how to check avaliable wifi ssids without network-manager:

1

sudo iwlist wlan0 scan | grep ESSID

default login (maybe not):

1

3

username: pi
password: raspberry

in order to start sshd, touch ssh under boot partition

recover dhcpcd service:

1

3

sudo systemctl enable dhcpcd.service
sudo systemctl restart dhcpcd.service

config the password with proot -S <path_to_rootfs> -b <boot_partition>:/boot -q qemu-arm /usr/bin/bash and passwd

you’ve installed raspap on this device. you use the default credentials. this shit will not connect to our wifi automatically, thus block your way of running docker containers on it with only macbook.

seriously? do you really need docker on macos? or just on raspberry pi?

change apt sources:
