Clone Raspberry Pi SD Card on a Mac

Pretty easy, but takes a LONG time (32GB took 3 hours to backup and 10 hours to restore via my iMac).

Open the terminal and find your disk id#. Run:

 

diskutil list

To Back It Up

sudo dd if=/dev/disk2 of=~/Desktop/raspberrypi.dmg

 

To Restore

diskutil unmountDisk /dev/disk2

sudo dd if=~/Desktop/raspberrypi.dmg of=/dev/disk2
