1. Download  Linux Mint_Mate visit http://www.linuxmint.com/download.php
   (If you want to install the other version, you can. ex) cinnamon, KDE, Xfce)
2.  Open terminal and write under the sentence

hdiutil convert -format UDRW -o /Users/OKSU/Desktop/linuxmint.img /Users/OKSU/Desktop/linuxmint-17.1-mate-64bit.iso

Input (front directory is  img file name, back directory is Linux mint image location.
*'/Users/OKSU'  equal '~')
3.changed image name will be '.img.dmg '. Delete  '.dmg'
4. Terminal command diskutil list   , It finds   /dev/????  of USB   ???
Example)

Oksuui-MacBook-Air:~ OKSU$ diskutil list

/dev/disk0

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *121.3 GB   disk0

   1:                        EFI EFI                     209.7 MB   disk0s1

   2:                  Apple_HFS Mac                     116.4 GB   disk0s2

   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

/dev/disk1  <- * There is USB in my case.

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *7.7 GB     disk1

   1:                        EFI EFI                     209.7 MB   disk1s1

   2:                  Apple_HFS Mint                    7.4 GB     disk1s2

5.  USB unmount in Terminal  (Sleep)
 diskutil unmountDisk /dev/disk[number]
6. Upload Image Files in Terminal 
sudo dd if=~/desktop/ubuntu.img of=/dev/disk[number] bs=1m 
need much times (1~10 mins)  ,then pop up message, click 'unmount'
7. Linux mint can't control apple partition, so you have to leave empty spaces to install Linux mint. I recommend 40GB
8. reboot and push the ALT+OPTION button, then load USB
