Start off with a flashing question mark appears when you start your Mac and then if you are still getting no where, run the Apple Hardware Test.

I tried booting from Apple orignal PB CD. Same as above
I tried to install Tiger X from original CD.It wouldnt.
please help.I have valuable data on my HD.

Try things in Apple doc.#106464 for your startup issue.
Also, try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption. Smokes link will help walk you thru it.

Macbook pro froze during partition. after force shut down it, a part of hard drive lost

2011 15' Macbook Pro with Mountain Lion.
I was trying to use Bootcamp to install windows. Somehow I got confused and used disk utility to partition my hard drive and get 100gb for windows (before that it was 500 gb with 260gb free). And after 10 minutes the computer froze and I could do nothing but force shut down it. Rebooted and disk utility shows that it has 160 gb free space now. I repaired disk and permissions but none of them worked.
How can I get my 100 gb back? Help pls
Thanks

Check this link and see it any info will help.

Keep getting a grey screen with circle with slash at start up after force shutting down

My MacBook is fairly new (purchased in August 2012) and today it was running fine and began freezing... When this has happened in the past I have just force shut downed it, and it started up normally. This time around when I went to start it up I got the apple logo on a grey screen followed by a circle with a horizontal slash (like a do not enter sign).... tried to safe boot it and I got another grey screen but now with a folder icon. Please help!!!

Whoooo - if you have no backups (what were you thinking?) then hang on if you can and some wise soul may come across and give us a solution.
What you need to do is to repair your drive from an external. What happens when you do a 'Command+R' upon restart after the chime?
I also clicked on the stuff on the right and it is really dated! But current Mavericks' users will surely come along and address the issue. Until it is solved, please don't erase the installation, since you do not have a backup!

After forced shut down iosx does not accept the password on the mcbook air

Hi there,
I cannot login into the mcbook air after having to force a shut down.
- While surfing with Safari, the mcbook froze for a longer period of time.
- We forced the shut down pressing the on/off button.
- After rebooting, we have a grayish screen with the apple logo, the user name, the password field and in the bottom three options: idle mode (rest), restart & shut down.
- When the password is entered, the wheel shortly turns and the mcbook stays with the same login screen without letting me enter the mcbook.
- When using an incorrect password the password-field shakes.
I tried booting with CMD + R and did check the volume and the access rights. Both showed no failures.
What could I try next to fix the problem? Ideally without having to set up the mcbook from scratch and losing the settings and data.
I do not know the exact IOSX status. It was bought in Nov-2012 and updated once since then I assume it is Snow Leopard
Thank you for your help!

If you can boot into the Recovery Volume, it isn't Snow Leopard.

After forces shut down,restart returns to you tube with no screen

The screen of my Mac book pro has gone black. The key board is lit up and the sound is good. After restarting it, the same you tube site was still on as before I shut it down.

Welcome to the Apple Support Communities
If you are using Lion or Mountain Lion, it automatically starts all the applications that you had opened when you turned off your Mac

After having shut down after installing updates, when I restarted and tried to open a word file, it started opening ALL the word docs and the only way I could stop it was by"force quit" arted and tried to open

After having shut down after installing updates, when I restarted and tried to open a word doc, it started opening ALL the word docs and the only way I could stop it was by"force quit" . This is REALLY annoying!!

May be it is the Resume feature.
System Preference > General > Number of recent items
Uncheck the box next to "Restore windows when quitting and re-opening apps".
Best.

I tried to reload my Ipod touch. I accidently selected "start new ipod" icon on the Ipod and then "back up existing ipod" on Itunes. Now the Ipod is unresponsive, constantly shutting down and restarting. Even after multiple "forced" shut downs. Help!

After updating the os, I tried to shut down, clear and reload my Ipod touch. Here's where I goofed: at the prompt for starting the reload process, I selected "start as new Ipod" on the Ipod, but in Itunes, I selected " back up existing Ipod from computer" or something like that. Now the ipod is constantly shutting down and restarting and no controls can be accessed. All I can do is the "forced shut down" which I have done multiple times and let sit for a half hour off.

