Pi hole stuff

  • Download latest Raspbian Lite (currently Buster) from here.

  • Plug SD card into computer.

  • Unzip Raspbian image and install on SD card. This should overwrite everything on the SD card; it shouldn't be necessary to format first.

    diskutil list  # make note of disk of SD card; eg. disk4
diskutil unmountDisk /dev/disk4
sudo dd bs=1m if=<path of raspbian image> of=/dev/rdisk4 conv=sync  # rdisk4 is  faster than disk4
