Can you clarify? Are you asking how to change it?
Customer: replied 1 year ago.

basiclly i just bought a mac mini without os. so i need to reinstall the os but i need the firmware password


 

Expert:  Mike replied 1 year ago.
Basically, this means that a previous owner of the machine decided to lock it, and this lock will prevent you from booting to other drives, optical media, etc. Since you don't know the password, there is a procedure to override it: You need to change the amount of RAM in the machine (either add memory or remove existing memory in the expansion slot), and IMMEDIATELY, i.e. the first time booting after changing the RAM, reset the PRAM (Press and hold the Command-Option-P-R keys before the gray screen appears) three times in a row. That means it needs to chime three times after the power-on chime. Once you've done this, you should no longer see the lock.

the first time booting after changing the RAM, reset the PRAM (Press and hold the Command-Option-P-R keys before the gray screen appears) three times in a row




By that, you mean i need to turn on & off three times ? or PRAM 3 times after the first power up ?

Expert:  Mike replied 1 year ago.
No hold those keys IMMEDIATELY after you hear the startup chime and keep holding them until you hear the chime 3 times more then let go.
Customer: replied 1 year ago.

just try that. but it not work. any other way?

Expert:  Mike replied 1 year ago.
There should be a battery that keeps the internal memory, remove it for about 10 minutes that should clear it. Let me know
Customer: replied 1 year ago.

Expert:  Mike replied 1 year ago.

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
