Great.
You have directory damage. Which os are you using? You should not use your computer until the damage has been repaired. Diskwarrior is what these forums always recommend to repair directory damage. Techtool Pro will work also.
Both need to be purchased.

Macbook Pro will not fully shut down!

Recently my MacBook Pro will not shut down. It looks as if all programs close, the dock disappears, the desktop clears, and then there is the circle of dashes that comes on when the MacBook is turning on. The circle of dashes (I'm sure there's a better name for this!) just keeps going round and round. It will go forever. Eventually I hold down the power button to shut it down. My software is up to date. What's going on?

or if you have another mac with no problems stick that sucker in T mode with a firewier and go throw disk utility from there.
or if you go throw the installation disk dont fully install it as soon as you see the word utility on your tool bar. then hit repair disk.

Is the little LED on your adapter's MagSafe plug glowing when it's connected? What color?
It sounds as though your battery is drained and the adapter isn't charging it. Try resetting the SMC:

That may start the battery charging again.

Itunes is causing my Macbook Pro to freeze at shut down, any ideas?

For a while I was confused as to why my brand new Macbook Pro was failing to shut down. I continued to use it, and each time I would shut my computer off it would freeze with a loading dial in the lower-middle part of the screen. Eventually I started to run one program at a time. I ran Safari (among other programs), and the computer shut down fine. I ran Itunes, and the computer failed to shut down. I have also realized that Microsoft Office causes my computer to freeze at shut down as well. I have run disk utility to check my hard-drive. Everything came out fine, so I know it is not a hardware problem. Something with the software of Microsoft Office and Itunes are not functioning properly... Anybody have any ideas?

My MacBook Pro (2.66GHz Corei7) shuts down by itself continuously

Hi, I am facing the same issue.
Did you able to solve your issue? Please advise.

I plugged in iPhone 5 charger to my MacBook Pro and it immediately shut down and I can't get it restarted. Any ideas how to do this without removing the battery?

If you have your MBP charger, try a SMC reset:

Macbook pro /blue screen after shut down

Hey im running snow leopard on mac book pro .When i try to shut down i get a blue screen with a spinning circle and then it stays there forever .I tried repair with mac os cd , i tried repair disk permissions , disk utility says that everything works fine (no need to repair) . I tried shutting down through safe boot and it works ok.
When im in nornal mode it doesnt shut down . If i turn on and then shut down without opening any applications it works ok , when i proceed using it then ; it doesnt shut down
What do i do ?

i am very frustrated

Core i7 15" MacBook Pro not rebooting or shutting down

Hi All,
My MacBook Pro will not shut down or reboot properly - it sits at the gray screen with the spinning circle.
I have tried resetting the SMC but to no avail and I have to turn off by holding down the power switch.
This has just become more of an issue as I want to install the new SMC firmware update but can't as the machine won't reboot after the update is unpacked and hard rebooting via the power switch cancels the update.
I am running OSX 10.8.2. Any ideas?
Steve

I'll repeat:
You may have directory issues. Shut down. Then boot while holding down the command-r keys until it boots to the ML recovery disk. Select Disk Utility and then run Repair Disk.
Did you do that?

Macbook Pro 17" mid 2009 shuts down on startup

Macbook Pro 17" start acting up few weeks ago. It shuts down at start up. I have to press power button many times to turn it on. I red few posts regarding this problem, and most of them are saying that its HD fault. I've just did fresh install of Mountain Lion with hope it will fix the HD, but I guess it didn't fix anything. Is it possible that SuperDrive is at fault? The reason is that SuperDrive stoped reading CD/DVDs since few months ago. What do I have to do before I replace 500 GB HDD?
Thanks in advance to everyone.

Maybe if you had checked into how to use and repair your system, what to do to reset the system board, and the things that can and do go wrong - PCs are not immune they are different. Notebooks have more trouble with disk drive failures and heat they have to contend with.

