To my knowledge the highest version for MOH:AA is 1.11. you can download it at [url:98d0c]http://www.eagames.com/official/moh_alliedassault/download/demo.jsp[/url:98d0c] its towards the middle of the page.

From there you put your .pk3 files (maps mods skins) in the folder Program Files>EA Games>MOHAA>main located on your hard drive. remember you have to have WinZip inorder to extract the downloaded PK3's
Im not exactly a MAC expert but in general the "main" folder under the MOHAA directory is where you want to put you pk3's, and use the MAC program that is compatible with ZIP files
good luck!
