How to Make an OS X Yosemite Boot Installer USB Drive
Now that OS X Yosemite is available, many users may wish to create a bootable installer drive from something like a USB flash thumb drive or another disk. This allows for several things, the ability to upgrade multiple Macs without having to re-download the installer, the ability to perform a clean install, and also the convenience of having a separate bootable reinstallation drive in the event you need it for serving a Mac.
Creating a Yosemite installation drive that is bootable is quite simple, but it’s a multiple step process. Before you begging, make sure you have the following basic requirements met:
Requirements
A USB Flash Drive that is 16GB or larger which you don’t mind formatting
The “Install OS X Yosemite.app” launcher in the /Applications/ directory of the Mac (downloaded from the App Store, but not installed)
Of course, we’re assuming the destination Mac(s) that are going to get Yosemite are compatible. Basically, if the Mac is capable of running OS X Mavericks, it is capable of running OS X Yosemite too.
How to Create a Bootable OS X Yosemite Installer Disk in 2 Steps
For the purposes of this walkthrough, we’re going to use a 16GB USB flash thumb drive, but you’re free to use whatever you want, and you could even use an external hard drive if you really wanted to. The convenience of a portable flash drive is undeniable so it’s preferred if you’re going to be updating multiple Macs. Let’s get started:
Step 1: Format the USB Drive to be Bootable
This is going to format the drive so that it will be a bootable installer, without doing this the drive may not be bootable. If you don’t want to erase the drive, find one you don’t mind formatting instead.
Connect the USB drive to the Mac and launch Disk Utility, then select the drive from the left side drive list
Click on the “Erase” tab and format the drive as “Mac OS Extended (Journaled)”, then choose “Erase” and confirm
Next go to the “Partition” tab and under ‘Partition Layout’ click on the pulldown menu, changing it from “Current” to “1 Partition”
Change the name to “Untitled” from ‘Untitled 1′ then click on the “Options” button
Choose “GUID Partition Table” as the partition scheme and choose “OK”
Click “Apply” and confirm the creation of the partition
Quit out of Disk Utility when finished
Now that the drive is ready, you can move on to making the actual installer.
Step 2: Making the OS X Yosemite Installer Drive
The next step will actually make the installer drive from the previously formatted USB disk. If you already have the OS X Yosemite installer application in the /Applications/ folder on the Mac, you can skip directly to
step 3: Download OS X Yosemite from the Mac App Store, it’s free (direct link) – DO NOT INSTALL IT YET
When the download completes and the “Install OS X Yosemite” app launches, quit out of it immediately
Launch Terminal app and enter the following command exactly, copy and paste works fine:
sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction
Enter the administrator password when requested (this is required to use the sudo command – the password will not show up and it looks as if you’re not entering anything, that is normal behavior for the command line), then hit the RETURN key to start making the installer
You’ll see a series of message like the following, let it finish until you see the “Done” message – this may take a while as multiple GB of data have to be transferred:
"Erasing Disk: 0%... 10%... 20%... 30%...100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done."
When finished and the terminal reads “Done”, exit out of Terminal, you’re ready to use the bootable installer drive
That’s all there is to it. Your freshly made OS X Yosemite install drive will be visible in the Mac Finder:
Now you just need to boot from the freshly made OS X Yosemite drive, do that by rebooting the Mac and holding down the OPTION key and selecting the “Install OS X Yosemite” drive upon boot.
If the drive does not boot, you almost certainly skipped the first step which was to partition the drive as GUID, or perhaps interfered with the syntax in the command. You can go through the process again to be sure.
This allows you to update any version of OS X from Snow Leopard, Lion, Mountain Lion, or Mavericks, directly to OS X Yosemite, with the installer that was just made. You can also perform a clean install (which we’ll separately address in a thorough walkthrough shortly), or update multiple Macs without having to download it from the App Store again. Be sure to always back up the target Mac before updating OS X, whether to OS X 10.10 or any other version, you can follow detailed instructions on how to prepare a Mac for OS X Yosemite here. Enjoy OS X Yosemite!
The aforementioned steps have been tested repeatedly and are confirmed to work flawlessly with the OS X Yosemite final release. If you have any issues, run through the steps again, or leave a comment with your specific error. If you know of an easier way, let us know in the comments too!

