Macbook sudden shutdown during startup.

I have an old macbook 2008 aluminum. It has mavericks installed and worked fine with it until now. It only starts up to the apple logo with the standard circular loading icon below and abruptly shuts down, same thing happens when booting to recovery. I have also tried booting into a usb mavericks installer which is what I used to install Mavericks cleanly but also my macbook also exhibited the same behavior, It shuts down suddenly a few seconds after the apple logo shows up. Inadvertently if i stay on the startup menu by pressing the option key and stayed there the macbook doesn't shut down abruptly. I have tried the so called "quick fixes" e.g reset smc etc. but none of them worked. Same thing happens when I try to boot into safe mode.

It sounds like you have tried all the altenatives I would have tried, and then some. It is time to take it to an Apple store for a free diagnosis and estimate for repairs. The good news is the data on the disk is probably OK so if your Mac is caput you can extract that drive and put it in an external enclosure.

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. Depending on what install method you chose, any problems you had with 10.5 could be transferred the the new install. You may not have realized you even had any.
Then Repair Permissions.

Most likely.
You can try to boot from the Install DVD for your Mac and run AHT from there if it boots.
If not it sounds like it is time to take it to Apple for repair.

Macbook pro stalls during startup

My macbook pro with Yosemite stalls during startup. I've tried Command R and ran disk utility. The disk is ok. I've zapped the RAM but it still stalls about 25% of the way through the startup process.

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

MacBook Shuts down during startup

My MacBook started acting slow the other day and then today when I started it up, it was in a constant lock up with a spinning pin wheel. No force quit commands or anything would work. So, I restarted it and now after the Grey screen with the Apple logo, the MacBook shuts down. The only thing I can get running is by holding C with the Leopard disc in there.
I tried to run Disk Utility from there but everything failed. I'm assuming I need a new hard drive? Is there anyway to save data from within the Leopard disc bootup? Maybe over a network?
Thanks

Hello,
I am having this very same issue. It shuts down during startup. I can boot into Windows, and using the Leopard startup disc, Disk Utility could not work any magic. I do not have a second Mac or access to one for any backup purposes. I have no idea what else to try, does anyone know something besides backing up through firewire, on how I can either save my computer's data or resurrect the drive? Thank you for your help.

Macbook pro freezes during startup after Yosemite

hello, i have a Macbook Pro (Retina, 15in, early 2013). I have since used it and never had any problems. i am also running the latest version of parallels (which i just updated before downloading & installing the update from Mavericks to Yosemite. Since installing Yosemite, i was able to use my macbook for about a day...suddenly during a login attempt i kept gettting the spinning wheel & the computer would just freeze.. ive been reading this comments & questions for the last 3 days & tried as much as i am capable of. I can not get the computer to boot in safe mode... i CAN boot it holding commandR...but than at that point i ran disc utility and it said no errors... I am utterly lost....this macbook doesnt come with a built in CD/DVD drive and i have NO CLUE how to properly back up anything...i DO NOT KNOW WHAT TO DO...can someone PLEASE help me using as much LAYMANS terms as possible? I truly appreciate ANY HELP!!! thank you in advance

... and i have no idea what else to do :?
Return that RAM and buy either the Crucial ram (http://www.crucial.com) for your system or buy from OWC (http://www.macsales.com). I've used Cruical ram in many systems over the years with no issues, and have bought Samsung (factory fill) from OWC with no issues either.

I am having a sudden shutdown during start up

During the initial start up of my MacPro i am having a sudden shut down looks that the power has just been turned off. After trying again the same thing happens.
Basically at the moment i cant start up the MacPro to see what is the problem.
Does anyone have any ideas?

The way to deal with it, assuming that the disk is indeed getting full - Get Info on the disk in Finder and see how much space it says it has - is to first see if you've emptied the Trash. If not, do so and see how much space that frees up.
If that doesn't help the issue, then you'll have to remove documents. What documents you can remove is something only you can answer. There may be applications you've installed that you can remove, or movies that you don't need or can archive off to another disk, etc. A utility such as WhatSize or DaisyDisk can help you determine what's taking up all your storage space.
Regards.

My MacBook keeps freezing during startup

I got my MacBook Pro in 2012. Currently, it keeps freezing while I try to turn it on. I get the apple logo and the spinning wheel, and eventually it freezes. I've tried starting in safe mode and it froze. I've tried recovery, it "restarts due to a problem during start up" and then freezes again. When it freezes, there are little green pixels on the screen as well.
Any help is appreciated! Thanks!

My MacBook Air chimes during startup but flashes a bar at the bottom then shuts down, is this a hard drive failure or a hard ware failure? Please help I miss my laptop

First generation MacBook Air running OSX 10.6.8

Hi,
From what you describe it's certainly a Hard Drive failure so you'll definetely need to contact HP. Personally, considering this is the 2nd HDD in under 2 months, I say it's either bad luck ( however unlikely ) or there is another issue at play - it may be worth suggesting this to HP when you contact them.

MacBook suddenly shutdown after opening anything that something that got to do with Flash

Happened today,
I was rendering a video last night and I let my MacBook stay all night with brightness +0
So, I wake up this morning realizing that my MacBook was sleeping and the battery was on 0%
Okay, so here's my problem..
Ive plugged in my magsafe and recharge my MacBook as it should be.
Then when I opened something Flash, eg; Youtube, *The video gets laggy than couple of minutes later.. It shut down unexpectedly without any animation or stuffs just "pop" with black screen*. Okay then I let it cool down, opened it again and this time I'm not watching video on Youtube, so I thought it has been something wrong with Youtube so I avoided youtube. So I was surfing on facebook and played this one vid on facebook.. Then the *...* problem happened again. So I am guessing this out that is has to be done with the Flash Player or stuff that control the Flash thing. OR it has to be done with the fan or something.
Hope you guys can help!
Zofran.
Macbook Late 07, Core 2 Duo 2.16GHZ, Black, Running on Snow Leopard [10.6.8]

Buy a replacement.

