PowerMac G5 OS 10.4.11 Won't boot

Hi,
This morning one of our MacPro G5 wouldn't boot. Power LED stays solid on, but no chime, no video, no nothing. It won't even recognize the keyboards (tried different ones just in case), so I can't even try to boot from the install media nor clear PRAM or access Open Firmware.
Removed all external peripherals, so I only left the keyboard, mouse and display.
Any suggestion besides taking it to the shop will be greatly appreciated.
< Edited by Host >

Mac Pro 3,1 is not a G5 (PowerPC). Just don't try G5 tricks on Intel Mac, like lack of OPEN FIRMWARE. One person managed to do something booting and rendered their motherboard into a doorstop.
Apple's first suggestion is to unplug for couple minutes to help reset SMC. I'd go longer and further probably.
Not enough to go on but check video card, RAM, Risers and see if you can boot the Apple Hardware Test.

Powermac G4 (OS 10.4.11) won't boot past grey apple

1- My PowerMac G4 (running OS 10.4.11) won't boot past the grey screen with the apple. Any suggestions?

I found somewhere else how to hold down the mouse on starting, which opened the tray. I was able to startup with the disk, holding down the C and get to the Disk Utility window. Tried repairing the disk, but got this message:
Fist Aid failed:
Disk Utility stopped verifying "Macintosh HD" because the following error was encountered:
The underlying task reported failure on exit. <OK>
and in the info window it says,
"Verifying volume "Macintosh HD"
Checking HFS Plus volume.
Catalog file entry not found for extent
The volume needs to be repaired.
Volume check failed.
Error: The underlying task reported failure on exit (-9972)
1 volume checked
0 HFS volumes verified
1 volume failed verification
Sounds pretty ominous! Of course, the recommendation is that I backup everything , but how can I if I can't get to the desktop to back it up? (It hasn't had a lot of use for sometime, but is available as a film scanning station, and so that I can access scanned images on my iMac. I doubt that there is a whole lot on the drive that isn't backed up, but I would prefer to back it up for sure!)
Thank you again.

Powermac G5 - ocz Agility 4 ssd won't boot

G5 Power mac - ssd storage upgrade - ssd drive won't boot when blessed.
1. Installed 2 new drives into old G5. Upper slot - 2TB sata hdd, Lower slot - 256GB ssd OCZ Agility 4.
2. Formatted both drives as Mac OS extended (Journalled).
3. 2TB drive partitioned into a 'Data' partition. (~90%) + a 'Backup Boot' partition (~10%)
4. Installed 10.5 onto the ssd.(Named 'System 10.5')
5. Restarted system as part of install.
6. System booted back to installed disc.
7. Went into 'Startup disc'. Selected ssd with 10.5.
8. Restarted system. System still boots to install disc.
7. Installed 10.5 onto 'Backup Boot' partition on 2TB drive.
8. System restarts OK.
9. From 2TB hard drive system. set ssd to startup disc.
10. System restarts to 2TB hdd.
11. Restart system, hold down option, ssd appears. select as boot disc.
12. System boots to ssd, and the welcome animation starts to complete the install.
13. Download the 10.5.8 combo update and install.
14. System doesn't reboot to ssd, but 2tb hdd.
Aware the booting requires a system folder (drive) to be 'blessed', I started poking around the web to verify if the ssd was set for the startup.
Running the command : 'bless -info' returned the following:
finderinfo[0]:    215 => Blessed System Folder is /Volumes/System 10.5/System/Library/CoreServices
finderinfo[1]: 239774 => Blessed System File is /Volumes/System 10.5/System/Library/CoreServices/boot.efi
finderinfo[2]:      0 => Open-folder linked list empty
finderinfo[3]:      0 => No OS 9 + X blessed 9 folder
finderinfo[4]:      0 => Unused field unset
finderinfo[5]:    215 => OS X blessed folder is /Volumes/System 10.5/System/Library/CoreServices
64-bit VSDB volume id: 0x9FC3EB20743384E4
So the system was 'blessed'. Tried the 'option key' method at startup but still not getting the ssd to appear as a valid boot option.
Looked on the OCZ website which has a Mac OS boot utility for flashing the firmware on the ssd drive BUT the drive is already on the current firmware : 1.5.2
Running out of ideas, short of re-formatting and re-installing the system onto the ssd.
Any ideas of other fixes?
(Feedback really appreciated).
Screengrabs of sata drive profiles attached. (hopefully)
Thanks in advance.
Ps. Ssd drive appears on desktop reads / writes / etc when booting into the hdd.

