Lion uses the + R to boot into recovery mode. Resetting the PRAM in anything less than 10.7 was + + P + R.

Recovery mode now seems to override the PRAM command. Does anyone know if there is a new way to reset the PRAM now that Lion is installed?

    It's a matter of timing. You need to push these key immediately after turning on. If you wait too long, the bootloader is already active, which uses Cmd+R for the recovery function. – René Aug 9 '11 at 7:18
  • If you have the option, try using a (different) external, wired keyboard. If the reset PRAM shortcut works, then maybe it's something with the original keyboard? – Zonker.in.Geneva Jan 25 '17 at 15:21

Resetting the PRAM works the same way it always did. This is a function of the hardware - not the OS. What makes you think it doesn't work anymore? (tested on Macbook, Mac Mini).

  • I tried it 4 times on my wife's MacBook and it booted into recovery mode each time. – Nate Bird Aug 9 '11 at 14:35

Nate , PRAM reset is not working because you turn on Password Firmware Protection. Turn it off and P+R+Option+Command will work.


Or she has spilt something on the keyboard and the shift key is telling the computer it's being held down, so no matter what, it will boot into recovery mode. I work for an apple specialist and see it all the time.
