@KROLL41 - sorry for the out of topic.....
try booting on safe mode, maybe you can fix your issues that way or at least know what's wrong. I am however, with Clinton on this one about your hard drive might be failing.
Good luck and hope you sort it out...
Cheers...

Try Resetting your Mac's PRAM and NVRAM
If that doesn't help, try Resetting the System Management Controller (SMC)
If neither helped, boot from your install disc, run Disk Utillity. The startup disk may need repairing.
Using Disk Utility to verify or repair disks
Check the S.M.A.R.T. status at the bottom of the Disk Utility window.
Make sure it says: Verified

Macbook pro a1150 wont boot past kernel, stuck on gray screen.

got a macbook pro a1150 ati 1600 gpu. last for characters in sn are vww. will not boot past gray screen after the gray screen with the apple logo. it has a fresh install of 10.6 on a new hard drive from a laptop of the same exact kind. when in target mode and its Hard Drive used as a boot divice, it will boot. no broken graphic on startup with the apple icon and the pin wheel spinning. boots to safe mode just fine, will even do updates. but will not boot from the NEW hard drive or the dvd rom. when i put the old hard drive in with 10.5 it wont boot past the blue screen and the same with the 10.5 install disc i baught. reset pram, changed ram, removed wifi card and even tried disconnecting the dvd rom but still will not go to the login screen. even disabled auto login (when it was in target mode). do i reflow the gpu? is it a gpu problem? one thing strange.... in safe mode, lines show up on the mouse icon and just that. the rest of the screen shows everything fine, i've seen this before with the nvidia chipset but not with ati. how do i fix it?

to better explain... the macbook pro in question never get to the blue startup screen which happenes before the login menu. not though dvd rom, hard drive, external dvd rom or external hard drive. just stop there. i hear the hard drive working / dvd spinning and the computer reading the disc but after a few min of just seeing the grey screen both would spin down.

My macbook air 11 inch wont boot up. it is fully charge. it was working last year. what happen

help please

What happens when it tried to boot? Is there any screen display? If there is but it won't boot from the internal SSD, then I'd boot from the USB key and try to repair the SSD. If that doesn't work then I'd try to reinstall the OS.
If you are not getting any display any display I'd consider taking it to a local Apple Store to be looked at. It would still be under warranty.

Macbook pro (retina) wont boot - can't get to recovery

I'm having a bizarre problem with my Macbook pro retina 15".
I was using bootcamp/booted into windows and playing Star wars the old republic when the machine suddenly froze, then the display started going into lots of squares of multiple colours.
When I try to boot in to OSX it freezes after the apple logo and the small cirle stops. If I try get to the recovery by pressing cmd + r the same thing happens. I've also tried using the internet recovery option, the same thing happens after it connects to my wifi etc.
If I press alt during bootup to get to the different drives to boot from, the icons (i.e. OSX or bootcamp) are displayed but are slightly brown and look a bit distorted. If I select bootcamp and try to boot into windows the squares/distorted screen issue starts again.
I have also tried booting from a mountain lion install usb i made - same probelm as above: freezes after apple logo.
I've also tried resetting the PRAM/NVRAM or whatever its called.
Does anyone have any ideas I can try as I can't call Apple care til Monday now?
Thanks

Nope. Your only option is to take it to an Apple Genius Bar as your system is FUBAR. More then likely a hardware problem from over heating.

Macbook pro 17" wont boot up

Greetings,
I left my macbook working on my desk , when i came back back the computer was in sleep mode, the computer woke up but the screen did not turn on, however i could hear the sounds of OS X when i clicked on the volume keys but no video. after holding the power button for 7 seconds the computer turned off. when i tried restarting the computer the sleep light would light up and remain solid, but it would not boot.
Took the ram out and the sleep light blinks 3 times, but when i put the ram back again but it goes back to the solid sleep light with out doing nothing
some steps i took
-battery is fully charged and it charges the battery
-unable to do a pram
-took off battery and disconnected form wall and hold the Power button for 8 second
i would also note that this machine had the logic board replaced due to the nvidia 8600gt recall.
Thank you in advance
-Illankid

well i took my mac to an apple authorized service center, the tech told me that computer does not boot up and thus they are not able to perform the "nvidia test" which mean that the laptop does not fall under the recall. so im stuck on ordering a new logic board on my dime.ill update on my decision.i am missing it.

Macbook 27" monitor wont boot OS X problem?

My macbook hasn't been connected to the internet for a while and it was working fine today until I connected it to wifi, as soon as I did that it shut off. I tried turning it on and a get a grey screen with a colorful wheel with a pop up that says "The OS X installation could not be complete" and then the computer shuts off. I cannot click the options that the pop up has available either. Any idea's on how to fix this?

It would seem from the dialog message you got that the computer had been in the process of updating OS X. In any case I would suggest that's exactly what you do. What version of OS X is installed on it?
Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU 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 DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstall Lion, Mountain Lion, or Mavericks without erasing 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.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- 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.

