How to Crack Mac OS

Reset the Password in Single User Mode

SEXPAND

If you don't have an installer CD handy, you just need to do a bit of fancy command-line footwork to achieve the same end as the CD method. Boot up the computer, holding Command+S as you hear the startup chime. The Mac will boot into single user mode, giving you a command prompt after loading everything up. If the Mac is running Snow Leopard or below, type the following commands, hitting Enter after each one and waiting for the prompt to come up again before running the next one:

/sbin/fsck -fy
 /sbin/mount -uw /
 launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
 dscl . -passwd /Users/whitsongordon lifehacker

If the Mac is running Lion or above, you'll instead want to use the following commands:

/sbin/fsck -fy
 /sbin/mount -uw /
 launchctl load /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist
 dscl . -passwd /Users/whitsongordon lifehacker

Replace whitsongordon with the user whose account you want to access andlifehacker with the new password you want to assign to that user. If you get an error message about com.apple.DirectoryServicesLocal.plist on a Lion or Mountain Lion machine, just ignore it—the password reset should still work.

If you don't know the user's username, it should be pretty easy to run ls /Users at any time during single user mode to list all the home folders on the Mac, which usually correspond to the usernames available on the Mac. Note that the user's password is different than the root password. If you want access to the more secured parts of their machine—like their password keychain—you can change their root password by running this commandafter loadingopendirectoryd.plist:

passwd root

Once finished, you should have access to most of their system, including their saved passwords for other apps.

How to Crack Linux Password?

How to crack the Linux password?

This method can work with most of the Linux Distribution, but not with all.

As soon you start your Linux System, you will get a prompt for selecting the operating system shown below.(I am using Redhat Enterprise Linux Server).

Press space bar immediately as soon as you get the above screen (The screen remains open only 3 seconds).

Press “e” from this screen to edit the command before booting. You will get another window looks like below

Select the middle option which has got a word “quiet”(This word will be appearing any part of the line”) and press “e” again. This will bring another window looks below

Remove the word “quiet” and type “single” in the  place of “quiet” and press “Enter”. This will bring the previous window and press “b” to boot the operating system.

After booting the operating system it will bring console prompt(Command prompt) of Linux OS. This prompt is the root console prompt and  type “passwd” to change the  password of “root” user. Reboot the system and use the password which you have set now.

Enjoy!!! You have cracked the Linux system password using this method

Installing the Eclipse Plugin for Andriod Application

Installing the Eclipse Plugin

Android offers a custom plugin for the Eclipse IDE, called Android Development Tools (ADT). This plugin provides a powerful, integrated environment in which to develop Android apps. It extends the capabilities of Eclipse to let you quickly set up new Android projects, build an app UI, debug your app, and export signed (or unsigned) app packages (APKs) for distribution.

Note: You should install the ADT plugin only if you already have an Eclipse installation that you want to continue using. If you do not have Eclipse installed, you should instead install the complete Android SDK, which includes the latest IDE for Android developers.

Your existing Eclipse installation must meet these requirements:

• Eclipse 3.7.2 (Indigo) or greater
  Note: Eclipse 3.6 (Helios) is no longer supported with the latest version of ADT.
• Eclipse JDT plugin (included in most Eclipse IDE packages)
• JDK 6 (JRE alone is not sufficient)
• Not compatible with GNU Compiler for Java (gcj)

Download the ADT Plugin

---

To add the ADT plugin to Eclipse:

1. Start Eclipse, then select Help > Install New Software.
2. Click Add, in the top-right corner.
3. In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location:

   https://dl-ssl.google.com/android/eclipse/

   Note: The Android Developer Tools update site requires a secure connection. Make sure the update site URL you enter starts with HTTPS.
4. Click OK.
5. In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
6. In the next window, you'll see a list of the tools to be downloaded. Click Next.
7. Read and accept the license agreements, then click Finish.
   If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
8. When the installation completes, restart Eclipse.

Configure the ADT Plugin

---

Once Eclipse restarts, you must specify the location of your Android SDK directory:

1. In the "Welcome to Android Development" window that appears, select Use existing SDKs.
2. Browse and select the location of the Android SDK directory you recently downloaded and unpacked.
3. Click Next.

Your Eclipse IDE is now set up to develop Android apps, but you need to add the latest SDK platform tools and an Android platform to your environment. To get these packages for your SDK, continue to Adding Platforms and Packages.

Troubleshooting ADT Installation

---

If you are having trouble downloading the ADT plugin after following the steps above and you are behind a firewall (such as a corporate firewall), make sure that you have properly configured your proxy settings in Eclipse. In Eclipse, you can configure proxy information from the main Eclipse menu in Window (on Mac OS X, Eclipse) > Preferences > General >Network Connections.

If you are still unable to use Eclipse to download the ADT plugin as a remote update site, you can download the ADT zip file to your local machine and manually install it:

1. Download the ADT Plugin zip file (do not unpack it):

   Package	Size	MD5 Checksum
   ADT-23.0.3.zip	103321934 bytes	ab2f5e2fbbdddeeb7dfd02cd4046538a

2. Start Eclipse, then select Help > Install New Software.
3. Click Add, in the top-right corner.
4. In the Add Repository dialog, click Archive.
5. Select the downloaded ADT-23.0.3.zip file and click OK.
6. Enter "ADT Plugin" for the name and click OK.
7. In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
8. In the next window, you'll see a list of the tools to be downloaded. Click Next.
9. Read and accept the license agreements, then click Finish.
   If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
10. When the installation completes, restart Eclipse.

To update your plugin once you've installed using the zip file, you will have to follow these steps again instead of the default update instructions.

Other install errors

Note that there are features of ADT that require some optional Eclipse packages (for example, WST). If you encounter an error when installing ADT, your Eclipse installion might not include these packages. For information about how to quickly add the necessary packages to your Eclipse installation, see the troubleshooting topic ADT Installation Error: "requires plug-in org.eclipse.wst.sse.ui".

For Linux users

If you encounter this error when installing the ADT Plugin for Eclipse:

An error occurred during provisioning.
Cannot connect to keystore.
JKS

...then your development machine lacks a suitable Java VM. Installing Sun Java 6 will resolve this issue and you can then reinstall the ADT Plugin.

Installing Android Studio

Android Studio provides everything you need to start developing apps for Android, including the Android Studio IDE and the Android SDK tools.

If you didn't download Android Studio, go download Android Studio now, or switch to the stand-alone SDK Tools installinstructions.

Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type javac -version. If the JDK is not available or the version is lower than 6, go download JDK.

[ Show instructions for all platforms ]

To set up Android Studio on Windows:

1. Launch the .exe file you just downloaded.
2. Follow the setup wizard to install Android Studio and any necessary SDK tools.
   On some Windows systems, the launcher script does not find where Java is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.
   Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for exampleC:\Program Files\Java\jdk1.7.0_21.

The individual tools and other SDK packages are saved outside the Android Studio application directory. If you need to access the tools directly, use a terminal to navigate to the location where they are installed. For example:

\Users\<user>\sdk\

Android Studio is now ready and loaded with the Android developer tools, but there are still a couple packages you should add to make your Android SDK complete.
