My MacBook Pro starts and shuts off after loading for sometime

Try starting in Safe mode by holding down the Shift key while booting. Safe mode takes a while to load the OS. After that, restart the computer normally.
If that does not work, start up in Recovery by holding down the Command and R keys. In the window that opens, choose Disk Utility at the bottom and verify and repair your disk. Repair permissions while you are there.

Macbook Pro starts up, has a small loading bar, and then shuts off.

Macbook Pro starts up, has a small loading bar, and then shuts off after a few seconds, but the Windows bootcamp partition works fine.
The repair disc option (using install disc) failed, and the computer cannot locate the original Mac side partition. Only Bootcamp appears under options to "restore from backup" or reinstall. The repair disc options says it should be repaired but doesn't seem to know how.

Bootcamped with Windows.
Any ideas?

Hold c or option key and boot off the 10.6 installer disk, run DU Repair from there.

Step by Step to fix your Mac
If it doens't work, you can recover files if you don't have any current OS X file backups, then grab what you can out of Bootcamp
Use Data Rescue installed on the extenral boot drive ($100) to read the bits of the internal (non-filevaulted) drive to retrieve OS X data files if you can't get them off manually via drag and drop methods.
Create a data recovery, undelete boot drive
If you want to clone Windows, use WinClone and another drive. However it's likely compromised, unless it something you did in Windows, like trying to create a new parttition perhaps?
Then perform a Zero Erase and install of 10.6 as shown here (on the entire drive, not only the parittions), this will give a new GUID partition table, EFI and map off bad sectors, totally fresh everything.
How to erase and install Snow Leopard 10.6
You cna use Carbon Copy Cloner to clone the new extenral setup to the new scrubbed internal drive. Recreate Bootcamp and WinClone back or fresh install Windows into Bootcamp like before. OR opt to use virtual machine software which is safer.
Windows in BootCamp or Virtual Machine?
Windows 7 can write to the boot drives GUID partition map (unlike XP), this is likely why it's borked now.

Won't boot unless I hold the power button and shuts off after closing

My mac book pro (current gen) shuts off after closing the screen and won't start up unless I hold the power button for about 10 secs.
Any suggestions?

Do a SMC and PRAM reset and read this guide

My macbook pro has been shutting off on its own. The power cord "shuts off" (does not work) simultaneously. Does anyone know what is wrong? or what could be the problem?

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.

6 digits sounds like the code sent from Find My Mac when locking the machine. It can only be reset by an Apple Store.

MacBook is starting to shut down after 5 minutes.

My MacBook has just started to shut down after 5-10 minutes. The computer still holds a charge, and the battery Percentage says that it's full, so I dont know what's going on.

If it's under AppleCare take it in immediately.
It is possible that a fan might not be working, and causing it to overheat & shutdown as a safety measure.
The other reason could be RAM.
But that's just my guess.

My macbook pro turns on and shuts off after about thirty seconds

After force shutting my computer by holding the on button, my macbook pro will not start up anymore. It displays the loading screen for around thirty to forty seconds, but shuts off immediately after that. My battery is in good condition and works fine.
Does anyone know how to fix this?

Hi ltksm,
If you are having issues with your MacBook Pro shutting down unexpectedly, you may want to try resetting the SMC (System Management Controller). You may find the following article helpful:

Why is my 2010 macbook pro freezing and shutting down every time I start it?

Today, after using my macbook pro to upload pictures from my iphone, my computer started having problems and shutting down. The screen goes gray and a box pops up saying that a problem exists and that I need to restart my computer. I've only had the macbook since last November, so I don't understand why I've been having so many problems with it. This happened a few times to a lesser extent in Senegal when I was there for 5 months. I used a mac power adapter so I don't think it could be an over-charge problem.
Please help!

Sounds like your iphone is causing kernal panics.
Unplug everything. Keyboards, mice, external hard drives, the lot.
One of these devices could be causing it.
Then, grab your Install DVD, and boot while holding the C button.
Select your language.
Go to Utilities > Disk Utility > Repair Disk + Repair Permissions
Then restart, and every once in a while, add one of the keyboards/mice/iphones/hdd's one by one to see if they are causing issues & therefore identifying the culprit.

MacBook Pro Mid 2014 shut off randomly and won't turn back on.