MacBook beeps once during startup, then loads up normally.

I have had this problem for about five days already. My Macbook 5.1 (late 2008) boots up and makes one 3 second long beep sound, then it starts up normally after. It is very annoying, as I use it in uni and other public places, and it makes this sound. I have tried changing my ram to the old one 2 x 1gb, and back to 2 x 2gb, it didn't help. I have searched all websites for this answer, but didn't get any answers to this problem
Please help, as I am doing alot of work on it now, and if there is a problem with it, I really need to know it.
Anton

Yeah, that time they gave me a replacement MacBook Pro 13 inch, very good service. Now I have trouble with my new retina macbook pro, there are dead pixels on the screen.

MacBook shuts off during startup

I have a macbook I got in 08 that is running leopard. Ok so after running Onyx it told me that the volume needed to be repaired. I inserted the install disk and ran disk utility and the volume repair, but it told me it couldn't be fixed. So I quit out of all that and restarted my laptop, but now it won't get past the blue loading screen. The little wheel just goes and goes then my MacBook shuts off. I can still run the Mac os x installer. When i go again to disk utility I can see the Macintosh hd tab and before I couldn't. Is this a good sign?
Can anybody please help? Should i just try to do a restore, if it would let me or?? This is my first time dealing with a problem with a mac and I don't even know where to start.

Thanks for responding. Yes, I have used time machine, although I stopped it from backing up data about a year ago (big mistake). I was wondering if it would be best to restore with time machine or do a restore and then connect the external hd to get my data manually. Because have I changed my login name from the last backup and I don't know if that would cause any extra problems. I really don't want to lose anymore data.
I was also wondering how to go about using diskwarrior. Is it a separate disk? Because right now I don't know how I would get the install disk to eject from the laptop.

HT1237 My MacBook Pro freezes during startup. It shut itself down a few days ago and won't restart since then.

Forgot to mention, downloading a firmware update is not possible unless one has another way of starting the machine. (I'm posting this on my iPad.)

Computer shuts down during startup

Hey everyone,
it shames me a little to ask for help about computers because I am usually ok with doing this stuff myself.
This time, however, I cannot seem to fix the problem indefinitely.I need a laptop for school and cannot afford another so any help would be greatly appreciated!:
I will just point the facts out:
After a few years use (two) it now shuts down during (windows) startup.
I ended up cleaning the Heatsink/fan yet the problem persisted.
The model is a Toshiba Satellite A200-PSAF6A.
I am no longer under warranty.
The school techs cannot help me.
A few oddities that I noticed:
It starts up fine when the power plug isn't plugged in.
It starts up fine with the power plugged in only in safe mode.
Using CCleaner and Defraggler temporarily fixed my problem (for about 5 minutes or so).
I hope that you guys can help me. It's just annoying that I cannot fix this myself..
If any further information is required please just ask and I will reply with as much haste as I can under my current circumstances.
Thanks,
Norak.

During a "cold start" I may get up to the windows login screen and then it shuts down and restarts. (sometimes it doesn't make it to the windows screen and turns off to restart). Then it will start to load windows and the little bar at the bottom will be loading windows and then freeze. I would have to hold the power button down to turn off and restart. Then I start windows normally and it usually works OK, sometimes I have to do this step again, but eventually I get into windows. Then if I shut down and restart it starts up fine, unless I wait for it to cool down.
Since this started happening, I have reinstalled vista 32bit to out of the box condition and updated to the latest bios, to no avail.
Computer has always run hot since new, seems to have very poor cooling. But the fan operates, most of the time on full boar.
Do you think this is a software issue or a component issue, or cold joint.
BTW it will not shutdown at all if I keep the computer in the F12 key settings area,im not sure what this place is called, but you choose to boot from cd here.
Okay, this is weird and I'm not sure if this has anything to do with what I had mentioned earlier. I was having some issues with my DVD drive, it was rattling bad and the spin off time was off causing coasters on almost every blank DVD, so I had the thing sent in for a replacement. They put in a new DVD drive, checked the status of my BIOS (V 4.2 which I had all along) and returned the unit back to me sometime around April 22, 2010 -- ever since the thing was working fine. I'm not sure if the bad drive had caused the unit to work erratically.
Before it was sent in, the issue was of course with the DVD drive, the startup then shutdown problems, plus a whole plethora of other small problems which I didn't bother to mention on my first post. For instance; the illumination lights that controls the media -- sometimes they would not turn off when I shut my computer down. The light stays on even after the computer powers off and I'd have to unplug the AC power cord for the lights to completely shut off.
My initial problems with the laptop was:
Media lights won't go off,
DVD drive rattles very loudly and burns bad media,
Shutdowns during startups,
The screen housing would creak every time when I wanted to adjust the position (this happens when I adjust it slowly).
After they replaced the DVD drive, everything seems to work fine. It's been almost two months now and I haven't had issues with any of the above mentioned problems.

Firefox crashes during startup

Hi,
My Firefox (v18.0b7 version) needed for specific web application accesses) suddenly crashes during startup.
I've tried remove/install again, same behaviour. creating new profile changes nothing.
Crash id : bp-880858a9-1110-4907-939b-a33e22141114
Could you help?
Thanks,
Thomas

OK, apparently something has been broken with my Software Center. Version 28.0 is pretty old, after all.
So I just launched Update Manager and updated everything to 14.04.1.
Now Firefox runs and displays 32.0 in its "About" dialog.
