Boot in safe mode fails

Since installing iTunes 11.1 on iMac and iOS 7 on iPhone 5 and iPad 3 the computer has crashed with increasing frequency. Verified hard drive and no problems reported. Now I can't even boot in safe mode - it fails half way through - grey progress bar disappears, then cog disappears and am left with white screen. Any suggestions?

Boot into recovery mode (CMD+R), launch Disk Utility, repair the disk and its permissions. If that doesn't do the trick, reinstall the OS and rerun Software Update.

Internal disk not recognized, booting in safe mode fails too.

My computer was fine, randomly froze, so I held down the power till it shut down.
Since then I only get the grey screen when I try to start Mac OS up on the internal drive. I tried to repair the internal drive or start from it using the installation CD, but it doesn't recognize my internal HD drive anywhere. When there's no disk and I have the grey screen, the computer also makes a small, "booop, click, click, click" sound. Don't know if that helps but that's what I've got.
I've also tried starting the computer in safe mode. That fails and tells me something about the disk being immediately dependent on something. If it helps I can do it again and try to write it down.
Any help would be great thanks.

Hi AveryBazan & welcome to discussions...
Some or all of the following may be necessary - try in this order:
1. Try resetting your PRAM/NVRAM ( http://support.apple.com/kb/HT1379?viewlocale=en_US ). If everything isn't fixed, then continue to follow the steps here including resetting your SMC ( http://support.apple.com/kb/HT1411 ) if necessary.
2. Use Font Book to eliminate all bad and duplicate fonts.
3. Reinstall (or install for the first time) the .6.1 and .6.2 updates by downloading and installing the combo updater ( http://support.apple.com/kb/DL959 ).
4. Reinstall 10.6 using your Snow Leopard install DVD by installing Snow over Snow using the upgrade method. Test your system after returning to 10.6. If is good there, then you may not want to re-install the.6.1 & .6.2 updates - if you do, then use the combo updater again ( http://support.apple.com/kb/DL959 ).
Still no joy, take it to an Apple Store and ask staff there for assistance.

How can I transfer files from a 27" iMac which will only boot in safe mode?

My late 2009 27" imac is having issues and will only boot in safe mode. I have tried to transfer files to a new Imac using migration assistant but it wont let me. If I try booting the old Imac normally I just get a grey screen, I believe it is the video card failed and am waiting for a fix, but I would like to transfer files before the fix in case something goes wrong and I lose everything.
Any help would be great

Hello Myles, likely it is a Hardware problem.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Won't boot in safe mode

Hi,
I can't get my PowerBook to boot in safe mode. I hold the shift key after the startup chime, then release it when I see the gray apple and progress spinner; but the spinner spins for a while and eventually the computer shuts off. I can boot up normally, but I'm trying to boot in safe mode to rectify a problem I have updating Office 2004. I tried zapping the PRAM, but that didn't make a difference.
Thanks,
Michael

Well, according to DiskWarrior my news isn't good: "DiskWarrior has successfully built a new directory for the disk named “Macintosh HD.” The new directory cannot replace the original directory because of a disk malfunction. A disk malfunction is a failure of or damage to any mechanical component of the disk device, or any component connected to it."
So I suppose my HD is on its way out, although it's not exhibiting much in the way of problems yet, and the S.M.A.R.T. status is still verified. And, rather interestingly, I can no longer use Disk Utility to Verify or Repair disk when I'm booted up from an external drive. I get this message:
Repairing disk failed with error Could not unmount disk
Which just seems weird, since this is the same way I'm running DiskWarrior.
I love this PowerBook but I'm not sure I want to invest the time or expense in replacing the HD in a PowerPC-based machine. I assume new apps will soon be demanding more than that chip can handle. Does this message of doom from DiskWarrior generally reliably indicate the drive is beyond repair?
Thanks, Carolyn, and to anyone who wants to chime in.

My 27" imac won't boot in normal mode. The screen stays white. I have upgraded to Yosemite. However, the computer does boot in safe mode. Could this be a virus related issue or possibly a video card issue?

My 27" iMac will not boot in normal mode. The screen stays white. The computer will boot in safe mode. Could this be virus related or is it possibly an issue with my video card. Before this happened, my computer screen was flashing weird things and the computer would unexpectedly power down.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter

10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line

to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.

