Wayback Machine Downloader
This works on the Mac too, and probably on Windoze too, altho I've never tried to install on that platform.
The Wayback Machine is a digital archive of the World Wide Web and other information on the Internet created by the Internet Archive, a nonprofit organization.
Since 1996, the Wayback Machine has been archiving cached pages of websites onto its large cluster of Linux nodes.
The intent is to capture and archive content that otherwise would be lost whenever a site is changed or closed down. The overall vision of the machine's creators is to archive the entire Internet.
How to Access It?
If you just want to see an old website, or for instance how Apple's website looked in 1998, well all you have to do is access http://www.archive.org and type in the site's url.
Downloading Entire Snapshots
On the other hand if you wish to download a site (one or more snapshots) you can use the Wayback Machine Downloader. It is written in Ruby, and you can install it using gem. You'll need Ruby >= 1.9.2 to use it.
To install it issue a:
sudo gem install wayback_machine_downloader
