Imac G5 wont boot ,tried to upgrade s.w

Tried to upgrade software to Leopard OSX 10.5.1 failed to complete,could not eject disc,tried to reboot and now I getlines of errors
IOUSBWirless controller device:family specific matching fails. OR
A grey start up screen with APPLE and timer running can anyone HELP!!!!!!

I think if the machine powers on it's not the battery.
Try this:
Try holding down the option key then power on. This brings up the startup manager. Click on your hd. Click on right arrow key.
If you get into the startup manager, I doubt it's the battery.
You need to have a valid cd/dvd to boot the machine. What are you trying to boot? What are the numbers on the cd/dvd or what is the picture? What color is the Dvd/cd?

IMac shuts down when trying to upgrade from Tiger to Leopard

My iMac, purchased in November of '07, came installed with Tiger but also came with a Leopard OS update disk. When trying to upgrade to Leopard last week, every time I rebooted off the disk the computer would run for a minute in the gray screen and then suddenly shut off with no warning message. I checked HD in disk utilities, repaired my permissions and tried again with the same results. I've got 30 gigs of free space and 4 gigs of RAM which should be plenty. I talked to Apple support who walked me through the installation procedure with the same results and ended up shipping me a new install disk which came today. I am getting the same shut down on reboot with their replacement disk. Apple actually sent me two white disks. The first is labeled "For Mac Computers, Mac OSX Install disc 1" The second is labeled "MacBook, Mac OSX Install Disc 2" Since the second disc is label "MacBook" is it possible they sent me the wrong set of discs?
Thanks

rk87,
Thanks for replying. I have a 500 gig hard drive which yields a 465gig usable capacity, so, at 30 Gigs available, I don't have 10% of the drive free. This may be an issue, but my more immediate problem is that I can't get the install disk to boot up at all.
I called apple support again see what I could find out about the install disks which wouldn't work. The support guy seemed like he had a lot of knowledge about the system and suggested trying the Tiger install disk (that came with the machine) to see if it would boot up, which it did. After that success, I tried the Leopard update disk in another iMac I have at home and it worked as it should. Since the disk worked fine on the other mac, the guy at tech support speculated that there is some sort of hardware issue causing the install shut down on the computer in question.
His speculation was about the memory installed in the machine which might be the issue. I had bought the computer from an Apple Authorized store here in town who upgraded the RAM to 4GIGs using third-party memory. Even though the memory seems to have functioned properly for the past year, apple support says that there could be some sort of incompatibility with the third party product causing the install disk not to work.
Apple support told me about running a memory diagnostic off of the Tiger install disk by rebooting with the disk in the computer and hold down the "D" key. After I got off the phone I ran the test which turned out to take an hour in its long version. The test indicated no problems, but apple had told me that it might not be totally conclusive. At this point, I'm taking the computer back to the store where I bought it and will let them figure it out.

Imac G4 wont boot past grey screen desperatly want to fix it!!!!

Hi there,
Please can someone help.....
I got a Imac G4 at the weekend for a bargin, but it wont boot up. When i turn it on it makes the noise and comes up with a grey screen with the apple logo and the loading circle. It doesnt go past this screen and after about 15 mins turns itself off.
Any ideas how i can get this running again (havent tried anything yet to be honest as im not sure what to do). I love these machines as i just think they are querky and would love to get it working again to use as my home pc (as even though its old it will still probably be quicker than my old microsoft laptop)
Thanks!

Did you try a PRAM reset?
http://support.apple.com/kb/ht1379
>I can't get the disk drive to open either
If the optical drive tray cannot be opened, what happens if you hold down the mouse button during startup?
As a brody indicated, a faulty hard drive cannot be ruled out. Instructions for removing this drive can be found in the ifixit.com guides as well.
If you can gain access to the optical drive, the best way forward would be to use an appropriate Mac OS X system CD in an attempt to start from that disc (holding down the C key).
If it is not possible to locate a correct system CD right now, another way could possibly be to try to boot from an Ubuntu CD for PowerPC instead (once again, holding down the C key) just to see whether the computer is capable of booting at all.

