Power Mac G4 MDD Drive Carriers

Where can I obtain a rear drive carrier for a Power Mac G4 MDD (Mirrored Drive Door)? Mine happens to be a Firewire 800 model, but I believe this piece should be the same as the other MDD Macs. I have not been able to find any information about this on Apple's site, or the popular Mac Support sites that I'm aware of.
Even a part number would be a help at this point.
Thanks!

The part number is 922-5290, same carrier fits in both front and back, I would try ebay, some sites like this one are pretty **** pricey http://www.welovemacs.com/9225290.html, try google see what that comes up with.

My Power Mac G4 MDD has no DVD drive how do I pair it install OS X on my new HD.

My Power Mac G4 MDD has no DVD drive how do I pair it install OS X on my new HD.

Hi, two ways...
Put the Install Disc in another Mac tathas Firewire, put the other Mac into Target mode...
http://support.apple.com/kb/HT1661
This turns the other Mac into a big Firewire DVD drive, then boot the MDD holding the Option Key, select the Install Disc in the other Mac to boot the MDD from.
Or an external FW DVD...

Power Mac G4 MDD power supply unit/RAM

Hello,
I just bought a used Power Mac G4 (Mirrored Drive Doors) at a garage sale for $20. The owner said it works, but he took out the RAM, power supply unit and hard drive.
I would like to place an order for the RAM and power supply unit but I am not sure how I differentiate which power supply unit to purchase. When I try to look it up all I find it is that it had gods gift to worst ever power supply unit in the history of power supply units. It was the loudest most obnoxious fan set up or something of the sort.
Well bottom line I need to get a few replacement parts for the old G4 desktop and was hoping that some experienced mac hardware person could point me in the right direction. I am comfortable replacing parts I am just not certain what I need to purchase to install.
Does anybody know of any good 3rd party hardware that they could suggest for a replacement part?
Power Mac G4
Designed by Apple in California
Model No.: M8570 EMC No.:1914
Thank you very much :]
(I am pretty sure I posted this in the right subcategory, sorry if I did not.)
None of these model numbers match, but it everything I research says it was from this generation of G4’s. How can I 100% tell which one is the model I have?

I just finished rebuilding my MDD (FW800). As for finding specific parts for your machine, be sure you have the model number, or are able to differentiate between the models. That being said, most of the case parts are interchangeable. Problems can occur when swapping processors and failing to use the proper heat sink for that processor.
The best place (price wise versus availability) that I've found for MDD power supplies is on eBay. However, be aware that you will probably be getting it used. So either ask the seller if they will guarantee it for a specified period of time, or buy it from a seller that offers a guarantee (normally 30 days). If you get one that lasts for 30 days without any problems you've probably got a good one. Price is normally around $140 + shipping.
Another avenue is to try shopping the web (Google) for what you need. There are a number of great websites that carry what you may need, or maybe are looking for. Some of those to checkout are:
www.applecomponents.com
www.otherworldcomputing.com
xlr8yourmac.com
www.lowendmac.com
Additionally there are a number of case and power supply mods that can be done to quiet down the MDD. Apple doesn't necessarily endorse these mods, as they deal with changing power supply cooling fans, and/or the processor/case cooling fans. However, if your MDD is out of warranty, you practice safe electrical/static work practices as you're working, and you're willing to accept any negative consequences should those mods either not work properly or they happen to result in damage to other components, then do what you feel is appropriate.
As for telling exactly which model you have, and how it was originally configured when it shipped from Apple, research the serial number through this Apple website. Another way is to check the model number of the motherboard. This is located near the PCI slots, by the modem connection. It will have a number something like 820-1453-A, or 820-1500-A. Cross referencing these through Google can help tell which motherboard you have. As for the processor, you'll need to carefully remove the heartsink (5 screws) and look at the chip(s) itself. If there are two chips it's a dual processor, and if only one it's a single (Duh!). Then locate the small white sticker that's stuck to the processor card for the processor's info. It should tell you what you need to know about it. You can also look at the info inscribed on the face of each processor chip.
Important Note: Be very careful, and wear a grounding wristband at all times when when working on the inside, or handling any computer components. This is particularly true when handling the processor card, and here's why. Any static shock from you to the motherboard or to the processor could severely damage or destroy that component.
Here's another link to way of quieting the MDD.

Anyway, I hope these help you find what you need. Be careful!!

