G5 Dual 2,3 Ghz Keyboard Problem

Hi,
I recently powered up my g5 dual 2,3 Ghz (10.5.8) and when I beagan typing I discovered that many of the keys had taken on a second random function i.e. when I type "d", "d=" would appear.
I opened the keyboard viewer which shows that two keys are being pressed. I tried another (non apple) keyboard, however the problem remained. I have reset the pram and smu and restored all keyboard shortcuts to default with no luck.
I'm not sure what to try next, any help or suggestions would be greatly appreciated.

Hi, any other USB things plugged in?
Have you done a PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Fan speed problem Power Mac G5 Dual 1.8 GHz PowerPC - please help

Please HELP, I have a fan speed problem with my Power Mac G5 Dual 1.8 GHz PowerPC
This is a NOT an Intel machine. I am running Mac OS X v10.5.8
Power Mac G5 - PowerMac 7,2 - Power PC 970 (2.2) - 1.8 GHz with 2 CPUs - L2 Cache (per CPU) 512 KB - Memory 8 GB - Bus Speed 900 MHz - Boot ROM version 5.1.5b1
I have included below Links to download a sound file (.m4a) that I recorded of the fan speed problem and both a .pdf and .spx files of my system profile.

When did the fan problem start?
After I replaced the mother board on the computer.
Why did I replace the mother board?
Because the experts at apple agreed with my diagnosis that the major crash problems & kernel panics must have some thing to do with a logic board gone bad. They would not work on it, because this Power Mac G5 dual 1.8 GHz machine is now a legacy model.
What I have done to attempt to fix my fan speed problem? yes I checked the obvious things, here is a list:
1) yes I checked to be sure that the new mother board was the same part number as the original one, and that all things that were unplugged from the old mother board - were actually plugged into the new mother board.
2) all the fans work, I can see them spinning if I use a flashlight and look at them (cover on and off to get at some of them)
3) check all RAM to make sure: a) it was installed properly b) that the RAM worked using TechTool Pro c) even started the machine with only the original RAM that came with it.
4) I installed a Temperature monitor - to see if there was something reading as very hot inside that was causing the machine to continually run the fans at a high speed. No, no heat issues that I can see. Here are the reading from the sensors in degrees fahrenheit, 2009-10-11 16:11:01 -0500
CPU A Die Temperature: 75.7℉
CPU B Die Temperature: 81.5℉
Drive Bay: 68.9℉
Main Logic Board Air Inlet: 64.8℉

Main Logic Board Backside: 76.3℉
Memory Controller Heatsink: 93.2℉
Processor Card A Ambient: 77.5℉
Processor Card B Ambient: 77.0℉
5) zapped the PRAM
6) followed the SMU reset instructions for
Power Mac G5 (Late 2004)
To reset the SMU on a Power Mac G5 (Late 2004) computer, simply do the following:
• Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
• Remove the power cord from the computer.
• Wait two minutes.
• Plug in the power cord.
• Turn on the computer.
7) followed the SMU reset instructions:
Resetting the Cuda/PMU
How to reset the PMU:
• If the computer is on, turn it off.
• Disconnect ALL cables from the computer, including peripherals and power.
• If possible, move the computer to a place where you are not standing on carpet.
• Open the case and ground yourself by touching part of the metal frame inside the computer.
• Find the Cuda or PMU button
• Press the Cuda or PMU button ONCE. Do not press the button more than once before starting the computer up again.
• Wait 10 seconds, then reconnect the cables you removed in step 2 and turn the computer on.
• If the computer still does not respond after resetting the PMU, the computer may require service from an Apple Authorized Service Provider.
8) ran disk utilities, repaired permissions
9) found a setting in the system preferences that a chat room person suggested had something to do with fan speed. In Energy Saver, under options, processor performance was set to highest, I set it to automatic - this did not change anything that I could tell - BTW I checked my other G5 (a single processor that works fine) that is the setting that that it is set to, and it is nice and quiet.
10) restarted the machine, ..
11) found a Fan Control System Update - but it did not install when I tryed to install it -
12) booted from OSX install disk and ran that disk utility
13) used OnyX to fix disk permissions, clear caches and temp items
Nope - still have the same high speed fan problem. ... PLEASE HELP!!
I have been reading in the MacInTouch reader reports - found this: some one said to use this - thermal re-calibration using the Apple Authorized Service Providers' disk - but that's not available, at least I can not find it - anyone? have an answer to finding this - or can do it for me? I am in Chicago.

