Under the Mac encountered a problem, incredibly unzip the file in this zip format.
or widnows on top of it. After decompression, the file has 4G.

Simple click on the line.

2), view disk

$DF-LHFilesystem     Size   used  Avail capacity  iused   ifree %iused mounted on/Dev/Disk1    233Gi  215Gi    -Gi     the% 56386271 4592543 92%//Dev/disk2s1    -Gi  1.6Mi    -Gi     1% 0 0 100%/volumes/21 1

Remember that the disk is called/DEV/DISK2S1.
Unmount the disk before writing the image file.

$ sudo diskutil umount /dev/disk2s1                                21on disk2s1 unmounted

It then starts writing to the file. (pay special attention to writing files without S1 and the previous r,/dev/disk2s1 corresponding output file is/dev/rdisk2)

$ sudo dd BS=1Mif=./ -- the- --raspbian-jessie.IMG of=/dev/rdisk24125+0 Records inch4125+0 RecordsOut4325376000 bytesTransferredinch 401.205151secs (10780958 bytes/SEC)

After the file is written successfully, you can see a more boot disk in Disk Management, indicating that the file was successfully written.
