G5 won't boot other than 'safe mode'

I've got a first gen. G5 DP1.8 I use exclusively at work. My system locked two days ago, so I forced quit and restarted.
After that the system attempts to boot, then aborts. Came in yesterday morning and it fired up, fine. Restarted just to check it out and that was the last time it has booted in anything other than safe mode. I've reset the PRAM, NVRAM, PMU/SMU, repaired permissions, cache, all the usual stuff. I've tried removing startup items, etc. Seems to be a startup issue as the unit will boot in 'safe'. Finally out of frustration, I upgraded the OS to 10.3.8 thinking that could repair whatever startup issues, but no. I CANNOT get the machine to boot. I get the chime, booting screen, mac icon, and spinning, then it shuts down.
Here's part of the system log if it helps (the first half is an attempted normal boot, the second half is safe mode):

Apparently this has something to do with temp? The
machine will cold boot first thing in the morning
with no problem, but once it's been on for a couple
of minutes it will not restart (except in safe
mode).
It sounds like you have some component changing value with heat. It's hard to tell if it would be on the logic board or in the power supply though without swapping them out. It's strange it starts in safe mode though. Did you try resetting your open firmware?
Open Firmware reset: Hold the CommandOption+OF keys during startup. At the '>' prompt type:

>set-defaults

Won't boot in windows safe mode

I have a satellite 205, 20 months old, that began intermittently going to blue screen, then the problem became permanent upon start-up, including a partial display of windows logon screen, then the blue screen wtih message, "attempt to reset display driver & recover from time out failed", with reference to driver igdkmd32.sys. I could boot in safe mode. Attempts to update the driver resulted in a successful boot once, but soon went back to blue screen and boot menu. I restored with CD to out-of-box condition, but no improvement; worse if anything. It continuously recycles after initial start-up window and won't even reboot in safe mode. It shows a couple of bands of screen when trying to start windows, including black dots and even strange sound like a plucked guitar string. I booted from CD several times, and ran memory checks and chkdsk, even reset the memory. No problems revealed.
I can't find anything else to try and would appreciate any suggestions.

Dual G5 won't boot unless in safe mode post iLife 09' installation.

Alright so a few hours ago I had installed iLife 09 and the computer refused to restart therefor I did a manual force shutdown (by holding the power button till it shut off).
When I booted the computer up it began to load at the "spinning grey screen" then shut off within a few seconds.
I booted it in safe mode to try to fix the problem by uninstalling iLife by removing the files from the applications folder and deleting the receipts. After rebooting I still had the same issue.
Then I booted up in safe mode once more to open up Disk Utilities to fix the permissions. Found a few things it changed then rebooted once more... No dice.
http://discussions.apple.com/thread.jspa?threadID=2022959&tstart=60 I took a look at that thread, booted up in single user mode ran the commands and still nothing.
Additional note that seems different than most posts i've read so far:
I cannot boot from another hard drive (internal, external or partition) unless I am in safe mode.

HI,
Can you boot from your install disk?
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window where you see Capacity and Available. *Make sure there is always 15% free disk space.* Not enough disk space can cause directory corruption.

OS Mavericks won't boot without using safe mode

My macbook pro won't boot up when its not in safe mode. It gets to the apple screen and then freezes but I can move the mouse around. Safari also won't open even when it is booted in safe mode.

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running a program at the suggestion of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only run the test in safe mode, proceed anyway.
If you have more than one user, and the one affected by the problem is not an administrator, then please run the script twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, just run the script as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the script will run anyway, but it will produce less information. In most cases, the difference is not important, so don't worry about it.
If you're not logged in as an administrator, you won't be prompted for your password. The script will still run. It just won't do anything that requires administrator rights.
The script may take up to a few minutes to run, depending on how many files you have and the speed of the computer. There is no indication of progress until it's done. Wait for the line "[Process completed]" to appear in the Terminal window.
You can then quit Terminal. The output of the script will have been copied to the Clipboard automatically. All you have to do is paste into a reply to this message by pressing command-V again. Please don't copy anything from the Terminal window.
If any personal information, such as your name or email address, appears in the output, anonymize it before posting. Usually that won't be necessary.
When you post the output, you might see the message, "You have included content in your post that is not permitted." That's because the forum software falsely identifies something in the post as a violation of the terms of use. If that happens, please post the output on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the output of the script. They speak only for themselves, and I don't necessarily agree with them.