The Genius at the downtown apple store said that because it's a "legacy machine" they would not work on it, .. so should I push them?
Well, I personally think that's ridiculous, I'd Push them, I'd call AppleCare & talk up the chain if need be... there the ones that have or should have that Disc... man o man... Personally I'll never visit an Apple Store again in my lifetime, maybe try an independent AASP if none of that helps!..

Random shutdown problem on G5 dual 2.3 GHz w/OS 10.4.7

Hello,
I’m using a dual 2.3 GHz G5, and it’s been working flawlessly since I bought it about a year ago. Until yesterday, I was running OS 10.4.5. Yesterday I upgraded to 10.4.7, and as soon as I booted up after the install, I started having a maddening problem with my computer randomly shutting down. (Not sleeping, but a complete power down.)
At first, the shutdown would happen immediately after powering up; my computer wouldn’t even make it to the blue progress bar. I zapped the PRAM and tried something I found online about unplugging the computer for 15 seconds, then plugging it back in. It now boots up, and I can log in, but the computer still shuts down randomly.
There seems to be no pattern to the shutdowns. I tried taxing the processor by opening and resampling huge Photoshop files while lots of other apps were open, and things were fine. Then it would conk out while I was composing an email.
I’ve heard of this random shutdown problem affecting Macbooks, but I have yet to find anything about G5 towers and OS 10.4.7. Does anyone have any info/advice?
Many thanks.
G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD
G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD

Thanks for the advice. I did check the system.log in Console and found the following altert:
PMU FORCED SHUTDOWN, CAUSE = -122
Now, since my computer is just over a year old, and since this problem happened immediately after applying the 10.4.7 OS update, I found it hard to believe that my hardware could be responsible. After 2 days of troubleshooting, I was stumped; after a 2-hour service call, so was Apple tech support. I ended up doing an archive and install back down to 10.4.5, and all is well.
I tested this issue on other machines running 10.4.7 and had no problems. It seems that the following specific combination of elements triggered the problem:
• PowerMac G5 dual 2.3 GHz (dual 1.8 machines did not exhibit the same problem)
• OS 10.4.7
• Logging in with Open Directory/Active Directory mobile profiles
• iTunes 7
Bottom line: if you’re using a dual 2.3 GHz PowerMac with mobile OD/AD profiles, do not update to 10.4.7, and steer clear of iTunes 7, at least until there is a patch update available.
(And Apple wants to be taken seriously in the enterprise market?)
G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD

POWER PC G5 DUAL 2.5 GHZ FREEZING EVERYTIME THE FINDER OPENS.

I HAD TROUBLE SINCE THE VERY BEGINNING.
I HAVE A DUAL 2.5 GHZ G5 WITH 7 GB RAM. I THOUGHT IT WOULD BE A FLAWLESS INSTALL SINCE I HAVE A TOTAL OF 2.6 TB STORAGE. INSTEAD IT HAS BEEN A TOTAL NIGHTMARE, SLEEPLESS NIGHT WITH A CRASH-FREEZE AFTER FREEZE. I DID EVERYTHING POSSIBLE ERASE PRAM, TRY TO OPEN W/O XTENSIONS (DID NOT EVEN START THAT WAY) REINSTALL WITH ARCHIVE, INSTALL IN A SECOND HARD DRIVE OF MY FIVE ONES. NOW I AM A LITTLE DESPERATE . I SPOKE OVER AN HOUR TO APPLE SUPPORT. THEY RECOMMENDED THE INSTALL/ARCHIVE, AND GAVE ME A CASE # TO CALL BACK, IN CASE WOULD NOT WORK, WELL IT DID NOT WORK AND I HAD TO COME TO WORK. I NEED HELP.
THANKS

