IMac crashed! Only get partial boot from OSX disk one

Booting from OSX disk 1, goes as far as a blue screen with no icons or menu. Boot with D key for hardware test. Test ok.
At a loss what to do next.
David

Does Seem so, or the Internal Drive is so messed up it's interfering, try this...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

Do I need to boot from OSX disk to repair permissions?

If the answer is no, how easy is it to copy Disk Utility to my hard drive?

Disk Utility should be on your Applications/Utilities folder. If it isn't, Pacifist can extract a file from an installer.

Can't boot from OSX and may have a virus

I'm having a similar problem as Davo21 in "computer won't boot up in os x". After running Norton System Works to try to resolve an issue that I was having with my computer, I'm getting a message, "/etc/master.passwd:not a directory" on a black screen when I try to start up.
It started in early December after I downloaded some stuff off the internet and it seemed like I might have picked up a virus. I know, that's not supposed to happen with OSX, but my computer started doing wierd things like switching out icons for whole types of files - i.e., .wav files would show up with a totally different icon. Restarting solved that problem, but I noticed that on both my wife's and my computer (both Macs - hers a Single core Intel Mini running OSX 10.4 and mine a G3 700MHz running 10.3.9) the internet was running exceptionally slow, while on my work computer (a Dell PC running Windows XP) it was running just fine. All three computers are networked, so I surmised that something was affecting the Unix system but not the Windows, but when I ran Norton Anti-virus, it came up clean. More wierd things kept happening, so last week I decided to run Norton Disk Doctor and it changed thousands of directory settings and now my computer won't boot up from my main boot drive with OSX 10.3.9. I've run the Disk Utilities on the 10.3 Install Disk and I've run Disk Warrior and they both say that the boot drive is repaired, but I still get the same message when I try to start up normally.
I have several partitions on my original drive and several more on the additional 240GB hard drive that I installed a couple of years ago, so I can boot up from an old copy of OSX 10.2 on another partition. The latest wierd thing is that now one of my other partitions on the original hard drive won't mount.
My questions are:
1) How do I get back to being able to boot from OSX 10.3?
2) Where can I get help to figure out what's going on with my computer and how to remedy it?
I've been looking at some of the information on the Leap-A malware and it seems like there are some similarities, however I'm running OSX 10.3.9 and not 10.4.
Any suggestions would be appreciated.
Thanks,

DMcSantaFe,
as was said before Norton Utilities and Disk Doctor were discontinued almost 3 years ago (for some very good reasons!). It caused much more trouble than it solved.
Here are the articles:
Symantec discontinues Mac Norton Utilities, SystemWorks
Norton Utilities, SystemWorks development halted
TMO Scoop - Symantec Confirms Norton Utilities & SystemWorks' Demise [Updated]
Tech Tool Pro and DiskWarrior are presently the most reliable utilities. For more information on regular housekeeping read this: MacOS X 10.3/10.4: System maintenance
Unfortunately Norton usually damages the file system beyond repair. The only cure is a reinstall.

Can't boot from OSX 10.6.3 retail disk

Hi.
I have a macbook pro and want to boot from a retail osx 10.6.3 disk that I purchased. When I try to boot from the disk I hold C or option on startup I get the apple logo with no spinning gear. It hands here for hours. Nothing happens. I hear the disk begin to work and then it shuts down.
I want to boot from the disk and install an instance of OSX on my external hard drive. I do not have administrator access to the main OS, so booting is my only option for install. Do I HAVE to have the repair disk that came with the computer or can I use the retail copy I purchased?
Thanks.

In a production environment we don't run around with the original media.
It would be nice to get a new retail release soon so I can throw it a few USB thumb drives and be able to do an install on the i5s, i7s and older core 2s. Anyone know when a newer retail DVD will be on sale?

IMac will only restart or shutdown from power button.

My iMac will only restart or shutdown from the power button, it also will not logoff users. It starts ok, but only after a hard reboot?? I have repaired permisions and no change. I have a clone I can restore from but any ideas whats up here?
The only things that I know I have altered are deleting files saved during migration from Panther (months ago)and running Unbuntu Live CD.

