Old Harry,
I am using a Late 2007 Aluminum IMac with Leopard. I always install by download and dragging the Carbonite, CarboniteNodes, and CarboniteTransfer folders into the Applications/World of Warcraft/INterface/Addons folder in Finder. My files are always automatically uncompressed for me. I use stuffit 12 for decompression and have no issues.
Hope this helps.