12 things you need to know about today's Apple event
Tim Cook gets ready to show off some new Apple products at the iPad Air 2 event. Photo: Apple
It’s been way too long, joked Apple, since any groundbreaking announcements like the Apple Watch and iPhone 6 Plus. While the product refreshes announced at today’s iPad-centric event aren’t as high on “wow” as the revelations during last month’s big show, these are solid updates to product lines that continue to make Apple great.
Here are the top 12 things you need to know from today’s Apple event.
iPhone 6 is the fastest selling iPhone, ever, says Tim Cook. Photo: Jim Merithew/Cult of Mac
The iPhone 6 was “the biggest iPhone launch ever”: Tim Cook called the iPhone 6 the “fastest-selling iPhone in history.” While he didn’t provide any numbers, he said the latest iPhones have racked up the most first-month orders ever and pointed out it will be in 32 countries by the end of the week — including China, where it will work on all three of the country’s networks for the first time ever. The iPhone 6 set a “new high-water mark for the most orders taken,” Cook said, “and I don’t mean by a little — by a lot. A whole lot!”
“This is Granny Smith, over.” Screengrab: Apple
Stephen Colbert is Apple’s new “chief of secrecy”: In the event’s best bit, Craig Federighi demonstrated the awesome power of Continuity by phoning Stephen Colbert, who he called Apple’s new head of secrecy. Colbert demanded that they talk in code. “Hello, Red Delicious,” Federighi said. “This is Granny Smith. Over.” It was a pretty hilarious way of putting a positive spin on all the recent security-related headlines about Apple, from the Fappening to Cupertino’s move to make data unavailable to police. In the end, Colbert got off the event’s best line: “Get back to work,” he told Federighi. “Because you know what I see when I look at my wrist? My wrist. Where’s the watch?” (P.S. Tim Cook’s code name? “Chairman Honeycrisp.”)
Eddy makes with the funny. Photo: Apple
Apple shows off its funny side: The humor today was thick, with Craig Federighi calling new “head secrecy emperor” Stephen Colbert from a Macintosh, introducing a third-party keyboard that lets you speak Klingon in your iMessages, and a skit where Eddy Cue gets rejected from a secret lab deep in Apple headquarters because he doesn’t know the ridiculous handshake. Are these too self indulgent? Perhaps, but it’s good to see a company that doesn’t take itself too seriously.
Yep, that’s right – you can grab this now. Photo: Apple
OS X Yosemite is now available, for free: We’ve been hearing about all the cool new features of the Macintosh operating system Yosemite for a while now, and Federighi went through a quick recap, talking through new notification, search and sharing from apps features, as well as Safari’s new tab view, named group chats, photo sharing, a new shelf for recent items in iTunes, and cool new text effects in Keynote, just to name a few things. He even got off a quick jab at Microsoft with the announcement of iCloud Drive on Windows.
All your photos, on all your devices. Slick. Photo: Apple
iOS 8.1 will be available on Monday: The latest, greatest mobile operating system sheds its growing pains with a release of a full dot-number version on Monday: iOS 8.1. This update will finalize all the cool things iOS 8 already does, polish up the Continuity and Handoff features to work better than ever with OS X Yosemite, and taking advantage of all the latest mobile tech, like faster Wi-Fi, Bluetooth low energy, AirDrop between Mac and iOS devices, and the ability to send Airplay streams to your TV without a Wi-Fi network.
Another 500 banks will work with Apple Pay. Photo: Apple
Taking over the world, one wallet and bank at a time: ApplePay & Touch ID comes to iPad, which, according to Phil Schiller, was the most requested feature for iPad. Touch ID will unlock the iPad Air 2 as well as work in specific apps, but you’ll only be able to use Apple Pay to make app and media purchases, though, since no mention was made of NFC in the new iPad Air 2. This is a good thing, because it’s bad enough that people use iPads to take pictures with — imagine waiting for the guy in front of you to pay for his latte with an iPad.
Tim Cook says, “Can you even see this?” before handing duties off to Phil Schiller. Photo: Apple
The iPad Air 2 is the thinnest iPad ever, and now comes in gold: The video Cook showed to unveil the latest iPad continued the “thin as a pencil” conceit from earlier iPad models, only this time, a laser beam shaved off the top bit of the pencil to demonstrate just how much thinner the new iPad Air 2 is. At 6.1mm thin, it’s the thinnest tablet out there: 18% thinner than iPad Air, which was 20% thinner than iPad 4. It’s till got the 10+ hour battery life to boast of, though, along with the A8X and M8 chips and brand new higher-end camera inside of it. Crazy thin, and you can get it in gold along with space gray and silver.