Troubleshooting: My computer won't turn on
https://support.apple.com/kb/TS1367
Symptoms
If your Macintosh computer won't turn on, here's how to troubleshoot it. Please keep in mind that although your computer may display similar symptoms that prevent it from showing video, this article discusses what to do if the computer won't turn on, meaning that when you press the power button:
You don't hear a startup chime.
You don't hear any fan or drive noise.
The power button or power indicator doesn't light up at all.
If your computer doesn't display any video, it may display one or more of these similar symptoms when you press the power button:
You may hear a startup chime.
You may hear fan or drive noise.
You may see the power button or power indicator light up.
If any of these conditions occurs, see Troubleshooting: My computer has no video instead.
Resolution
If your computer won't turn on, try each of these steps:
Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
Make sure that the power adapter is properly connected to the power port on the side or back of the computer.
Disconnect all accessories that are plugged into the computer, such as a printer, hub, or other mobile device.
Reset the computer's PMU, SMC, or PRAM. Refer to the instructions for your model:
Portable (iBook or PowerBook)
Mac mini
iMac
Power Mac
Mac Pro
MacBook or MacBook Pro
Other Mac computers

Starts then shuts down

i got home from work yesterday, went to start up my G4 it starts the boot phase with the apple logo and spinning gear and then shuts down.
i tried to reset motherboard, i checked both fans which are spinning (rpms?) but i do notice the heat sink is fairly warm as well as the video card but not sure if that's a normal warm.
i cannot unfortunately boot up to access any log's or system drives.
would disc warrior help? would booting from another OS on an external drive work?
when i hold the option button down to choose the start disc the computer will remain on forever so do i have an overheating issue, but when i select to boot the drive it goes to the apple screen, spinning gear and then shuts down.
help please.

job smith:
Do you get a normal startup chime?
You might try the battery removal advice you read... I'd suggest that perhaps you go a couple of steps further as well, though:
First of all, disconnect your peripheral devices when you're troubleshooting, which will eliminate them from potentially being part of the problem. Troubleshoot with only the keyboard, mouse, monitor, and power cord connected.
Try the following with the Apple Hardware Test disc inserted in the optical drive tray:
Disconnect everything from the Tower.
Disconnect the hard drive(s).
Remove the battery.
Depress the front power button and hold it in for a five-count.
Depress the PMU button and hold it down for a five-count.
Take a thirty minute break to insure the capacitors have drained.
Leave the battery out and the drive disconnected.
Close the side door, hook up and attempt to boot to the AHT disc.
If successful, run it and see what you get.
Reinsert the battery and try booting to the OS 9 or OS X install disc.
If successful, reconnect the startup drive and attempt startup from the install OS X disc again and run Repair Disk and Repair Permissions on the startup drive.
Boot normally to the startup volume.
Any luck? If not, please let us know where things failed.

P7-1597c Commences Starting then Shuts Down

OK this may take a bit; I will start computer with built in graphics running, it will work for a couple of cold starts then try to start and shut down. I will put in my graphics card GE640, the computer will start and work fine I can restart but if I do a cold start it will try to start and shut down; so I will revert back to built in graphics; then install GE630 Graphics Card, computer will start, run fine and same symptom on cold start and the cycle continues. The following are some important additions I have made;
Added SATA Hard Drive
Added 750W Power Supply
Added 8GB Ram (I have 64 bit system)
Using HP 27" Backlit LED Monitor & ACER 24" Monitor
Anyone have any ideas?

MSI Z77-G45 starts then shuts down and restarts

Hi,
I got a brand new MB Z77-G45, with an i5-3470, 2x4Gb Kingston DD3 XMP Blue, and a WD Green SATA 6Gb/s. All that into a Cooler Master N400.
Plugged everything into the MB, powered it and it starts, the 3 fans spin, the frontal led flashes, as well as the 4 leds on the MB but nothing on the screen (with the "no signal" message)
and then shuts down. And restarts again. Shuts down, restarts...
It run with an Advance 600W and all components are new. Any clue?
J.

Good news: a friend brough one stick of DDR3 and it worked! So now, it's just a matter of finding out if the Kingston I bought really is faulty, or if, as you suggested, it's a matter of updating the BIOS.
Either way, I'll post the update and hopefully along a [SOLVED]
Thanks a lot for your input, guys.

My mac book air once turned on goes to the loading screen (the same one as if you turned the mac in for the first time) the wheel turns and behinds to load on the loading bar, it get roughly half way then shuts down?, it never used to go to this loading screen once turned on, it used to go directly to the login area, it happened when I put the laptop on charge although shut it made the booting chime and the apple logo lit up? From then it's done the same thing a constantly shuts down, need help ASAP need the laptop for work on Monday, Thank for any advice anyone can give!

Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

My 17" macbook pro has started to shut itself down or restart for no reason. Can anyone tell me why?

Today for no apparant reason, my macbook pro has been restarting itself.
Has happened 8 times so far, very frustrating since I keep losing whatever I was working on at the time.
L/top runs windows xp because 2 programs I use for work ( CAD and Mapinfo ) don't work on Macs.
Anyone got any bright ideas why this is happening.
Annoying for a PC that cost me best part of $4k.