Me too! Dual 2Ghz with 3mb ram & multiple drives. I got 10.5 working - went well for about a week with occasional problems - keyboard keys sticking, occassionally hanging (have to shut down & startup using power key). Purchased a new keyboard thinking this was the difficulty + using bluetooth mighty mouse. Upgraded to 10.5.1 - experienced increased hangs. Zapped parameter ram (System started up on failed install on 2nd disk - grey screen of death - so inserted Leopard install disk, did permissions and disk check, chose startup disk - hung on choice. Since then have had repeated increasing slowness of system getting stuck on spotlight indexing which is highly variable - taking from 5 mins to 12hours to complete, meanwhile unable to open programmes. Occasionally able to open Mail but hangs, unable to force quit anything. Have tried to clear system by running chron, cleaning caches etc all to no avail. Tried reinstalling 10.5 (Archive & install)-hung in process, so now restore system from backup to 2nd disk with system on it, hangs at restart.
Now going to try shut down via power button again & see what happens. Failing this I'll do a erase and install (or try) - been trying to avoid this as a lot of very important work on the drive in question, had put faith in Backup & time machine so should be on third backup disk but as I can't access this have no way of knowing. Also heaps of software to reinstall! Frustrated as for the last 4 days have spent almost entire time trying to get computer running rather than doing work. This is costing me lots. Left with the conclusion if this doesn't work I'll have no choice but to purchase new computer in order to complete work.
Desperate for any assistance anyone could render. - Disks check out fine both using HD utility fsck etc.
Very interested in any progress you have on this via apple.
Cheers

Dual G5 2 GHz, random freezing for about one year now...

Hi Everybody
I own a Dual G5 2 GHz for about three years now. I used to work perfectly until about one year ago.
Then, presumably, an external FireWire harddisk blew the Logic Board. I had to have it replaced for a lot of money (because the G5 was out of warranty already). Since that point in time, the machine randomly freezes from time to time. And it is getting worse.
I tried a lot already, I think: RAM, USB peripherials (Mouse, Keyboard), removed all external things (but wireless, mouse, keyboard and screen), different screen, different keyboard... I had it turned in to different apple repair-centres twice and got it back with "no problem found" (although it froze in one case as well!).
Apple Hardware-Test runs fine. It gave an error that pointed to the Logic-Board or processor (according to Apple customer care) once, but this is not reproducible...
I am at a loss. What else can I do? By the way: the most "promising" thing to create the freeze (although there is no "definitive" way to do so) is to browse iTunes-Shop/Podcasts.
I would be very grateful for any hint/option. Thinking about Firmware update right now, but first have to check what verison I already have to see if there is a newer one.
Regards
andreas
Dual G5 Mac OS X (10.4)

Mozilla recently released Firefox 2.0, you may want
to give that a try.
I was thinking about that too. I might do this, if no crashes occur as long as I only use Safari (I can live with that for a week, np).
It's possible that there may be something else
running in the background (another application that
you installed perhaps) that could be causing the lock
up. Take a look at Activity Monitor
(/Applications/Utilities)
I'll have a look, but I don't think (hope?) there is something I missed...
Something else to look at would be to do a fresh
install (even if it's using an external FW drive),
reinstall your software 1 by 1 and see if it casuses
your machine to freeze. It's time consuming, but may
help in narrowing down what is the cause (if in fact
it is software related).
Two points here: first is that I cannot reinstall one by one because the error is not (yet) reprocucible. So I would never know when one app is "secure" and when to install the next one...
And second, I think that software should no be able to freeze a system like OS X (or FreeBSD) just like that, no? Maybe crash the app, but not the system...
Also, are you running any Classic applications?
Nope.
If you don't already have the newest version of
Firefox installed, try that first and see what
happens.
I have And I had a lot of different versions throughout the last year
Thanks for your input, Ben, I appreciate it!

