PiCloner is a simple interface that helps you create backup images of your RaspberryPi's SD card on Mac OSX. These images can be restored to your Pi with PiWriter or any other bit-copy software.
PiCloner will be replaced by PiWriter2 starting version 2.x. Version 1.0.4 will be the final release of PiCloner as it is.
Get PiWriter2 from: http://sourceforge.net/projects/piwriter/files/PiWriter-2.x
Does not Work on MacOS Sierra.
