Apple Event: May 7th at 7 am PT
I forgot the Firmware Password, and want to reset it.
How can I do it?
No DVD included when I bought it.
All the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, does NOT work.
To add or remove DIMMs does NOT work.
Please, give me some helpful answer.
iMac, Mac OS X (10.7.3)
Simply shut down your apple, take out ram if using laptop take out battery as well turn on apple without ram, hold down command ,option,p, and r until apple beeps 3 times after shut down this will bypass the firmware password and allow you to boot from hard drive, CD, DVD, or flash drive check and make sure you reset password sometimes thing resets without needing to do again good luck
That doesn't work on Macs made after 2010.
If the computer has a firmware password set, you will need to contact Apple.
