On your Mac download and install the Raspberry Pi Imager application.
Insert a SD card or USB drive into you Mac. Select "Raspberry Pi OS Lite" and click "WRITE".
Once the OS is downloaded:
cd /Volumes/boot
touch wpa_supplicant.conf
Insert the following into wpa_supplicant.conf:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB
network={
ssid="wifi network name"
psk="wifi password"
}
To enable SSH access to the Pi:
cd /Volumes/boot
touch ssh
Remove the SD card/USB drive, insert it into the Pi and power it up.
After a few minutes, you can SSH into the Pi with:
ssh -p 22 pi@raspberrypi.local
The default password is raspberry.
Once SSH'd, change the password with passwd.
To avoid entering a password every time, copy the contents of a public key on your Mac e.g. ~/.ssh/id_rsa.pub, and paste it into a file called ~/.ssh/authorized_keys on the Pi.
On your Mac, add the following entry to your ~/.ssh/config file:
Host pi
Hostname raspberrypi.local
IdentityFile ~/.ssh/id_rsa
User pi
Port 22
You can now SSH into the device with:
ssh pi
sudo su -
adduser imran
usermod -a -G adm,dialout,cdrom,sudo,audio,video,plugdev,games,users,input,netdev,gpio,i2c,spi imran
# exit and run `ssh -p 22 imran@raspberrypi.local`
sudo su -
pkill -u pi
deluser -remove-home pi
sudo su -
visudo /etc/sudoers.d/010_pi-nopasswd
# replace with `imran ALL=(ALL) PASSWD: ALL`
mkdir /home/imran/.ssh