THANKS BDAqua FIXED !!
I hadn't installed the ssd into the top slot due to not being able to easily fit the apple rounded hd screws into the mounting tray - hence just letting it sit in the lower position. By working out the holes of the OCZ tray with some other hd screws, I was able to fit the apple hd screws then slot into the top (upper) position & the 2tb drive in the lower position.
Now all working as expected. Thanks again.
Matt.

Powermac G5 1.8Ghz June 2004 won't boot anymore

Hi all,
Past week i've bought a second hand PM G5. At first it seems to be all ok, but right now its not working anymore.
I've managed to install the OSX on the first evening i've had the PM G5. After installing evrything seemed to be fine. But after 30 minutes surfing on the internet, it froze. I had to give it an hard reset by holding down the power button.
After turning it of, it won't boot anymore. after a few times trying with 10 secconds between it, i unpluged the powercabel for 2 minutes. Wile turning it on after 2 minutes, it was booting , but it stopped booting after 1,5 minute and froze.. after hard resetting it, i've managed to boot it right. The OS seemed to be ok again, but after 5 till 10 minutes it froze again.
Right now it won't boot anymore... it starts (without the front light, this light only blinks fast once i turn it on, but after that no more. Sometimes it won''t even flash.
I've been buzzy replacing some components to get to know if it was a hardware fail. I've first replaced the PSU with two other PSU's from the PM G5, but won't do a thing.
The i've replaced the memory with 4 kind of difrent pairs, but won't do a thing either. At last i replaced the Logic Board, this won't even do a thing about it.
Of course i replaced the PRAM battery first, but also this won't help me.
I've tested it in AHT, but evrything was working well, according to AHT. I've managed to get the system log, but nothing scarry though here also, only some 122 errors some times. (download the system log here: http://www.mijnbestand.nl/Bestand-F4DDN66WLRCI.log )
I've reset al things possible like PRAM reset, PMU reset. Nothing seem to be working.
What can i do next to get this thing work?? I'm getting nut's here..
Please help..
Thanks a Lot
MArtijn Snoek

Hi martijnsnoek, and a warm welcome to the forums!
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
http://support.apple.com/kb/HT1547
So, with the info you given, two things come to mind...
Bad solder joints around the RAM slots, try heating that area with a Hair Dryer for 3 to 5 minutes, then see if it starts.
If you can get it running, Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
And/or iStat Pro...
http://www.islayer.com/apps/istatpro/
If you have any temps in the 70°C/160°F range, that's likely it.
BTW, have you blown the dust out of it since you got it?

PowerMac G5 won't boot, but loads OS X/Linux install CD. Help?

I have a PowerMac G5 with a problem: It won't boot. I tried resetting most things and then finally tried formatting and installing linux (Ubuntu 12.04 PPC). The install appeared to work but on reboot I got a white screen and from there the fans slowly went to full blast.
(The white screen and fans happened before linux, too) The drives work perfectly. The hardware must not be completely dead because it can boot from a cd. Can someone help?
Specs: G5 1.8 ghz(DP), 8GB RAM.

