To resolve this problem, power off your computer and then, switch it back on, while holding down the [command] + [option] + [P] + [R] keys at the same time. You need to continue holding the keys down until you hear the second Apple chime to clear the PRAM.

Sometimes, your Apple computer does not boot properly, due to a problem with an extension. In such cases, restart or power on your computer, while holding down the [shift] key.

Connect one end to the Mac that needs data recovery, say “Mac A” and the other end to the Mac that is going to store the recovered data, say “Mac B”. Switch on Mac A while holding back the keyboard letter [T]. The boot process starts Target Disk Mode and will load the contents of the hard drive on Mac B.
