Customer Question
I have a 27"...

I have a 27" iMac that is about 7 years old. I am getting a prohibition screen. I'm trying to get it to a place where I can restore from the Time Machine backiup

Technician's Assistant: What Operating System (OS) are you running on your iMac?

I don't know. I never upgraded it. It would be whatever OS iMacs shipped with around 2009 -2010

Technician's Assistant: How long has this been going on with your iMac? What have you tried so far?

Several weeks. We've purchased an external drive to restore the Time Machine to. I tried booting using (I think) Control-Option-R, but it just keeps going to the prohibition screen

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

Unfortunately, I don't have any other information to give

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
