Customer Question
When I power on...

When I power on my mac book pro, all I get is a blank screen with a flashing grey folder that has a question mark in it. What does this mean and how can I fix it? I have already tried turning it off and back on but that hasn't changed anything.

Technician's Assistant: Have you tried a PRAM reset on your MacBook Pro (rebooting and holding down Command, Option, P, and R)? Or rebooting in Recovery Mode (holding down Command and R)?

PRAM reset didn't work, however I am getting somewhere with the reboot in recovery mode. I have a spinning globe with a bar half way done loading.

Technician's Assistant: Anything else you want the Mac Expert to know before I connect you?

Nothing I can think of. Thank you for the help.

Thank you for your question. My name is ***** ***** I look forward to assisting you.

Shut down your Mac.
Find Command (⌘), Option, P, and R on your keyboard.
Turn on your Mac.
Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
Hold these keys until the computer restarts and you hear the startup sound for a second time.
Release the keys.

Tell me if it then starts please

What Customers are Saying:

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