First MBP Grey Screen/Boot Problems/Only boots in Safe Mode

Hi everyone,
I've spent the last few days researching previous troubleshoots and threads on the subject, but haven't had much luck unfortunately.
This is a 2011 MBP, 2.2 GHz, 4 gb RAM, 15 inch. As a preface, I use(d) an external monitor via my MBP's mini-display port, and at some points, the monitor (both) would become distorted, vertical lines running down, and then both would freeze, so I immediately thought my GPU was going. Then after a few restarts after the problem occurred a few times, I got the infamous boot issue: the grey screen (after viewing the spinning logo), so to the forums and research it was.
Now, my MBP will boot in safe mode with no issues. Getting it to boot off of a disc with the "C" option works about 50/50, but I usually end up being able to get to it.
This is what I've attempted thus far from everything I've read:
Repaired Disk: repaired
Repaired Permissions: repaired (both of which I did in safe-mode AND from disc-booting, if that helps)
Reset SMC
Reset PRAM
Reinstalled factory RAM (2 x 2 gbs) ((I had a 2 gb stick and an 8 gb stick) Status of RAM via Profiler: OK
Removed peripheral devices to give that a shot with no luck
Reinstalled OS X (Snow Leopard, by the way, from disc)
Performed both abridged AND extended Apple Hardware Test: No problems found (which is what took me away from Logic Board or GPU issues..)
Used Time Machine backups to restore from previous working date (I regularly backed up my MBP) and have two seperate external drives with backups, though no clones.
Reformatted my entire 750 gb HD, last night, reinstalled the OS X, did not try and restore from Time Machine (as I know I could do that at a later date) and following completion of the OS X install and upon the "restart" requested of me, my MBP had a dark blue freeze, so I cold booted to the same problem of the grey screen, which is where I'm at now.
Summary:
Can Safe Boot with no issues. Reformatted drive. Reinstalled OS X (10.6.7, software update to 10.6.8). Operating with original RAM, went through trouble shoot procedures.
From what I've read, a lot of people have said to replace the MBP Hard Drive cable (SATA) cable, which I have ordered per my model, so I'm waiting on that.
Is there anything else I can do, or try in the meantime? I'd like to know peoples' thoughts on if my HD has failed (thought DU says it's fine) and the fact I can boot in safe mode, and whether a hard drive cable replacement is a probable fix.
This MBP was purchased NEW in June of 2011 and has been well maintained.
Thanks for any thoughts, suggestions, critiques,...anything.

Lion 10.7 Only Boots in Safe Mode. Is This a Hardware or Software Issue?

Hi. On my iMac late 2009 i7 8GB bought last March only. I reinstalled Lion (I didn't erase the whole disk because I have Boot Camp Windows and I have filed there) and it can only boot in safe mode if I use the Mac's built-in EFI bootloader (where you have to press option on restart) menu then press shift after choosing the iMac OS X hardisk. I've been trying to fix it for around 4 days now today. I'm tempted to take it to the authorized Mac shop but that could take weeks to months in our country. If I let it boot normally, it would seem to have a kernel panic and would stop at the white/gray screen. Verbose mode showed that is stopped at something 10 of these like: nstat fail.
Is this a GPU hardware problem, specifically the 3D element of this 4850M GPU? I'd like to do load each kext, each extension manually but I can't find them in Lion. When I use the Lion DVD or the Lion Recovery partition, it's very sluggish, every click and process takes 20 seconds to minutes. If I try to boot in Linux, Snow Leopard DVD or Snow Leopard external hardisk, there seems to be a kernel panic. It's either just a black screen or a garbled screen.
I want to erase/format the iMac's hardisk but in Safe Mode, it can't be mounted even if I use Disk Utility. If only there's a way to force it to mount, I can save some Windows 7 file to one of my external hardisk or flash drive. Does anyone know of an app or program that can mount NTFS files on Lion's Safe mode?
If it's a Lion bug, has Lion somehow corrupted the Mac's built-in (hardware not the EFI partition in the hardisk) EFI or somehow corrupted the Mac or GPU's ROM? Could it be a new OS X virus? Should I then perform in Safe Mode to flash the GPU ROM and the Mac's ROM again (I have the latest)?
Do you think if I erased the whole drive, reinstalled it again with either Snow Leopard (assuming it doesn't boot into a garbled screen) or Lion things will go back to normal?
Has anyone experienced something like this? What was the culprit (was it a hardware or software issue) and what was the solution?
Gbu.

Hi thanks for all the concern and replies. I've tried all that.
I had just got it back from the shop last Friday. It was there for around two weeks. It was a faulty GPU (when you see garbled display that's consisten when booting it the GPU). I have a strong feeling it's related to the Lion install 10.7 or 10.7.1 and may be similar to reports of Mac laptops overheating. It's good the GPU is removable, it might have taken 3 week or a month if it had been the whole board.
It's a blessing in disguise though as with all or most cases because I also got to have the LCD replaced for excessive backlight bleeding (in my opinion), the dead pixel from the previous LCD isn't there anymore (though under the glass there're some smudges but nothing crucial). The backlight bleeding is still the same though in my opinion but at least it's new.
It's a great thing I bought Applecare. I didn't buy it for the iPhone because that's more durable (my iPhone 3G's 3 years old now and it's still solid. Although there are scratches and a crack at the back at the bottom, got sqeezed under the table I think when I sat). I think Applecare is a good recommend for things that get hot like desktop and laptop Macs(are the iOS considered Macs btw?) which are twice or thrice the price of iOS devices.

Can't boot into safe mode or prompt login window, need help.

Hello all,
This is cross-posted from the installations and set-up list.
Can anyone suggest a remedy for what's ailing this powerbook. its a g4 powerbook, i don't have much more info other than that. all indications are that it is running 10.2.6, although i was told that it had been updated to 10.2.8, its possible that it was updated only to 10.2.6. following the update, you get to the apple and spinning pinwheel screen and it will not proceed. literally, the pinwheel will spin for 24 hours+.
it looks like it gets to the point of the startup(login) items and hangs indefinitely. ie it will
if i start in verbose mode it will, give some clues:
truncated or malformed library: /System/Libray/Frameworks/Security.frameworks/Versions/A/Security
Some starup items failed to launch due to conflicts
/usr/libexec/crashreporterd: crashdump terminated by signal 5
init: getty repeating too quickly on port /dev/console, sleeping
/usr/libexec/crashreporterd: crashdump terminated by signal 5
last message repeated 10 times
/usr/libexec/crashreporterd: crashdump terminated by signal 5
init: getty repeating too quickly on port /dev/console, sleeping
/usr/libexec/crashreporterd: crashdump terminated by signal 5
last message repeated 5 times
this will continue to be repeated and i assume a new core.## file is sent to the /cores folder, until the hard drive is maxed out.
I can boot in single user mode and everything is fine but i cannot boot into safe mode.
fsck says the disk is fine, as does disk first aid, i have also corrected permissions, and followed many of the things that have been previously posted.
It looks like ther are conflicts with some startup items, what can i move from the starup folder and is best not to be touched?
what about the truncated library message?
also can i update to 10.2.8 from the single user mode, if i cannot get into safe mode?
any suggestions?
thanks in advance-
todd

I have solved this problem. I mounted the laptop in target mode and replaced this file:
/System/Library/Frameworks/Security.framework/Versions/A/Security
with the equivalent file from a machine running 10.2.8.
It booted all the way through then i upgraded to 10.2.8.

Won't boot into safe mode

My 2012 iMac 27" was randomly rebooting itself, while in Sleep. I assumed this was due to the cheap 32 GB memory I bought, but before I could change it back to the original memory, to test, the Mac booted into Safe Mode (I assume - a progress bar showing at the bottom of the boot screen, below the Apple logo), and did not get further than a half the way, and then shut down. I swapped the memory to the original 8GB. I tried booting again, no buttons held down, as then it wouldn't get further than a quarter of the way. Further attempts to boot do not work, even when holding down Option to choose the boot disk, pressing Shift for Safe Mode, or Option-S for Single User Mode. I assume it's trying to boot in Safe Mode, but failing?
I also tried using a good Mac with the bad Mac as the Target Disk boot mode - the good Mac does not see the bad Mac...
I have an external DVD drive, but that isn't an option as I can't go into boot drive select mode. What are my options, apart from sending the iMac back?

Booting into the Recovery HD should allow you to effect repairs - that's the point of it, so it's a bit concerning that it won't allow you to. The Recovery HD is a partition on the internal drive that should allow you to effect repairs to the Macintosh HD, albeit part of the same physical disk.
I'm no expert, but I'd be concerned that the hard disk is on the way out. Do you have backup of everything - Time Machine or a bootable clone, perhaps?
Maybe have another try with Command+r. If it fails I'm not sure what would be the best next step - it depends if you have a full and up-to-date backup of your disk so that you can restore.
One of the options of the Recovery HD is to allow you to re-install the OS, which won't delete your data.
The more extreme step would be Internet Recovery which would involve erasing everything and re-installing via the internet.
Worth reading this carefully before proceeding: http://support.apple.com/kb/HT4718
Disk Warrior from Alsoft (not cheap) is another possibility for recovering damaged disks, although it's not a guaranteed solution.

Intel Mini will only boot into safe mode - hangs on ANY Mac OS volume

I have an Intel Mac Mini... the core2duo 1.83GHz or whatever.
I acquired it from it's previous owner, as it was "broken".
He could not get it to run an install disc.
It will not boot any of the Mac OS install media (DVD or CD - 10.4, 10.5, 10.6).
It will not boot/install a Linux disc (I haven't tried, but that's what I was told).
It WILL boot/install Windows !?!?
So... anyway, I removed the HDD, and installed OS 10.6 Leopard on it (FW Target mode installs kept failing at the end - regular retail DVD). I then reinstalled the HDD back into the machine.
The system keeps hanging at the same point it would when trying to boot an install DVD - after the screen turns blue, it goes back to the gray screen, then immediately freezes.
However, I eventually discovered that it WILL boot into safe mode !
Everyone kept saying it's the logic board failure, but if it boots into safe mode, can that be true ? It doesn't seem to me that it would be hardware based in that case - unless it's just a specific component, like the Airport module or something.
The last line displayed in Verbose mode when it hangs is:
"athset_txchainmask[5124] sc->sc.config.txchainmask 5 mask 5"
It also says something about the Airport just before that.
I tried removing the Airport module and it still hangs.
I also tried different RAM, with the same results.
I ran the 10.6.2 combo update in Safe Mode. It still hangs. Haven't tried 10.6.3 yet, though I do have it downloaded and ready to install.
This thing is driving me crazy. Please tell me there's a fix, OTHER than replacing the logic board ?!?! It just doesn't seem like it should be so complicated considering that it runs in safe mode.
It's rare I can't figure out a Mac problem - please help !

Very strange, and getting stranger !
Ok... so, from safe boot mode, I installed Windows XP Pro using the boot camp assistant.
Everything installed perfectly. I started up from Windows, and put in the Mac Mini recovery disc, in order to load the drivers. The Boot Camp software started with Auto Run, and I clicked through to install everything. The drivers start loading...Windows reacts positively, with the system tray announcing "new hardware installed" every 30 seconds or so. Airport/WiFi IS working (in Windows), as it detected my router/network...this is where it gets F'ed up - when the installer gets through with the drivers, and installs the boot camp software for Windows - the system reboots, goes through the usual Windows startup...the desktop background appears, but no icons or start menu - then it reboots again...same thing, again, over and over in a loop.
Went back into OS X (safe boot mode). Installed reEFIt (a bootloader utility), to see if maybe I can bypass the Mac OS/Boot Camp bootloader. No luck. Install worked, but still had the same issues.
For the heck of it, I try installing Linux Mint 8. The live CD starts up OK, but only as far as the boot menu. I tried the installer first - after the splash screen, it hangs on a plain gray screen (w/o the normal linux installer language selection menu - just solid grey).
I tried running the live CD w/o the installer - the actual OS. Same thing - after the splash screen, it hangs, only it's a black screen this time. If I use verbose mode, it still seems to hang on the WiFi card.
Here's the strangest thing yet - Ok, remember, it wouldn't boot normally into ANY Mac OS volume - including the installer DVDs - only in safe boot mode...
So, I try the "hackintosh" IPC osX86 10.5.6 DVD - it boots into the installer with NO problem, WITHOUT safe boot mode ! I tried installing it unsuccessfully. I forget now which options I choose, if any, though I may try it again later and pretend it's just a non-apple PC with the same specs as the Mini (or try just the "base system", and the bootloader - then run the official Apple updates)
This last thing really makes me think it has something to do with the EFI/bios - however, I've only been able to find info on how to update it, not replace or restore it - and it's only from a working install, not forced from a flash drive or CD (plus when I do try the installer from safe boot mode, it says it's current and unneeded).
I still haven't changed the hard drive. After almost successfully installing Windows, I made the assumption the -hardware- was OK, and reassembled everything.
Currently, I'm trying a direct installation of Windows XP Pro SP2 with which I'll try installing the drivers WITHOUT the boot camp software, to see if the WiFi (Airport card) and everything else is indeed working OK (remember too that the system passed ALL the ASD 3S116 tests).
So anyway, that's the current status. Any new ideas anyone ?
Thanks.