Apple Mouse not working on Power Mac G4 MDD, works on other computers

I cannot get my standard Apple optical USB mouse to work properly with my Power Mac G4 (MDD). When I plug it in, the lights on the mouse work but the cursor does not respond. No movement, no clicking. However, when I plug the mouse into another one of my Macs, it works fine.
The Power Mac's System Profiler recognizes it as "USB Device," the mouse is unresponsive, and there are no mouse options in the System Prefs (keyboard & mouse). My Power Book's System Profiler recognizes it as "Apple Optical USB Mouse" and it works perfectly.
I am running 10.4.6 on both machines but I have had the problem with multiple versions from 10.3 up. I also bought another USB mouse (a Kensington) and had the same issues.
I've run through the standard USB troubleshooting like trying devices one-at-a-time and trying each USB port (on the Power Mac, the keyboard, and the back of a Cinema Display) as described in KB #300543 and KB #58033 but to no avail.
One thing that did stand out in #58033:
If the device shows up in System Profiler, even if the device doesn't work, the issue is usually due to software. Your best solution is to try updating the drivers, creating a new user, or reinstalling the system software.
Is there any way to update an Apple driver? I've only seen software for 3rd-party mouse drivers. I would try to create a new user but it doesn't seem to be possible using only keyboard shortcuts. And I would like to avoid reinstalling the system software!
Thanks for reading.
Power Mac G4 (MDD) Mac OS X (10.4.6)

Have you tried other mice on your computer?
I seem to recall a problem like this when Speakable Items is turned on. I'm also going to dig into a little research on this.
Try checking that out. Make sure it is off.
The other things to try are logging in as another user and see if the problem remains. If so, there is a bad preference in your user preferences.
Lastly, if all else fails, try downloading USB Overdrive and see if it takes over the mouse function and provides you with a usable mouse.

Power Mac G4 MDD won't wake from sleep mode

I have a Power Mac G4 MDD 1.25GHz with a 15" Apple display and running 10.4.
I can not wake the computer up from the sleep mode. It will not respond to the mouse moving, a mouse click, a keyboard key, the power button on the display or the power button on the computer.
The only thing I can do is force the computer off by holding in the power button (on display or computer) and restarting the computer.
The computer is set to go to sleep after 1 hour of no use (or the issue happens if I put it to sleep).
Any thoughts would be great.

This is for a Mac that won't sleep.
Here is KB article HT1776 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
Also, here is Apple doc.#305262 about PCI cards and sleep.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Tristan Currier noticed this; "I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
Check the printer queue!"
Good Luck!  DALE

Power Mac G4 MDD with 1.5 GB RAM slows to a crawl

My Power Mac G4 MDD has been getting slower and slower for the past couple of years, and now it takes forever to do a lot of things that it did quickly before. Today it even told me it didn't have enough RAM available to open Photoshop, even though I only had maybe three other apps open and I have 1.5 GB of RAM.
I had originally suspected the hard drive was fragmented, and I ran Disk Utilities on it, but that didn't help. Maybe I need a better disk utility? Also, the RAM message I got today leads me to believe it could be memory related.
Wat's going on and how do I fix it?

Hi
I'd start by checking the basics if you haven't already.
If you run the Activity Monitor application located in the Applications -> Utilities folder and click on the System Memory tab you can monitor the memory usage as you use your applications. You can use it to check the full 1.5GB is still being recognized and see how much you have free at any time. The following article helps explain the memory usage shown:
http://docs.info.apple.com/article.html?artnum=107918
If you click on the Disk Usage tab you can also monitor the disk space usage and see how much you still have free. Although the message refers to RAM, it may be as a side affect of not having enough free disk space for the virtual memory. I'd always make sure you have at least 5GB of disk space free for the OS temporary files and virtual memory use etc.
Finally it may be worth running the OS X maintenance scripts. These would normally get run in the small hours of the morning assuming the computer is still switched on and not asleep. However, they can also be run manually at any time, either from the command line using Terminal or from a third party front end such as MacJanitor. More information can be found here:

Power Mac G4 MDD Random Power Shut Down

I am located in Thailand and have a Power Mac G4 purchased in November 2003. Last month the computer shut-down at random times and during various types of operations. CPU and hard drive temperatures were well within range, the installed battery tested at 3.5 volts. A new UPS was purchased with surge protection, no software was provided or appeared necessary. Often times the computer would re-start if I let it set for 30 minutes or more. Sometimes if the power plug was removed and re-inserted or the UPS re-set, the computer would start.
Associated hardware consists of Canon Printer, Mac keyboard, Kensington turbo ball, stand alone backup hard disk, flash card reader, ViewSonic moniter (8 to 10 years old), flash card reader, USB hub and audio system. Am connected to the internet via a router with one other computers on the line.
The problem has occurred with and without the attached hardware except for the monitor, keyboard and turbo ball which had to be attached to operate. The keyboard, turbo ball and computer where serviced by local Apple service center. The keyboard and turbo ball checked out OK. After sever attempts since the shutdowns were random and could not be forced, the service center after much testing and waiting decided the logic board need replacement which was done (400+ USD). A new power supply was ordered but they stated it did not need replacement.
Since the new logic board was installed and run for three days with no problem, the computer was returned with 90 day warranty. The problem almost immediately returned but has run OK for long periods of time before a random shut-down occurs. The shop was contacted and we are continuing to observe the problem but I hate to give up the use of my only computer for another month, like the last repair.
The following chart is a play by play account since the repairs.
The shop and I are completely stumped and any comments would be appreciated
*Power Mac G4 MDD Random Shut-down Problem*
Note 1: shut-down is same as pulling the power plug.
Note 2: below is complete list of events, on dates not shown, computer working normally.
DATE TIME EVENT
May 9, 2008 noon Picked up computer from Phuket Alpha after replacing logic board and
complete check-out. (Power supply not replaced)
May 9, 2008 evening Shut-down several times, could re-start a couple of times and then shut-
down and could not re-start.
May 10, 2008 all day Computer working OK.
May 17, 2008 5:34 AM Shut-down.
Turned off UPS, turned on UPS and computer started by itself without using
Mac start button.
Shut-down minutes later, would not re-start using any method i.e., re-set
UPS, pull-out power plug etc.
May 18, 2008 noon Turned on computer, OK.
May 19, 2008 1:30 AM Selected sleep from Apple drop down menu, computer shut-down.
May 19, 2008 4:30 AM Turned off UPS, turned on UPS and pressed start button on computer, started OK.
May 19, 2008 1 hr later Shut-down while using Safari
May 19, 2008 evening Started computer OK, then placed in sleep mode.
May 19, 2008 8:00 PM Pressed space bar to wake-up Mac, computer immediately shut-down and
UPS alarm came on. Re-set UPS and computer came on with high-speed
sound of (fan or hard-drive) which ran for several minutes (estimate at
least 5). Computer then worked OK for many hours.
May 22, 2008 6:30 AM After using all night, computer shut-down while using Safari.
May 22, 2008 1:00 PM Pressed Mac start button and computer operating OK.

Hi-
Welcome to Discussions!
Replace the power cord. If this doesn't alleviate the condition, (from your description) I would consider the PSU to be the most likely suspect.

Power mac g4 MDD doesn't recognize any CD when booting with C depressed

Hi, I purchased this Power Mac Mirror Door Drive about a month ago on e-Bay. It came with OS 10.4.8 installed, no CD's for OS 10 and a CD with an Orange 9 containing OS 9.2.1. OS 9 was not installed on the machine. I have PhotoShop and Quark that require OS 9. I have tried to follow all your discussions on installing OS 9, keeping OS 10.4.8 intact, but so far this machine will not recognize any bootable CD. The best I've gotten so far is the machine placed one of the attempts on the desk top as an empty CD. I have tried to boot holding down the C key, booted in safe mode, have tried bootable OS 10.2.1 CD's, have tried bootable Software restore CD's (set of four CD's) with OS 9.2.2, Power Mac G4 OS 9.2.2 Install CD, eMac OS 9 Install CD, iMac OS 9 Install, all Gray Labels. So far nothing works. I live on a lake in TN and if this thing wasn't so expensive it would have been a boat anchor by now. I don't have any way to reload OS 10.4.8 or I would try to reformat one of the hard drives and start over. Apple told me that I need the same disks that were shipped with the machine and that they would cost me $180 delivered to my home. But that puts me back to OS 10.2.1 and then I would have to purchase OS 10.4.8 again. How can I get Classic to load on this machine? The CD drive will load a music CD, or a DVD, or a blank CD-R just fine.
Thanks,
Tony