PowerMac G5 Dual 2.5 Ghz. Want Start PLEASE HELP ME!!!

HI, all
I have MacPro G5 Dual 2.5 Ghz. 2004 PCI-X Bus
Yesterday my mac freeze during normal operation in Leopard 10.5.8
When I tried to restart the computer stop after display Apple Logo in the startup.
I have tried all this features:
1) Start from CD Same.
2) Reset SMU With Power Switch in the mani Board Same.
3) Reset Pram In some case the computer freeze and it's doesn't do that, in some other the Pram is reset but the machine still doesn't start.
4) Replace Pram Battery 3.6 V Same.
5) Start With Open Firmware (Altcommand+of) When i write "reset-all" The machine Freeze.
6) Start with Hardware test CD And IT Work Fine, all tests are passed with OK in base and exaust test!!!!!
7) At last I have replace the video Card, but same freeze at start.
I have tried to swap display using second monitor out And I have seen some strange things:
When I use second display connector the computer still freeze during the startup sequence after the apple logo, but when i shut off computer pressing 10 second the power switch and reconnect the first display connector the machine start normal al all work fine (INCREDIBLE!!)
But when I shutdown the computer the next time i try to power on it freeze in the same way!!!
Just for information if i start in verbose mode (command+v) the machine freeze after "DART Enable"
Please anyone could help me to resolve this issue?
Thank's In Advance and sorry for my bad english.
Bye

Hi, I have Dual 2.0 GHz machine and it has some of the symptoms yours has. In Open Firmware if I type reset-nvram, set-defaults and then reset-all the computer does freeze, but in my case if I type reset-all without those two the computer resets itself as it is supposed to do.
My computer usually hangs at the apple logo and verbose mode shows DART Enabled as last message, rarely it will not chime at all or will chime but so no picture. If sometimes boots fine and runs without problems for 15 seconds to 3 hours, in my case it seems that if I run the CPU's at maximum settings and put them to constant stress the system is more stable, which I think is odd.
I have replace PRAM battery but that did not change the situation. I will later try to reseat or remove one of the processors altough I don't know if these motherboards are designed to work with processors removed.
I think it is motherboard or CPU -issue.

Flash 8 Pro freezes on Mac G5, dual 2,5 GHz

Ever since I upgraded from Flash MX 2004 Professional to
Flash Professional 8 on my PowerMac G5 it doesn't run. All I can do
is
open the software but as soon as I click on a menu or a
button, whatever, like changing the size it freezes instantly. I've
searched the forum and every possible place to find any answer that
can solve my problem but it seems like I'm alone with this, I can't
find any information anywhere. I've even tried to un-install and
re-install Flash again but same problem still occur - freezing. Has
anyone had the same problem on a Mac G5 with dual 2,5 GHz
processors, in that case – what did you do to solve the
problem? I'm out of ideas and can't figure out more.
My specs are:
PowerMac G5 (2005), dual 2,5 GHz processors
Boot ROM-version: 5.1.8f7
Systemversion: Mac OS X 10.3.9
Kernel-version: Darwin 7.9.0
1 GB RAM memory
Apple 20" flatscreen, 1650 x 1050 pixles resolution
Flash Professional 8, upgrade (Flash worked fine before the
upgrade!)
All other Studio softwares I upgraded run and work great,
except for Flash.
Please help me, I need HELP!

I also have to add: I can't even click on Preferences in
Flash, nothing. It freezes instantly. It run as long as I don't
touch ANY button or menu in Flash, as soon as I do anything, touch
a menu or button Flash freeze.
Anyone know what to do? Or shall I throw it out and install
an earlier version like MX 2004 Professional, that version of Flash
worked. Please, please, please... Help.