Best camera view screen ever, for sure. Photo: Apple
iPad Air 2 is now a great camera with the biggest view screen ever: A big deal was made of the new cameras on the thin new tablet as well. The rear facing camera is now an 8 megapixel iSight camera with 1.12-micron pixels and an aperture of 2.4. This camera, in conjunction with the A8X processor, will let you shoot 1080p home video along with capturing time lapse and slow motion videos for the first time on an iPad. The still camera will also let you capture photos with burst mode and grab stunningly high resolution panorama photos, too. The FaceTime camera gets an upgrade as well, with an all new sensor and aperture that lets in 81% more light. Now you can get more face detection, burst-mode for selfies (“All the kids do this,” promised Schiller), and single shot HDR and HDR video. Suddenly that woman taking photos at the Grand Canyon with her iPad doesn’t look so crazy.
You know you still want one. Photo: Apple
The iPad mini 3 is available: The new mini iPad was almost not worth mentioning, it seemed, as Schiller rushed through a quick beat about the new iPad mini 3 with Retina display. This new tiny powerhouse packs a 5 megapixel iSight camera, lets you shoot 1080p HD video recording, while still running a FaceTime HD camera on the front. It’s also gotten faster 802.11n with MIMO Wi-Fi and Touch ID, which we assume will work with Apple Pay the same as its larger brethren.
This makes your HDTV look blurry, right? Photo: Apple
iMac goes big and thin with industry-defying 5K Retina Display: The new iMac display is so ground-breaking that the Apple development team had to invent several new technologies like a timing controller, Oxide TFT, Organic passivation, and seriously power-efficient LEDs that use 30% less energy than previous ones. The new iMac is so densely packed with pixels– a stunning 14.7 million of them — that a 1080p HDTV (now with 67% less pixels than the iMac) looks paltry in comparison. All of this in a five millimeter thin casing that also includes a 3.5 GHz quad-core i5 processor, Thunderbolt 2 ports, and terabytes of storage with a new Fusion drive. That would be impressive at any price, but the new iMac starts at a super-friendly $2499.
When it comes to the Mac Mini, it *has* been far too long. Photo: Apple
Mac Mini gets a well-deserved upgrade: The underrated but highly useful Mac Mini gets a 4th generation today, with an Intel core processor, Intel Iris or HD Graphics 5000 chip, faster PCIe-based flash storage, now one but two Thundrbolt ports, faster 802.11 ac Wi-Fi and a $100 price drop to start at $499.
Every day we look forward to that day. Photo: Apple
Let there be WatchKit: Cook unveiled WatchKit, the developer framework that will roll out next month and let devs build useful apps for Apple’s upcoming wearable. “Apple Watch will be shipping early next year,” Cook said, “and every day I look forward to that day.” Like, every day.

Apple leaks new iPad details in iOS 8.1 user guide
This will probably be what the iPad Air 2 looks like.
Apple’s unveiling of its new iPad lineup is set to take place in less than 24 hours, but someone at Apple HQ just accidentally leaked some of the biggest details, including the names of Apple’s newest tablets.
Apple updated its iOS 8 user guide this morning with photos for the new ‘iPad Air 2’ and ‘iPad mini 3.’ The actual iBook contains no information about the new devices, but preview images for the iPad User Guide For iOS 8 on contains references to the addition of Touch ID and a Burst Mode for the Camera.
It appears that Apple will bring a numbering scheme back to iPad names, after ditching the process last year with the release of the iPad Air and iPad mini with Retina display.
Other new features on the iPad Air 2 are expected to include an A8X processor with 2GB of RAM, Apple Pay, improved camera, anti-reflection coating, and a slightly thinner design. Full details of the iPad Air 2 and iPad mini 3 will be revealed tomorrow at a press event on Apple’s campus in Cupertino at 10AM PT.