Disregard, hooked up to itunes and clicked on summary, selected restore, all is well.

Recovering files after a force shut down

**** all,
My mbp froze up last night and I had to do a forced shut down. When I rebooted all was fine except for a pages document that was open during the freeze was lost. Can this file be recovered?
Thanks,
Brian

I don't know if Pages periodically saves to a temp file, but if it does, that temp file should be in a Recovered Files folder in your trash can. If it's not there, or if you emptied your trash and got rid of that Recovered Files folder, then you're out of luck. Any unsaved changes are gone.

My Macbook Retina doesn't log back in from sleep after typing in the password, have to force shut down

Hi all,
Recently i've been having this problem once in a while (once every few days) that when I opened up my computer from sleep, I typed in my password and clicked enter. After that, it shows that normal grey box thing; normally it logs in after a few seconds, but sometimes i wait for 2 minutes and still it doesn't log in. I sleep it and wake it again, but this time i type the password and i click enter, but nothing happens, i can't click switch user either. At this point my only choice is to force shut down my macbook. This problem is a bit annoying since sometimes i have unsaved work.
Thanks in advance for any reply/ies.

Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Waking from sleep requires Forced Shut Down on two different g4 iBooks

Two different iBooks, a 12" 1.33 and a 14" 1.42 . Same behaviour on both iBooks.
Each is running 10.4.4, Each has 1g RAM. Neither have any unusual third party software or hacks. Both exhibited this behaviour prior to 10.4.4, and both had 10.4.2 as the original install, then 10.4.3.
Both go to sleep after three hours, display is set not to turn off before then. They will operate properly for days at a time, but approximately once or twice per week they will have gone to sleep normally, the white light blinking. I'll tap the keyboard to wake up, and the white light will stop blinking but nothing else happens. The cd drives don't make their usual start up racket, nor does the hard drive or fan spin up. Only doing a "Forced Shut Down" by holding down the power button and then restarting will bring either one of them back to life.
I have already Reset the PMU several times over the past 6 months with no change in behaviour. I have also reset the PRAM on both units sucesfully, however that also has not changed the behaviour.
Were this happening on only one iBook, I'd consider it a fluke, but having it happen on both a 12" and a 14", and having read of the others with the same isssue leads me to believe that it is not a unique issue, and is either a hardware or software flaw. Since the advice in every one of these complaints has been rest the PMU and Reset the PRAM, and since this has failed to correct the situation, I'm curious as to whether there is anyone on thes Forums that has knowledge of the problem and a proper fix.
As the issue is truly random and can not be duplicated on demand by manually putting the machine to sleep the "geniuses" have as yet not provided a solution. All I would like is an acknowledgement that there is an issue and that there is hopefully a fix in the works. Even just an acknowledgement that, "it sometimes happens" would be helpful.
Sorry for the long rant, but I keep seeing the same issue brought up over and over again, with the same non-solutions. Any other suggestions or clues would be very much appreciated.
ibook G4 1.33ghz 12, 1.42ghz 14 Mac OS X (10.4.4)

Nothing, No one..... So out of the hundreds of thousands or perhaps millions, of iBooks sold in the past year, I somehow managed to snag the only 2 that display this problem. Those odds are staggering. A 12" 1.3G4 and a 14" 1.42G4, purchased two months apart. Both in the original factory state, and they both display the same sleep issue, and yet somehow this is unique to my experience.
The sarcasm is intended, and after having to do a forced restart, and then wasting an hour running tech tools to make sure there are no disk issues for the third time this week, this is getting old. I'm not asking anyone for a magical fix, all I'd like is confirmation that the issue is being investigated and will hopefully, eventually be resolved.
Thank you......

