1. Macbook 电脑用于烧录树莓派系统到SD卡
2. 树莓派 zero w
把SD卡放进读卡器，插到Mac电脑上， 打开命令行工具Terminal
diskutil list列出disk列表
diskutil unmountDisk 设备名称
dd命令烧录
MacBook-Pro Volumes$ diskutil list

MacBook-Pro Volumes$ diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful
MacBook-Pro Volumes$ sudo dd if=/Users/klaus/Downloads/2019-07-10-raspbian-buster-lite.img of=/dev/disk2 bs=1m
烧录结束后，boot分区会自动挂载到Mac上
在boot分区上添加两个文件, ssh 文件是一个空文件，在系统启动后，系统会根据这个文件开启系统的SSh服务，wpa_supplicant.conf文件会让系统配置该文件内的WIFI信息
ssh
wpa_supplicant.conf
country=CN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="WIFI_SSID"
scan_ssid=1
psk="WIFI_PASSWORD"
key_mgmt=WPA-PSK
}
系统启动后，通过路由器找到树莓派的IP，默认用户名是pi, 默认密码是raspberry
