插入SD卡，用df命令查看当前已挂载的卷

$ df -h

使用diskutil unmount将这些分区卸载

$ diskutil unmount /dev/disk1s1
Volume NO NAME on disk1s1 unmounted

通过diskutil list来确认设备

$ diskutil list
/dev/disk0

   1:                 DOS_FAT_32 NO NAME                 7.9 GB     disk1s1

使用dd命令将系统镜像写入。

/dev/disk1s1是分区，/dev/disk1是块设备，/dev/rdisk1是原始字符设备。
$ sudo dd bs=4m if=2014-01-07-wheezy-raspbian.img of=/dev/rdisk1
706+1 records in
706+1 records out
2962227200 bytes transferred in 470.754370 secs (6292511 bytes/sec)

diskutil unmountDisk卸载设备

$ diskutil unmountDisk /dev/disk1
Unmount of all volumes on disk1 was successful
