The USB disks are always at the bottom. You can see mine is listed as:

In most cases, the IDENTIFIER for your USB flash drive is something else. In my case, it is disk3

Make sure to note your correct IDENTIFIER, otherwise u gon erase the wrong disk.

6. Erase USB flash drive using Terminal

In Terminal, type diskutil eraseDisk JHFS+ "USB" GPT /dev/disk3 but replace disk3 with your IDENTIFIER. Press enter. POOF there goes your data.

It gon look like dis:

7. Copy the “efi” folder to the USB drive

Recall that our USB flash drive was renamed to USB in the erase process.

In Terminal, type cp -R /Volumes/rEFIt/efi /Volumes/USB and press enter

Then, cd /Volumes/USB/efi/refit/ and press enter

Then, sudo ./enable.sh and press enter

Your password ain’t gonna show, but type it in and press enter anyway. Why? Because security.

Should look like this:

Done.

Eject the USB flash drive like you normally would, then reboot your Mac while holding the option key, and you should see rEFIt as an option.