I've not convinced it could not be a harddrive problem.
I'd get an external hd & try installing to the external hd or get another internal hd & try installing to that. You need an external bootable firewire drive.
You need an external Firewire drive to boot a PowerPC Mac computer [ a few G5's will boot from USB ].
I recommend you do a google search on any external harddrive you are looking at.
I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.
I'd give OWC a call. 1-815-338-8685.
FireWire 800 + USB 3, + eSATA
save a little money interface:
FireWire 400 + USB 2.0
This web page lists both external harddrive types. You may need to scroll to the right to see both.

You could run hd diagnostics.

Does it work from a linux live hd? Ubuntu 6.06 LTS
I recall Ubuntu stopped supporting the PPC in '96 / '97. Anything later is community supported which for my iMac g3 was unreliable. I had to mess around with the x11 configuration to get the display working. Can you get into command line?
Ubuntu 6.06 LTS with x11 configuration changes worked for me.

The Ubuntu folks stopped supporting the power PC a while back. You will have to install an older version of Ubuntu.

Powermac G5 won't boot - but safe mode works fine!!!

[The computer described below is a Powermac G5 dual core 2.7gHz, purchased in late 2005, running OS X 10.4.11]
Here's an odd thing... a few months back, my powermac stopped booting. It wasn't a power supply issue. I would get the white screen with the apple to come up, but when it was time for the blue screen with the user logins, the screen would go black.
I tried swapping out all the RAM, and nothing worked. Was able to get safe mode to work, once, and then never again. Finally I broke down and took my baby to Tekserve.
Tekserve took a MONTH to get it back to me, and they claimed it was a bad RAM set. This sounded really odd to me, since I thought I had correctly tested several sticks of RAM, and even no RAM, without any success. But I'm not one of the experts, so, hey. My computer was running again and that's all I cared about.
Well, now, about 3 weeks later, my computer will not boot. It started with the loud fans. Now I'm not having any fan noise, but it still won't boot. Here's how I've troubleshot it so far:
- The computer boots FINE in safe mode. I verified the disc in safe mode, and everything checks out. Everything also checks out using fsdk -fy in single user mode. So no disc problem, apparently.
- When I reset the PRAM using crtlopt+pr after the chime, the screen resolution changes from 1200x1024 to 800x600. After the white screen, I do get the blue screen, but WITHOUT any user login, and the mouse cursor does not show up.
- When I reset the NVRAM using open firmware (reset-nvram, set-defaults, reset-all), I'm back to my normal problem of white screen followed by black nothingness (and emotional despair).
Tonight I'm going to try swapping out the RAM again, but if that doesn't work, what's next? I don't know where I put the original Hardware Test DVD that came with the powermac... is there a program I can buy to see if this is my logic board, without bringing the powermac back into tekserve? I live in NYC and have no car; bringing this heavy item into Manhattan is a real issue for me!!!
Anyways, any and all info is greatly appreciated. I really hope I'm overlooking something obvious. Natch, neither Apple nor Tekserve want to give me any advice without me shelling over more of my hard-earned cash. And this all went down 3 months after applecare expired... sigh...

Very interesting... they're telling me (at Tekserve) that this problem is caused by bad sectors in my SECONDARY drive. Doesn't make any sense to me at all, but that's what they're saying... pretty sure the RAM and video card are fine. I tried resetting NVRAM and PRAM, and that did nothing... safe mode works fine, as I mentioned... even got it running in normal mode for about 30 seconds one time.
It's the shop now, so we'll see, when I get the computer back, what the real problem was. It makes me flabbergasted that bad sectors in my secondary drive could have any effect whatsoever on boot!

Powermac G5 won't boot past apple logo screen

I'm trying to repair a Powermac G5 (dual 2.0, the first model I believe, with a new Radeon 9800 graphics card) that won't boot and I'm having some problems that I can't seem to diagnose.
The machine will boot to the openfirmware prompt or target disc mode and will show the 'OS not found' icon if left to boot from the HD (which has been wiped). If I try to boot from either the included restore disc or a retail 10.4 DVD I've tried it will show the boot screen with the Apple logo on it but no spinning status indicator underneath. It just freezes on that screen. Once it showed the status indicator but it just continued to spin for about 30 mins, at which point I gave up. Same issue if I try to boot the hardware test (except it freezes on the hardware test loading icon rather than the Apple icon). The superdrive appears to work as it is accessible in target disc mode.
I've reset the SMU and reset the PRAM via the keyboard shortcut. The one thing that leads me to think it's a firmware fault is that when I run the 'reset-nvram' command it gives an OK, but when I then run 'reset-all' it freezes rather than rebooting. Any ideas anyone?

I am having the same problem with my Power Mac G5. I have had a problem with the machine for the last few months, I just turned it off waiting for Leopard (started using a laptop for projects).
I got Leopard, tried to boot off the DVD, I only get to the grey Apple logo and then after a few minutes the fans kick on high and I just have to shut the machine down.
I didn't want to lose any thing off my hard drive so I went and bought a new one and installed it, when that failed to install to, I bought a new optical drive. It still won't boot off the optical drive. I can go into the firmware and choose which drive to boot from (I choose the optical).
My configuration at this point is a new DVD drive, new unformatted hard drive, I have used a laptop to try to install from using the G5 in target mode, using the laptop in target mode to use as an optical drive. All of these steps have failed.
I have 4 gig of RAM, Pioneer 112D DVD, Maxtor 250 Gig HD, I have reset the SMU, I have the NVidia card (can't remember which model).
Any ideas where else to look for a solution?

G4 PowerMac mirrored drives won't boot after software update

This IS NOT about my PB but a PowerMac tower, G4, mirrored drive....running 10.5 (I think).

Now it won't boot.
I have a Disk Warrior CD, but I can't get the SuperDrive door open to try to boot from it.
Help GREATLY appreciated.
Thanks,

Updating
Certain steps appear to minimize the risk of an update producing problems.
Number one is to make sure you have a bootable clone backup of your computer in case you do need to back out of it again. This is the only guaranteed way of not having to worry about the results of an update.
Some like to boot from their installer discs or an external backup and verify (and if necessary repair) their internal drives as well as drive permissions. This is done with Disk Utility. You can verify a drive while booted from the same drive but sometimes this produces spurious errors. Repairing a drive (if necessary) has to be done while booted from another disk. Permissions repair can, and is probably best, done when booted from your internal drive.

[Disk Utility's Repair Disk Permissions|http://docs.info.apple.com/article.html?artnum=25751]
You can also go to the step of booting into safe mode to do the install.

[What is Safe Boot, Safe Mode? (Mac OS X)|http://docs.info.apple.com/article.html?artnum=107392]
[Safe Boot takes longer than normal startup|http://docs.info.apple.com/article.html?artnum=107394]
I like to download the update onto my computer and install it from there rather than let Software Update do it. I know a few people who had problems with doing the update via software updater found a manual install to work.
Repair permissions again afterward.
It helps to only install one update at a time and to run the computer for a while to make sure it is behaving well.
The more cautious even like to unplug third party peripherals (see [comment by BDaqua|http://discussions.apple.com/message.jspa?messageID=9040746#9040746]).
Almost all of the above steps (except backup) have been questioned as to necessity because probably many people have done successful updates without doing them. I say they can't hurt, they can very likely do good (especially if your computer isn't regularly maintained), so why not do them to be safe.

PowerMac MDD 1.25 Dual G4 won't start..

Abruptly this PowerMac MDD 1.25Ghz Dual G4 won't start up. The button lights up, but there is no other reaction from the PowerMac. I have already reset the PMU on the logic board. I have replaced the CMOS battery. I removed the hard drive and copied important data off it. Any other suggestions before taking it to my local Authorized Apple Repair Station.

wouldn't it be more prudent to just replace the "wind tunnel" power supple
As a matter of troubleshooting, no.
After testing and confirming, yes.
Used and refurbished power supplies are available on eBay.
The 360W MDD PSU, having revamped fans, is the desireable one.
I'm thinking of just taking it in and have them check it out.
A third party repair service might be fine. Apple will just say it's too old.
I'm sure I can replace the power supply myself.
http://www.youtube.com/watch?v=uEfNH1DaJUo
Where is this capacitor located? inside the power supply?
Inside, where it is very dangerous for the non-trained to access and repair.
PSU components hold deadly charges long after they are unplugged.

