# Run it in a terminal in the "boot" directory of the flashed MicroSD card

|
|
# cd /Volumes/boot (or wherever the boot folder is mounted)

# chmod+x update-rpi-mac-linux.sh (if not executable already)
|
|
# ./update-rpi-mac-linux.sh
|
|
#
|

# Put the card in your Pi, and reboot!
|
|
|
|
# Creates the ssh file if needed, since Raspbian now disables
|
|
# ssh by default if the file isn't present
