In This case my SD Card identity device /dev/disk3

Format SD card

I format the SD card as FAT32 giving it the name SDCARD using the following command:

$ 	
sudo diskutil eraseDisk FAT32 SDCARD MBRFormat /dev/disk2

sudo gives me super user rights. diskutil calls the disk utility program. eraseDisk is the command for formating. FAT32 sets the file system. SDCARD is the to be given name of my choice. MBRFormat tells the disk utility program to format with a Master Boot Record. /dev/disk2 is the location of my SD card.

I then am asked for my password. After confirming the formatting is runned.
