Hi people, previously I has been trying to install Kali Linux on my usb. I found this site and follow it (https://forums.kali.org/showthread.php?303-Kali-Linux-install-to-USB-key-using-Mac) Now here is the problem, I have used the command Code: sudo dd if=kali.dmg of=/dev/rdisk1 bs=512k which I think it change or replace my OS X main drive. I still believe that my OS X drive still exist because the "hard drive" icon that I modified still appeared on the screen. I decided to check all the drive on my laptop and here is the result using Code: df on terminal and here is the result. Does any if these is my OS X that has been replaced? ps. I checked this by install new OS X on external hard drive.
