NameChanger is a free app solution to quickly and easily batch rename files in Mac OS X. It has all the features you’d expect in a batch renaming app, and you can replace occurrences of text in filenames, use wildcards, append text or characters, add dates, make files sequential, and even remove characters, just select your options and you’ll see a live preview as to what the new names will be.

Using it is very easy, you can import files from the app, or use the standard drag-drop support feature. Adjust your parameters for renaming the file(s), and when you’re satisfied with the output of how you want the files to be renamed, all you need to do is click a button and away you go, the files are renamed quickly. There’s even a live preview of the changed names so you can be sure you get things right before initiating the changes.

You can create a folder that is hidden from the default Finder GUI view by taking advantage of Mac OS X’s unix underpinnings. That probably sounds a lot more complex than it is however, and it turns out it’s actually really easy to make a completely hidden folder on the Mac.

This walkthrough details how to both make the hidden folder, and then how to access it yourself in Mac OS.

If you want to discover the last time a specific command was used without actually executing it, follow this format at the command line:

!sudo:p

The above example will print back the last usage of the ‘sudo’ command without actually executing it, which is very useful in some situations (like the situation below, where the last time the sudo command was used was deleting everything recursively!). You will see the last used command printed directly below:

$ !sudo:p
sudo rm -rf /var/logs/*

This works with anything, even incomplete commands. Can’t remember that obscure command you used last week, but you know it started with a t? No problem!

!t:p
might print something like this:
time grep -c and rewin.sh

It’s important to note the :p modifier at the end of the command is what is responsible for printing out the command rather than executing it, which is the default behavior for the bash history command ! so if you had just typed !p it would execute the last time a command beginning with ‘p’ was executed, but !p:p will print out the command minus the execution.

I know what you’re thinking, you’re asking yourself “What would Steve Jobs head look like if it was carved out of mozzarella cheese?” right?

Well, here is your answer, from The Cooks Den.

Amazing huh? Someone carved that out of cheese, who would have known that is possible?

Ok, so we like Steve Jobs, and we like mozzarella cheese, so maybe this works out just fine?

I don’t know about you, but it kind of makes me want pizza, and a new Mac.

The resemblence is pretty good, huh?

Anyone good at carving cheese? I don’t even know where to begin.

What would happen if you tried to use the iPad as a skateboard? Well this is the internet, so of course someone asked that question, built an iPad skateboard, and then attempted to ride it, all while filming. File this under the stupid entertainment category, and thanks to 9to5mac for discovering the video. Spoiler: the iPad doesn’t survive.

“The operation can’t be completed because an unexpected error occured (error code 0).”

You’re likely to see this error when you are attempting to copy files to an external hard drive that is formatted as FAT. FAT32 is a Windows file system that can be read and written to by Mac OS X.

The problem with FAT32 format is that they can not hold file sizes larger than 4GB, so if you are trying to copy a file that is larger than 4GB to a FAT32 formatted drive you will immediately be presented with the ‘error code 0’ message.

Where in the US are the highest concentrations of Apple users? A report on Fortune shows us. Here are the top ten US markets for Apple:

* San Francisco / Silicon Valley / Bay Area, CA – Residents are 49% more likely than the average American to be Apple users, no surprise with Apple’s headquarters just down the road in Cupertino.
* Boston, MA – Nearly 1/3 of adults in the Boston area have an iPod, iPhone, or Mac.
* San Diego, CA – 31.8% of the areas residents are Mac users
* New York, NY – 4.9 million Mac users
* Washington, DC – residents are 39% more likely to use a Mac, iPod, or Apple
* Chicago, IL – 2.1 million Apple users
* Denver, CO – 29% of the population are Apple users
* Monterey / Salinas, CA – 28% of the population own or use Apple products
* Santa Barbara / Santa Maria / San Luis Obispo, CA – this beachy region of southern California boasts a nearly 28% Apple user rate
* Las Vegas, NV – 27.9% of adults use an Apple product

Looking at the map is pretty interesting, you can really see the concentration of Apple users is highest around large cities, which is no surprise considering most of the Apple Stores are based in metropolitan areas. California is truly an Apple state, I don’t think I have ever visited a coffee shop or cafe in the Bay Area and not seen a sea of glowing Mac logos. The same is certainly true for many universities, where Mac’s dominate classrooms and campuses.

Apple continues to dominate the news cycle, this time with high scores in a consumer satisfaction survey. The survey of 23,400 online shoppers determined that Apple ranks number one among online electronic and computer retailers. Additional bragging rights for Apple include ranking number four overall for consumer satisfaction, behind only Netflix, Amazon and Avon. Impressive stuff!

I have to say that this doesn’t surprise me too much. I’ve had some really positive experiences with Apple lately, it’s one of the few stores I actually look forward to purchasing things from.

The Mac OS X Terminal can become slow to launch over time, but there’s an easy solution to speed it up again.

By deleting the Apple System Logs, you can shave the lag in opening and launching new Terminal windows/tabs dramatically, in my case from about a three second delay to instantaneous!

Here’s how to delete the log files and gain your Terminal app launch speed back:

From time to time iTunes can take a very long time to open, typically because it is looking for the music library.

If you find iTunes to be taking a long time to launch, you might try this simple fix seems to resolve the slow application launch issues:

* Launch iTunes

* Immediately hit and hold the “Option” / ALT key

* Select your iTunes Library, on your computer, often located in the user home folder or /Music/iTunes/

* Click OK

iTunes should now but be considerably faster when loading and quitting.

The interesting thing is that you’re loading the same music library as before, so the speedup must be related to a more recent cache being available.

This should work with iTunes on both Mac and Windows.

If you have any other tips to speed up iTunes, share with us in the comments!

You can run Mac OS X in Grayscale mode by adjusting the display settings in the Accessibility or Universal Access control panel. Likewise, you can stop a Mac from running in greyscale mode and get full color back by disabling the setting in the same system control panel.

This is an easy display settings adjustment to make, and it serves a variety of purposes.

The Spirit Jailbreak for iPad has been released, it’s an untethered Jailbreak for any of the current iPhone OS devices, so the iPad as well as iPhone and iPod touch are supported. It’s still in beta so it’s definitely a good idea to sync and backup all your data before trying this out. Many of the Cydia apps not designed for iPad may run a little strange, look poorly, or even ‘screw up your system’ as the Spirit developers say. It’s also worth noting that Spirit is not a carrier unlock, so don’t expect to jump around mobile providers.

Here are the requirements:

* iPad, iPhone, iPod touch on firmware 3.1.2, 3.1.3, or 3.2.
* iTunes 9 (including 9.1.1).
* An activated device: one not stuck on the Connect to iTunes or Emergency Call screen.
* A Mac or Windows PC

If you’re interested in Jailbreaks, check out the Spirit Jailbreak developer for more.

If you want to be absolutely sure your data is wiped clean with virtually no chance of recovery, by anyone, using any possible known recovery tools, look no further than Apple’s Disk Utility tool. The process is simple, and it can apply to any Mac drive, whether that’s an internal hard drive, external hard drive, and any connected drive of any format, meaning it does not need to just be a Mac drive to become securely formatted.

First a quick explanation of how secure format works: the drive is formatted and cleared of data as usual, but then the drive is rewritten with new randomly generated data, effectively overwriting any existing data on the drive and making it impossible to access or recover. It doesn’t stop there though, because that process is repeated multiple times, depending on which setting choice you select when securely formatting a drive. Let’s begin:
