Mac Pro won't start; please help!!

Had Mac Pro for 6 months. All was going well until today. Then I noticed my Mail application was not sounding a chime when mail came in. I repaired permissions and re-started my computer.
Only it did not re-start. I got no start-up chime and after the grey screen appeard, after about 15 seconds a dark blanket transition goes down the screen and a message comes up in several laungauges, English being:
"You must re-start your computer. Either hold down the power button for 8 seconds or press the restart button".
I held the power button in for 8 seconds, then turned it back on again, same thing...
I reset the SMC/Pram thing (whatever it is called) by doing it both ways i.e. unplugging every cable, then plugging in just power/keyboard/mouse, the other way was pressing the switch inside the machine; nothing.
My machine won't start up.
Any ideas?

What you're seeing is called a kernel panic. You can read more about what causes these and steps to take on the following web pages:

Mac Pro won't start up- HELP please.

I had a white screen a month ago .After buying a new harddisk and reistalling the whole system 10.6.5 and reistalling all programs from ground zero, I had the MPro working nearly for 2 weeks. But Suddenly today It got a frozen screem with a black curtain. I disconected all the external devices and after starting up I got a loading bar and then the spining wheel but it doesn't turn on.
Is this a sign that I need to change the motherboard?

You may be experiencing a Kernel Panic as seen and described in Apple doc.#106227. If not, disregard.
Bad or incompatible RAM is the most common cause of KP's. It could just need to be reset……. to make sure there's a good connection.
Try pulling any added RAM, especially if it's not OWC, Crucial or Kingston. Then run it with original RAM. Ground yourself while doing so. Keep in mind a bad stick of RAM can cause directory corruption, so Repair Disk after pulling the RAM. If it still does KP's, try removing the original RAM and running on two sticks of the added RAM.
Here's a great site for Resolving Kernel Panics. Please do all the steps in order, even if you don't think you need to do a certain step.
Here's a great MacFixIt article.

HELP Please, Mac Pro won't start up

Hi can anyone please help me??? Our power went out while my husband was out of town and HIS Mac Pro is just sitting there with the grey screen with the apple on it and the progress wheel spinning, it has been this way for over 2 days now and I am scared to death to shut it off or try to restart it!
Any suggestions??

1. Buy him an APC UPS 1500VA so power outage, brown outs etc are a thing of the past.
2. Kill it for now.
3. Make sure there are bootable backup clones - SuperDuper or Carbon Copy or another clone program.
4. Install OS X to a small 20GB partition to repair the main system.
5. Invest in 3rd party disk repair maintenance if you haven't already.

Late 2008 Mac Pro won't start -- help! Hangs up on Airport: RSN handshake complete on en2.

Hello Mac Pro user,
I have a late 2008 Mac Pro. It will not start anymore. The computer chimes and then goes to the Apple icon screen with spinning cursor, but then it freezes and goes no further.
So I did a single user start up [shift command S],then I let the info. load on the black screen, and found that the system hangs up at this line: Airport: RSN handshake complete on en2. Does anyone know what to do?
How do I get it to boot up again?
Thanks,
Yvette

pull the drives you have. ]
F'ind a way to do a clean system install on another drive.
Clone your user data to another drive also.
ie, create a new solid foundation.
but until your repair your drives, by booting off another device, don't use them. Pull them for now.

Help my IPOD won't start PLEASE HELP

It gives me the apple screen and then switches into the foloer with an exclamation point and i don't know how to get it out. I have tried restarting, and plugging it into the computer doesn't do anything. It is charged, please help.

Hello,
If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
http://docs.info.apple.com/article.html?artnum=60983
If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
Make sure you do all the following “TRYs”
A. Try to wait 30 minutes while iPod is charging.
B. Try another FireWire or USB through Dock Connector cable.
C. Try another FireWire or USB port on your computer .
D. Try to disconnect all devices from your computer's FireWire and USB ports.
E. Try to download and install the latest version of iPod software and iTunes
http://www.apple.com/itunes/download/
For old and other versions of iPod updater for window you can get here
http://www.ipodwizard.net/showthread.php?t=7369
F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
http://www.apple.com/support/ipod/five_rs/
G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
http://docs.info.apple.com/article.html?artnum=93651
If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
Intermediate Level
A. Try to connect your iPod with another computer with the iPod updater pre-installed.
B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
For Mac computer
1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
5. Eject your iPod and do a Reset
6. Open the iTunes 7 and click “Restore”
For Window computer
Go to folder “My Computer”
Hope you can see your iPod there and right click on the iPod
Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
Now select “Format”
Eject your iPod and do a Reset
Open the iTunes 7 and click “Restore”
In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.
http://discussions.apple.com/thread.jspa?threadID=501330&tstart=0
C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
Tips
a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iTunes 7.
b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

Advance Level
A. Diagnostic mode solution
If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
iPod 1G to 3G: "Menu" and "Play/Pause"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
iPod 1G to 3G: "REW", "FFW" and "Select"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
B. Format your iPod with a start disk
I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
If none of these steps address the issue, your iPod may need to be repaired.
Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
Or visit your local Apple Retail Store http://www.apple.com/retail/
In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ at your own risk
http://www.ipodresq.com/index.php
Just in case that you are at the following situation
Your iPod warranty is expired
You don’t want to pay any service charges
You are prepared to buy a new one
You can’t accept the re-sell value of your broken iPod
Rather than leave your iPod as paper-weight or throw it away.
You can try the following, but again, only do it as your last resort and at your own risk.
Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
Last Resort Level
1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)
http://eshop.macsales.com/tech_center/index.cfm?page=Video/directory.html
2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

Finally, I read a fair comments from dwb, regarding of slapping the back of the iPod multiple times
Quote “This has been discussed numerous times as a 'fix'. It does work, at least for a while. In fact I remember using the same basic trick to revive Seagate and Quantam drives back in the mid to late 1980's. Why these tiny hard drives go bad I don't know - could be the actuator gets stuck in place or misaligned. Could be the platter gets stuck or the motor gets stuck. 'Stiction' was a problem for drives back in the 80's. Unfortunately the fix can cause damage to the platter so we temporarily fix one problem by creating another. But I know of two instances where a little slap onto the table revived the iPods and they are still worked a year or more later.”UnQuote

Mac Pro Won't Start After Installing Security Update Tonight

I just installed the latest security update for Lion on my Mac Pro via software update. The update seemed to install fine. I was about to start work when all of a sudden the system rebooted on its own. Now it just continues to reboot because it can't complete the boot up.
I tried resetting PRAM and SMC, but this didn't help.
I tried booting up from CD using an old SNL disk. I was able to get to disk tools once. I checked my startup volume and disk tools said the volumes is fine. I was checking permissions when once again the system rebooted on its own.
I tried starting up in safe mode, but it only gets so far into the boot process before it reboots.
I tried starting in verbose mode, and noticed several SMC related errors (this is why I tried to reset the SMC). No joy.
If I leave the system sit a few minutes, it gets further into the boot process, but still won't boot completely.
Any suggestions?

My MacBook Pro won't start! HELP!

I've been away for two weeks and haven't used my MacBook Pro.
When I was about to start it again yesterday it won't start!

I tried several times and I waited for almost an hour but nothing happened.
The computer is about 3 years old.
Can anybody help me?

Will my hard drive be erased when I do the recovery?
Merely booting into Recovery won't change anything. Depending on what you do next, your data might be affected, so you have to back up first if you haven't already done so.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup; 10.7 or later), from a local Time Machine backup volume (option key at startup; 10.7.2 or later), or from your installation disc (C key at startup; 10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
3. 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.

Mac Pro won't start up. What's the best way to check the power supply?

