I. Mac OS X:
1. Install Adobe Master Collection.
2. Use the X-FORCE keygen or Keymaker.Only-CORE to generate your serial on a windows machine or use  one of the serials listed below.
3. When installation is finished run disable_activation_osx as root. If you dont  know how to do that open a terminal window and then issue sudo -s, a root shell  will open, then simply do "sh disable_activation_osx"  w/o the "" or  ./disable_activation_osx ( make it executable chmod 755 disable_activation_osx  you do that from the folder where disable_activation_osx is (just copy it  anywhere on your hdd).
4. Done.

NB : if you have problems with authentification when you start application, check the file /etc/hosts and make sure you have a line like this:
127.0.0.1 activate.adobe.com
127.0.0.1 *.* ... (See below)
If you don't add it manually open a terminal and use your favourite editor.
You must do that as root, example (after opening a terminal window) :
sudo pico /etc/hosts then at request put your root password.

- If you've previously entered a serial, load any CS4 app, go to the Help menu and Deactivate. Quit any open CS4 apps
Open Terminal (found in Applications/Utilities/). In the terminal window, paste in:
sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts
Return / Enter admin pass / Return
Add lines to your hosts:
127.0.0.1 wwis-dubc1-vip60.adobe.com
127.0.0.1 activate-sjc0.adobe.com
127.0.0.1 activate.wip3.adobe.com