Are you booting into Ubuntu Linux? Most of us here wouldn't now anything to do with it. If the problem is occurring when booted into Mac OS X, it may be a sign of data corruption in the power management and user settings. Some corruption is easy to repair such as fixing the directory (which I'd only do after a clone). Here's how according to my FAQ:

And I assume the issue is with your iMac G4.

IMac 20" won't boot from AppleCare disk

Hello all,
I have a new (1.5 weeks) iMac iSight 20" and am thrilled with its performance (it does not have any noticeable noise, nor does it have any dead pixels). I have tried to boot it from the AppleCare disk (the one with TechTool on it) but it will not boot. I have used that disk to install TechTool successfully on the iMac HD, but it will not boot from that disk. The iMac will boot from the OSX install disk that came with the iMac, and I have done so in order to run repair permissions before and after updates. Is there something easy I'm missing regarding booting from the Applecare disk? I'm not new to Macs, but I am new to iMacs and OSX. Any help is greatly appreciated.

Hello all,
Acting upon the advice I received here, I called AppleCare. Although it took 32 minutes, they did finally agree that the issue was with the AppleCare disk, and they are sending me a new one. I did note one interesting thing. I visited MicroMat's web page to see what the most current version is of TechTool Pro, and it is 3.0.4. That is the version on my current AppleCare disk. I guess the incompatability must be with something else on the disk. Thanks for all the prompt replies and great advice.

Listeners only getting partial downloads

I keep getting reports from listeners of two of my podcasts that they are only getting partial downloads. It always seems to be about half of the episode (so on a 34 minute podcast they only get 17 minutes). Others download just fine, and when some re-download they get the whole episode later.
I'm using Wordpress with Podpress and Feedburner.
Anybody experiencing this, or know how to fix it?
Thanks,
Chooch

My sympathies - this happened to me last year too:

Eventually it stopped and I never got to the bottom of it, but I suspect it was a transient issue with the server.

Wallstreet not booting from OSX CDs

I'm still helping a friend with his two Wallstreet PDQs. The one I posted about in this thread is limping along OK as long as the owner keeps it on its cooling pad. Now the other, a 266mHz (OS 10.2.8 and 9.2.2 in separate partitions; 40GB Toshiba drive; 384MB RAM) started taking forever to boot. It appears it has a dead PRAM battery and is going to the OS9 system folder for booting but can't complete. It went to the Open Firmware prompt once but won't boot into OF now.
The computer will boot from an OS9 retail install CD and an older (v3 for OS9 and older)) TechTools Pro CD but will not boot into OSX from a retail Jag install disk or an OSX DiskWarrior v3.0 CD that previously booted OK into OSX on that computer.
Once I get an OS9 boot, the system cannot see the OSX volume where there are files I need to recover.
The TTP CD reported the drive is whacked--I can accept that--but, IMHO opinion, that should not prevent an OSX boot from a valid CD.
I have reset the PMU per Apple procedure, zapped the PRAM, tried to force an X boot with the X key, tried to get the Startup Manager by holding the option key--all to no avail.
Any thoughts on why I can't get a boot from an OSX CD? Even it the defective drive is removed, the Book should boot from an OSX CD. I know the CD-ROM drive works because it can boot from an OS9 CD.
I'd like to get one more X boot to recover files.
Thanks in advance,
Allan