Dual 1.8 GHz G5 only running of one processor

My dad has a Dual 1.8 GHz G5 and had problems in the past, one of the processors went out. He took it to a repair shop and they switched it to run only off one processor. Apparently after they repaired the computer, they didn't tell it to run on both processors. We found out when we went to About this Mac. How do I tell it to run off both processors again?
G5 Dual 2.7 GHz, 15-inch PowerBook 1.5 GHz Mac OS X (10.4.3)

Nap is a power saving feature.
The following processor states are defined:
■ Run: The system is running at maximum processing capacity with the processor running at full speed.
■ Idle: The system is idling; this is the default state. All clocks are running and the system can return to running code within a few nanoseconds. If the system has no work to do, it will be in idle mode.
From idle, the processor will enter deep nap state when the system is power-stepped to half frequency. In this state, the processor’s internal frequency is reduced to 1/64 of the maximum frequency. The processor frequency is returned to normal on exit from idle. The exit from idle takes a bit longer than the regular idle nap but is still in the nanoseconds.

HT1349 I have a Power PC G5 mac. It's Dual 1.8 GHz and has 1 GB DDR SD Ram. This mac has no wireless Airport Card. Where do I get one to install in the computer so that it is able to pick up wifi signal and how much is the cost?

I have an older Power PC G5 desktop mac. It has 1GB DDR and SD Ram and Dual 1.8 GHz. The problem is there is no wifi signal. I think I need an airport card to insert in order for this model to pick up wifi. How do I know which airport card to use?

Your Power Mac G5 had an option to have an 802.11b/g AirPort Extreme Card. You basically have two choices: 1) Search the Internet for vendors that still provide this card, or 2) Get a wireless USB adapter that supports both 802.11b/g, but also the newer 802.11n standard. An example of this USB adapter can be found here.

G5 Dual 1.8 GHz fans gradually go to full speed and stay there

My G5 Dual 1.8 GHz boots normally and quietly, with no freezes or panics. However, within a minute or so, I hear the fans begin to gradually gain speed. This continues for a couple of minutes until the fans reach maximum speed, making my room sound like a wind tunnel. This occurs with no programs running, just sitting idle at the Finder desktop.
I've checked the CPU & system temperatures using the shareware utility "Temperature Monitor 2.5" and everything is running cool, barely above room ambient, so there is no thermal reason for the fans to "take-off" like this as the heat pipes are doing their jobs to cool the CPUs.
There is no restriction on air flow around the case, and the acrylic side panel is installed. Interestingly, removing the side panel seems to have no effect on fan speed, whether installed or not ... maybe it's just the liquid cooled G5s, but isn't removing the side panel suppose to force the fans to full speed?
I was wondering if this out of control fan speed is a known issue that can be resolved with either a firmware update or software patch? Does this indicate the need for a thermal recalibration?

I've since answered my own question on this ... The reseller had installed OSX 10.3.2 as the boot OS. The (Late 2004) DP 1.8 GHz G5 requires 10.3.5 minimum, and with that update, the problem went away. The G5 now runs quietly.
This was far simpler than I had expected. Thanks.

I use a 2003 FW800 MDD desktop, with dual 1.25 GHz processors, and OS10.4.11, and with native Bluetooth card, won't recognize a newer Bluetooth Headphone set as an Input or Output device in System Preferences

I use a Mac 2003 FW800 MDD desktop with dual 1.25 GHz processors, 2 GB memory, and a native Bluetooth card installed. I use OS10.4.11. The FW800 was the only MDD that could use Bluetooth natively, as an optional installation. I use the installed Bluetooth to run an Apple Aluminum Keyboard, and would like to use it with a new (2010) Samsung SBH-600 Bluetooth Headphone set, but, although the set will pair with the computer, and is recognized in both the System Profiler, and the Bluetooth section of System Preferences, it is not recognized in the Sound preferences section of System Preferences as either an Input or Output device. Only the installed external Apple speakers are recognized. I'd like to know if there is anything that can be done to make the Bluetooth system installed work with these headphones - either something that can be changed in the computer settings, or an added external Bluetooth device with different Bluetooth capabilities.

