Format and Load Raspbian OS to SD Card using MacOS for Raspberry Pi

1. Unmount the SD Card and DO NOT EJECT.

diskutil unmount /dev/disk2s1

2. On your terminal, type diskutil list. Find the disk number of your SD Card. For example disk2. Example

/dev/disk2 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *7.9 GB     disk2
   1:                 DOS_FAT_32 RASPBIAN                7.9 GB     disk2s1

3. Search your Raspberry OS Image file (ex: 2018-06-27-raspbian-stretch.img) and type the following command to load the OS to your SD Card. Please wait as this may take some time to finish. Yeah, no progress bar!:

sudo dd bs=1m if=2018-06-27-raspbian-stretch.img of=/dev/rdisk2 conv=sync

4. Eject the SD Card:

sudo diskutil eject /dev/rdisk2

5. Your SD Card is ready! You can now boot your Raspberry Pi using your newly created Raspbian OS inside your SD Card. Enjoy!

Sample Output:

→ sudo dd bs=1m if=2018-06-27-raspbian-stretch.img of=/dev/rdisk2 conv=sync