Can Only Boot in Safe Mode

Suddenly, I'm only able to boot in safe mode. If I try to boot or reboot normally, I hang at Apple screen.
Prior to the first failed reboot, I was unable to use system update because it kept hanging and I had to force-quit it (which was my reason for rebooting). Prior to that I had (what I thought was) a completed successful install of several updates requiring reboot (the last several items, except for Safari 4).
Any thoughts on what might be going on here (a messed up system update still in progress, perhaps) and what I might do to fix it (some system update state files I can delete)?
Any help is appreciated!

Login screen comes up repeatedly, booting into safe mode by default

Good Morning,
I have an iMac (Lion 10.8) that is having a lot of trouble. I manage an Elementary School's IT fleet. At the end of last year, the computer was booting into Safe Mode by default. Once the system came up, the teacher could use it - but it took so long to boot that she chose not to. The teacher left the school, and I was planning to just format it and reimage. Here is what I have happening.
Boots into safe mode on it's own
Once it's done booting, the login screen shows up - but entering any credentials just gets a grey screen, and the login screen comes right back. Even root. Which means I can't get logged into the computer at all.
Recovery mode will not allow me to erase the drive, says failed and not able to access the drive.
Target mode will also not allow me to erase the drive, nor will it allow me to push over an image. Scanning the drive failed, busy.
Disk repair says unable to repair disk - please format.
These are the things I have tried.
Reset PRAM (three times over the course of troubleshooting)
Replaced the RAM completely
Unplugged 15 seconds trick
Accessing via Target mode - Drive is greyed out, but shows up
Ran FSCK manually, and it completed
Tried to do a netinstall, but the disk does not show up in netboot as an option.
I thought maybe the drive was bad, but considering that it will boot into safe mode eventually (although you can't login), and FSCK completed successfully - I'm just not sure! I just thought I'd pick your brains. I'm usually a Windows \ Linux Administrator, so this Apple business is new to me I'm learning! Although I find them frustrating. Any help would be greatly appreciated!
Thank you

I thought maybe the drive was bad, but considering that it will boot into safe mode eventually (although you can't login),
Some part of the disk may be bad while others are good. i/o could be trying multiple times and eventually succeeding.
Ran FSCK manually, and it completed
You run FSCK in single user mode? This is very surprising. FSCK verifies the filesystem is in order. Actual data blocks could be bad. Would be a surprise if no file system blocks were not also bad.
Except for this fact, it seems like a hd problem. Intermediate problem. Heat problem, etc.
Time to try a different hd. See if that works. Could be some other hardware problem. Try external drive/flash drive, etc.

Mac Pro won't boot into safe mode

I tried to boot into safe mode by using the keyboard key and the progress bar got a little bit of the way across but then it got stuck and sat there for 2 days with no change. Any idea why no safe mode? Here's a photo of the screen how it sat for 2 days:
https://dl.dropbox.com/u/23232804/no%20safe%20mode.JPG

Here's the few lines right around the boot attempt: at 1pm on 12/31 I tried to boot into Safe mode, then seeing that it was taking forever, I left, and came back on 1/2. It was in exactly the same spot so I rebooted normally. Does this give any clues?

My Macbook Pro began crashing when I tried running safari. An error message came up asking that I repair the HD volume. Before I was able to run repair, computer shut down. Now I can not get it to boot. I tried booting in safe mode to no avail. Pls help.

Can someone please help me with a Macbook Pro booting question?
Recently, my mid 2010 MacBook Pro has started acting up when I am on Safari. Safari would unexpectedly crash multiple times in a row, then run fine for a while, then again, crash repeatedly. Not long after this began happening, an error message from my Prosoft Drive Genius 3 software, threw out a message that a serious error had occurred and I needed to repair the HD volume. Before I was able to run the software to repair the HD volume, the machine stopped working. I turned off the Macbook and when I tried to restart, it would not boot. I have since removed all external hardware from my machine and tried several times, unsuccessfully, to boot. I have also tried booting in safe mode when also does not work.
Any suggestions? Thanks for your help.

Try SMC reset:
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. (four keys together)
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