It it may be that you are running either an outdated BT software or the firmware of the card is not up to date.
What version is your BT software? Is it later than 1.5?
http://support.apple.com/kb/DL1209
Firmware:
http://support.apple.com/kb/DL354
Along with the firmware, it is likely that the headphones require a later BT revision than you are running. The headphones need rev.2.
You may need to move to Leopard for support.
http://support.apple.com/kb/DL889
It also may be that headphone support is limited to iChat or the like in Tiger.....
If you go to a USB BT dongle, D-Link often gets the nod as having native compatibility in OS X.

G5 dual 2.7 GHz. Cannot initial hard drive... HELP Please

Just put a new hard drive into the machine today as a second drive. I now have 2 drives installed.
Drive 1 - Western Digital WDC WD2500JD-41HBC0. 250 Gig. Partitioned as 40 Gig for Apps and 190 Gig for storage. This drive came preinstalled on system
Drive 2 - Western Digital WDC WD2500. 250 Gig
I put the drive into the system and initialized it with no problems.
I was working in Final Cut Pro (4.5) and using the new drive as my capture drive. FCP stopped responding during a capture. When this happens it always fills up whatever room is remaining on the capture drive with a temp file. very annoying actually.
Anyway, I had to restart the system and zapped the PRAM. Now when it finishes booting up, I get told that the new drive that I inserted is not initialized. Problem is, when I go to initialize the drive, I can't. Disk Utility will not let me do anything with the drive at all.
When I open Disk Utility and click on the new drive, at the bottom of the window where the drive info is, I get told that the Total Capacity is 0 bytes
When I attempt to erase the drive, I tell it I want Mac OS Standard, give it a one word name and tell it to begin. I get a message saying 'Disk Erase failed' with the following error.... 'The chosen size is not valid for the chosen file system'
If I try to partition the drive, I get an error message saying that the device is not configured.
I have tried running Disk Utility in Safe mode as well as booting from the install Disk.
How can I get this drive back? I don't care about the info on the drive, I just need the drive itself to work.
G5 dual 2.7 GHz. Mac OS X (10.4.4) 1.5 GB RAM

Sorry I don't have an immediate solution for you, but thought someone should pipe in.
The same thing happened to me years ago on G4 drive installed on an Apple supplied SCSI card. The only way I could get it working was to boot into OS9 format it (probably zeroing out all data). I then reformatted successfully in OSX. HOWEVER... I never stopped having probs with my scsi drives - finally thru out 2 very pricey ones.
The moral of the story: was that the problem was in the bus/software to the drive. This may not have anything to do with your issue.
Obviously you can't boot into 9, but there are 2 possible problems (other than a dead drive or bad cabling) that I'd look into:
1. OWC sent me some instructions with a drive for my G5 about messing with jumpers (based on whether or not drives were set up as master or slaves). You might look these up at OWC (macsales.com).
2. It's possible that the WD drive you have has the same SSC issue discussed on these boards like the Seagate drive -- try a search for Seagate, or just browse all threads relating to HDs.
Good luck - please let us know if you find a solution.

G5 Dual 2.0 Ghz (2003). Light blinks 3 times

Hi there: I have a big problem on my G5. It's impossbile to turn it on because the power light blinks for 3 times. I have the following configuration: G5 dual 2.0 Ghz (2003) and 2x256 + 2x512 MB of ram. I looked for posts in this forum, and I saw that this event occured to other people. Following some suggestions, I removed all USB and Firewire devices, removed all the ram, cleaned the RAM modules, installed only the 2x256 and tried a boot. Then I removed 2x256 and installed 2x512, but results are the same. I also reset the PMU/SMU through the button on G5 motherboard... but nothing. Manual says that a 3 time blinking light means RAM not supported, but considering that my G5 had been working for 3 years till yesterday and nothig was added or changed... it sounds very strange. Could it be possible that both ram (256 and 512) are broken?
I thank in advance everyone who can help me.

