Apr 22, 2012 2:46 PM in response to Scott Mosherby Klaus1,The instructions here:
Resetting your Mac's PRAM and NVRAM:

did not work?

Apr 22, 2012 2:50 PM in response to Klaus1by Scott Mosher,I know how to zap the PRAM, it's just that I CAN'T do this. It no longer works on my Mac. It used to work (and I used to ZAP it periodically) but now I cannot do that. TRYING to zap the PRAM doesn't work, and that is the problem...

Apr 22, 2012 2:54 PM in response to Scott Mosherby Klaus1,What exactly happens when you try? Is there an error message?

Apr 22, 2012 3:46 PM in response to Scott Mosherby WZZZ,If you have a firmware password set, it won't respond to a PRAM reset. Setting a firmware pword requires you to do something; it doesn't happen by itself. But I thought I should mention it.

Might be the keyboard. Do you have another to try? And try the KB in a different USB port.

Apr 22, 2012 5:15 PM in response to Klaus1by Scott Mosher,Nothing happens, it "bypasses" the PRAM chimes and goes right to the start up (account) screen as if it's not even registering the PRAM action. It USED to work previous to my system software upgrade (I'm assuming that update could be a reason behind this being problematic?) The keyboard is the same the Mac came with (the apple keyboard) so I know the issue can't be the keyboard. As I mentioned, the PRAM action just stopped working...

Means nothing that it's the original KB. One or more of those keys may have suddenly stopped working properly. But to pursue another line of thought, what was the update?
Why are you trying to do a PRAM reset? What's the symptom that's prompting that?

Apr 22, 2012 8:30 PM in response to WZZZby Scott Mosher,I zap the PRAM every few months especially when things start seeming a little funky. As far I can tell, the P, R, Command an Option buttons are working fine. The update was from 10.5.6 to 10.5.8. I'm thinking that is a probable (not definite) cause?

Apr 22, 2012 8:37 PM in response to Scott Mosherby WZZZ,★HelpfulI don't see what the update would have to do with this, but try applying the 10.5.8 Combo update from Safe Boot (shift key at the chime.)

What was getting funky? The PRAM reset should only need to be done very rarely. Otherwise, it's just voodoo.

Apr 23, 2012 2:03 PM in response to Scott Mosherby Texas Mac Man,★HelpfulYou can remove the internal PRAM battery for about 10-15 minutes & PRAM will be cleared.
There's not many reasons to zap PRAM, and most of the time it doesn't "fix" any problems.

Nov 29, 2012 12:10 PM in response to Scott Mosherby marysplacestudio,I am running the most up to date version of Mountain Lion, and we have also notice on about four various Macs that none of them will let us zap the pram. Has the keyboard combo (Command-Option-P-R) changed??