Macbook pro 2011 wont boot

Hi,
I need a help regarding issues with my macbook pro. I am getting bluescreen on start up. Here is a link: https://www.youtube.com/watch?v=lzryrh5x-Rs
I did new reinstall of mountain lion but it was working for about 10min, after I did first update, I did restart but it just stopped at grey screen.
I went also to apple shop, they did tests and said that all HW tests are ok and it should be something software related.
What could be causing this issues? Could be logic bord regarding all HW tests?
Interesting thing is that when it is doing recovery it can be powered whole night with no problems.
A also did pram reset but no luck.
Tnx
Miha
Macbook pro, late 2011, 2.2 i7

Run these steps first. I see you reinstalled. Run the other troubleshooting options, particularly in the second article.
If you see a blue screen at startup - Support - Apple
Mac OS X: Gray screen appears during startup - Support - Apple
If it persists, run the Apple hardware test. It could be your logicboard ...specifically thinking your discrete GPU since this has been such a big issue for these models.
Using Apple Hardware Test - Support - Apple
Message was edited by: nbar Completely misread the OP. I see hardware diagnostics checked out. Can you boot into SAFE MODE without trouble?

Macbook Pro 2012 wont boot

While i was using my Macbook all of a sudden it shutdown when i connected a usb to it. It was/is charged to 98/100%. The charger is shockproof and after the shutdown the light at the end of the charger is very faint. Any advice? I wanna avoid opening it but apple is not an option in my country.

Macbook pro retina wont boot

A week old laptop refuses to boot have tried everything availiable online still no luck!
Are apple skiming on quality?

Many thanks, will try and get it replaced if lucky as get back to London on the 13th of January as presently in Kenya. Was happy with my original bought last year which has worked flwlessly so picked another for my daughter, however having it die in less than ten days is a pain as gave it to her as a Christmas present.
What is the procedure when you book a genius appointment?
Are they supposed to get it working while you wait?
If they cant manage this do they replace the same machine?
Any advice is highly appreciated.
Thanks in advance

MacBook Pro: Tiger wont boot past grey apple screen w/ spinning gear, HELP!

Hey everybody,
I have a 1.83 Ghz MBP with 512 mb of RAM (lame I know). The other day someone was using my computer to burn a CD on iTunes when all of my programs began failing. On instinct I rebooted my computer to solve the problem. Alas, now I cant boot past the grey apple screen, and the gear is spinning away. Saddest part of the story is that I had time set aside to back up my computer the day after this happened . Anyway what is the best thing to do from here? I haven't made any moves to fix it yet really, so what is the best thing that I can do to try and get my files back?
Thank you,
Sam A.

Hi, I posted to you in yoour other thread.
I very much doubt Disk Utility or fsck will fix an +Invalid Node Structure+ error. That's a pretty serious error and DU is just not robust enough of a utility to repair it.
If Disk Utility can't fix it, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy. Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.
I use DW once a month to try and catch errors in my system from getting too far out of hand.
If you have a good backup, hopefully a clone of your system before you had issues, an Erase and Install will also rid you of this issue. But, beware! You will lose everything on the drive with this procedure. Let us know if you need help with that!
Cheers! DALE
p.s. If the +Invalid Node Structure+ is real bad, there's a risk even the mighty DiskWarrior will not be able to help. Normally it will come thru; it's only in the severe cases it won't be able to do it. If you don't have a backup, and need the data bad, it's worth the try!

My Macbook Pro 2011 wont boot properly. only when batter is disconnected. HELP

hi all.
i have recently bought a macbook pro, 2011 i5 4GB knowing it wasn't fully working, but i need some help.
when i try and power it on, nothing happens at all (it did turn on once for about 10 seconds, then shut itself down.) i have since been playing around with it, fault finding, and i have found out that if i have the battery disconnected, and have it connected to the charger it works! (if holding CMD+D.) i have tried running the hardwear test, but when holding down the relivent keys on startup it just continues to load the OS X as normal. i do not have the start up discs either. im not entirely sure where to go from here, id love to know what could possibly be causing this fault. any help would be greatly appreciated. thanks in advance.

Update - I've got it all powered up, updated etc. it only doesn't start now after a forced shutdown (holding off button) if I press shutdown, restart etc it works fine. Really want this sorted, any help would be greatly appreciated. I'm ripping my hair out! Thanks

My macbook pro currently wont boot, when i turn it on it leads me to internet recovery and after that to the utilities pannel, when i tried to reinstall ox lion it didnt show any disk what do i do?

someone help me plz thanks.

The internal drive has failed.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Brand new Macbook pro 15inch (not Retina) wont boot my MBP 13 inch (2011) HD

Just bought a brand new macbook pro 15 inch, replaced the hdd with my 13 inch hdd and it wont boot. i got a Error msg. (Lion)
- I put the new hdd in the old MBP(13 inch) and it boots fine.
- I put back the old hdd in the MBP(13 inch) and it boots fine.
I figured the hdd wasnt compatable with the 15inch so then i cloned the 13inch hdd onto the 15inch hoping it would work. i still got the error msg.
so now im stuck because the 15inch wont boot from the stock hdd because it has the data from the 13inch. Very frustrating, what could be the logical reason to why it wont boot?

That's correct. The version of Lion you have on your old disk will not boot on the new machine.
What you should have done is make a Time Machine backup of your old drive. You still may be able to buy an enclosure for it and see if you can use Migration Assistant to migrate your apps and data, but I'm not sure that will work (works when an old drive is in another Mac and you transfer via, for instance, Firewire).
So you'll just have to resinatll the correct version of Mountain Lion and then you can TRY to use Migration Asistant to get your data/apps from your old hard drive once it's in an enclosure (again, I'm not sure that it will actually WORK, I've never tried it).
