Need urgent help! Mac OS X won't start up. Disk Utility can't find harddisk

I started up my computer today, and instead of booting into Mac OS X, the screen shows a folder with a question mark on it. I can startup my machine using my Panther disks that i've got, but when I go to disk utility, it can't find my hard disk. Looks like the hard disk is not mounting at all.
If i try to install Mac OS X, that also doesn't give me a hard disk to install it on..
I really need help on this because I was supposed to get work done today.
Would diskwarrior sort this problem out?
Cheers

Hi, Ken.
Start with the troubleshooting steps outlined in "Mac OS X: Your Mac won't start up."
If you're running Tiger (your profile does not indicate what version of Mac OS X you are using) and you only have the Panther install discs, do not use Disk Utility from the Panther discs on your startup disk. See "Only use Mac OS X 10.4-compatible disk utilities with Mac OS X 10.4 volumes."
I recommend you have someone at home send you all the discs you should have with you (Apple Hardware Test, Tiger Install Discs, Software Restore and Install discs, etc.) for your eMac by overnight courier, e.g. FedEx.
When you recover from this problem, it's also time to consider investing in a comprehensive Backup and Recovery solution. For advice on the backup and recovery solution I employ, see my "Backup and Recovery" FAQ.
Good luck!

Macbook w/ whole slew of problems...Won't Start Up, Disk Utility Can't Repair Disk, Horizontal Lines on Screen, Etc.

I purchased my Macbook in the summer of 2011 and before it went berserk it was running Mavericks. 3 years later, it's finally seemed to have run its course.
It won't start up normally and it won't start up on safe boot. Attempting to use disk utility to repair the disk only gives me the message: "Disk utility can't repair this disk. Back up as many of your files as possible." There are also horizontal lines across the start screen (before it inevitably shuts down) and the screen looks very faintly purple-ish/off-colored.
This actually didn't come out of the blue. On Monday, my macbook suddenly froze, went white, and beeped three beeps repeatedly. I restarted it and backed up all my important work files and set up an appointment at the genius bar for Friday once work ended. It remained buggy during this process with the beeps returning an occasionally a blue screen popping up.
Unfortunately, there wasn't enough space to back up my important photos and by the time I returned on the next day with an external hard drive to store them on, my macbook would no longer turn on.
Is there anything I can do to bring my macbook back to life? Ideally I'd like for it to last one more year before I graduate college. Is it still salvageable, and if so, is it worth salvaging?

I hate to spread gloom, but that computer has serious problems. The only people who can diagnose the problem(s) are technicians. I would take it back to the Apple store for further testing.

Help! PB G4 won't boot and Disk Utility can't fix it!

I have an insufficiently backed up PowerBook G4 1.67MHz (1GB RAM) that suddenly nosedived last night. I was surfing the Web and OmniWeb froze up. I couldn't force-quit it because the Finder was also locked up. So I held the power button until it shut down. When I restarted it, it got to the grey apple screen and hung there. I booted off the Tiger CD and ran Disk Utility, but it couldn't fix it. Then I tried booting into single-user mode and it also failed. Finally I tried reinstalling the system, but the CD couldn't find the hard drive. Aaargh!
I have a bunch of documents that I really cannot lose, and the most updated versions of them are only on this drive. Anyone know any tricks or third-party utilities that can help? I have another Mac; would Firewire Target Mode or Network booting help?
Some details:
Here's what Disk Utility said:
Invalid volume header (this was written in red)
Checking Catalog file
Keys out of order (in red)
Rebuilding Catalog B-tree (in green)
The volume [name] could not be repaired (in red)
Error: The underlying task reported failure on exit (in bold red)
1 HFS volume checked
1 volume could not be repaired because of an error (in bold red)
Repair attempted on one volume (in bold)
1 volume could not be repaired (in bold red)
Then it popped up a dialog box:
First Aid Failed
Disk Utility stopped repairing [name] because the following error was encountered:
The underlying task reported failure on exit (in bold)
Here's what single-user said:
It all booted normally, then I got these ominous entries in the list:
disk0s3: I/O error.
jnl: dojnlio: strategy err 0x5
jnl: open: could not read 512 bytes for the journal header.
hfs: late jnl init: failed to open/create the journal (retval 8).
nfs_boot: networking is not initialized
panic(cpu 0 caller 0x001F2634): nfsbootinit failed with 6
[then there's two backtraces here]
panic: We are hanging here...
PowerBook G4 Mac OS X (10.4.8)

As Mr Peck advised, DW is your best chance of getting out of this.
The important point of your post is the hard shut down (were you running Classic?) and the mention of Keys Out of Order. Do a search on these boards for Keys Out of Order for a quick education of the problem.
Make sure of the version of DW you use, get the disk and don't download, and make sure of your firmware version.

OMG freaking out please help!! Installer won't install..Disk Utility gone?

Newer mac user here with very little osx experience. First post on the forums really hoping you can help.
I have a couple issues right now. First of all, lately when I try to install apps nothing happens. More specifically, when I click on the .pkg file nothing happens. The screen kind of flashes (it doesn't really flash, but I don't know how else to describe it) like it wants to do something, but then.....nothing. This has happened recently with both a divx codec I downloaded from divx.com and also with neooffice. I have tried dumping the neooffice download in the trash and redownloading and trying to reinstall and it does the same thing everytime.....nothing.
Second....can someone tell me exactly what is supposed to be in the applications/utility folder? I thought there was a disk utility program in there that would allow me to reset permissions, but I can't find it!! I can't find it using finder either!! I am freaking out a little bit here and any help will be GREATLY appreciated.
Thank you for your help in advance!

Sounds like you trashed a few things from your Utilities folder. For details on restoring one or more missing pieces, see my post at:

HELP! 2nd Hard drive keeps disappearing. Disk Utility can't see it either!

I'm hoping 1 of you experts can help me out with a very annoying problem.
November 17th I purchased a new hard drive for my Mac, Deskstar P7K500 500GB.
I checked on 2nd Chance PC if it was compatable etc, and this was the reccommendation for the size I wanted.
*For your info my Mac specs are:*
Machine Name: Power Mac G5
Machine Model: PowerMac9,1
CPU Type: PowerPC G5 (3.0)
CPU Speed: 1.8 GHz
L2 Cache (per CPU): 512 KB
Memory: 4 GB
Bus Speed: 600 MHz
Boot ROM Version: 5.2.2f1
After installation I wanted to use Disk Utility to format it. It didn't see anything at all.
After an hour or so of PRAM reboots and anything else I could find online it appeared. I formatted it and all seemed well.
However last Monday, whenever I double clicked on the drive it seemed to take awhile before it opened. By yesterday afternoon I was getting the spinning wheel whenever I tried opening it.
So I decided to run Disk Utility on it to see if it needed permissions repaired. It didn't show up there at all. So I restarted and it disappeared from the desktop.
System Profiler saw it, but the text was corrupted, the words were gobbledygook in the drive description. So I figured I'd check with Disk Utility again. Still wasn't there. After rebooting it had completely disappeared from System Profiler all together.
So since Sunday I have been trawling forums and Apple help for suggestions. I've tried most things apart from messing with the Terminal stuff because I figured I'd mess that up LOL.
Are there any tricks you know I can try?
Or should I just send it back to Dabs as a faulty product?
Could it be my Mac? I can't send it to Apple as I bought it from a Apple reseller 2nd hand and didn't buy additional Apple Care.
I have data on it which is unfortunate but not life threatening as it was a new drive I backed up elsewhere also.
Thanks
BigSteve

Hi-
"OEM" would be Original Equipment Manufacturer, which means the drive would have firmware specifically aimed at PC/Windows users.
The description of the drive specifiactions only states "PC" in compatibility, so I would assume the drive to be OEM, though not stated specifically.
The drive should work with the Mac, though it could be a firmware version problem, or, simply a problem with the drive. The Hitachi 7K drives are generally well regarded by Mac users.
In the past, any reported problems were either a firmware problem (typically early release models) or simply a bum drive.
BTW, the Hitachi site states that all their drives have the necessary Mac drivers in the firmware (along with the Windows drivers).
A test, would be to swap the drives in your Mac. Put #1 in #2 bay, and #2 in #1 bay. If the problem with "seeing" the drive stays with a particular bay, the Mac may be at fault. If the drive doesn't show regardless of bay, I would suspect the drive.

