Headless Setup of Raspberry Pi Zero W (Raspberry Pi 3 Wireless) (macOS).markdown

#Headless Setup of Raspberry Pi Zero W (Raspberry Pi 3 Wireless) (macOS)

1. Formatt the Micro SD card - Open a terminal and type 'diskutil list'. Find your card and copy the disk name (For example: /dev/disk4). Format the card with diskutil eraseDisk ExFat temp disk4(Use your disk here)
2. Download Raspbian - wget https://downloads.raspberrypi.org/raspbian_lite_latest
3. Unmount the SD card - diskutil unmountDisk /dev/disk4 or whatever your disk path is
4. Mount the Raspbian image to the card - sudo dd if=PATH-TO-RASPBIAN-IMAGE of=/dev/disk4` or whatever your disk path is
5. Enable SSH on the Pi - cd /volumes && ls. You should see a boot partition from the SD card cd boot && touch ssh
6. Setup WiFi on the PI - While still in the boot partition of the card type nano wpa_supplicant.conf and enter network={ ssid="YOUR-SSID" psk="YOUR-WIFI-PASSWORD" }
7. Boot the PI - Unmount the card diskutil unmountDisk /dev/disk4 (or whatever your disk path is) and put it in the Pi, then power up the Pi
8. SSH Into the Pi - Find the Pi's IP on your network by running arp -a or using an app like LanScan and ssh into it ssh pi@YOUR_PIS-IP. THe default password is raspberry
9. Add your SSH key to the PI - While in the Pi run install -d -m 700 ~/.ssh. On you machine run cat ~/.ssh/id_rsa.pub | ssh <USERNAME>@<IP-ADDRESS> 'cat >> .ssh/authorized_keys'

@antenorr - Raspbian checks the contents of the boot directory for a few specific files at startup:

• If it detects wpa_supplicant.conf, Raspbian moves the file into /etc/wpa_supplicant, overwriting any existing wpa_supplicant.conf file in there.
• If an empty file named ssh is detected, Raspbian adjusts it's settings to accept SSH connections, and deletes the file.

Also, if you're using 'Stretch' you need to include the full wpa text in your wpa_supplicant.conf file:

wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
	ssid="your-network-service-set-identifier"
	psk="your-network-WPA/WPA2-security-passphrase"
	key_mgmt=WPA-PSK
}

Got this working on Mac with an SDXC 64GB card. Worked on OS X 10.13.4.

The first few steps should be slightly different:

• Download OS: https://downloads.raspberrypi.org/raspbian_lite_latest
• You should now have a .ZIP file. Unzip OS. You should now have an .img file.
• Format card: diskutil eraseDisk FAT32 TEMP MBRFormat /dev/disk3 // DOUBLE-CHECK DEVICE NAME

I think it is important to note that by saving your wpa_supplicant.conf with "YOUR-WIFI-PASSWORD" in step 6, your pi will store your wifi password in plain text. If security isn't a major concern, then ignore this, but in case you'd like to change this, I suggest you read the "Connecting with wpa_passphrase" section of this wiki article:

Hey Caleb i was wondering how can i assigned an Static IP Address to the PI once i set this one over the WIFI correctly?

How do you do this on a public network?

Hope this helps someone else...

I tried this and it wasn't working. I eventually figured out that my issue was that my WiFi router supports both:

• Wireless Network (2.4GHz b/g/n), and
• Wireless Network (5GHz a/n/ac)

Using a 5GHz a/n/ac network failed, but using the 2.4GHz b/g/n worked!
Make sure you're NOT using a 5GHz network for your ssid network name.
