The GM release of iOS 4.2 is now available to download through Apple’s Developer Program. GM stands for Golden Master, which generally means the software release is ready to ship. The iOS 4.2 update is hotly anticipated for iPad owners in particular, since it will bring multitasking abilities to the device. The update also installs on the iPhone 4, iPhone 3GS, iPhone 3G, and the 4th, 3rd, and 2nd generation iPod touches. Installing the iOS 4.2 update requires iTunes 10.1 as well.

If you’re an iOS developer, head on over to Apple’s iOS Developer Center to grab the iOS 4.2 GM build 8C134.

For those who aren’t developers, the wait to download and install iOS 4.2 is not going to be long. It’s expected that the newest version of iOS will be released to the public within a week or two, which would match the November release date that Apple scheduled earlier in the year.

If you need to open and expand rar files in Mac OS X, you can unrar files with two free utilities available for the Mac. Not only will either of these apps quickly open and decompress .rar files, but it also has the ability to restore corrupted and missing archives using par files. Archive restoration using par2 is often essential when working with torrent and newsgroup downloads.

The iPhone Dev Team has released RedSn0w 0.9.6 in it’s second beta form for both Windows and Mac platforms. There are two main reasons you’d want to use redsn0w. The first is for Windows users, since redsn0w allows you to use custom IPSW files. The second reason is that redsn0w allows you to use custom boot logos on iPhone 3G, iPhone 3GS, and iPod touch 2G, assuming you have qualifying bootrom, this is obviously just a cosmetic feature.

Update 11/23/2010: redsn0w 0.9.6b4 download has been released.

The Dev Team notes that you should not use redsn0w if you have used the ultrasn0w unlock in the past, since you may lose the carrier unlock if you were to upgrade to iOS 4.1.

Download Redsn0w 0.9.6b2

These are direct download links for Windows and Mac OS X:
0.9.6b2 for Mac OS X
0.9.6b2 for Windows

Remember that if you need to build a custom IPSW file for redsn0w to use, you’ll have to do so with Pwnage Tool. Otherwise, if you need to access original IPSW files, you can download iPhone firmware & IPSW or iPod touch firmware from two large lists.

The redsn0w 0.9.6b2 jailbreak uses the same exploit as limera1n as opposed to the older DFU mode exploit. If you just want to jailbreak your phone and you’re not concerned with unlocks, I would recommend going with greenpois0n or limera1n, they are a bit easier.

You can have your iPhone display the character count of text messages by enabling an option within the settings, here’s how to do this in iOS:

Zombie Snow White on a MacBook? Yikes, this is rather horrifying but very fitting for Halloween.

Everyone has probably seen the Snow White decal stuck on the back of a MacBook by now, if you’re a Disney & Apple fan it’s an appropriate tribute to both, and, well, this is a very creepy twist on that. Would I put it on my MacBook? No, I don’t think I would, but then again my personal favorite decal is The Giving Tree, which is a whole lot friendlier. To each there own.

Happy Mac Halloween everyone! And thanks to CJ for sending this picture in.

Oh, and remember it’s not too late to grab a pumpkin and carve an Apple logo pumpkin or to get a creepy iPad wallpaper.

Here’s a nice trick if you need to continuously observe your Macs system usage, including disk usage, CPU, and load average. The great thing about this iostat trick is that it updates constantly, allowing for realtime monitoring of system performance, which can be extremely helpful for performance testing and tracking down various processes or activities that are resource heavy.

If you’re a writer, student, or blogger, the new MacBook Air might be your portable dream machine. For low CPU intensive tasks, the lightweight notebook boasts a battery life that is significantly better than the advertised time of 5 to 7 hours. AnandTech did some extensive reviews of the new MacBook Air and found the battery to last a staggering 7 to 11.2 hours for the 11″ MacBook Air and 13″ 2010 models respectively:

As glorified typewriters, you can’t beat the battery life offered by the MacBook Air. Light web browsing, document creation and music playback have minimal impact on the Air’s battery life. In fact, we actually beat Apple’s battery life claims in our light tests. The 11-inch Air delivers nearly 7 hours on a single charge and the 13-inch managed 11.2 hours. For a writer, you can’t do better than this.

The results were found with screen brightness at 50%, connected to WiFi, playing an MP3 in iTunes, and with no Flash player loaded while browsing the web. Here’s the chart of the new Air against other MacBook and MacBook Pro models:

In the Halloween spirit, here’s a really creepy iPad wallpaper of a hand appearing behind foggy glass. Click on the image for a full size 1024×1024 version (hosted at imgur).

For whatever reason this picture reminds me of The Ring, ahh!

This is a comprehensive download list of all the firmware files for iPod touch 2G, iPod touch 3g, and iPod touch 4G, with IPSW from 3.1.2 to the current 4.1.0. All of these IPSW files are hosted with Apple and direct linked to their servers. If you have an iPhone, you can download iPhone firmware instead.

iPod Touch Firmware / IPSW Downloads

We are not hosting the firmware files, they are hosted with Apple. It’s best to right-click on the .ipsw link you need and save it directly to prevent your browser from trying to decompress the firmware package on its own.

Here’s a cool MacBook mod, a user attached a black MacBook bezel on his white MacBook, creating an Oreo MacBook. I have a white MacBook and always imagined doing this and swapping in a black keyboard too after seeing the MacBook Pro come out with their black bezels and keys. Definitely a great mod and I think it’s one of the more creative Mac setups around.

