This guide shows you how to flash SD cards to mount files, specifically
.img files for Raspberry Pi, Android TV Shield, and any other device. Make sure your SD card is empty. If not, you can use Mac’s disk utility application to erase the contents of your SD card.

3. Navigate to the directory of the file you want to flash and type in:
sudo dd if= of= bs=8m
bs is the block size of bytes to write or read. You can put (almost) any number here. I just did 8.
