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)
