iTunes carrier testing mode allows you to manually load signed .ipcc carrier files onto an iPhone or cellular iPad, these .ipcc files contain various carrier settings pertaining to voice mail, MMS and SMS, Personal Hotspot, APN settings, and other network-specific preferences. If you’ve used an iPhone on T-Mobile or even as a prepaid phone you may have experience with these files, but other than making network configuration easy they can also be used to forcibly enable features that are otherwise disabled by default, like Personal Hotspot on certain international iPad 4G devices. We’ll cover how to enable carrier testing mode, how to find ipcc files, and then how to use those IPCC files with either an iPhone or iPad with a cellular connection.

Enabling Carrier Testing Mode in iTunes

The process to enable carrier testing is a bit different for Mac OS X and Windows.

Mac OS X:

1. Quit out of iTunes
2. Launch Terminal from /Applications/Utilities/
3. Enter the following command at the prompt and then hit return:

defaults write com.apple.iTunes carrier-testing -bool YES

4. Relaunch iTunes

Windows:
If you happen to use an iOS device with Windows, iTunes carrier testing mode is enabled by launching iTunes as an exe with a flag attached to it:

%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt carrier-testing 1

Finding & Downloading .ipcc Files
All signed ipcc carrier settings files are stored in an xml file on apple.com, you can access that gigantic list here:

http://iphonediags.apple.com/version.xml

Find the carrier file you want to use and then copy the URL and paste it into your browser address bar to download it directly from Apple. Save that file somewhere that it is easy to find for using with iTunes.

Loading .ipcc Files onto an iPad or iPhone with iTunes

Now that carrier mode is enabled, you can load carrier files onto the iOS device. In either OS X or Windows:

1. Connect the iOS device to the computer
2. Launch iTunes and hold the Option key while clicking on “Check for Update” to load an .ipcc file
3. Select the .ipcc file to sync the .ipcc to the iOS device
4. Disconnect the iOS device and reboot it for changes to take effect

We were sent this tip as a method to forcibly enable the Personal Hotspot wi-fi router on Australian 3rd gen iPads, which apparently ship with the feature disabled by default. The solution to that problem is apparently just a matter of loading an ipcc file and rebooting the iPad. Thanks to Jeremy for the tip info!

If you find yourself adjusting things in System Preferences often enough, it’s helpful to create a universal keyboard shortcut to quickly launch into the control panels on the Mac.

Here is how to do that in Mac OS X:

For those of us in the northern hemisphere, summer is fast approaching and that can often mean extreme heat which pushes the temperature limits beyond what any computer is intended to operate in. In fact, Apple specifies ambient operating temperatures for most Macs as between 50° and 95° fahrenheit, this means that anything above 95° goes beyond the conditions the Mac was specified to function within.

Most Apple fans own several iProducts since it’s so easy to go from a Mac to an iPad to an iPhone, but Fabiano F. has a setup that goes beyond Apple gear and branches into other mobile platforms, including Palm, Android, and even a Kindle. Hardware shown from left to right is:

• iPhone 4S
• Palm Treo 650
• iMac 21″ with an Apple wireless keyboard and Magic Mouse
• Galaxy Tab 2
• iPad 2
• Kindle
• MacBook Air 11″

This is a great Mac setup on a clean glass desk which matches Apple gear so well. It may be an unpopular opinion, but the home screen of the Android tablet is kind of nice with the weather widgets and other customizations, test Android 4 yourself within the constraints of a virtual machine and you’ll see some of the obvious pros and cons to a widgetized home screen. Maybe widgets will come to iOS some day, beyond Notification Center?

Check out past Mac setups, and send in your own setup shots to osxdailycom@gmail.com, include a list of hardware and a brief description of what you use it for.

If you have a group of pictures which are orientated incorrectly that you need rotated either clockwise or counterclockwise, you can do that in Mac OS X without any third party apps. Bulk rotation of images can be accomplished quickly with the help of the bundled Preview app, we’ll show you how to use the app for this purpose with almost any group of compatible image files in a variety of formats, be it a group of JPG’s, GIF, PNG, TIFF, or anything else that can be opened in the Preview application.