Persistent USB Arch installation fails to boot after first shut down

Hey all,
I've recently installed Arch on a 32-GB USB flash drive (with the help of the wiki, of course). I have some experience installing arch on my computers, so the process went relatively smoothly. As some background info, I AM using UUIDs in both the bootloader and the fstab file, so that shouldn't be a problem.
Anyways, the problem itself: I have arch installed and ready to go, and it boots up fine (the first time). The thing is, after I shut down, if I try to boot the USB drive again, it simply hangs there-- no boot. What's weirder is not only does it not boot, but it also freezes the host computer at that point in the boot cycle. I mean, everything will be frozen up at the startup BIOS/splash whatever screen when the USB key is in, but once I take it out the computer will boot up regularly. It's really strange.
If I reinstall the bootloader on the USB drive then everything works again (that is, until I reboot).
Is the bootloader somehow getting corrupted while shutting down? I have tried using both GRUB and SYSLINUX (not at the same time of course) but they both behave the same.
Any help would be greatly appreciated.
Thank you for your time,
Ushahin

Here you need to set the right hooks if the root is on a USB drive, if you use RAID, LVM, or if /usr is on a separate partition.
Did you remember to do this?
If not, mount the partition(s) starting with the root partition first, chroot into it, edit that file and re-generate the initramfs. Then reboot with the reboot command, don't forcefully shut it down using the power button or something like that.
It could also be a BIOS issue. Restore its defaults, set "Removable Dev." first, "CD-ROM" second (if you have an optical drive), "Internal Storage" third. Then select the USB stick as the first to boot in the boot priority screen.

My Computer has been freezing all of a sudden in the last week and i have to keep doing force shut downs!!!

My dad usually helps me fix this stuff, well go figure he is on vacation and a day after he leaves, the computer starts giving me problems. im so angry with it right now i might throw it off my balcony...
The loading icon randomly starts spinning sometimes and wont stop, requiring me to do force shut downs in order to make the computer usable again. sometimes it does it right away, sometimes it does it after ive been using the computer for a bit... for a while i can switch windows until it completely freezes. i cant click anything, cant force quit any programs or anything, and i the spinning beachball never goes away! the computer isn't hot either when it crashes! SO FRUSTRATING! it was perfectly fine until the last week or so. im anything but a computer genious, but i ran the disc utility and it says the drives are fine. things ive done in the last week. done the updates that the app store was pestering me with, updated corel painter 12 with the most current patches because that started randomly crashing. well now painter works and its the computer crashing X.x
I dont have extensions on my safari aside from adblock. and i only have 2 apps downloaded and corel painter is the only software on the mac side of the computer. parallels has an adobe suite on it but Corel is the only thing that has gone through changes recently...
i dont know what to do... i need to work on projects and the computer keeps making me lose progress and keeps giving me frustration. please help if you can...
I've never used the forums before so i don't know the right category, but if its wrong im sorry. if you can just move it into the right one...

Back up all data immediately, if you haven't already done it.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ 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 Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

Since upgrading to Mavericks I have to force shut down to close frozen applications

Hi all,
Since upgrading to Mavericks I have experienced several times that sometimes when an application close a simple force quit is not enough. The application will disappear from my dock but remain on screen with the spinning ball, and any instances of the application I try to open will also freeze instantly. The only way to clear them is to do a force shut down via the power button on the back of my computer. I have experienced this with Mail, VLC and Finder so I do not think this an issue with a specific program. If anyone is having the same problem or has an idea of how to fix it, it would be much appreciated

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Portege M300 hangs after "Windows shuts down" comes up on the screen

The computer hangs after "Windows shuts down" comes up on the screen. The same happens in hibernation mode. I have to turn off the computer by holding the on/off button.
I have updated my bios, installed all windows updates that are available and done a numer of other things. It startd just out of the blue. Any ideas?

Hi
Does it happen after the OS installation from the Toshiba recovery CD???
Did you install any further programs???
I have noticed a similar freezing on my notebook. Mostly it happened because the background process did not close and therefore the notebook could not force the shut down. In my case it was a adobe acrobat reader which could not close.
I think you should defragment you HDD and use the CCleaner freeware application.
This program cleans program errors and corrects the registry entries.
Try it! Maybe its not a serious issue!
