Trouble creating Live USB Mac

[1635321]

I am trying to create a live usb I can use to set up my laptop for dual booting (Specifically with Kali Linux)

I am running:

1. OSX Yosmite
2. Macbook Pro 15 inch early 2011
3. 64 bit intel i7
4. 8gb RAM
5. 1TB HDD

What I have tried:

1. Using Disk Utility - Erase flash disk and format as MS DOS (FAT)
2. Using Mac Linux USB Loader - Set up USB using latest version of Kali
3. Restart, holding alt/option
4. Selecting boot from iso, then kali option

I then get the error: live/ vrnlinuz not found
So I tried again with refind

• Get error: disk 'loop' not found

Trying the same steps with Ubuntu worked fine
Plugging in the USB I created to my windows machine worked fine

So then I tried it a different way:

1. Used Disk Utility to wipe USB Drive and set it as FAT partition
2. Using Terminal - diskutil unmountDisk /dev/disk1
3. sudo dd if=lkmini.iso of=/dev/disk1 bs = 512 conv=noerror, sync
4. All the messages back indicate sucess

Reboot

1. In refind select legacy option
2. Error message: No bootable device -- insert boot disk and press any key
3. Then I tried rebooting and holding alt/option
4. Doesn't find flash drive at all

I tried all the steps above multiple times with different iso's. Any help would be GREATLY appreciated!!!!!! Thanks

just few things to add, check the sha1
openssl sha1 (drag & drop iso file)
make sure that the usb is in master boot record
for the dd part, just plain dd(like sudo dd if=lkmini.iso of=/dev/disk1)
press contrl t to see the process
select option again and try to see if there are volumes
if not use refind and look for the linux option(i don't use refind so i can't help)
and if it does not show up, maybe it is because of your firmware(i use a mid 13 pro)
