Do not Enter sign

Hello, Upon booting up my Macbook Pro, my computer one day I had a do not enter sign on my screen. I did what support on the internet told me to and getting rid of it just isn't working. I get to where the spinning globe in going on the screen, I put in the WiFi password and it goes to the Apple logo but it never makes it to the Utilities screen. It loads one time than goes to another Apple logo and when it's almost done it gets hung up. I tried to reset the computer with Command "S" But after it loads and I try to type in stuff it just sits there and than the wording becomes all scrambled and has the do not enter sign in the background. I am attaching a photo here. I am hoping to fix this. I tried taking it into a repair shop but they don't even know actually what's wrong and wants $300.00 to figure it out and fix it. My Mac has been out of commission for three weeks now. Any help would be appreciated.

according to Apple:


Prohibitory symbol

A circle with a line or slash through it means that the selected startup disk contains a Mac operating system, but it's not a macOS that your Mac can use. You should reinstall macOS on that disk.

I usually say, your Mac was in the process of booting up, when a major component of MacOS was found to be damaged, and proceeding is not possible.


The conclusion is the same: DO NOT erase your drive. Re-Install MacOS in place, right over the existing version (which by design, does not remove your files or added Applications).

HI, The issue Macbook Pro never came with a disk so I can't reinstall.

the Installer DVDs had a stripped-down version of MacOS to run the Install, the additional files needed for a full system, and a set of Utilities, including Disk Utility.


On older Macs running 10.7 and later, that stuff (except for the Install image) was placed in a special partition that was bootable, called Recovery HD. After 2011, MacBook Pro had the minimal MacOS, and a way to download everything else from the Internet as a Part of its ROM. This variety is called Internet Recovery.


So to get those Utilities, you hold Command-R at startup, and wait. Soon you will see some activity and messages, and will either get a choice of about six items, or have a Utilities pull-down menu from which you can select Disk Utility.

HI, The issue Macbook Pro never came with a disk so I can't reinstall. Or I would have already done this. I've tried everything. I am reading what you cut and paste for me but I have read this as well. Before I even posted on the board I looked at all the information I can . As you can see from above I even tried to do a factory reset on it and the words became jumbled and than the sign shows up behind it so I can't even do that much. Is there any hope for this or is my computer shot?

HI, I have tried all these things and I never get a utilities menu at all. It goes to the Apple Logo and it does nothing than I try it another way and it shows a spinning globe and I put in my WiFi and nothing. That's my issue I can't get the utilities screen to come up to do anything.

Hi, So I tried to do the reinstall of my operating system which is Mac OS X 10.7, again it shows me the drives than when I try and do what it states to do it still ges to the do not enter sign screen after the apple logo loads. I just don't understand what could have happened to make it so bad.
