Mac OS X : suddenly disappear Chinese Input Methods

This is the method to solve the problem

(1) Create a newuser and see if the Input Method can be selected in International Preference

(2) If the newuser can access the Input Method, then it is preference setting problem

(3) login the newuser and copy the following files from folder ~/Library/Preferences to in a common folder
com.apple.systempreferences.plist
TCIMHaninUserDictionary
com.apple.inputmethod.TCIM.plist

(4) login the olduser and copy the above files back to ~/Library/Preferences

(5) Reboot Mac

How to decrypt iPhone IPA file

Decrypted IPA
Please take note that you don't need this method to decrypt the IPA file, if you already have the decrypted one downloaded from the net. This method applies to the app that you have directly purchased from App Store and want to decrypt it in order to be useful for others.

One of the decrypt methods is to use a jailbreak iPhone and run the script (source from pr0x.org Forum) below in iPhone to create the decrypted ipa.

To use this method you must have installed the app from App Store in jailbreak iPhone plus the following packages from Cydia
com.ericasadun.utilities gdb gawk zip ldid odcctools

Use the following commands in iPhone to install, if you don't like to use Cydia.
apt-get install com.ericasadun.utilities gdb gawk zip ldid odcctools

To find out the app names that your iPhone have installed, run this command in iPhone
find /var/mobile/Applications/ -iname *.app

and use this command to generated the decrypted ipa e.g.
./DCrypt.sh "Monkey Ball"

DCrypt.sh Select all

If you only want to manually get the decrypted binary for reverse engineering. Suppose the Application Executable is called AppExec and installed in /var/mobile/Applications. This is the script and using the gdb to dump the decrypted binary

Let's use a free app AdHoc Helper (by Erica Sadun) as example


otool -l `find /var/mobile/Applications -iname AdHoc` | grep cryptsize

output-> cryptsize 8192

# get the cryptsize say 8192

gdb `find /var/mobile/Applications -iname AdHoc`

(gdb) b *0x2000
Breakpoint 1 at 0x2000
(gdb) r
(gdb) x/20i 0x2000
(gdb) dump binary memory /var/root/dump.bin 0x2000 (0x2000+8192)
(gdb) kill
Kill the program being debugged? (y or n) y
(gdb) quit

cd /var/root/
cp `find /var/mobile/Applications -iname AdHoc` .
dd seek=4096 bs=1 conv=notrunc if=dump.bin of=AdHoc


How to install iLife 09 on Mac OS X 10.5.5

iLife 09 requires Mac OS X 10.5.6

If you want to install it in 10.5.5, you need to change the SystemVersion.plist

sudo vi /System/Library/CoreServices/SystemVersion.plist

and change this

<key>ProductVersion</key>
<string>10.5.5</string>


to

<key>ProductVersion</key>
<string>10.5.6</string>


You cannot change the SystemVersion.plist back after installation, as iPhoto 09 and iMovie 09 will check this when launch.

If you want iPhoto 09 to skip the check*, you need to use a hex editor
open and change this file
/Applications/iPhoto.app/Contents/MacOS/iPhoto
then find (do multiple finds) and replace 10.5.6 to 10.5.5 and save it

*this trick does not work on iMovie 09

How to install iWork 09 on Mac OS X 10.5.5

iWork 09 requires Mac OS X 10.5.6, but I want to install it in my 10.5.5 machine and don't want to upgrade Mac OS

Here are the steps

(1) download iWork 09 Trial from Apple


(2) Use Disk Utility to convert the iWork09Trial.dmg into a read-write image file say iWork09.dmg

(3) Mount the newly created read-write image iWork09.dmg

(4) Use Terminal to enter the command

shell script: Select all


cd /Volumes/iWork\ \'09\ Trial\ Install\ DVD/Packages/iWork09Trial.mpkg/Contents/

vi iWorkTrial.dist



and change this

if (-1 == system.compareVersions(system.version.ProductVersion, '10.5.6'))


to

if (-1 == system.compareVersions(system.version.ProductVersion, '10.5.5'))


(5) Start the Installation from the mounted image

(6) After Installation completed

(7) Use Terminal to enter the command

shell script: Select all


sudo defaults write /Library/Preferences/com.apple.iWork09.Installer InstallMode -string 'Retail'



(8) Then start any iWork 09 application, it will ask you to register, click register later

(9) It will ask you three times after you close and then open any iWork 09 app, then the option of "never register" will appear. Proceed to click never register.

(10) In case you did not do step (7), it will ask you for the serial number, enter this
Y93U-HMME-3YRG-MOFO-MOFO-5S2

Enjoy.