Google Nexus 6 is official with 6-inch QHD screen and S805
The premium display is backed up by a Qualcomm Snapdragon 805 chipset with a 2.65GHz quad-core Krait 450 CPU inside and 3GB of RAM. At the back, there's a 13MP f/2.0 camera with dual-LED flash. Internal storage is either 32GB or 64GB, but there's no microSD card slot.
At the front, there are two stereo speakers and a 2MP front-facing camera.
The battery is a 3,220mAh unit, which isn't user replaceable. However, it sports Turbo Charging, which allows you to get up to 6 hours of use from the Nexus 6 with only 15 minutes of charging. Google promises the phone can make it through 24 hours of usage without problems.
Pre-orders for the Motorola Nexus 6 start on October 29 with shipments scheduled to start some time in November. You can buy the 32GB, SIM-free version of the phone in Midnight Blue or Cloud White from the Google Play Store for $649.
Although not officially confirmed, in Europe the 32GB and 64GB models are expected to retail for €569 and €649, respectively.
Google won't stop selling the LG Nexus 5, for those worried they will be left without a more compact Nexus smartphone. Its pricing remains unchanged, $329 for the 16GB and $399 for the 64GB model. The Nexus 5 will also receive Android 5.0 Lollipop, so you won't be missing out on the latest Google has to offer.

Google unveils Android 5.0 Lolipop as an official name
Along with the announcement of the Nexus 6 and the Nexus 9 today, Google also announced that the next iteration of their mobile OS, which we so far knew under the codename Android L, will actually be called Android 5.0 Lolipop.
Android Lolipop was one of the top picks of the rumor mill anyway, but another not so distant possibility was also Lion, which seemed quite reasonable, bearing in mind it will follow right after KitKat.
Android 5.0 Lollipop will ship on the just announced Nexus 6 and Nexus 9, but it will also will also be available on Nexus 4, 5, 7, 10 and Google Play edition devices in the coming weeks.
Here you can find out more about Android 5.0 Lollipop.

How To Move or Rename Your Mac Home Folder
Your Mac’s home directory, or home folder, is represented by a little house in the Finder and is the default location for your documents, music, photos and other items on your computer. The name of the home folder is also your Mac account username, or “shortname” in UNIX parlance.
Since these items are related, the process for renaming the home folder and changing your username is similar to moving your home folder to another location such as a second hard drive. Here’s how it’s done.
Renaming Your User Account and Home Folder
The most common reason to rename a home directory and Mac account name is to correct a misspelling or change the name if a new user replaces an old one, such as an employee change in a business. The old or incorrect name has no ill effect on computer operations but can be psychologically annoying when things aren’t correct.
IMPORTANT: this is an advanced procedure that can result in loss of access to your data if done incorrectly. Make sure you read and feel comfortable with these instructions and how to use Terminal before making any changes. Also, BACK UP YOUR DATA before you begin. Time Machine is OK, a Hard Drive Clone is better. Make sure you can revert back to the old system if anything goes wrong.
For this example let’s start with a user named Bob Smith with the username bobsmith. We wish to change this for a new user, Jane Doe, with the username janedoe.
You need to use a second account on the Mac with administrator privileges to make the change. Log out of Bob Smith’s account (under the Apple menu), then log in to the separate admin account and open System Preferences. Choose the Users & Groups preference pane, click the lock to authenticate and enter your admin password.
Next, right-click (or control-click) on Bob Smith’s account in the left hand pane and choose Advanced Options…
This will bring up another window with a warning not to muck with things if you don’t know what you’re doing (always good advice).
Two things need to be changed in this dialog: the entries for Account name and the Home directory. For Account name simply replace bobsmith with janedoe.
Next, in the Home directory field change the existing entry as follows:
old: /Users/bobsmith
new: /Users/janedoe
new: /Users/janedoe
Double-check the entries for spelling and typos, then click OK. Your Mac will ask Are You Sure to confirm you indeed want to make this change, so this is the point of no return.
Finally, back in System Preferences, change the Full name you see in the account pane from Bob Smith to Jane Doe. The Full name is really just an alias to the shortname that’s easier for you and I to remember.
