Mac OS 10.4 Startup problems.

Hey guys,
Just recently reinstalled Mac OS 10.4 Tiger on my PowerMac G3 and now when i go to start the machine up where the Apple logo should be in the middle of the screen during boot has turned into a circle with a bar going through it. can anyone help me please.
P.S. It is on a completely legal Power Macintosh G3 450 mHz 256MB of RAM

See the following for help: Mac OS X- "Broken folder" icon, prohibitory sign, or kernel panic when computer starts.
You may need to reinstall OS X if you are not able to fix the problem. You should install more RAM as you have the barest minimum for running Tiger. Consider maxing out at 1 GB.
If reinstalling is the only viable option, then you may be able to do the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Power Mac G4 MDD strange startup problem

Hello ,
I have an old G4 MDD dual 1Ghz which is been used by my 6 years old son for gaming and watching movies.
I had Tiger 10.4.11 on a IBM deskstar HDD and Leo 10.5.8 on a seagate HD.
Everything was fine until some days ago, when my mac didn't boot from the first try…..black screen.
After a second attempt , booting was just fine.
I have now two system disks (IBM deskstar HDD) with 10.5.8 installed.
Mac is not booting always from first attempt….it takes two more with or without the option key pressed to choose a startup disk.
I have done all the usual…….reset PMU-PRAM…replacing battery,replacing cables,cable select the drives and now forced one to master and second to slave.
I have run Service Diagnostics 2.1.5………..ALL TESTS PASSED.
Still not booting normally….
Any suggestions please??
Thank you all!
PS:It is also loosing very often internet connection via ethernet……..I think it's not a router problem as all my other macs are working normally.

So, as I understand this only happens on the one drive - the main drive. Are you sure, given what you've described, that the "main drive" is connected to the correct cable connector? Usually, the drive ID is determined by its position on the drive cable. If I remember correctly the main drive is connected to the ribbon cable at the end of the cable while the second drive is connected to the middle connector (for a two drive cable.) Just a thought as it's been a while since I've used non-Intel machines. If this is the case then your slave drive may actually be the main drive and vice-versa.
The other alternative if this always happens on this one drive that the drive itself is failing. Is it possible to replace it as a check?

Mac Pro 3.1 startup problem

Hi all,
i have a 2008 3.1 8 core mac pro with 16gigs of ram.
I recently upgraded to Mavericks and since then sometimes it doest make it to the os desktop and hangs at the grey screen with the apple logo and some writing code appears from which i dont understand a thing...
Ill attach a photo to explain better. i guess you will not be able to descern the writing but so you can see the screen...
When it does boot up without this problem all is working perfect and not with a single problem.
The rate at which this is happening i would say is 3 or 4 crashes out of 10 start-ups...
What could be the problem ?
Thanks a lot guys !

I just managed to look at the blowup of the error message. Seems like something happens when one of the CPU is accessed. Some addressing problem.
To rule out bad hardware can you try starting up using an external hard drive (connect external drive with a working OS on it, then power up while holding the option key. Then choose the external drive to boot). Or the OS installer DVD (insert DVD then power on while holding "c" key). I guess you could also try to boot from the recovery partition (hold down option key when booting and select "recovery" hard drive icon)
If the machine boots reliably using any of the external HDD/DVD sources, then you need to reinstall the OS on your startup drive. Run disk repair just in case your HDD is having sector problems.
If booting from sources other than your startup drive doesn't fix the issue, then it's most likely a hardware problem. Either RAM went bad, or something worse. Dunno.

Startup problems w/ Power Mac G4 (QuickSilver 2002) M8667LL (dual 1 GHz)?

Startup problems w/ Power Mac G4 (QuickSilver 2002) M8667LL (dual 1 GHz)
Starts up with bong and then a long wait then screen comes on with old time smiley Mac and spinning beach ball then another long wait and then OS X loading bar and then a panic screen. Subsequent start, bong, and then hard drive spins for 6 or 7 minutes, then hard drive stops and then nothing. Could this be symptomatic of a hard drive failure?
Thanks very much.

I am pleased to report that I think the problem has been solved. Apparently the strange behavior can be attributed to overheating. After some on line research and the help of people on this list I opened the case and found that the logic board fan was clogged full of lint and dust. After cleaning it I discovered that the fan is inoperable. The computer is now operating with the case open and a small electric fan directed at the logic board heat sink. The computer has been operating flawlessly now for several hours. Will have to replace the bad cooling fan and clean the computer regularly. Thanks so much to all of the people who have responded to my request for help. Would like to mention that a firm with a canine connection charged me over a hundred dollars to report that their diagnosis is a faulty logic board.
Thank you.

