ErnestAgyare :

my name is XXXXX XXXXX can assist

ErnestAgyare :

the error you are en-counting can be corrected one of two ways

ErnestAgyare :

by reseting you pram and smc

ErnestAgyare :

or restoring your operating system through your utility cd

ErnestAgyare :

i have instructions available for both

Customer :

How do you reset PRAM andsmc

Customer :

How do you reset pram and smc?

ErnestAgyare :

Resetting NVRAM / PRAM



  1. Shut down your Mac.

  2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.

  3. Turn on the computer.

  4. Press and hold the Command-Option-P-R keys before the gray screen appears.

  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.

  6. Release the keys.

Customer :

OK, I see 6 steps. How can I get back to you if the fix fauls?

ErnestAgyare :

please simply log back in i will be on standby...DO NOT RATE...untill your issue is solved

ErnestAgyare :

you also need to delete the preferences for system preferences, they're in:
mac hd> users> your username> library> preferences>delete file: com.apple.systempreferences.plist

Customer :

OK, but how do I log back in and contact you"

ErnestAgyare :

the same way you contacted me before the box will be open

ErnestAgyare :

also please look at this software which may help as well

ErnestAgyare :

im trying to give you all the options i have before you do a system restore with utility cd

Customer :

Sorry, your answer is not clear. I do not have a record if how I started the contact.

ErnestAgyare :

please log back in to justanswer.com

ErnestAgyare :

and you will be able to access me again i will be on standby

Customer :

This part of your system us nit very clear/

Customer :

Is there some ID number that will identify my question?

ErnestAgyare :

im an expert so i get the expert screen but im sure you can get back to me because alot of customers have

ErnestAgyare :

do you see a tab up top that says my questions?

Customer :

No tab on top is seen

Customer :

Not your fault

ErnestAgyare :

i apologize i have never seen a customers screen just the experts

ErnestAgyare :

either way i will be on standby

Customer :

OK, I will go now, and follow your directions a little latter

ErnestAgyare :

no problem please remember only rate me when you issue is solved if its not come back to me for further assistance

Customer :

Solution did not work

Customer :

Still get crash report fo failure.

Customer :

Please respond

ErnestAgyare :

it is simply not possible sir? according to the manufacturer apple...https://discussions.apple.com/thread/3975936?start=0&tstart=0....this is the link proving it....please by all means let me know if you want another expert....but i am here with 3 experts saying the same thing apple is saying

Customer :

Tried suggestion again.

Customer :

Solution does not work, Same problem remains

ErnestAgyare :

you will need to utility cd to reboot your system

Customer :

utility cd disk long gone,

ErnestAgyare :

you need that to restore it...it seems that you will need to reload you operating

Customer :

Can I download from Apple if you supply URL

ErnestAgyare :

no you will need the actual cd because you will need to boot it from the start of you computer

ErnestAgyare :

when you download it ...it will not be available at the beginning of your start up...cd only

Customer :

In that case, I will upgrade system to v. 10.8 mountain lion. I do not believe I shoild pay, as you did not solve problem. The system upgrade is less expensive than the expert advice (which did not work)

ErnestAgyare :

well you issue can be solve only one way which i provided you...you may visit the apple store which will tell you the same...so i indeed did identify your issue and give you a solution. Which is what we are here for...we can either troubleshoot and if the issue is beyond us..we can pin point the issue and tell you the remedy....which i did...

ErnestAgyare :

so if you dont want to RATE ME for my assistance i am completely fine with that ...no problem

Customer :

I will be happy to rate you as OK, but again, the charge is not worth the advice. I could have carried out an upgrade without your expert advice.

ErnestAgyare :

an ok rating is fine with me

ErnestAgyare :

is there anything i can assist you with before you rate me

Customer :

I already sent in my rating. Was it received?

ErnestAgyare :

i dont know i cant see it im more concerned with helping

  • 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
