Changing the iPhone root password is a good idea if you have Jailbroken your iPhone, it will prevent unauthorized users and applications from doing things you certainly don’t want them to do since the password is universal on all Jailbroken phones (unless it’s changed by the user). And yes in case it was not abundantly clear, you can not change the root password on an iPhone or iPad that has not been jailbroken as the user is not accessible, neither is the command line like this.

This is a very cool feature I had no idea existed but accidentally stumbled across while on a recent flight. If you have an iPhone, you probably know that the earbuds included with it have a button to adjust volume and what not, well guess what, you can control the volume level in iTunes and QuickTime with the iPhone Earbud buttons as well! This works at least on the Unibody MacBook Pro’s, but I’m not sure if it works on the Unibody MacBook. Just plug in the iPhone earbuds to your Mac and launch QuickTime or iTunes to test it out yourself.

It’s also worth mentioning that the iPhone earbuds microphone works fine with Mac OS X too, and it makes a significantly better microphone than the one that is built in. This is particularly handy for VOIP calls through iChat, Google Voice, and Skype.

I’m a big fan of distraction free writing space, and so far WriteRoom has this market cornered pretty well on Mac OS X.

OmmWriter looks like a worthy contender though, it’s got a beautiful unobtrusive interface and is complete with a relaxing background and subtle peaceful sound effects… if that sounds a little cheesy it sort of is, but it’s actually pretty nice to write in!

.DS_Store files store folder level metadata information (such as icon placement and background pictures) for Mac OS X to understand, this is fine and dandy and you’re likely to never even notice if you’re a bunch of Macs working together. Unfortunately, these .DS_Store files can be really pesky in a multi-platform network environment, they can basically just lead to unnecessary filesystem clutter that Windows & Linux users receive no benefit from.

Thankfully, you can prevent the DS_Store files from being created entirely by executing a simple command in the Terminal.

I use the OS X Quick Look feature constantly for everything from quickly viewing pictures, movies, text files, and of course, source code. Source can be a pain to view in QuickLook because there’s no syntax highlighting by default though, but this excellent Mac plugin changes that.

A colleague of mine is a recent Mac switcher and he was complaining to me that virtual desktops are not included in Mac OS X, the irony is that they are, they just have the name Spaces (coming from a heavy Linux background, I guess the naming convention just threw him off). Virtual Desktops are a very common and popular feature in most Unix GUI’s, but as Mac OS X has included virtual desktops within Mac OS X too.

Instead of being called “Virtual Desktops” though, Apple named them “Spaces”, but the concept is identical, multiple virtual workspaces on one machine. Spaces in Mac OS X lets you have up to 16 different workspaces to work within, you can even designate specific applications to run just within a particular space, which is very handy for creating a tidy work environment.

Hey look it’s raining out of the snow! That’s something I don’t see everyday. But the Dashboard Weather widget in OS X has plenty of unique weather conditions that can be shown, and if you want to see them all you don’t need to wait until the seasons change.

Tye Campbell wrote to us with the following question: “Do you guys know how to take apart an iPhone? Specifically the 3G model, I can’t find any way to get to the display and I’d like to do my own screen replacement since mine is cracked but I have another one available to me from a water-damaged iPhone. I’m pretty patient and don’t mind learning, but I don’t even know where to begin, any tips or starting points?”

Good question! I had to take apart an iPhone 3GS recently to replace the back case, I used the guides offered by iFixIt, they are comprehensive and really walk you through accessing various parts of the iPhone including the display. The key is to have the right tools at your disposal before disassembly, otherwise you can end up in a really frustrating situation. Also be sure to track each individual iPhone part and where it comes from inside the device so that when you reassemble it you won’t have any extra pieces laying around! These guides will help you with selecting the right tools and staying organized during the iPhone repair, follow it carefully and you should have no problems. If you’re wondering how to take apart an iPhone, I would go this route:

I just came across a really useful QuickLook plugin called SuspiciousPackage that lets you inspect those .pkg package installer files that so many Mac apps and downloads come in. Using this plugin, you can determine if an admin password is required, how many install scripts are in the package file, where the installation locations of files is going to be, and if a restart is required.

Installation is simple and like any other QuickLook plugin. Download the SuspiciousPackage QuickLook plugin and drop it into ~/Library/QuickLook/ and you’ll be good to go (restart the Finder if necessary).

You can change the Mac OS X login screen background picture using a few different methods.

With that in mind, here are ways to change the Mac login wallpaper:

You can convert many different image file formats in Mac OS X for free using the included Preview application, there’s no need to download additional tools or do anything overly complex.

As of any somewhat modern version of Mac OS X, the Mac Preview app supports the following file types and will convert between any of them: GIF, ICNS, JPEG, JPG, JPEG-2000, Microsoft BMP, Microsoft Icon, OpenEXR, PDF, Photoshop (PSD), PICT, PNG, SGI, TGA, TIFF. Some of those image formats will be hidden from your default view when saving, requiring the usage of the “Option” key when saving to reveal them. In any event, converting from one image type to another is simple.

Mac OS X Server is infinitely better equipped, more stable, and just generally more pleasant than any of Windows offerings (yes I am biased, but it’s true), if you’re needing a server I highly recommend checking out Apple’s offering. Instead of shelling out the $499 for a copy though, you can get a free evaluation copy! If you’re a large corporation, small business, nonprofit organization, government agency, or educational institution, you can get a free and fully functional evaluation copy of Mac OS X Server directly from Apple. I just found out about this and I think it’s a pretty great thing for Apple to do, so if you qualify for a copy, check it out and you will be impressed.
