Hi Jim – Mac is actually the preferred platform. Windows users need to install Cygwin to get a Linux-like environment for running Hadoop, but Mac already has that – you can just use the regular Terminal window.

The instructions for lab appear to assume a windows user. Are the tools required already installed for a mac? Is there a preference on a windows vs mac set up?