I will tell you this, if Apple doesn't cover this problem my 15 years of loyalty with over 15+ computers will come to a halt and I will switch to PC. They made it clear so far that they will not cover this. We ar talking about the early production run of this model. Do a Google and search for "G5 logic boards for sale. You will find the phrase "2nd generation or revised version, etc. etc". Why? because there was a major issue with initial runs of this computer and a faulty logic board/power issue that is being ignored. My computer, only 3 or 4 years old is dead. Nothing but 3 blinking lights, a pause, then 3 blinking lights. This points to ram but the ram is fine. Its the board that the ram snaps into thats causing the problem (confirmed by Apple). Why should I pay for a KNOWN QUALITY ISSUE with these machines? At least cover the part. Come on $1000 for a logic board after 3-4 years? How could this be "my problem" when the other dozen or so computers I've owned rarely had any hardware issues? If Apple takes down these posts then they choose to ignore the situation. I have enough experience with computers to know when one is a lemon. Yes, from day one this computer had issues from crashes, freezes, to high speed fan noises. The high speed fan noises continued (even after the initial firmware upgrade) because the computer is getting a signal to cool things down at inapropriate times (like sleep mode)....after a usual episode the computer usually freezes and has to be manually re-booted which can't be a good thing over the long haul. Anyhow, sorry for the whinning but I feel that the company i had faith in in the past is now letting me down. If this situation changes, I promise to post it, but it doesn't look good at this point. Good luck to you and the many others who have or will have a stong possiblity of future issues with this particular model.

What is the latest OS I can use with a mac G5 with a dual 2.3 Ghz PowerPC G5 processor?

What is the latest OS I can use with a mac G5 with a dual 2.3 Ghz PowerPC G5 processor? Everything on my computer has been running so slowly in the last few weeks. Have I finally outgrown OS 10.4.11? Would there be some other problem that would sudden make all my speed take a nose dive? I have 8.5 gigs of RAM... Please advise!
Thanks! Matthew

Everything on my computer has been running so slowly in the last few weeks.
First open Console in Applications>Utilities, see if you have reapeating messages.
How much Free Space do you have on the Hard Drive?
At this point I think you should get Applejack...

After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

Dual 2.3 GHz G5 suddenly shutting down

We have a Dual 2.3 GHz G5 (production week 10/29/05, Power PPC 970 v.3.0, with 2.5 GHz RAM), running OS 10.4.8. This machine has started to suddenly shut down - like someone pulled the plug with no warning.
After turning itself off like that, we need to wait around 20 minutes before it'll start up again and keep running. Once it has shut itself off, we cannot get to the logon screen without it shutting off suddenly again. After letting it cool down for 20 minutes, it'll run again. So it seems to be heat related in some way.
I've run Temperature Monitor and iStat, and everything looks OK. Of course TechTool Deluxe didn't find anything (does it ever?).
The machine will run for 2-3 hours under load just fine, but will suddenly click and shut off at some point - even when not under a load.
I've checked the System logs and Console logs and can see nothing, except once the system log reported "ApplePMU::PMU forced shutdown, cause = -122"
The other times there was no log entry, like it shut down too fast for the log to be written.
Is the power supply going bad? Is there a temperature sensor which is too sensitive?
We'd appreciate any help or suggestions.

o maybe there is something RAM related, but I can't
imagine that RAM would shut the machine completely
off. Can it?
I believe the problem is thermal related. You may have a processor acting up. Try running Hardware Monitor once, and see what your internal temps are running.