Allan,
The left bay will not take an optical drive...it's too large, but it does take a Zip100 drive or an OEM floppy drive or media bay HD.
I'll explain the long startup times on the Wallstreet: After the startup chime, the Wallstreet runs a memory self-test that is just plain slow. The more installed RAM, the longer the test. When I first bought my Wallstreet, it had (gasp) 32MB of RAM; from startup chime to first light on the display was about 5-10 seconds. After I installed a 256MB module (total 288MB), this "dead" time increased to 40 seconds...really quite amazing. Resetting the PRAM, if I recall correctly, requires a long pressing of the keys to get that second startup chime. So if you are experiencing something similar, it is normal.
I cannot explain the 'out of memory' message when running TTPro but it may be the same when running DiskWarrior. When performing a major restructuring of a volume, ideally it is run from another volume that has read/write capabilities like an HD; the utility then has the necessary space to temporarily store changes. If running from the Utility CD, it can use up RAM pretty quickly. This again highlights the limitations of the Wallstreet...no easy access to another bootable HD.
The concern again returns to the inability of the Wallstreet to boot an OSX CD. If I had access to two Wallstreets, and has also tried all the suggestions up to this point, I would try this:
-Try the optical drive from the "working" Wallstreet in this 'book even though 9.x CDs boot; this is just a quick test to eliminate any possibility of a marginal drive; or you could test this drive on the working Wallstreet. Make sure you also try booting the same 10.2 CD.
-Swap one microprocessor card into the other Wallstreet and test. As I mentioned earlier, there have been a few Wallstreets (and Lombards) that would not run OSX and a replacement microprocessor card was the solution. Even though this Wallstreet has run OSX in the past, and since nothing up to this point has provided a solution, I would try this procedure if I had two Wallstreets.
See if your 'book will enter Open Firmware as an additional test of hardware:

Possibly dumb Q: Running Disk Utility when booted from OSX Install DVD

Hey there Mac folks. I was wondering about this:
I'm running OSX 10.4.5 on a 2x2.0GHz G5 with 4 internal drives. (I stuffed 2 into the PCI bay with a G5Jam bracket kit.) I use Disk Utility v10.5.3, which is current for OSX 10.4.5, when doing basic maintenance/repair on my secondary drives, as well as to repair permissions and do a verify (but not repair) on my startup drive. When I have to do a repair on my startup drive, barring the use of other 3rd party apps, I have to boot from my OS 10.4 DVD, and use the Disk Utility there. However, since it's a 10.4.0, the Disk Utility there is v 10.5.0.
So, the question: Should I care? Any chance of a problem? I know the Disk Utility's repairing doesn't really care what OS, if any, is installed on a drive it's repairing (at least I think that's true?), but I have no idea what changes/improvemnts have been made to Disk Utility. Actually, I've always wondered about this sort of thing since OS 10.0.
I think I can make a copy of my Tiger install DVD with the newer version of Disk Utility inserted onto it, replacing the old one with v10.5.3. I don't know if it's worth the trouble though. I figure that for the newbie users, Apple would have thought of this, and addressed it if it were a potential problem. (Despite this Q, I'm not a newbie!)

Hi, JonYo.
Booting from your Tiger Install DVD to Verify or Repair your startup disk is fine. No worries!
The major changes in Disk Utility from 10.5 to 10.5.3 were:
• Better handling of overlapped extent allocation errors. Third-party utilities, such as Alsoft’s DiskWarrior may still be better at this task.
• The addition of live verification: the ability to Verify your startup disk while booted from such. One of the intermediate releases
The key point is to only use Tiger-compatible disk utilities with Tiger.
If you've implemented a proper backup and recovery solution where you are creating a bootable duplicate of your startup disk, you could also start up from the duplicate and run the latest version of Disk Utility on such to Verify or Repair your usual startup disk. For advice on the backup and recovery solution I employ, see my "Backup and Recovery" FAQ.
Computing without a comprehensive backup and recovery solution is like driving without auto insurance.
Good luck!

Imac crashed and will not boot up

So my iMac crashed and will not boot. The power will come on and when it switches to the boot sequence it powers off. I bought Black Tie protection at Best Buy but when I took it to them they shipped it to Apple. The problem was never fixed. Apple said it was a software issue to reload the OS. Well i did that and not even a day went by and it is doing the same thing. Any suggestions would be helpful...

I agree with BGreg that you should run Apple Hardware Test , however run it in Extended Mode. If no errors turn up run it several times. It's a lengthy test so be patient. Also here is what Apple says about your symptoms in Gray progress bar appears under Apple logo during startup.
I hope you have been backing up your system, if not then if you can boot into Safe Mode as suggested you should immediately backup using either a clone or Time Machine. That should be the #1 priority to preserve your data.