MacPro 1,1 July 07 won't boot except in safe mode

Hi everyone hope one of you is a real man of genius. My mac pro started freezing then wouldn't restart, it would hang on the blue screen @ start up with just a cursor. I tried all remedies I know (flashing everything,resetting everything,hardware check,tech tools,disk warrior,ram and battery removal) and same problem. I then did a clean install of snow leopard and then it hung on the grey screen. After many clean installs got it to work in normal mode once but then froze a week later. I also did a clean install of leo and it hangs on the blue screen still. It will start in safe mode no problem. I installed a new hard drive and new install with same results. It is a hardware problem for sure after new hard drives and clean installs and its not the memory, I installed them one at a time and got same results.
I feel it has to be the nvidia 7300 but I have no artifacts or lines or distortion before it occurred.
Please Please help me ! Been on Macs for 10 years and never had a problem. I use my mac for work and am losing $ daily!!! I live in NYC and taking it to apple will be expensive and very painful.
I just want to be fairly sure if its the video before I spend $350 on the ATI 4870.
Thanks in advance and Happy New Year fellow Mac freaks!

RAM has to be installed in matched pairs, not one at a time, one set at a time?
Disconnected all the devices and cables? and just k/b and mouse left?
Pulled all the hard drives out except one?
Disk Warrior etc are current and on a reliable current "Apple-only" boot drive? and that drive system works 100%?
The 1,1 has an SMC button for reset - under drive bay #4 and just above PCI slot #4 at top, takes 5 seconds only to reset.
I had to throw out my Apple RAM (4 x 512) last year as it was beginning to fail. And replaced the 7300GT with 8800GT before they vanished.
OWC sells an ATI 3870 - but maybe those are gone now? and looked to be over priced (was $219 before).
The best way to format a drive is to install Windows and if you have WDC drives, use WD's latest diagnostic utility. It does work, and better than Mac OS utiliities.
Not sure what there is to flash, other than SMC reset and PRAM/NVRAM not much.
I'd install Tiger OEM that it came with if you can just to see how that behaves.

MacBook Pro won't boot regularly or safe mode, getting patches of black white and grey noise on screen

It was giving me video problems at first and now has pixelated black grey and white designs popping up when I turn it on. It loaded up in safe mode the other week but now it just stays at the gray apple and spinning icon.
I am posting this from an iPhone right now so I am not sure how to attach the picture I took. I will try to upload it after.

Apple store genius bar is the place to go for a definitive diagnosis. If it is the logic board, you may be in market for a replacement MBP. Unless you have some emotional attachment to that particular MBP, it may not be cost effective to repair it. (I note that yours is a pre-Unibody MBP)
If you are lucky and it is the display, you might be able to get a replacement from iFixit or Powerbook Medic for a reasonable price and do the swap yourself.
Good luck.
Ciao.

Problem with start up - won't boot. Tried safe mode, recovery mode etc.

Have also Tried Single user which just shows "error loading kernelcache" and before this reads "loading kernel cache file '\com.apple.recovery.boot\kernelcache'... And then read error ok? goes to grey screen with apple logo and no entry symbol? Any advice?
Tried all the online resources and have fond little help. Have not downloaded or Changed any settings...
Happy 2014!

iCloud does not back up a Mac. "MacKeeper" is a scam. Apparently you have no backups at all, which means that you're in immediate danger of losing your data, if it hasn't already happened.
If you want to preserve the data on the startup drive, and it's not already backed up, 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, you can skip this step.
There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

OS 10.2 Won't boot even in safe mode

I was having problems with the Finder on my work i-book so reinstalled the OS. The first disc was fine, though the second wouldn't be recognised. Since it said that this disc could be installed later, I quite the installation and rebooted.
I went to the log-in screen and discovered that my password would not be recognised.
So I used the install disc again to reset the passwords, though didn't actually do the installation again (and since it wouldn't let me shut down properly within the Installer I had to reset the computer by just holding down the power button).
Upon restarting the password now worked, though when I logged in I got taken into Darwin. Since I didn't really know what to do I restarted again by holding down the power button.
And now nothing happens. I get to the grey screen where the apple logo is visible and the little spinny icon goes round but nothing happens after that; I've tried with and without the install discs installed (holding down c obviously) and have also tried to do a safe boot following apple's instructions with no joy.
Anyone got any further suggestions?
Many thanks,
t

Sometimes when the 'C' key doesn't work, you can try the Startup Manager described below:

Hope this helps.