Hello,
My MacBook Pro(Mid 2014) won't turn back on. I was just typing up my essay and it just turned straight off and won't turn back on. It has happen several times before and all I had to do was press the buttons(SMC method) and the PVRAM thing and it would turn back on. But now it doesn't turn on at all. How do I fix this issue? I had went today to the Apple Store and had a appointment at 3:15-3:25 and I was late by 2 minutes, so they couldn't help me and offered me to come back at 5PM, but will busy so I asked for 5 Monday. Does anyone know what the problem might be? Back when it was operating it would shut off whenever I was using it at the random times. This is my first MacBook so I don't know if it's suppose to get Hot and loud sometimes when operating and then cool off afterwards if that helps out. It shutoff last week wednesday and doesn't turn on at all, but will charge to fully green though. Anyone got any suggestions? I do have a MacBook screwdriver to open it, so if anyone knows anything about the inside and how to resolve the issue it would be great. I don't know how to remove the battery so if you do know please tell me or some keyboard trick would be helpful! All my data is on this so I would like to solve before Apple erases my data.

Black macbook gets to spinning gear and shuts off after almost a minute

Hello All,
this is my first post as it is the first time i haven't found specific answers elsewhere.
My Macbook will go to the grey screen with logo and gear for 30 seconds and i have tried the following.
I have tried to reset the ram with the command function i forget the keys like p r or something, and i finally got the bong noise.
this still didnt help so i tried to get into safe after this noise with the left shift key, and once i let go at the gear, it still shut down after around half a minute 45 seconds.
I then booted into verbose to see what was really causing this shut down after this.
this was the last couple of lines it froze up on before shutting down.
[HCIController][configurePM] power parent ready after 1 tries
[AppleIntelCPUPowerManagement: initialization complete
disk0s2: I/0 error.
disk0s2: I/0 error.
syncing disks... killing all processes
continuing
done
CPU halted
it usually freezes on the line disk0s2:I/0 error for about a mintue, and once the last run from the second I/0 error to the CPU halted rolls onscreen it is around 3 seconds before it shuts down.
For the last i dont know 3 weeks i have gotten every once in a while these messages saying my startup disk was full, even though i had 37 gigs left on the hard drive.
the reason i got here was because i was trying to copy some files from my compact flash recorder to my computer for listening and maybe 10 of the 15 copied and said the rest could not be transferred because of the disk being full. At this point i decided to restart, and it would not come back to desktop. ANY HELP anyone?
thank you so much

Hi,
I'm not really an expert at anything like this, but from the looks of things, it can read the hard disk up until a certain point and then gets an input/output error, can't read the hard disks and just shuts down. If you have a Boot Camp partition, try booting that, it helped me recover some stuff. Or if you have a firewire cable and a computer with a firewire port, connect the two together and hold T when booting up your Mac. If the other computer is a PC w/ Windows, you may have to install HFS drivers like MacDrive (there is a trial, google it), and see if you can copy off any of your files. You could also try an archive and install by booting up from the Mac OS CD that either came with your computer, or if you bought an upgrade disc. If that fails, then your disk is probably dead. If your Mac is still under warranty, try taking it to an Apple Store / authorised service centre etc, some place they will fix it. However, if your Mac is booting up to a certain point, it could be dead software not hardware.

Macbook pro 13" 2012 shut off randomly and won't turn on

The only applications that were open were safari (I was watching hulu) and iTunes. The laptop randomly shut off without any warning. It was in the charger and was around 60-70% power. After it shut down the light that was on the charger turned to a faint orange blinking light and now is a faint green blinking light. This is the first time this has happened. I can't get the power to come back on. Need help asap!

Macbook Pro 2007 Random shuts off

I start having issues with my Macbook pro it's randomly shuts off, sometimes in 5 minutes, 30 minutes , 3 hours or even before it will boot to the os.
It's getting really hot and fast without doing anything, any help??

My macbook started with the monitor going black but the light was still on. Now it will randomly shuts off and a light blue screen pops up saying my computer shut down due to a problem. Then reboots. This happens sometimes 5 times a day, sometimes none. I thought it had something to do with using video because it tended to happen when i was watching video. Now I just move my computer on my lap and there it went.
I took it to the genius bar - they ran tests, etc. and found nothing (after 5 days). The guy was extremely rude and not helpful at all. After my IT guy and myself went to the Apple store, they gave us a hard time saying they couldn't replicate the error. So after a few seconds, the man changed his mind and said he was going to change my logic board.
$600 later (luckily still under warranty) - my computer shut down again tonight.
Not a clue what the problem is. I had 90% battery life. I have noticed that recently I've been putting my copmuter to sleep before I close it.
Anyway that could be it?