These actions change the Mac user ID record internally for the account. We now need to rename the actual home directory. This step is done with the Terminal application, located inside your Applications –> Utilities folder. Launch Terminal, then type the following at the command prompt:
sudo mv /Users/bobsmith /Users/janedoe
Make sure you type the old and new usernames correctly, then hit Return. You will be prompted to enter your admin account password. Type that in – the letters won’t show onscreen – then hit Return again. This command moves (mv) the entire folder from the old location to the new one, which in this case is effectively just a rename operation. Since the move is “in-place” on the same hard drive the process should only take a few seconds, then a new blank command line will appear.
When finished quit Terminal and System Preferences, then reboot your Mac. Upon restart the account name and home directory will both have been renamed to janedoe.
Moving Your Home Folder to a Different Drive
Sometimes you’re not looking to rename an account but actually move the home directory to a separate drive or partition. This is a common setup for servers and can also be used on any system where you want to keep things separate, such as having the Operating System and Applications on a Solid State Drive and the user data on a larger (but slower) hard disk drive.
The process is similar to renaming a home folder, but in this case we’re keeping the same username and changing the location. As above, log out of the account to be changed and log in to a second admin account. Open System Preferences –> Users & Groups, right-click on the account to be changed and choose Advanced Options…
In the Advanced dialog box leave the account name as is (bobsmith) but change the location of the Home directory. Let’s say we want to move the home directory to a hard drive named Employees. Using the Finder create a folder named Users on the Employees drive. Then, change the Home directory entry as follows:
old: /Users/bobsmith
new: /Volumes/Employees/Users/bobsmith
Correct entry and spelling of this data is critical. Verify there are no typos, then click OK to save these changes.
Terminal is your next step, and this time the files will actually be moved between the two hard drives. Open Terminal and at the command prompt type:
sudo mv /Users/bobsmith /Volumes/Employees/Users/bobsmith
Enter your admin account password when prompted, then hit Return. This operation may take some time depending on how much data has to be moved, do not interrupt the process or use the Mac for other tasks while this is happening. When the copy is complete you will see a new command line prompt appear in the Terminal window.
Verify that the folder has actually moved to the new drive, then restart the Mac and you should be good to go. Note that the second drive should be a Mac-formatted volume, and if it’s not an internal disk it will need to be connected and powered up whenever you’re using the Mac for the home directory to be accessible.
Changing the Account Name on Pre-Leopard Systems
The above steps are common procedures for UNIX-based systems but are made simpler by Apple’s inclusion of the Advanced Options dialog for changing account names. The process is a bit more complex for pre-Leopard Macs, but if you’re running Tiger (OS X 10.4.x) or Panther (10.3.x) on your Mac there’s a handy utility available which can automate the name changing for you.
ChangeShortName is a freeware utility by Dan Frakes which automates changing the username via a series of pre-configured terminal scripts. As above, log out of the user account to be changed and make changes from a second admin account on the Mac. ChangeShortName will prompt for the old and new names, make the necessary changes, then prompt you to reboot your machine.
Note that this utility will not work with OS X 10.5.x or higher. If your Mac is running something even older than Panther, frankly it’s time to upgrade to something newer! Very little current software runs under these older OS versions, time and energy is better spent migrating to a newer system.

How to change Joomla Admin Folder Name or Path ?
Many times people ask me, how you secure your joomla
website,specially how to protect your admin side of website.So I think
about to change the admin url.
By default, every joomla programmer know the default url of admin directory i.e. http://sitename.com/administrator/ .
So I want to hide or just don’t want to give direct access to that url, after googling, found that changing the folder name ‘administrator’ to ‘myadmin” & change the ,
define( ‘JPATH_ADMINISTRATOR’, JPATH_ROOT.DS.’administrator’ ); to
So finally I found another trick which work for me, is as below.
1. Create a new directory in your root directory (eg. “myadmin”)
2. Create an index.php file in your “myadmin” directory..
<?php
$admin_cookie_code=”999999999″;
setcookie(“JoomlaAdminSession”,$admin_cookie_code,0,”/”);
header(“Location: ../administrator/index.php”);
?>

in the ‘includes->defines.php’
& ’administrator->includes->defines.php’ doesn create some
problem in thired party component.So finally I found another trick which work for me, is as below.

3. Add this to the beginning of index.php in real administrator folder
#administrator/index.php (modify , **do not replace**)
if ($_COOKIE['JoomlaAdminSession'] != “999999999″)
{
header(“Location: ../index.php”);
}
This works for me, I hope it will help others also.
