basiclly i just bought a mac mini without os. so i need to reinstall the os but i need the firmware password
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 ?
just try that. but it not work. any other way?
i thought that the mac mini late 2011 does had memory battery anymore... but i will looking for it.
I guess. But apple just change policy that they need original purchase receipt to able to do that..... Thanks anyway.