Hello. I'm having a severe problem with my 2007 Mac Pro. The symptoms are very easy to describe. The computer apparently shut itself off overnight, and when I press the power button to turn it on, absolutely nothing happens. No lights, no chime, no signs of any power whatsoever in the computer. I have never had major problems with the computer before. (Although I had recently noticed some minor skipping problems with streaming videos and Firefox had started hanging occasionally.)
So far, I have checked the power cable and the power outlet. I have also reset the SMC (holding in the Power button for 5 seconds with the unit unplugged). I am unable to see any light in the diagnostic LEDs (including LED 1) when I press the DIAG_LED button on the logic board.
While I welcome other suggestions, all I can figure is that this is either a power supply problem or a major logic board failure, but I don't know which. I have a multimeter and would like to test very directly if the power supply is the problem, because they are very expensive and obviously I do not want to order a replacement supply if it would not fix the computer. Does anyone know what the best way to test the supply directly is? What pins on what cable should I test, and what voltage should I look for?
Also: No the computer is not under any warranty. If at all possible, I would like to fix this myself. Thanks for any help you can give.

Well, I may have found the answer to my question as to why replacing the fuse dows not seem to be encouraged. I cut out the failed fuse (fast fuse, ceramic, 16 Amp 250V), and replaced it with another that was as close to it in spec as I could find (15 A instead of 16). Then I put the supply back in the case.
When I tried to plug it in, I got an immediate spark, followed by an acrid smell from the power supply. Later inspection revealed that the new fuse blew, as did another component nearby (not sure what it was) where I could see blackening and the smell was concentrated. At this point, I would consider myself lucky if the power supply didn't take anything else on the computer out with it.
Lesson learned; will try a new power supply and go from there.

Hi Mylenium,
Here is the crash

Can't Update to 10.0.1, Bonjour Service Won't Start--PLEASE help!

All I want to do is update my iTunes but I cannot. It won't work from within iTunes, and when I try to do it manually it said "The Service Bonjour Service" won't start." In Services, I could not start it either, though I am admin.
So I deleted Bonjour (from within the Control Panel), thinking that'd take care of it, but it did not. I still get ALL the same messages. I even tried re-installing Bonjour (bonjour64.msi), and I get the same "won't start" message. It's not my firewall--I set that to always allow.
What is going on here? I've searched and searched, but to no avail (though they are plenty of Bonjour problems out there), and I really don't want to uninstall/reinstall iTunes, if that would even do it. I'm new to Apple, and this just makes no sense to me.
Please, help?? THANKS in advance~

There are remants of Bonjour in the program files, and I guess I could delete these to clean it up, but I doubt that would make the difference.
Actually, that could make a difference. If there is leftover componentry from the previous version still on the PC when the new version tries to install, the version mismatch could cause trouble with the new service starting. That could then roll back the attempted install.
There's a bunch of different stuff on 64-bit systems for BonJour (there's both 64-bit and 32-bit componentry stashed on a 64-bit system. We'll also try a cleaner version of an uninstall than the Apple instructions provide.
In Computer, open your C drive (or whichever drive your program files are installed on).
Open the "Program Files" folder.
Right-click on the "BonJour" folder (if it still exists) and select "Delete".
Go back into your C drive (or whichever drive your program files are installed on).
Open the "Program Files (x86)" folder.
Right-click on the "BonJour" folder (if it still exists) and select "Delete".
Go back into your C drive (or whichever drive your operating system is installed on).
Open the "Windows" folder.
Open the "System32" folder.
Right-click on the dnssd.dll and dns-sd.exe files (if they still exist), and select "Delete".
Go back into the "Windows" folder.
Open the "SysWOW64" folder.
Right-click on the dnssd.dll and dns-sd.exe files (if they still exist), and select "Delete".
Empty your recycle bin.
Restart the PC and try another BonJour install. Any better luck restarting the service this time?

Tried to download firmware update. My system wouldn't allow the installer to work. Apparently already have the firmware.
The Display icon shows only four choices for the monitors resolution. On my working systems there are at least 15 resolution settings. Where is the ATI Radeon software on the system. The About this Mac doesn't show any Graphics or Display information.
