Mac stuck in startup

I was recently grounded by my parents, so I had to give up all of my electronics. When I handed over the Mac, I wasn't aware that it was in sleep mode. So it was firmly locked away for a month in sleep mode which I'm sure is very bad. So I got it back today, and as soon as I turned it on I had to update Itunes and Adobe Flashplayer. A tab came up, stating that I needed to restart my computer. I restarted it with no trouble, but I thought that it would be a good idea to let my mac rest for a couple minutes before I started using it again. So I shut it down, but when I tried to turn it back on there was only a grey screen with the Apple symbol and a loading wheel below it.
When I go to Disk Utility, I can not repair the hardrive. Instead, a tab comes up saying that I must backup as many files as I can, re-format the disk, and then restore the backed-up files. How do I do those things and what could have caused this?

It will not go into Safemode, and resetting PRAM and NVRAM results in the unchanging grey screen although I do hear the second chime. When I put it into verbose mode, the last thing the terminal reads is:

'kernel is LP64 [I0BluetoothHCIController : :setConfigState] calling registerService'

I went to the recovery hardrive, but could not install Lion, since the hardrives were locked. I don't have a backup in TimeMachine. My laptop is a 13" OS X MacBook Pro Lion.

Are you talking of this screen?



If yes that should be totally normal...


[…]When I go to Disk Utility, I can not repair the hardrive.[…]
  • The operating system partition cannot be repaired unless you are booting from the recovery partition. However you may repair the permissions
  • How do you get into Disk Utility if you are not able to boot? Did you try using the recovery partition?

I have never heard of this tab/window… does this appear when you start your mac and wait? is it possible you could make a picture of it and post it?


Maybe it is worth a try to use the Safe-Mode… just to check if it would boot (Booting in Safemode usually takes a few minutes longer than normal boot)


Is your hard-drive encrypted by Filevault 2

I am aware that that is completely normal, however the loading screen has stayed that way for about four hours with no completion.

I went to the recovery hardrive by pressing 'ctrl+r' at the startup. I had the option of using Time Machine, which I can not since I ahve no back-ups. I had the option of installing Lion, which I can not because the hardrives are locked. I had the option of seeking online help from the help section on the Apple website, but it hasn't been too helpful. I lastly had the option of using Disk Utility to verify the permissions, and to repair the disk but I can not. A tab came up saying that the disk could not be repaired and that I needed to back-up as many files as I could, re-format the disk, and then restore the backed-up files.

I already tried to get into Safe-Mode but my laptop remained with that very same grey screen as you pictured above. I know that it takes longer to load, but I had the laptop on for a couple hours and nothing popped up. Should I have just left it on over-night while it was loading?

Ehm, I don't know... I don't know what Filevault2 is. I'm sorry.

Can you boot into Single User Mode? (Command + S) If you can, it should arrive at a CLI prompt. Type:

Code:
/sbin/fsck -y
/sbin/mount -wu /
reboot

No, it just goes to verbose mode. I can't type anything, I just see qhite writing on the black screen.

The white text on a black screen is single user mode(assuming you used Cmd+S to get there). It should arrive at a prompt where you can type. Then put in the commands from my previous post. That is called a CLI(Command Line Interface), as opposed to a GUI(Graphic User Interface). Those commands do a filesystem check(and repair if necessary), mount the filesystem cleanly, and then reboot, so that the filesystem unmounts cleanly so if that's the only issue it should reboot into a working system.

No, there is nothing that comes up that allows me to type. I've pressed cmd+s before I turned the laptop on and after but I'm never able to type in anything.

Maybe disk is dead (I had similar problem with macbook air revA) - but AFAIR i was able to format disk and instal os x (but after max few months, same thing happened again) - try to boot from usb drive, does that work?

Maybe you could try the Target Disk Mode

Oh - sorry to hear that nothing worked so far…

Do you have another computer available?

If yes:
You might be able to try to retrieve/rescue data of your computer by using the Target Disk Mode (Depending on your MacBook Pro it would be via Thunderbolt or Firewire)

  • when booting press 'T' before the Apple-Logo shows up
  • e.g. a firewire symbol should appear instead of the Apple-logo
  • connect the mac via Firewire/Thunderbolt to another computer
  • your mac should show up like an external hard-drive

About FileVault 2

*FileVault 2 is an hard-drive encryption technology developed to protect sensitive information. It encrypts the entire hard-drive. Disk utility can only repair such hard drives / partitions if it knows the password to decrypt the hard drive. But it doesn't look like that this is the case with your Mac.