My firefox installation keeps crashing when I start it up in anything other than safe mode, how can I see the details of the crash report?

I've had Firefox installed on this computer for a couple of years, but only really started using this computer in the last 6 months. Originally Firefox 14, then Firefox 17.0.01, then finally 19.0
It crashed yesterday on starting, I uninstalled and reinstalled and same issue. I regressed back through version 17.0.0.1 and Firefox 14. I updated Shockwave, Flash, Java. I also uninstalled Divx, AC3 and Adobe Reader (recent installs/updates)
Updated MIcrosoft security essentials and ran a scan, no issues discovered. Updated and ran Superantispyware and found 1 Trojan which I removed.
Crash reporter comes up as soon as the firefox link is actioned. Can start firefox in Safemode.

please start firefox in safemode (by pressing the shift-key while it is launching) & go to ''firefox > options > advanced > general'' & disable hardware acceleration.
for some background on that issue you can also refer to [https://bugzilla.mozilla.org/show_bug.cgi?id=812683 bug #812683]

ALWAYS BOOTS UP IN SAFE MODE

MY MAC ALWAYS BOOTS UP IN SAFE MODE. I REPLACED THE KEYBOARD DUE TO A JAMMED SHIFT KEY WHICH WAS CAUSING IT TI DO THE SAME THING, BUT ITS DOIN IT AGAIN. CAN SOMEONE HELP PLEASE?

ACTUALLY IT BOOTS THE RIGHT WAY IF I LEAVE THE KEYBOARD OFF UNTIL THE SIGN IN SCREEN COMES UP. AND YES IT IS A WIRELESS. IF I TURN THE KEYBOARD ON BEFORE I TURN THE COMPUTER ON IT WILL BOOT IN SAFE MODE. IS THERE ANYTHING ELSE THAT I CAN TRY, OR SHOULD I JUST SAY FORGET IT, AND WAIT UNTIL THE SIGN IN SCREEN COMES UP BEFORE I CUT IT ON?

Will not boot up in safe mode

Here's another headache which is testing my temperament to the extreme.
My Mac crashed this morning and when I restarted I got the classic Spotlight in the corner icon. The usual procedure here is to restart in safe mode, empty the wastebasket and then restart as normal.
Unfortunately, my Mac simply refuses to boot up in safe mode! Instead it shuts down. Now this is nothing to do with me leaving on my finger on the button too long or not long enough, as I've done the safe mode restart countless times...the bugger just will not go into safe mode no matter what I try and do.
Any insights would be greatly appreciated before my full head of hair turns into a massive bald patch!!
PowerMac G5 Mac OS X (10.4.2)

I just had an issue like this. I was able to boot up with an external firewire drive, although it was a lot of trouble. I think doing an option boot finally worked; holding down the option key, I eventually got to see the firewire drive was bootable, and booted from it.
I put the thing in verbose boot mode (command - v , I think; but please look it up. I have no Mac books at work to check). In verbose mode, you could see that the hard drive could not mount; the OS tried to do fsck, but it failed around 2/3 of the way, and the CPU was halted.
I was occasionally able to boot normally, but never in safe or single user modes; these do a disk test first, which invariably failed.
I could see from the system and console logs when I managed to get the firewire boot going that there were repeated errors trying to access drive s03, the internal SATA drive. The logs on the SATA drive showed huges numbers of errors. At a wild guess, for some reason a lot of sectors went bad all at once. There had been a some erratic behavior before, but I'd put that down to the single processor G5 problems. (these were non video related, just freezes).
Applecare wanted me to carry the huge thing into the local Apple store, but I persuaded them to just send me a replacment hard drive, which they did. The new one works perfectly.