Need Urgent Help! iPhone 3Gs won't detect SIM after update to ios 6.1.3

So yesterday me and my sister's phone was working fine. I decided to update both of them, and when I updated, everything was reset to factory settings. Everything is running smoothly, but our phones won't detect the SIM. Either it says "No Service" or "Invalid SIM" when I turn on Airplane Mode. Urgent, please help!

I performed a backup / full reset / erase all / restore. When the phone rebooted, it appeared to be a clean, new iPhone (unnamed, no apps, no wallpaper, etc). I restored my backup and the notification is still there. I tried doing a hard reboot (home+off buttons), still there. I will attempt one more reset / erase / restore.

How do I repair a damaged dmg that won't mount and Dick Utility can't repair?

Apple Care gave me wrong instructions on how to create a disc image of my internal HD then erased it. Now I have a .dmg that has the same gigs as the HD but won't mount and Disk Utility can't repair. Tried to recover files with Data Rescue 3 but that isn't going so hot. Any suggestions?
Thank you

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
I guess that it's a moot point to ask if you didn't test the dmg before you erased the drive. Do you have a Time Machine or other type of backup?
If not, it's a hard lesson to learn, but I would guess that unless you are willing to pay for expensive outside data recovery service, all is lost and you are starting over.

I am new to mac air. Today i installed (unsuccessfully!) MAPLE16 on my mac book air. Now since it does not work properly (it also does not appear in applications) i decide to delete it. I could not remove it from launchpad . i need urgent help

Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmyrmac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button.
You generally have to reboot in order to complete an uninstallation.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
You may be advised by others to try to remove complex system modifications by hunting for files by name, or by running "utilities" that purport to remove software. I don't give such advice. Those tactics often will not work and maymake the problem worse.

Need Urgent help, I have made partition hard drive in my mac book and using OS mac

Need Urgent help, I have made partition hard drive in my mac book and using OS mac & Window8 seperately... for couple of days it works great for both window & OS mac But nowadays, my pc gets restart automatically while using window & even I cant access to my Mac OS........... I got some error in window (error80070003) ...>>>>> Now how can I format whole drive & recover my Mac book OS.without boot disk.

I can't find that model. If you open System Profiler in the Utilities folder look for the Model Identifier over in the right hand display. What do you find for the model ID? If your computer supports Internet Recovery here's what to do:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer. If Mavericks is not installed, then you can reinstall it by re-downloading the Mavericks installer.
You will need to use Boot Camp Assistant in order to create a new Windows partition, then reinstall Windows.

Do you have a Time Machine backup or clone? If not,
all is lost if you have in fact deleted your OSX partition
and you will have to do a reinstall from Recovery HD
and install all else.

I need urgent help to remove unwanted adware from my iMac. Help!

I need urgent help to remove unwanted adware from my iMac. I have somehow got green underline in text ads, pop up ads that come in from the sides of the screen and ads that pop up selling similar products all over the page wherever I go. Its getting worse and I have researched and researched to no avail. I am really hestitant to download any software to remove whatever it is that is causing this problem. I have removed and reinstalled chrome. I have cleared Chrome and Safari cookies. Checked extensions, there are none to remove. I need to find an answer on how to get rid of these ads. Help please!

You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
Back up all data.
Triple-click anywhere in the line below on this page to select it:
/Library/Application Support/VSearch
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchAgents/com.vsearch.agent.plist
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
Restart and empty the Trash. Don't try to empty the Trash until you have restarted.
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. It must be said that this failure of oversight is inexcusable and has seriously compromised the value of Gatekeeper and the Developer ID program. You cannot rely on Gatekeeper alone to protect you from harmful software.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Have you ever done a hard factory reset of your Airport Express base? If not, then try it. Push down the reset button with a pen, then keep it depressed as you plug AX into the wall and keep holding it down until the green light blinks 4 times and then turns amber. Then let go. Unplug your broadband modem for a couple of minutes and shut down your Mac. First restart the modem, then the Mac. Use Airport Setup Assistant to set up a new network from scratch.
In System Prefs > Network > Show > Network Port Configurations drop n drag Airport to the top of the list and deselect all port configurations that you do not use.
That's a start.