PowerMac G4 Won't Boot

I recently got a PowerMac G4, and have had the thing for a month or so. For the entire month, everything seemed to be working fine. A few ownership changes here and there to allow for reading/writing, but nothing major. After shutting down the Mac (something I regularly do) and restarting it, the machine turned itself off. Restarting, I pushed Command+V to show output.
I get the normal boot messages, but then the machine pauses at this:
jnl: unknown-dev: journal start/end pointers reset!
After that, it continues loading for several minutes, then repeats this line approximately 20-30 times within a 1-2 second period before turning off:
USBF OHCI Driver: OHCIRootHubPortPower bit not sticking (0), Retrying
I removed my third party USB PCI card, to no avail. The only thing I currently have plugged into the logic board USB port is the Apple keyboard and mouse.
Any help would be greatly appreciated.
For the record:
2GB RAM - Reseated and tested
PMU has been reset.
All PCI and video cards have been removed to ensure they aren't the culprit.
Red LED light on motherboard above memory is illuminated.
Machine won't boot off CD.
When the machine is turned on, I do get the Apple boot screen, but when it should switch to the login prompt, the machine powers off.

HT1752 Liquid On Top of PowerMac G4 Tower, Won't Boot

Liquid got onto the top of my PowerMac G4 tower. Now it powers up but won't boot. Has only the logic board been fried, or could there be even more damage? Any chance of recovering files from the hard-drive?

Impossible to tell what is damaged, but pull the Hard Drive & try something like this...

PowerMac G5 won't boot in one location

Here's a strange problem. We have a pair of PowerMac G5's. Second and Third generation. They boot fine from my place of work. But at my new residence, they do not boot at all. I went back and forth between the places 3 times. Yet I can't even get to single user mode (UNIX prompt).
I tried plugging the computers into each grounded circuit in my house. I first tried it with my new 20 amp outlets (20 amp each). I had a qualified electrician come to my house and tell me that the outlets are "clean": well grounded, good voltage (4 volts over "you get what hydro gives you"), etc.
I know that the G5 draws a lot of current when it starts up but according to my electrician, my circuitry should definitely be able to handle that plus a whole lot of other guear.
A G5 iMac works fine. All my PC's work fine. I did discover a dead power supply on one of my routers, but I don't know if it died before or after the move.
I've searched the apple site and web and couldn't find anything on this topic, which is even more baffling. I don't believe in singularities within mass production--I can just assume that anyone who has experienced this has not posted, or applecare might be able to provide an answer.
My next move will be to introduce a UPS, such as the Belkin UPS Line Conditioning And 4 Battery Backup (550VA), e.g.,

Needless to say, I'm completely floored by this problem, and so is our IS/IT staff.
So if this is not a question, it's at least a post "for the record".
Thanks,

Well, I searched the web all over, and Apple's web site, and I even phoned Apple's tech support who took several minutes to research this: I found no solution to my problem. So I'll describe the problem and the solution. (Maybe a better googler would have found the solution, but Apple couldn't help!)
To recap: I moved to a new, older, house recently. I installed 4 20 amp circuits to handle my equipment (over $1,000 for this). I plugged in my PowerMac dual G5 (second gen) and tried to boot it up. Nothing. Wouldn't even get to the command prompt, though the power light was on. Tried every outlet in the house. I brought this computer back and forth to my workplace, making minor modifications as you would expect for debugging (resetting pram, etc., swapping RAM, etc., etc.). Nothing worked. So I tried a different PowerMac G5 (3rd gen). And this one had the same problem. Bizzaro.
I had the electrician come to my house again and he measured several of the outlets and said they were all clean. All within the specs of Apple. Voltage was a bit high but within normal range. He even measured it during the attempted boot up.
I tried a UPS. It idn't work. I phoned APC, and they told me that they have frequently fixed PowerMac G5 users' problems with their:
APC Model SUA1500: line interactive UPS, pure sine wave, list price = $US 519. So that means my original UPS just wasn't good enough--lucky I pursued that further.
So that would be my solution, assuredly. I won't even bother to buy the thing, cause the price is too high and I don't know how long I'll be staying here. So I've been demoted to an iMac 1.8Ghz. Better than using a G4 anyway.

