Yes,you can use HTTrack on your Mac from a command line user interface. 

You will have to install Apples Developer Tools (found on your install DVD, I
think) and type some commands to compile HTTrack from source code. 

See this post on how to do so:

And if nessicary, feel free to post here for further help using HTTrack on
your new Mac. :-)