Satellite A105-S2001 wont boot after memory upgrade

I just tried to upgrade my memory from 512mb to 2 gb using 2 1gb memory chips from crucial. When i insert both memory chips at the same time my laptop wont boot, it'll attempt to but stop in the middle of the process and try again 5 or 6 times. Nothin shows up on the screen. The same thing happens when i put only one 1gb chip in. When i put my old 512mb chip in and one 1gb chip the computer boots but only recognizes 960mb or ram. i also updated my bios.
thanks

Sounds like incompatible memory. Fortunately, Crucial is very good about honoring their compatibility guarantee so you should be able to get them exchanged. You can get very strange results with incompatible chips due to the differences in timing specs. That would account for what you're seeing. I assume it works normally if you have just the original 512MB chip in place.

IMac G4 Wont Boot or Run Install DVD

As the title says really the iMac wont boot. You get the start up dong and the Apple logo appears but then it just sits there. It wont boot from the install DVD either. I have reset the NVRAM and PRAM and that doesnt help.
Any ideas?

Have you tried safe mode yet?
http://docs.info.apple.com/article.html?artnum=107393
If it does work, then read this article...

My 27inch imac (2010) wont boot ,

it gets to the apple logo and then to the next grey screen and stops there , but on one out of 100 boots it might boot as normal , its driving me crazy can anyone shed some light on this for me ....thanks
also if it does boot up as normal it might only go for a limited time and then freezes , i have done the hardware scan and it come up with no trouble found and also reset the pram about 100 times , tried to start in safe mode etc ..... done every combo of keys i can find referance to on the net and it still wont boot , exept randomly , also changed out the hard dive and the ram with known good units but nothing....... please if anone can help me before i go crazy that would be so cool.......... i also rang a local mac shop and the said that the logic board is stuffed and they will replace it for around $1000 ........ that is not an option.... and then the dude also said he will buy it from me for $300......... *** ...... maby he knows its an easy fix and is trying to screw me over....... anyone please help

You could have a failing hard drive. If you can, you need to backup all of your data.
Try and run Disc Utiity from your original discs or from your OS X 10.6 Snow Leopard install disc.
Try doing both permissions repair and hard drive repair.
If the drive reports any errors, then there is serious problem with the internal hard drive.
You could take a chance that it is not a logic board failing and purchase an external FireWire 800 hard drive and install a new version of OS X 10.6 Snow Leopard on the new drive, boot OS X from the new ext. drive and try to transfer/clone all of your data from your internal hard drive.
Find another Apple Store or another authorized Apple service center to bring your iMac.
When they do the diagnostics, If they find it's the Logic board, then you're out of luck!
You'll need to look for another computer.
If they find it's a failing internal hard drive, then you can have this drive replaced. The costs to replace the internal hard drive should not be too bad.

IMac won't boot after ram upgrade

For some reason, my iMac late 2013 3.4Ghz quad core i5 won't boot with new ram modules added. New ram is exact same specs as original that came with the iMac. I've tested the new ones on their own in the iMac, and the system boots up fine. Same goes with just using the original ram. But when I put all 4 together, the iMac doesn't boot up. Not even the chime.
Combinations I've tried are:
1-Old
2-New
3-Old
4-New
No boot

The only combinations that work are:

Boot good
1-Old

I just got off the phone with Apple, and they are saying all modules have to be the same size. ie. all 4GB or all 8GB. Can't mix and match sizes. Which is strange, because I've never heard of this. My Mac Pro has different speed ram modules, with different sizes in it. As long as I install ram in pairs, it runs like a charm. I've even heard the new iMacs don't have to have ram installed in pairs.
I'm wondering if slot 2 and 4 are maybe damaged? I haven't tried using just slot 2 and 4. To my understanding, you have to use 1 and 3 first. Can anyone confirm this?
Also, I've read a couple of people had to wait 30 seconds for the chime when they installed new ram in their iMacs. I didn't wait 30 sec to see if it would boot. Never heard of any Mac taking 30 sec to just chime in. lol Has anyone else experienced this? Is there a fix? Tx.