Everyone has run into a webpage where the font size is unbearably small on an iOS device, typically a reverse pinch gesture will make the text legible but on some pages that have a fixed width you then have to scroll sideways in addition to up and down. You can sort of get around that font size limitation by using the Reader feature on an iPhone or iPad, but that’s not ideal for every website either. This is precisely what two handy bookmarklets aim to resolve, by creating two fontsize increase and decrease buttons that can be accessed directly in Safari.

This addition is so useful that the concept should probably be included in future versions of Safari for iOS but only time will tell if that happens. In the meantime here’s what you need to do to get this working.

Repeat this process separately for both the increase and decrease functions:

1. Open Safari on iPad or iPhone and create a bookmark for any page
2. Tap the Bookmarks button at the top of the screen and choose “Edit”
3. Edit the newly created bookmark, naming it either a minus (-) or plus (+) symbol and replace the URL by pasting in the appropriate javascript code shown below, depending on the desired function
4. Save the bookmark change and load a new web page, tap on the + or – buttons to test font size changes live. Refreshing the page restores the font size to it’s default.

Decrease Font Size (-)

1

javascript:var p=document.getElementsByTagName('*');for(i=0;i<p.length;i++){if(p[i].style.fontSize){var s=parseInt(p[i].style.fontSize.replace("px",""));}else{var s=12;}s-=2;p[i].style.fontSize=s+"px"}

Increase Font Size (+)

1

javascript:var p=document.getElementsByTagName('*');for(i=0;i<p.length;i++){if(p[i].style.fontSize){var s=parseInt(p[i].style.fontSize.replace("px",""));}else{var s=12;}s+=2;p[i].style.fontSize=s+"px"}

These bookmarklet tweaks work by editing a bookmark URL and replacing it with a javascript that changes on page behavior, similar custom bookmarklets have allowed us to View Page Source in iOS Safari and even use Firebug on iOS.

This very handy solution comes from Marcos.Kirsch.com.mx, who recommends placing them in the Safari bookmarks bar for easy access.

Unhappy with iOS 5.1 and tethered booting a jailbroken device? A new version of the redsn0w jailbreak utility allows users to downgrade their iOS hardware from iOS 5.1 to iOS 5.0.1, allowing for a return to an untethered jailbreak with the previous iOS version. Perhaps most significantly, the redsnow assisted downgrade works on all A5-equipped hardware, including the iPad 3, iPad 2, and iPhone 4S. There is a caveat though, downgrading is only possible for iOS devices which have SHSH blobs saved with Cydia or TinyUmbrella, an activity that must have been performed on a jailbroken device at the time it was running 5.0.1.

To use the new downgrade functionality in redsn0w, download the latest version, launch the app, and click on “Extras” followed by “Even More” and then “Restore”. You will need the iOS 5.0.1 IPSW file to complete the task.

Download Redsn0w 0.9.11b1

• Get it for Mac
• Get it for Windows

For those without SHSH blobs saved, there remains a tethered jailbreak available for iOS 5.1.1 and an untethered variation for all devices is currently in the works with a release expected sometime over the next few weeks.

You can find more information about this specific release on the Dev Team blog.

If you’ve ever started to accidentally download an app of something on an iPhone, iPad, or iPod, or you just decide you want to stop an app download for some other reason, you can pause and stop downloads onto iOS devices that come from the App Store.

This tutorial will detail how to stop a download from the App Store in iOS. Additionally, we’ll show you how to pause a download from the App Store and how to resume that download to iOS again.

The stop trick works to cancel the download of any app in any version of iOS, it works the same on all iPhone, iPad, and iPod touch devices too.

Ever since Mac OS X 10.7, the Mac has included the same elastic over-scrolling that exists in the iOS world. Frequently called “rubberband scrolling”, it kicks in as an overscrolling effect that runs out of the scrollable region revealing the linen background before snapping back into the scrollable region. Scroll up quickly with or without inertia in virtually any window of OS X to see the effect in action. Rubberbanding makes for good eye candy and makes the Mac feel familiar to those coming from the iOS world, but some users are annoyed with it and will appreciate the ability to disable the scroll elasticity completely.

If you want to ditch the elastic rubber band stylized scrolling, you can do so through a defaults string. This works in OS X Mavericks, Mountain Lion, too, and can be quickly reversed if necessary.