I’m pretty sure this picture belongs to an OS X Daily reader, another one of our readers sent it in saying he found it following comments on an article, but I haven’t been able to track it down. If this is your MacBook and you want credit, please let us know!

Update: The Oreobook belongs to Joel Adria, you can follow the progress of creating the MacBook hybrid at his website.

Microsoft Office 2011 for Mac has been rated as the best version of Office to ever come to the Mac platform. If you need the powerful office suite, there’s no better place to buy than through Amazon, thanks to their generous discounts and free shipping.

Does your Mac need more memory? How can you tell? Often when a Mac needs more RAM things will start slowing down and you’ll suffer a noticeable performance hit. This can impact everything from the speed of the computer, to how long it takes to launch apps, to sluggishness when interacting with apps, and more. If you experience any of those types of issues, it could be RAM constraints, but rather than guess, let’s actually learn how to check memory usage.

Here’s a 3-step process of how I determine if a Mac user needs additional memory. Using this method you can determine if you need more memory for your Mac too, so let’s follow along.

Everyone knows that the delete key removes letters and numbers, but it does so one character at a time. That means if you want to delete and entire word, you have to hit the “Delete” key over and over again until it’s gone, right? Wrong! There’s a super handy trick that lets you delete complete words at a time and it’s super easy to use and remember!

To delete an entire typed word at a time, simply hold down the “Option” key while using the Delete key. This will delete a complete word at once (or any other continuous string of characters that are not interrupted), so if you keep hitting Option+Delete it will continue to delete more words.

Do you want to buy Parallels 6 for $13.99, including free shipping? This looks like a one day only deal, but what a deal it is.

How to score Parallels 6 for $14 $17.99

Update: Parallels 5 for Mac on Amazon is now $17.99 after rebate. This is still a great deal because it is still eligible for the free upgrade to Parallels 6 which is a huge discount!
Here’s the deal, Parallels 5 is offered on the Amazon Daily Deals site today at a reduced price of $33.99, and it includes a mail-in rebate of $20, bringing the price to $13.99. But guess what? Parallels offers a free upgrade guarantee on version 5 purchased until November 30, 2010, meaning you get a free upgrade to Parallels 6.

Here’s what you’ll need to do:

• Find and buy Parallels 5 for Mac on Amazon for $33.99
• Fill out the $20 rebate form with the developer (the rebate code comes with Parallels 5)
• Save your Amazon receipt, then register and activate Parallels at https://www.parallels.com/account/ within 30 days of purchase
• Now go to http://www.parallels.com/keyfor6/request/ to fill out the free upgrade to Parallels 6 request. You will need the version 5 activation key and a digital copy of your Amazon invoice (taking a screenshot or digital picture of the Amazon receipt should work)

You must fill out the form by November 30, 2010 to get the free upgrade to Parallels 6. Parallels says that claims can take up to 6 to 8 days for processing, but user reports from the prior deal we posted indicate they process claims much faster than that.

Oh and if you’re wondering whether Parallels 6 is worth it, I’d say indeed it is, particularly if you’re a gamer. The gaming performance of Parallels 6 within Mac OS X is pretty amazing, here’s what ArsTechnica had to say about it:

The graphics can be jacked all the way up, and there’s no laggy latency—that’s pretty incredible

You can check out running Windows games in Parallels 6 for more. Apparently just running Windows on top of Mac OS X is pretty speedy with it too.

If you miss out on this deal, you can still use the rebate, Amazon discount, and upgrade guarantee to get Parallels 6 for cheap, but the price seems to fluctuate a bit. The rebate and upgrade guarantee are valid until November 30, 2010.

Select your iPhone, as long as it’s not white. Has the White iPhone 4 been discontinued? The device is now missing from the Apple Store’s iPhone purchase page, which has led to speculation that the white model has been discontinued entirely.

The prevailing theory is that Spring of 2011 is close to what is typically the launch date of a new iPhone, thus Apple won’t produce a white model of the current iPhone 4. If this holds true, the white model may appear as an iPhone 5, or whatever the naming convention goes with, iPhone 4G is perhaps just as likely.

Earlier this week, the White iPhone 4 release date was pushed back to Spring of 2011, which included an apology from Apple.

If you accidentally sent a file to the Trash can on a Mac, you can undo that file or multiple files movement into the Trash with one of two easy tricks to essentially undo that file action.

You can use either method below to accomplish this, with the “Undo” command working if the trash action was the most recent, otherwise you’d want to rely on the “Put Back” method to restore a files location and undo the Trash move.

Apparently Apple ran the gamut of the entire animal kingdom while deciding on a creature to brand their new operating system with. After taking a look at some of the options, they finally settled on Mac OS X 10.7 Lion.

OK not really, if you’ve followed Apple whatsoever you’ll know they’ve had a cat theme for a while now, but this is a rather funny picture from the Apple joke site Scoopertino.

You can change the placement of icons on your iPhone or iPod touch much faster by moving them around directly within iTunes.

• Plug your iPhone, iPod touch, or iPad into your Mac or PC
• Launch iTunes
• Select your iPhone
• Click on the ‘Apps’ tab within iTunes
• Drag icons around the visible homescreen

As long as you have “Sync Apps” enabled, your new iPhone home screen and icon placement will be saved. I find this much easier than trying to rearrange lots of icons on the small touch based screen.

This even works with jailbroken devices, although the Cydia icon was stubbornly quirky after the limera1n download and kept snapping back to it’s original placement on an iPhone 3G.