PowerMac won't boot after power failure during install

Hi, sorry if this has been asked. I searched, but I'm not quite sure how to phrase it.
I bought a used PowerMac from craigslist and went to install a newer version of OSX. I had a power failure in the middle of the install and now the computer won't boot up. How do I go back to a fresh re-install and get the computer to boot up?
Much appreciated!

Did you use a retail install DVD? If you used a gray disc from another model Mac, that could be a problem.
Because of the power failure, suggest you reset the PMU. How long was the power Off? You may need to replace the PRAM battery.

OS 9 Powermac G3 Won't boot from CD

My OS 9 CD won't boot on my B&W G3. I want to install OS 9 and then install OS 10.3 on top of that but I can't get it to boot from the OS9 CD. Any ideas?

The Option key at startup should bring up Startup Manager where you can select from available startup disks. If you have the Mac OS 9 disk in the drive, it should be one of the options. Your Panther system should be another option.
If you are using a non-Apple keyboard, I'm not sure it will work, but the Option key is the Alt key on a Windows keyboard. If you were using the C key at startup to boot the optical drive, maybe that's why it did not work, because it was not an Apple keyboard.
A dead PRAM battery can cause startup problems. If it was very weak, resetting PRAM may have drained it the rest of the way. It looks like this

If you have a voltmeter, you can check your battery to see of you get 3.6v.

PowerMac DP G4 Won't Boot With All RAM Sticks Installed

A few weeks ago, my 800 MHz dual-processor G4 started having frequent kernel panics. I tried all sorts of things, including changing the PRAM battery, resetting the firmware, and resetting the PMU. Then, one day, it would only power up but not boot, so I took it in for repairs.
The shop I took it to determined that the logic board was malfunctioning and replaced it. The computer no longer has any kernel panics.
The machine was designed for three 500 MB RAM sticks, which is what it had ever since I bought it over five years ago. Now, apparently, it won't boot with the last one installed, though it will with two. The shop replaced the new logic board and and even swapped RAM, but the problem still persists. Neither the power supply nor the hard drive appear to be malfunctioning.
Does anyone have any ideas what's going on? Any ideas or advice would be greatly appreciated.
Thank you.

squeakmaster, welcome to Apple Discussions.
Have you tried the following with one 512MB RAM stick:
1. Palce it in the first RAM slot. Does the Mac boot?
2. If so, remove the stick & place it in the second RAM slot. Does it boot?
3. If so, remove the stick & place it in the third RAM slot. Does it boot?
The results of this test should reveal (1) if the stick boots in one or more RAM slots, the RAM is good and (2) if it fails to boot in a RAM slot, there is a problem with that slot.
Do this with each of the tree RAM sticks & post back the results.
When the logic board was replaced, was the firmware updated to be compliant with OS X. (Note - The firmware is installed on a chip on the logic board.) Check your Mac's firmware (Boot ROM version) version. Mac OS X: Available firmware updates
http://docs.info.apple.com/article.html?artnum=86117 If an update is required, the update must be installed (using OS 9) BEFORE you install OS X.
Can you boot up in OS 9.x? If so you can use DIMM First Aid - Check & recover disabled (missing) RAM from Apple's latest firmware updates http://www.versiontracker.com/dyn/moreinfo/macos/10415