Unluckily, I need the SCA6000, and I don't have any other server in which to mount it, so I tried to downgrade the firmware to the release I had before the upgrade:
firmware version: 6.6.7
patchid: 136928-05
but the system does not boot anymore with the SCA6000 connected. I even tried an older fw release just to be sure (fw 6.6.1, patch 136928-01), with the same result.
I did not find mention of any incompatibility in T1000 or SCA6000 documentation.
Any help would be REALLY appreciated
Many thanks in advance.

Hi,
This looks similar to the bug 6630313 :: http://sunsolve.sun.com/search/document.do?assetkey=1-1-6630313-1
As described in the bug document, it is due to lower f/w rev. on the SCA6000 and solution is to upgrade the crypto card f/w to 1.1.0 /1.1.0 (bootstrap/operational )or later.
Another workaround would be to install system f/w 6.2.4 or 6.2.8 which works well with crypto card f/w 1.0.4/1.0.7.
Copying relevant part of the document for ref.
=======================
Work Around: The card is recognized by obp and prtdiag with firmware 6.2.4, so at this point customer is using firmware 6.2.4 as workaround.
Customer's crypto card is currently running 1.0.4/1.0.7 bootstrap/operational firmware. Customer can upgrade the card to newer firmware such as 1.1.0/1.1.0 by moving card to a system that boots successfully such as Ontario T2000. After such upgrade, install the card back into T1000 which should boot successfully with sysfw 6.4.0, 6.5.5 or 6.5.11 posted on Sunsolve.
Another workaround is customer can downgrade the T1000 sysfw to 6.2.8 so they can boot with the crypto card. After the T1000 is up and running with sysfw 6.2.8, customer can upgrade the crypto card fw to the latest 1.0 patch on the T1000 itself, then upgrade the T1000 sysfw to the latest
version posted on Sunsolve. This workaround does require customer to have access to an Ontario T2000 system.
Another workaround is customer can downgrade the T1000 sysfw to 6.2.8 so they can boot with the crypto card. After the T1000 is up and running with sysfw 6.2.8, customer can upgrade the crypto card fw to the latest 1.0 patch on the T1000 itself, then upgrade the T1000 sysfw to the latest
version posted on Sunsolve. This workaround does not require customer to have access to an Ontario T2000 system.

Imac g5 wont boot up . help pliz

Hey guys, need help with my mac g5, it wont boot up. The side light comes on but it wont up. thx in advance

Will it boot from the OSX DVD?

IMac G5 wont boot.

Hi guys, in my school there is a classroom with iMacs G5 and my job is to take care of it. So I decide to set firmware passwords on all iMacs. When I set firmware password on first iMac and I reboot it, that iMac cant boot to os x and single user even it cant boot mac os x installation disc. I reset pram and take off ram and nothing happens. What I can do? Version of os x is 10.4 Guys help me.

There are Support articles online at Apple's site which can help resolve the issue of a lost Firmware password; and how to set them correctly, depending on the hardware or machine series, or OS version.
Could be you did not do the process completely or in the correct manner of detail for it to work on that iMac G5. And depending on the OS X version, the means to do so can vary. An example of enacting Firmware protection is in the following page link:
•Setting up firmware password protection in the Mac OS X:
http://support.apple.com/kb/ht1352
•Enable password protection on your Mac:
http://www.macinstruct.com/node/507
http://www.thexlab.com/faqs/faqs.html
Since the powerPC G5 would be unable to run a system newer than Leopard 10.5(.8) the question of further upgrade is not entered into here; but for certain systems, oversight via Server software is almost always better when you have it. However old Tiger 10.4.x may be, that was a good system, and harder now to maintain since it is old, without updates, and relies on whatever third-party browsers, etc (tenfourfox) for any online access. The old server software would be hard to find, unless original DVDs were donated to the school.
There are other ways to secure computers, since anyone with physical access and time can remove an Admin password or an O.F. password. Articles for these older systems were on Apple Support site on how to secure Panther, Tiger, and Leopard, these were .pdf documents for download; maybe gone now.
I see how the need to protect the computers from such access before someone else, perhaps a student posing as a trusted administrator, for example. And I also see how anyone can ask questions and get answers to do this, before an authentic administrator could get around to doing so. That's why it is important to do the steps correctly; or avoid Open Firmware passwords if you can. Yet it is too easy with physical access to the computers, with a boot disc, etc to remove an Admin password. And a little harder for someone with a little skill, to remove the OF passwords set by an official who has authorization to control the Macs.
For greater protection, use physical controls in conjunction
with firmware password protection and encryption...
How to Password Protect Your Mac
How to Disable Automatic Login
How to Create User Accounts in Mac OS X
You may have to become an expert in troubleshooting hardware issues in those iMac G5s since that layer of difficulty is made worse by attempting the Open Firmware password in addition to having older machines, etc; and no server software to manage them in a group.
Hopefully you can work around issues as you find them...
Good luck & happy computing!

