I have two applications on *Mac* to create a backup of your SD card *(PiCloner)* and another that is a graphical interface to copy the operating system from the *.img* file to *SD (PiWriter).*
Remember the right way to do the same as *PiWriter* in the Mac Terminal:
N is the drive of your SD card
$ diskutil list
$ sudo diskutil unmountDisk /dev/diskN
$ date +'Start: %H:%M:%S' && sudo dd if=myImage.img bs=1m of=/dev/rdiskN
$ diskutil eject /dev/diskN