Boots only in Safe Mode - Macbook mid 2007

My Macbook mid 2007 with Snow Leopard will not boot correctly. The only successful means is Safe Mode (key S during boot).
All measures published in various postings have been conducted without any peripheral devices. These are:
verify harddisc
verify RAM
resetting PRAM and NVRAM
A detailled overview can be found under here.
The existing original RAM and harddisc were successfully tested using a second identical Macbook. A new installation of Snow Leopard on the harddisc using the second Macbook was successful and started in this second Macbook as expected. This harddisc was then inserted into my Macbook, but it would not boot. Hence it is safe to exclude problems with RAM and the harddisc.
Attempts to boot with the Snow Leopard DVD (either via C plus boot or Option during boot and select Install DVD) are not successful. Attempts to boot from an external drive are also not successful. The boot process (regular, DVD, external) progresses to different states including grey screen with Apple and frozen wheel. There is no consistency.
From the various postings I have found and studied along with my numerous tests, I have deduced the following possibilities:
There is a problem with the GPU.
There is a problem with the keyboard (maybe someone spilled something).
I have found numerous solutions for "boots only in Safe Mode". All include booting via Install DVD, but this does not work in my case.
I have exhausted all my possibilities. Hopefully someone can provide more insight.

What I am not able to test is booting with an external CD/DVD drive. However, there is no indication that the built-in drive is malfunctioning.
If you have a second MacBook (#2 working OK), you could use its CD/DVD drive loaded with the 10.6 DVD as the target disk to boot into, as the first Macbook (#1 the troubled one) reportedly cannot see a 10.6 DVD normally.
How to use and troubleshoot FireWire target disk mode
In your case this would be:
With the MacBook(1) on (Host), the MacBook(2) off (Target) connect the firewire cable.
Start the MacBook(2), hold T key to make it the boot drive. It will appear on the MacBook's(1) Desktop.
Insert the 10.6 Install DVD into the MacBook(2).
It too will appear on the MacBook's(1) Desktop.
From the MacBook(1), select Restart and hold down the Option key to select Start-up Manager.
From Start-up Manager, select the 10.6 Install DVD which will take you into the installation.
If this occurs, then you have booted into the install 10.6 DVD, From there you could try and install it, see what happens.
However, if it does not see the DVD disk, then this would indicate a defect in the logicboard (motherboard), though which component I would not guess.
If it does see the DVD, in Macbook (2) and can boot into it,… I'd be surprised!

Tecra 8100 only boot up in safe mode

I seem to have lost the display drivers to my Tecra 8100.
Since I attempted to use an extra screen which worked fine until I came to boot up the following day when it would only boot up in Safe Mode.
What have I done wrong and how can I rectify it?
Driver detective doesn't work, just comes up as having performed an illegal action.

Lars,
I'm afraid that it seems that Toshiba no longer provide the drivers for the Tecra 8100 as it's such an old computer, around 12 years old. I have been on the Toshiba website and tried again on the site you suggested but to no avail. Sorry about that but am still hunting.

G4 powermac will not boot up nomally unless i boot up in safe mode help ?

My G4 power mac will not boot up when switched on itakes several re boots and somtimes crashes.
Will boot up in safe mode. but this only allows me to use some of the application software i need and not all of them.
Can anyone help I thought it could be the hardisk but why would it boot up in safe mode?

Boot from the Tiger installation disc 1 (hold down 'C' on startup). Don't touch the installer, go to the menu bar and select Disk Utility (I think it's in the Tools menu on Tiger).
In DU, select your internal drive in the sidebar (the top item with the makers name and serial no.). Run Repair Disk.
If problems are reported, run it again until the green message says the disc seems to be OK.
Quit DU, quit the installer and restart.
If DU says there are problems it can't fix, you may need DiskWarrior.
Either way, let us know the results please.
(PS; this is the Intel iMac forum - PPC are next door!)

Hp g62 freezes and won't run except in safe mode

My hp g62 won't run except in safe mode and when I run normally it freezes. I been reading in the post of the same existing problems and tried the start up test and it failed the short Dsp. What should I do

Hi @Daver1976 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP G62 Notebook and Short DST failing. Here is a link to restore the BIOS.
You could try safe mode disk defragmenter it will scan your computer. Just click on start and type disk. Select C: and select defragmenter.
Please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices.
Here is a link to do a hardware test. It can let you know if something is failing and the code it gives you would be helpful.
Hope this helps you, please let me know if you receive any errors.
Thanks.