IMac G5 Wont Boot Up

I have an iMac G5 1.9GHz (iSight) which will not boot.
Dont know the prior history as was only given to me a couple of days ago.
It has managed to 'boot' twice.. once getting a kernel panic & once getting to the grey apple screen, but thats it.
I have just purchased a new (& correct spec) RAM chip for it but still nothing. This is also the model with 512mb RAM built in to motherboard (only has one onboard RAM slot at the base of the unit for upgrading/additional RAM)
It does not let me boot from the original CD as it doesnt get that far into the boot/startup cycle, likewise I cannot reset PRAM from the keyboard during this phase as well.
I believe that this model does not have a PMU reset button on the motherboard, but instead uses the power button.
Anyone offer any pointers as to how to kick start this iMac to life would be much appreciated.

You can try resetting the SMU by removing all peripherals, shut down, remove the power cord, wait 10 seconds, reinsert the power cord while holding down the power button, release the power button and push it again to reboot.
If you continue to have problems, there may be a problem with the motherboard, and you should probably take it in and have it looked at.
Let us know how you make out,

Imac A1200 wont boot

I have been given an Imac A1200 to have a look at for a friend. When I switch the power on I get the apple logo for a minute or so and the circle then the screen just goes to a series of horizontal lines and then nothing. I am a complete novice when it comes to macs so please be gentle with your answers lol. I don't know what OS it is running as I can't get anything up on the screen it won't even boot into safe mode

last night I tried a system restore pressing the windows key-alt-p-r key combination and I now get a white screen but nothing else.
Those keys combination, only clear the PRAM. I'm assuming you are using a PC keyboard and not a Mac keyboard.
OK. Let's start discovering which OS version is installed.
Turn on the iMac and press the Windows key (cmd key on Mac keyboard) and S. Hold them until you see the Apple logo.
This starts up the Mac in single user mode. Watch out, in single user mode the keyboard layout is US English.
At the prompt, type exactly this command (case-sensitive)
system_profiler SPSoftwareDataType
and hit return. You'll get an output similar to this
Software:
    System Software Overview:
      System Version: OS X 10.8.5 (12F45)

K7n2-L wont boot after bios upgrade

I have been very happy with the motherboard since i bought it in april 2003, been very stable and only had minor usb problems. And i finally decided to upgrade the bios from v. 3.7 to v. 4.1.
After the upgrade the machine boots up to the first windows that shows me the memory and the hard disk i have installed. I can also go into BIOS.
But the PC stops when its about to start booting up the HD or CDrom. According to the lights on the D-Bracket its trying to initializing the floppy controller.
There has never been a floppy drive in this PC before(i booted the PC on CDROM when i upgraded the BIOS).
I have tried the following things without success;
installed a floppy drive.
Cleared the CMOS(with the jumper)
Unplugged the cdrom and the hard disk.
Tried every memory configuration.
jumped the safe mode jumper.
It seems to me that i can only fix this by changing the BIOS chip....or the mainboard.
Anyone had this problem?

Azraeliz,
Sounds to me like perhaps you've overlooked a setting in the BIOS
Did you take note of the BIOS settings prior to flashing so you could put the settings back the way they were?
nuckelavee,
I suggest you start your own thread. I have a hard time believing there is no CMOS jumper.
Tried this? ***Starting your K7N2 Delta2 at default settings***

New Mac Mini wont boot after OS upgrade

First decided to upgrade OS to latest version
Its been 24 hours and I have not gotten past the grey screen with these 2 spinnung wheels
Dave

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, 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
b. 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
c. 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.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.
