half a percentage point in August as users migrated to Lion.Mac OS X is still dwarfed by Microsoft's Windows, which powers almost 93 percent of all desktops and laptops, said Net Applications. (See also "Running Windows on a Mac: Lion vs Windows 7 Shootout.")

With August's data, Net Applications revamped the way it tracks operating use by separating smartphones and tablets from conventional personal computers, a change the company said was prompted by the rise in mobile browsing.Net Applications calculates operating system usage share with data obtained from more than 160 million unique visitors who browse 40,000 Web sites that the company monitors for clients. More operating system usage data can be found on the company's site.

Apple launching13-inch MacBook Air: All about style and speed, too

It's the perfect combo of looks and technology.
Usually, when I'm reviewing laptops, I wind up with a variety of caveats that weed out potential buyers for whatever I have in hand. The screen isn't big enough. There's not enough RAM. The processor is outdated. The keyboard is spongy.

I'm having a tough time finding similar flaws in the new Air, which Apple rolled out last month when it released OS X 10.7, better known as Lion. Part of what makes the Air such a great little laptop is Lion. Part of it is the hardware itself. Put those two pieces together and you have a solid nexus of modern OS and top-notch hardware that makes this laptop a real pleasure to use.

And I'm saying this as someone who always -- always -- defaults to a larger screen, aiming for as much high-resolution real estate as I can get. Preferably with the fastest processor available. (Right now, my personal laptop of choice is the top-of-the-line 17-in. MacBook Pro.
Still, I find myself realizing I'd be fine with the 13-in. MacBook Air I've been using for a couple of weeks now. And as someone who had one of the first-generation Airs, all I can say is: Ain't evolution grand?

The new Air -- I reviewed the larger, $1,299 model -- is cutting-edge stylish, lightweight (less than 3 pounds), speedy (almost twice as fast as its immediate predecessor, thanks to a Core i5 Sandy Bridge chip), well-built (aluminum unibody construction), and a showcase for the new Lion OS. I'm already a huge fan of full-screen apps and swiping back and forth between desktop spacesusing Mission Control gestures. With the Air, Apple's melding of desktop OS and mobile iOS really shines.
As a friend noted, "It's like having an iPad with a keyboard."The Air lineup

There are four models in the Air lineup: Two feature an 11.6-in screen, and two come with a 13.3-in. screen like the Air I'm using now.Prices start at $999 for the 11.6-in. model with 64GB of storage and 2GB of RAM. If you want a really lightweight, netbook-like laptop, then this is your model. I find the screen size too small, even though the resolution is 1366 x 768 pixels. It's too much like looking through a mail slot.

Because Apple has killed off the old white plastic MacBook, this is now the entry-level model for Apple laptops. If you can live with the screen and limited storage, it's a good choice. Do yourself a favor, though, and bump up the RAM from 2GB to 4GB. (You can't install extra RAM yourself so you have to do this when you buy.) That adds $100 to the cost and edges you closer to the $1,199 model, which includes 4GB of RAM and comes with 128GB of storage.

The extra RAM is important, too, since all of the Airs use the integrated Intel HD Graphics 3000 chipset. If you have 2GB of RAM, you'll have up to 256MB of video RAM available; moving to 4GB of RAM allows the integrated chip to use up to 384MB of video RAM.

Storage is solid-state on all four models, ranging from the aforementioned 64GB (too small) to 128GB (probably fine for most people) to 256GB (what I'd want). Using flash storage is a smart move for Apple because it allows for a thin form factor and because it speeds up everything you do.
