Install Rasbian

Most of the time I use a headless Raspberry Pi which I want to access via ssh. These are the steps to do that.

1. Download Rasbian
2. Install the downloaded file on a SD card

• Find the disk number of the SD card with diskutil list
• Unmount the disk with diskutil unmountDisk /dev/disk<number>
• Copy data on the SD card with sudo dd bs=1m if=<img-file> of=/dev/rdisk<number> conv=sync
