Macbook Pro freezing at "grey apple screen". Please help!

by azure82 / May 20, 2013 1:53 PM PDT

Hey there. My Macbook Pro running Lion (2011 I think) just started flipping out, freezing at the grey Apple screen and going no farther into the boot process, no matter how long I wait.

I've tried booting in "Verbose Mode," and it stops short with this message every time:

" efiboot loaded from device: Acpi (PNP0A03,0) /Pci (1FI2) / SATA (0,0) /HD (Part 2, Sig00005765-1E06-0000-FE55-0000C7010000)
boot file path: \System\Library\CoreServices\boot.efi
..Loading kernal cache file 'System\Library\Cached\com.apple.kext.caches\Startup\kernelcache' ...
...................................
root device uuid is 'AEA287EA-B11D-3CD0-97A5-D925B8612DBD' "

I tried booting into the "Recovery Drive" and nothing different happens. Grey Apple screen forever.

I tried booting in "Safe Mode" and.... nothing. Grey Apple screen.

I tried booting in "Single User Mode" and enter commands in the LINUX command line. It doesn't allow me to type anything.

I also did the reset thing where you hear the "startup sound" 3 times. This did reset the system settings for sound and mouse tracking speed, but did not help the situation.

I DO have everything backed up in cloud storage online. I DO NOT have an OS recovery disk. Bought the laptop used without one.

You guys are my last hope before taking this baby to a Mac Tech and laying out serious cash. Thank you to anyone who has sage advice!

ps. Didn't know how to attach a screen shot, so I transcribed the screen message. If you know how, please enlighten me!

Without any disc to attempt to boot this thing from

you have just about covered everything that might be suggested here.

The next step would be to boot from an external OS X source to see if the problem is software or hardware related.
Disk Warrior or Tech Tool Pro both come with a version of OS X built in. Not free but not exceptionally expensive either. In order of preference, (mine of course) DW then TTP

Unless you can lay your hands on one of those, then the Mac Tech is your next stop.

FYI, that "Linux" command line is actually a UNIX command line.

Your advice to check out DiskWarrior is well received, thank you very much. I looked at the website. It looks like it's priority it "saving your data." I don't think my data is at risk since it's all backed up online, but I am concerned about my hard drive. Will DiskWarrior fix my hard drive if it's fixable? thanks again for the advice!

Anyone else that has wise advice, please chime in? Thanks Happy

"saving your data" but I think you are looking at it from the wrong angle.

DW rebuilds disk directories. Without those directories your computer does not boot because the system cannot find what it is looking for.
Usually this means that the user has lost all the data that was on the drive, at least until the directories are repaired.
Just because you have all your data backed up off site, does not mean that DW is not for you.

If you believe that, then why not just go out and purchase a new hard drive and install it?

You either want the drive repaired or not and if repairing the drive enables you to access the data on it, then DW has done its job

I have no reason to disagree with your case, thank you for your helpful advice! Do you know if DW can be used on any version of OSX? Say, 3 years from now on OS 10.10, would it still be able to work, or is it more of a required upgrade type of software? If you know this off hand, thank you

who respond to any changes that Apple makes to the booting procedure of their machines.

Point upgrades are usually free but Mark upgrades are usually fee based. (Just like OS X)

To work its magic, DW has to be able to boot the computer and when Apple changes the way a Mac boots, then the version of OS X on the DW disc will not boot the changed machine. However, if you have an external drive with a version of OS X that will boot your computer, then you can install DW on that and run it from there.

I cannot guarantee that DW will work on all the future versions of OS X, then again, you cannot guarantee that all your current programs will work on them either.