Mac OS X 10.7.4 Update has been released by Apple, the update includes bug fixes and security updates and is recommended for all OS X Lion users to install. Two of the most significant changes are a fix to a restoring windows bug and a patch for a potential security issue with FileVault passwords, though there are a handful of other changes and fixes that are listed below in the changelog. An update to Safari is also bundled within the software update.

OS X Lion users can download the OS X 10.7.4 update directly via Software Update from the  Apple menu, the update weighs in around 730MB. Direct download links are below, though most users should upgrade through Software Update to keep things simple.

OS X 10.7.4 Direct Download Links

These are direct download links from Apple servers, each file is a DMG.

• OS X Lion 10.7.4 Client – 693mb
• OS X Lion 10.7.4 Client Combo – 1.4GB
• OS X Lion 10.7.4 Server Combo – 1.5GB

All Mac users should perform a backup before installing system software updates, initiating a manual backup with Time Machine is just a matter of right-clicking a drive.

If you have several iPhones, iPads, or iPods that need updating to the latest version of iOS, you can use a nice trick to save some bandwidth and download a single iOS update file to apply to multiple devices from either Mac OS X or Windows. This is a perfect solution for a family that has multiple iPhones or iPads that need updating, particularly when you don’t want to download the same firmware multiple times.

Mac OS X Snow Leopard can be upgraded directly to OS X Mountain Lion, assuming the final release maintains the same capacity as the currently available developer previews. To perform the direct upgrade as it stands today, users will need to have created an OS X Mountain Lion USB installer from which to boot off of and upgrade with, though there is a possibility that a Snow Leopard Mac will also have access to Mountain Lion directly from the Mac App Store.

We have received many questions about this in our inboxes and comments and figure with the OS X Mountain Lion release date set for summer it’s a good time to answer it based on currently available information. It’s important to note this upgrade path is based off of the current developer previews of Mountain Lion and upgrade eligibility could change before the public release, it’s also possible that Apple won’t officially support upgrading from Mac OS X 10.6 to 10.8 and this could remain an unofficial and unsupported feature.

A fair amount of OS X Snow Leopard users have held off on upgrading to OS X Lion, but with the release of Mountain Lion around the corner it’s quite likely a lot of OS X 10.6.8 holdouts will jump directly to OS X 10.8 if it is possible. Mountain Lion does have stricter system requirements than it’s predecessor, however, and some owners of older Mac hardware could wind up with Lion being the last supported version of OS X on their machines.

We will update with additional information on the various Mac upgrade paths to OS X Mountain Lion as further details become available.

By using Mac OS X Smart Folders, anyone can quickly access all files they were working on yesterday without caring about where they were stored or what folders they reside in. There are two ways to set this up, the first will utilize a quick modification to “All My Files” and the second will be more inclusive by creating a custom Smart Folder.

By appending the say command to the end of another command, Mac OS X will vocally announce when the initial task has finished running successfully. For example, to have OS X announce that a particular script has finished running the command could be:

python backup.py && say "jobs done"

The important part is the “&& say” portion, which can also be customized with other voices from Mac OS X’s text to speech options by using the -v flag followed by a voice name, like so:

dscacheutil -flushcache && say -v Alex your cache has been cleared sir

This is perfect for running scripts, making svn/git commits, compiling code, and other tasks that can take an indeterminate amount of time to complete and where it’s easy to become distracted by facebook^H^H^H^H^H^H^H^H other work.

This great tip was posted by @niels on Twitter, follow @osxdaily there too to get our latest posts and updates.

For the power users out there who prefer to leave their hands on the keyboard as much as possible, you’ll be pleased to know that the Dock in Mac OS X can be used exclusively from the keyboard with full functionality.

With just the right keys pressed and keystroke combinations, you can navigate around Dock items and apps, access the right-click menu, launch apps, force quit apps, hide others, and more.

We’re going to highlight some of the most useful keyboard shortcuts for using the Mac Dock.

Rich text format doesn’t always translate well to the web and it often gets garbled through emails sent across platforms. The simplest solution is to convert the RTF to plain text and then either transfer the resulting txt file or paste the content it into an email or otherwise.

Here is how you can do that quickly and freely in Mac OS X using none other than the built-in TextEdit app:
