IMac won't boot (late 2009) Please help!
I have a late 2009 iMac that I leave on 24/7. I haven't used it in a couple of days, and when I went to use it this morning, something major is wrong. Firstly, my mouse would not wake it up, which wasn't a big concern. I pressed a button on the keyboard and it woke up. I could see my desktop with a message "Time Machine could not backup" or something like that. There was a also a spinning circle and nothing was responsive. So I long-pressed my power button and shut down the computer.
When I powered back on, the Apple logo appeared, but also a gray bar underneath it that began to fill up. The bar seemed to fill up, but then the computer just shut down again. I tried this one more and it did the same thing. So I don't think it's going to boot up.
I booted into recovery by holding Option when starting the comptuer, and then went into Recovery (not my Time Machine, just normal Recovery). I started Disk Manager and I can see all of my drives. My main 1TB drive (internal on my Mac) showed the main drive and then Macintosh HD, which was not mounted. I also saw my Time Machine external drive that was also not mounted. I attempted to Repair my Macintosh HD disk, but it said it could not be repaired. Uh oh, I don't think this is good.
Then I tried to Verify my external drive that has the Time Machine on it. It said it needed to be repaired. I clicked on Repair and it is currently in the process of repairing. It said it checked the file system, volume repair complete, and now it has been on "Updating boot support partitions for the volume as required." for several minutes now with no sign of progression. I don't know if it's going to complete or not, but I'm leaving it alone for now.
SOOO.... I'm trying to understand what happened? I assume my main Macintosh HD drive failed, either during a Time Machine backup, or perhaps it tried to backup to Time Machine when it started failing? I don't know because like I said, I haven't used the iMac for several days, so I'm not sure when it happened or how long it's been. However, if my Time Machine drive is failing too, that doesn't make sense, does it, unless it got corrupted when the main drive failed?
I need advice on how to proceeed? If the Time Machine drive succesfully repairs, then I will try to boot from that, right? If it does not repair, then what do I do? I believe I have most of my data backed up on Crashplan, but not everything... and if both of the drives failed or corrupted, am I just out of luck?
I appreciate any help...
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed.

Computer won't boot up! Please help.
How's it going guys, I have a powerbook G4 that I have owned for a few years now. I woke up this morning to my computer making a weird processor noise, it was a repetitive noise, and my screen was frozen. I thought my computer had frozen or something. I did a hard shut down on my laptop and my computer will not boot up mac osx. It stays Stuck on the Apple page. I've tried taking the battery out, i've tried new ram, and i've tried restarting it several times, and to no avail has my computer booted back up. I have the mac osx disc and that won't even load up. Can anyone please help me out. I'm in dying need of my laptop! Thanks! - Brian
When I try and repair the disk it reads the 74.5 GB TOSHIBA MK8025GAS Harddrive but It doesn't read the HD drive right under it. I click on the toshiba disk and i tried repairing it and it gave me an error message. The message reads : "First Aid Failed. Disk utility stopped repairing HD because the following error was encountered. The underlying task reported failure exit."
The actual disk utility window reads "Invalid node structure" in red letters. "The volume HD could not be repaired : Error : The underlying task reported failure on exit. 1 HFS volume checked : 1 volume could not be repaired because of an error. Repair attempted on volume 1, 1 volume could not be repaired.
Any suggestions? And how do i go about doing an archive install? And how do i go about using diskwarrior? Thanks guys. I really appreciate this. I need this computer up and running for school. I'm actually at my college library typing this out. - Brian -
Arch 8.0 won't boot after upgrade :((( please help
OK guys, I've been running Arch for almost a year - switched from Ubuntu. The problem is that after a large update (around 520MB) I did a couple of days ago I can't boot into my system.

I can only access the command line through the single mode.
If I won't get any help I will be forced to wipe everything out and do a fresh install. Please help.
I can provide you with other log files - just give me their exact localisation.
PS. I don't have access to the internet after I log in through the single mode. Lots of errors...eh.

