Sync iPhone or iPod on multiple computers - iTunes PC/Mac

You've probably noticed that it is impossible to sync your iPhone on two or more computer. It's a really annoying limitation! Here is how you can get rid of that :

1. First, backup the "iTunes Music Library.xml" and "iTunes Music Library" (Tunes Music Library.itl for PC user). They are located in Music / iTunes Folder

2. On the machine your iPhone is currently synched with, open "iTunes Music Library.xml" with a text editor (TextEdit on mac, Notepad on Windows).

3. Find the entry between the tags, after "Library Persistent ID" . It should be an alphanumeric string containing 16 characters/digits. Copy this entry in a text document or write it on paper. ex : 8B6C633F7DACB74B

4. Now go to the computer you want to synch with and make sure iTunes is not running.

5. You will need to change the Persistent ID in two file. An XML File and a Binary File.

6. First, open the XML File "iTunes Music Library.xml" and find the entry between the tags, after "Library Persistent ID". Copy the string that is here (you will need it later) then replace it with the string you copied at step 3(the one from the computer your iPhone is synched with). MAKE SURE YOU DON'T CHANGE ANYTHING ELSE.

7. Save the XML File and close it.

8. Now open the binary file ("iTunes Music Library" on Mac and "Tunes Music Library.itl" on PC) in an Hex Editor (Windows : HxD , Mac : HexEdit)

9. With the command "Find and Replace" look for the ID you copy in step 6 and replace it with the ID in step 3. Make sure you search type is Hezadecimal not ASCII. Replace all occurences.

10. Save the file and close it.

11. That's it!

12. Launch iTunes on the second machine you wish to sync with and plug in your iPhone. When you select "Manually manage music and videos" you will no longer be prompted to delete music, nor will the files on your iPhone be grayed out.

Crack root password on Mac OS X. Change the password or find it.

Here is a technique to change or get the root password on an apple computer running Mac OS X.

1- Restart your computer in single user mode by holding the CMD+S key at the booting.

2- Type : /sbin/mount -wu / to mount the hard drive

3- Type : /sbin/SystemStarter to start the network services

4- Now you have to choice :

a) Change root password : passwd root

b) Get the root by password :
b.1) Type : nidump passwd
b.2) Now write the line looking like root:rQkFQ37SYveHw:0:0::0:0:System Administrator:/var/root:/bin/tcsh in a text file and crack it with a cracking program like John the Ripper.

Get the password of any user in Mac OS X

This is how you can get the password of any user in Mac OS X. It is a technique called Swap File Hack.

You will first need to login as root. First login with an administrator account. If you don't have access to an administrator account please read «Crack Mac OS X Administrator password - create new admin account». Once you're logged in as an administrator, go to Applications » Utilities » NetInfo Manager and open it. In the top menu, go to Security and enable root user. Choose a master password. Than, logout, and log back with the new "root" account, with your master password.

Once your logged in as root, go to System Preferences » Personal » Security. Un-check «Use secure virtual memory».

Next, change the amount of RAM memory in the computer.Changing the amount of memory will create something called swap files, that include the passwords.

After the memory change, log back with the root account, open up Terminal, and enter this:


sudo strings -8 /var/vm/swapfile0 |grep -A 4 -i [longname]


Replace «[longname]» with the long name of the account you want the password. Look around for the word "password", and you should find what you need!

Crack Mac Os X Open Firmware Password - Enable boot options & keyboard shortcuts

If the booting options(like Single User Mode) and keyboard shortcuts of your computer are disabled or locked by a password, this is probably caused by the firmware protection of Mac Os X. One good way to know that this is the firmware protection, is to hold the ALT key while rebooting. If you see a box asking for a password, this is the openfirmware protection. This is usefull if your system only boot on Windows XP and you want to change booting disk (with ALT key). Here is the solution to reset that password.

To crack the firmware protection:
Change the amount of RAM memory in your computer (remove or add DIMMs)
then you reboot the computer while holding CMD+OPT+P+R. Hold the keys until it restart and you hear the apple song. Release them then hold it again. Wait for restart and release then hold it again (basically you need to do it 3 times).
