Steps :
1. Go to "http://www.blogger.com/www.aspyr.com/"
2. Then at the top of the page, there would be a section called "Patches".
3. Click on this, and on the right of the page there is a list of Games that have patches.
4. Click on Call of Duty 4.
5. Go to the latest patch which is the 1.7 patch and go to the "Digital Verison" download not the "Boxed". (Boxed is for the retailed and bought version)
6. Download it.
7. Open it up. (If it is a .zip file, open it to the end then click on Call of Duty 4 1.7.1 Installer)
8. Install the game to the Macintosh HD
9. Then you have it at 1.7 patched version now. (This includes new maps, such as (Chinatown, Creek, Killhouse and Broadcast).
11. When you reach the sites, find an IP address of your choice and copy it.
12. Then open up the console by pressing the tilde key (~) and type "connect xxx.xx.xx.xxx:xxxxx". (These x's represent the IP address numbers). Then paste it spaced after "connect". [Hint: "~"/ tilde key is usually found below the "esc" key]
13. If you press (~) and the console won't bring up, it is that you have not enabled it. Go to (Options --> Game Options --> Console --> Enable).
13. If you fail to reach any of these websites, type up "Cracked Servers COD4" on google.
ENJOY! :)
Hope it Works