Well I'm not sure how exactly I managed to fix it, but I'll write it down for the people that may experience similar problems in the future.
I logged into my Linux using the 'single user mode' - by adding the 'single' word at the end of the kernel line in GRUB.
I gave myself write permissions by issuing the command 'mount -no remount, rw /'.
I removed the gensplash-initscripts, then installed normal initscripts, then installed gensplash-initscripts again and modified the rc.conf file.
Rebooted, fixed my network by modifying rc.conf file again.
I have to fix the local area settings like time, zone etc. and something is wrong with the xserver (the fonts are too big) but generally - it WORKS
Thanks for your help attempts
Cheers. Staying with Arch -
Powerbook won't boot up! Please help
So here is the story. I recently cracked the screen on my 12" Powerbook on my way to school, so I have been looking for a replacement for a while now. I found someone on craigslist who was selling the exact same powerbook but the motherboard/logic board was out. I bought it from him for cheap hoping i could use the LCD screen to replace my broken one. Also, his had a DVD R burner and mine only had a CD burner so i replaced that also. I went into the computer and did all the necessary changes and put it all back together.
I thought it was all good, but when i boot up the computer, the screen is black and there is no chime or anything. The fan and DVD drive sound like they are moving and on and the caps lock button lights up, but thats it! It hums for about 5 minutes then shuts off.
If anyone can help, that would be great! Thank youI used the cable that was with the DVD drive. Then took that out and put in my old CD-RW drive with its own cable and that worked and it booted up.
I only swapped the screens and not the logic board.
Is there something wrong with the DVD drive then? it was plugged in to the logic board and it didnt boot properly. -
Gray Screen - Mac Won't boot from DVD, Please Help!
Hello all
I have an issue. A big issue in fact. I made a fatal mistake of not reading whether my Mac Pro (1,1 1st Gen, 2006) supported Windows 7 64-bit. So I installed via the Bootcamp installer on a separate internal HD and ever since my Mac Pro will not boot up, it just boots into a gray screen and I get the spinning wheel of death. I can however, boot into Safe Mode.
Throughout the years and many moving of houses has meant I have lost my original install disks, so I purchased a retail copy of Snow Leopard (10.6.3 / MC573Z/A). My thinking here was that something is obviously screwed and perhaps a good ol' fresh installation of OSX would do the trick. My Mac originally came with a version of OSX older than Snow Leopard so I'm not violating the can't-install-using-an-older-version-that-what-your-Mac-came-with rule.
Cutting a long story short nothing I do can get the Mac to boot from the install DVD. I've tried the following:
1. Holding down 'c' at start up
2. Selecting the startup disk to be the DVD from Settings within Safe Mode
3. Holding down alt + option key then selecting the DVD
4. Holding down apple + option + shift + delete (read somewhere this forces the Mac to ignore it's desire to boot from the main partition and boot from next available device)
5. Tried resetting the NVRAM
6. Repaired disk permissions from within Safe Mode
All unnecessary periphals have been removed. I have yet to remove 3rd party RAM admittedly.
Really struggling for ideas now.
Is there any hope for me and my beloved Mac Pro?
Many thanks for your suggestions.Right, another update. This coffee stuff really works!
Did a bit more digging around and found the following forum threads:
http://forums.macrumors.com/archive/index.php/t-1241149.html
http://osx86.wikidot.com/known-issues
Anyway, turns out the chap in the first forum link had the exact same problem as me. He temporarily got around this by removing the following files from the following location whilst in Safe Mode:
Location: /System/Library/Extensions
Files:
NVDANV40Hal.kext
NVDANV50Hal.kext
NVDAResman.kext
NVSMU.kext
GeForce.kext
GeForce7xxxGLDriver.bundle
GeForceGA.plugin
GeForceGLDriver.bundle
GeForceVADriver.bundle
I decided what the heck and moved these files into a new folder on my desktop and deleted the originals.
Sure enough my mac now boots up normally!
So it seems that the graphics card was the issue. I have read about the NVIDA 7300 GT only supporting 32-bit, but my tekkie understanding is not enough to know 32-bit what? I thought OSX was a 64-bit OS? If so, then why had it worked all this time? Only when I mistakenly installed Windons 7 64-bit did all my problems start.
Anyway, looks like I'll need to find a suitable replacement. -
When I try to activate my FaceTime from my iMac is says," the server encountered an errorprocessing registration. Please try again later." Please help. Any ideas
Back up all data.
Take the steps suggested in this support article:
FaceTime, Game Center, Messages: "There was an error processing registration" when signing in
Sign out of iMessage:
Messages ▹ Preferences ▹ Accounts ▹ Sign out
Then sign back in with your verified credentials. Note that the password of some Apple ID's will expire periodically.
If you get the same error, try resetting the NVRAM. -

How to manage a failed OS X Mavericks installation | MacFixIt - CNET Reviews.
Try these in order:
1. a. Resetting your Mac's PRAM and NVRAM
b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
after the chime press and hold down the OPTION key until the boot manager screen appears.
Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -
27" iMac won't boot from anything BUT the main drive
Hi all,
My lovely 27" iMac is in perfect working condition, but I thought I'd try to install a OS on a large SD card to see if I would gain any speed.
In the process of doing that (cause I never got that far) I discover that the iMac won't boot from the original install DVD. It simply spits out the DVD when I try to insert into the drive. I'v managed to make an image of the DVD (in a different mac) onto the SD card in order to try an boot from that. No luck. I've tried to insert a original install DVD from my Mac Pro into the iMac, which it reads fine and well, and when I tap the restart button it restarts, but stop with a white screen doing boot up.
If I try to hold down the option key during startup, the iMac WILL let me choose which OS to boot from, but if I choose anything else than the OS already installed it freezes.
I've even tried to boot my Mac Pro from the iMac install DVD - no problems.
I've even run a hardware test on the iMac - no problems.
I am running out of options fast! Please help a devoted Mac-friend.
Take care.
PeterI WAS using the DVD that came with the machine, but I fear Apple may have sent me the wrong one?
In trying to solve the issues I'd tried other OS disc's (A Mac Pro install DVD and a OS X Leopard DVD) - but none of them would even boot, nor install of my iMac. I always end up with a white screen during boot up.
As I described, the original iMac install DVD would indeed boot my Mac Pro, do the disc seems ok? -