TS5150 With certain movies I have downloaded digitally through Itunes or certain movies through Netflix played through Apple TV, I am only getting partial sound. I am missing one or more sound tracks. Am I missing something in the settings for Apple TV?

With certain movies I have downloaded digitally through Itunes or certain movies through Netflix played through Apple TV, I am only getting partial sound. I am missing one or more sound tracks. Am I missing something in the settings for Apple TV?

Are you using a stereo receiver or surround sound system for the audio by chance. What you are describing sounds like a receiver that is not setup correctly, or does not have the speakers connected to it correctly to support Dolby surround, 5.1 or 7.1. Which is why it is only happening on some content. It would only be on the ones that are encoded to support Dolby audio.

G5 gets grey screen with logo then goes black, won't boot from any disk

Won't boot from any disk, already changed VRAM battery, no success. tried hardware disk once and ran a full scan, said error with Video, but now won't boot at all with any disk. Screen is choppy also(have pic). Thinking video graphics card? Not sure. Need help!

Hi bribiel, and a warm welcome to the forums!
It certainly sounds like the Video card from the little info we have, & that can certainly cause it to fail to bootup.

New MacBook won't boot from external disk

I have a new MacBook that I am trying to boot from an external disk that had the system from my first gen MacBook Pro. When I restart holding the Option key, and select my external disk, the system restarts again and won't let me boot from that disk. Is there something different with the OS (10.5.6) that is installed on a newer MacBook that won't allow it to boot from the same OS from an older MacBook Pro?
Thanks

golferx,
Will any other Intel Mac boot from the drive? If not, it's possibly because the drive uses an Apple Partition Map (bootable for PowerPC Macs) instead of a GUID Partition Table (bootable for Intel Macs).
To check: open to Disk Utility, select the hard drive on the left, select the Partition tab and look at the text at the bottom right corner of the window under Partition Map Scheme. If it says anything other than GUID Partition Table, you will need to erase and repartition it as such before it will be bootable.
Just a thought. Hope this helps. Good luck!

I can boot an prev gen MacBook and also my iMac (current gen). I took it to the Genius Bar and he could not get it to boot a new MacBook either and didn't have a solution.

Though the root disk is mirrored, server is unable to boot from alternate disk (mirror disk)

Hi PPl,
It happened second time in a row. Though the root disk is mirrored, server is unable to boot from alternate disk (mirror disk)
When the disk was found faulty, still unable to boot the OS from alternate disk, it says it still probe/look for other disk
Here are the console log when I tried to boot the OS
sc> console
Enter #. to return to ALOM.
WARNING: /pci@0/pci@0/pci@2/scsi@0 (mpt0):
Disconnected command timeout for Target 1

In such condition left out with only two options.
1) Remove the faulty disk physically and boot
(or)
2) Replace the faulty disk and boot it
Any way, I can disable the faulty disk in BIOS (or) booting from cd-rom and do something to avoid it?

You can't boot from systems earlier than that shipped with the computer. For example, early 2008 Mac Pros come with 10.5.1 and can't boot 10.5
Also you can't boot with a DVD that was shipped with a different model Mac.

Booting from new disk drive

After copying all of my old drive onto a newer one I want to have all the computers that previously used the old drive boot into the new one. I can see the drive on my main server desktop but cannot boot from it. Any suggestions or readings you can suggest?

Several questions.
What application did you use to copy the files? SuperDuper! (full disk cloning is free; a very good app by the way). Carbon Copy Cloner? Both of these apps will clone a disk and make it bootable.
Were you able to boot from this disk before?
Is this disk an external firewire or USB? As far as I know all Mac with a firewire port can boot from a firewire bootable disk. I think only more recent Macs can boot from a USB disk.
You mentioned server. Are you by any chance trying to do a NetBoot? After all this is the *Networking and Web* forum. If so then the Mac OS X Server forum might be a better place to ask about NetBooting.