Tony,
The set of 6 restore CD's certainly sound like they're from the right era. The part numbers are very close to those for my MDD, which was on sale at the same time as your dual 867MHz. I have varying numbers from 691-3545-A to 691-3548-A, 691-3600-A (for restore CD 4). The two OSX install CD's come with 691-3956-A and 691-4081-A. All my CD part no's are prefixed with Z, for International English.
Unfortunately the MDD's (at the time of your dual 867MHz MDD and my dual 1GHz MDD came with 4 restore CD's and two OSX install CD's. To get OS9 installed, it would need to be the right restore CD for the Mac.
Unless you're up for a bit of trickery. At no cost. All you need to be able to do is use the three Unix commands "cp", "ls" and "cd".
With the Mac booted up into OSX, open up a Terminal session, make the window bigger if you want. Insert the first PMG4 restore cd.
In Terminal:
Go to the /Volumes directory (cd /Volumes).
List the directories found there (ls -la)
Two will be the internal disks (20G and 60G if I remember). One will be for the Restore cd (probably called "Restore CD" or something.
go into the "Restore CD" directory. (cd Restore*) Note, if you try 'cd Restore CD', it will error, you would need double-quotes round a directory name with spaces in it, ie. cd "Restore CD".
List the directory contents (ls -la)
In there is a '.images' directory, which contains disk images, including one of OS9. You can't see this folder in the Finder.
Go into the .images directory (cd .images)
List the directory contents (ls -la)
There should be an OS9General.dmg disk image.
You will need to copy this to a directory that you can read (cp OS9* ~/).
It's a 300MB+ file, being copied from cd, so it may take 4-5 minutes.
Now in the Finder:
Go to your home directory.
There should be an OS9General.dmg disk image there. You can mount this.
It should have (fingers crossed) a usable OS9 System Folder (and OS9 Applications Folder) that you can use. Copy it to your startup disk. You may have to play around with the System/Finder to get the folder blessed. Then see if you can select it in the OSX Startup Disk system pref. Try a reboot if you feel brave.
I would go through all the other Restore CD's, just like above, looking for useful stuff you can install.
All this means nothing of course, if there are no OS9 drivers installed on the startup disk. But with two disks installed (and other Macs to hand) you should be able to reformat one of the disks (from within OSX) installing OS9 drivers.
Perhaps someone knows of a way to get OS9 drivers installed without having to reformat. I'm sure it can be done, but I have no experience of doing it.
Note, you're still left without an OS9 startup cd, but if all goes well, you're back in OS9. And there would be nothing to stop you putting an OS9 System Folder on each disk.
Let us know what you decide / do.

Power Mac G4 Mdd Hardware Advice

I was gifted a Power Mac G4 MDD that had been taken out by a power surge due to lightning.
The power supply was bad. Installed a new one. Didn't get a hard drive. Had a OK pc one that is partitioned
and formatted fat32. Have 10.2.8 OSX install cd's and Norton Utilities cd for 10.2 and older. Does not seem
to want to boot from them. It will boot to open firmware. Otherwise it just shows the finder face flashing
to a question mark then back. Have done the remove battery and CUDA thing. Did the reset-nvram, set-default,
reset-all,zapped pram, checked ram in a pc then replaced, removed processor board and reseated,
tried using a pc cdrom. Nowjust wondering if it's the logic board or the board with the processors?
Any help would be greatly appreciated.
Power Mac G4 MDD Model M8570 PMG 1.42dp Serial# xb3230mrn1y Logic Board 630-4633 Processor board

Is the CD disc a full retail copy with either a white background with furry looking X or is the disc a gray colored disc?
If gray disc, does it say anything about Apple PowerMac restore discs?
Gray restore discs are Mac-machine specific and if it is for a PowerMac G4, it may or may not be the right restore discs for that model PowerMac.
Also, It wouldn't hurt to either find a known working external optical to borrow or purchase an external optical drive to try and boot the disc from to confirm whether or not the PowerMac's internal optical drive is working or not.
If you have to purchase an optical drive, I recomend this website and this drive.

Power Mac G4 MDD Intermittent Boot from Internal HD?

I have a Power Mac G4 MDD with a 1.42G Dual Processor, 2GB Ram using a 500GB HD operating OS 10.5.8 The problem I am having is that my computer will boot just fine for a week or so then all of a sudden it won’t boot up at all from the internal HD. Here are the symptoms; I get the ‘chime’, then the grey screen appears with the black apple logo and I see the ‘spinning gear’. The spinning gear stops (after about 15 secs) then it goes to a light blue screen and just sits there forever. I usually see this ‘blue screen’ for about 2 seconds just before my desktop appears on the screen during a normal boot. I could go home tonight and it might boot up just fine, I don’t know, but it’s very frustrating. Things I have tried – ( I have two MDD’s so it’s pretty easy to troubleshoot) but still no successful boot sequence.
1. Reset PRAM
2. Changed MOB battery
3. Attempted a boot from another known good HD
4. Removed the 500 GB HD and installed in another MDD and it boots every time.
5. Replaced Motherboard with a known good spare I have.
6. Swapped out RAM modules
I’m not sure what’s next? Processor?, Power Supply??, Video Card??
Maybe someone out there has seen or witnessed this strange occurrence on their MDD?