My iMac won't boot up past the white screen with a grey apple and spinning icon
My iMac won't boot up past the white screen with a grey apple and spinning icon...please help!
command R did not result in anything different - still the white screen, etc. I do you Time Machine with and external hard drive, but I unplugged that. I have the installation DVD, but it doesn't seem to be reading it either.

Hey, any help? My 24" iMac won't boot. I only get a white screen when turning on. It won't open in safe or recovery mode. Any suggestions?
If you can't boot from your installer DVD, then take it in for service.

My iMac won't boot past grey screen and it didn't come with a os x disk
My iMac won't boot past grey screen with apple. I've tried booting in safemode but that didn't help and my iMac didn't come with a os x disk.
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -

IMac won't boot after power outage
I got a power outage a couple of hours ago. And now my iMac won't boot. When I power it up, it gets pass the white screen with the apple logo. The screen than turns blue with a spinning cursor. The cursor spins for about 10-15 minutes and stops but the normal login screen never appear and it won't boot into the desktop either. I just got a blue screen.
I have boot into the install Disc1 and did the disk repair and premission repair but it didn't help.
Any idea?
SidneyOh man, what a disaster!
I tried to do an Archive and Install but the installation hanged at the end of disc 2 after running an iWeb script (according to the install log) with about one minute left. I have waited for two hours but it just hanged there with all the drives spin down.
To make the problem worse. There was no way to quit the install at that point because all the menu items were disabled. The only way out was to power off. But when I powered it back on, it booted right into install directly asking for the disc 2. If I put the disc in it will install again and hang at the same spot.
Disc 2 contains iLife. I know Apple wanted to make things simple but why can't they give me an option to skip it? After all, iLife was already installed.
I finally got it working by booting from disc 1 and did a clean install. It took me all night to re-download all the updates and reinstall many applications. Fortunately, I have my address book, calendar, and most of my works backed up to .Mac so it wasn't a total lost.
On the bright side. Now my iMac is working better than before. I used to have problem getting auto sleep to work but now it works perfectly. Safari also had problem accessing charts (but Camino was fine) in a few web sites like schwab.com. Now everything works.
Lenn and David. Thanks for all your helps.
Now I am looking for a better backup solution so that the recovery won't be this painful if disaster strikes again. Any suggestions?

IMac won't boot at first attempt
Hi
Recently I've been experiencing that my intel iMac won't boot at first attempt and I have to powerdown manually and then try again. Second time it boots just fine. It's usually in the morning (been shut off for the night), but not always. I've tried disc utility from the install dvd, have repaired permissions and reset the nvram and everything seems just fine. The thing is, this has happened after the 10.4.8 update as far as I can remember. Does anyone else see this or is it a coincidence and some other problem?
Any thoughts would be appreciated.
Best regards
Rico
intel iMac 20" Mac OS X (10.4.8)
intel iMac 20" Mac OS X (10.4.8)Oups, sorry about that wrong quote - I've been reading to many discussions lately
I've done all sorts of things today and I'm kind of curious to what is going to happen tomorrow morning when I boot up the mac. To sum up, here's what I've been doing:
Installed 10.4.8 manually, downloaded from: http://www.apple.com/support/downloads/macosx1048updateintel.html Read somewhere that the stand alone installer might help.
I ran repair permissions right after and got this:
Permissions differ on ./usr/standalone/i386/boot.efi, should be -r-xr-xr-x , they are -r--r--r--
Owner and group corrected on ./usr/standalone/i386/boot.efi
Permissions corrected on ./usr/standalone/i386/boot.efi
The privileges have been verified or repaired on the selected volume
Ran repair permissions again to check - all was good
Enabled automatically login in the accounts menu in user prefs - someone suggested me to do this, but I'm not sure what that might do, but hey, I'll give it all a shot.
Changed resolution and then back again to highest possible. Apple suggests this when the problem occurs on the 17" iMac.

Unplugged power cord for 30 secs and reset smu (G5 article/idea though)
http://docs.info.apple.com/article.html?artnum=301733
Used Onyx to delete the content of library > caches which I read somewhere could perhaps help.
I'll post again tomorrow morning, and hopefully with some positive news
