SD Card Burning and Duplicating¶
Burn an SD card with OSX¶
Use Etcher to burn an image file to an SD card.
Duplicate an SD card with OSX¶
Insert an SD card and determine the mount point with:
Unmount (NOT eject) the SD card disk with:
diskutil unmountDisk /dev/diskX
sudo dd if=/dev/rdiskX of=~/images/raspberrypi.img bs=1m
Notice the use of rdisk2 instead of disk2. Also the dd command can take a long time to complete and provides no visual feedback on its progress.
After creating the .img file, use Etcher to burn the image file to an SD card.