I have not reseated ALL the connectors but I will try that first tonight. I removed the AC last night so when I get home I will power it up and try again. When I can get it to boot reliably, it's usually been following an AC outage overnight or a couple of days.
Thanks,

OS X 10.4.11 will send but not receive faxes on Power Mac G4 MDD

OS X 10.4.11 will send but not receive faxes on my Power Mac G4 MDD. Perhaps I should remove the relevant .plist preference file(s). But which one(s) is it /are they? Or is there something else I should do?

Thank you for your reply, BDAqua. I have set the fax feature to answer after 3 rings, but the phone rings only once when someone is trying to send a fax. The phone icon in the menu bar changes to "ringing ..." but nothing more happens. The phone line on which I receive faxes is dedicated to that use. I phoned in to its number earlier today from another phone. I heard it ring once and then it went to the busy signal. I then disconnected the fax phone line from its wall jack, connected a phone to the jack, and phoned in to it. The phone now rang and rang as it should. So this confirms the assumption that the fault is in the computer, presumably in the Print & Fax software. I should also mention that I don't find com.apple.print.FaxPrefs.plist in /Library/Preferences.

Power Mac G4 MDD problems with Hardware test Memory errors

I have been troubleshooting slowness and unexplained lockups on my Power Mac G4 MDD. I've had the system since 2002. I tried to run hardware test (the disk that came with my system), and I get an error message at startup:
Invalid Memory Access at %SRRO: 00034870
%SRR1: 00003030
I run mac-boot, and get another memory error
Invalid Memory Access at:
%SRRO: 056106dc
%SRR1: 00003030
Does this mean my memory has gone bad? I don't get any other screens for testing hardware.
The lockups are varied, but many seem to deal with Safari. I have also repaired disk permissions and repaired disk. I then get security error messages when I restart, and I choose to fix them, and things are fine for a while, but then it slows down some and starts locking up again.
Thanks for any suggestions,
Marbot61

Hi Marbot61,
You might be interested in the thread "error when booting from AHT CD" on this forum. Since four different users have had the same error message in two days, perhaps ram chips are actually ok, and there is something else going on with the AHT CD boot process.

I can not seem to configure my AirPort Card on my power mac G4 MDD desktop

I'm trying to configure my new airport card on my old power mac g4 MDD desktop. The image is not supported by AirPort Extreme.
Please advise… thank you in advance. Jose

What's the problem with configuration? In the top right hand corner of your desktop you will see the AirPort symbol. Can you see any WiFi networks there?
Or do you mean a new AirPort Extreme router? In that case you will need either:
1. A newer Mac
2. OS X Leopard
10.4.11 does not support the latest generation of Extremes.

Power Mac G4 MDD not getting past apple logo

Hey,
I was recently given an old Power Mac G4 MDD from my school. It had Leopard on it, and seemed to be running fine. However because the computer had school software, they told me i had to replace the os on it, and gave me the disks for OSX 10.2. After installing 10.2, I restarted my G4, however it did not get past the white screen with the grey apple logo. No spinning wheel either.
The computer has 2 harddrives, and 3x 256 Mb DDR Ram. I am unsure of the processor
Can anyone say what is wrong with this computer/How i might fix it?
Thanks in advance,
Angus

Here's the spec page on your Mac http://www.everymac.com/systems/apple/powermacg4/stats/powermac_g4_1.25mdd.html
It came with OS 10.2 installed.
I have an identical Mac. The gray Software Install and Restore disc has the P/N 691-4679-A & the OS is 10.2.7. You may have been given the wrong installer.

Power Mac G4 MDD: OS 9? Graphics? CDs?

Hi,
I've rediscovered my old Power Mac G4 MDD in my cellar - how can I find out
a) if it can boot OS 9 (native), and
b) what graphic card is installed as the system profiler displays "no info", the graphic card only states GeForce 4 on the cooler and none of the serial numbers written on it reveal any info in google
c) where I can get the original CDs that came with the system
Would be great to get some guideance.
Thanks in advance!
