 It is easy to make a backup of your SD card on a Macintosh.  All the programs and utilities you need to do it, are included with OS X.  You will need to use the terminal, which works very much like the bash shell on the node itself.  Terminal is found in the Applications/Utilities folder on the Mac.
-THe instructions below assume you have become root on the Mac. The root account is deactivated by default on new Macs. But it can be activated. See  http://support.apple.com/kb/PH11331 for information on how to do that. Once activated, you can become root with 'su -'  (just like on the node).  Without the root account active, you will have to precede all the commands below with a 'sudo'.   Be VERY CAREFUL with the root account, or even sudo.  You can very easily destroy your Mac OS X installation with a single keystroke.

 The process described below is a two step maneuver. The first part creates an image file copy of the SD drive, on your local hard disk. The second part copies that image file to a new SD card in the slot.  If you need to make more than one copy, simply perform the second part more than once.
