Wait a minute, then reconnect to the Raspberry Pi (the `ssh` command above) and run the final setup script: `sudo shutdown -r now`Īt this point you've updated the software on the Pi and have restarted to let the updates take effect. `sudo apt-get upgrade` (Choose `Y` when prompted) 3. Run the following commands in the SSH session you just launched:ġ. Now, you're ready to update the Raspberry Pi's software.

`ssh this case, your username is `pi` - the default password is `raspberry`. To connect to your Raspberry Pi, type the following command at the terminal (replacing the IP address with the one you discovered in the previous step): One last step! We need to connect to the Raspberry Pi and complete the setup.

Note - Again - be careful! Make sure you use the correct device name here! Using the wrong device name could delete everything on your computer. Received an error with that command? Drop the `r`, and use the `/dev/diskX` device instead. Including the `r` will make it write faster.

Replace the device name with the disk number you used in the previous step, but replacing `/dev/diskX` with `/dev/rdiskX`. To determine the exact command you need, replace the file name after `if=` with the name of the image you extracted earlier. Run a command similar to this to write the image file to your SD card: `sudo dd bs=1m if=-raspbian-jessie-lite.img of=/dev/rdisk2` Change to the directory where you extracted the image file (`cd ~/Downloads` for your Downloads directory) 3. Once Raspbian is downloaded, it's time to write it to your SD card:ġ. Expand the file that you downloaded and make note of where you expanded it I recommend the 'Lite' version for headless applications (like BrewPi), but use the version you are comfortable with. Download the version of Raspbian you prefer. Go to: in a web browser of your choice 2. If you select the wrong disk, you may end up damaging your computer. It is almost certainly not disk0 and is probably not disk1. Note - Be careful! Before you proceed, make sure the disk name you selected is correct. Unmount the disk by typing `diskutil unmountDisk /dev/disk2` (replacing disk2 with the disk identifier of your SD card) Review the list and find the SD card device name (Will be something similar to `/dev/disk2`) - Look for the device that is the size of the SD card you are using 3. Once you've launched the terminal, locate the device name & unmount the disk:ġ. Insert your SD card into a card reader attached to your computer (using a Micro SD adapter if necessary). The first thing you need to do after collecting your materials is hook up your SD card and prepare to install the software.