MacBook pro when windows 7 has startup problem and Mac os doesn't work

I installed windows 7 on my MacBook pro and it did work well. But now windows has a startup problem and "startup repair" couldn't solve it, so I can't use both Mac os and windows and my laptop has become completely useless. Any suggestion?

Reboot and hold down command-R at the sound of the chime, that should take you to the Lion recovery partition, if it does go to disk utility and see if you have an OSX partition at all.

After a startup problem with my macbook pro i put it as slave and formatted the internal Hard drive. Now i want to install OS X Mavericks from USB

After a startup problem with my macbook pro i put it as slave and formatted the internal Hard drive. Now i want to install OS X Mavericks from USB
How can i do that?

What did you "put as slave?" What Mac model do you have, exactly?

Can anyone diagnose my startup problem from this screen pattern?

After failing to startup my Mac on about 8 consecutive attempts today, I finally got it to boot up, and now I'm afraid to turn it off for fear that I won't be able to re-boot.
Here's a photo of what kept happening:
http://www.doctorkeys.com/startup-problem-screen.html
This screen came up immediately, along with the spinning cog and the apple logo, both rather faint. But then those two disappeared, and all that was left was the gray screen with the pattern as shown in the photo. And that's as far as I got each time.
The display itself seems to be fine, because even when I couldn't use it with the Mac Pro, I was able to hook it up to my MacBook Pro and it worked fine.
Can anybody tell me what's happening?
Thanks,
Bruce Siegel

Hi-
To be honest, though, I was hoping that the pattern in the photo was so specific and common that someone would look at it and say, "Oh, of course! I've seen THAT one before. Do this and your problem is solved."
I have seen graphics cards produce that type of screen as a result of a few of situations.
One, if the card is miss seated.
One other is if a capacitor on the card has failed, while VRAM failure is another cause.
The first case is easy to fix; remove and reseat.
The second and third require replacement of the failed graphics card.
Cleaning the gold contacts with 99% isopropyl alcohol and thoroughly dusting the card while it is out is a good idea.
I have been able to replace a bad capacitor to restore a card, but luck was a big part of determining which one it was....

Startup problem with Lion OS 10.7.3

Just recently, I've been experiencing a startup problem with Lion. I don't usually have any issues running my Mac, so I'm at a loss why this is happening now.
I have an Intel Mac Pro running 10.7.3. I usually leaving my Mac running all the time and only restart when the need arises. In addition to being my main computer, this mac alsocontrols a MacMini that serves as a music server thru screen sharing.
This past weekend, I restarted my Mac and could not get past the grey screen. The mac chimes, the apple logo appears with the spinning gear, the blue screen briefly appears, but instead of progressing to the desktop it reverts to the grey screen with a repeating cycle of the spinning gear appearing (spins for a while, stops, disappears, reppears spinning, stops, disappears, over and over) - never progressing beyond that stage.
I decided to reinstall the system and things have been fine for the past few days. Today, restarting again resulting in the same problem.
I've tried several things without success. I disconnected all peripherals, reset the PRAM/SMC, ran Disk Utility from a install volume and ran repair and permissions (no problems reported). Tried safe mode startup - a progress bar appeared but never fully progressed and could not get to the desktop.
Recent changes included updating the OS to 10.7.3 and Adobe Photoshop CS5.5 - no recent hardware changes. No bluetooth devices connected.
Any thoughts? Thanks -

Thanks -
I've reinstalled the OS today and am back up and running.
But, since this is twice this has happened within the past week, I'm worried about might be causing this issue - besides bad luck. My Mac is usually rock solid - can't remember the last time I've had to reinstall the OS in the past few generations of OS X.

Startup problems--time for a new machine?

I have an imac G5 that I bought last February. In the last few weeks I've been experiencing serious startup problems. When turned on, the screen goes gray and the lines and pixels fragment and shimmer. It takes a long time to go to the main screen and often the screen isn't stable and freezes. It takes me eight to ten startups to get the system stable.
I've repaired disk permissions, repaired h-drive, reset Pram. Still a mess. My husband wants me to just get a new one and get something that is not an Apple this time. I'm resisting that.
I don't want to lose all my data and I've backed up what I can but I'm worried the data is corrupted and if I load it on to a new machine, I will experience the same problems.
Any advice? I'm not even sure if this is a hardware or software problem. I'm out of warranty so I am on my own, but I'm frustrated to be having these problems with such a new machine.
Thanks for any advice,

Startup Problem & "Zapping the Pram"

Okay, I'm having startup problems, and I did the Command/Option/P/R startup.
Next, I know that Command S, or Option S, something like that should take me to a startup equivilant of Disk Utility. It's been so long, I forgot what to do. I searched but cannot find the answer.
Hopefully someone here can help.
Thanks.

Why does my OS X 10.6.8 have various applications hang for several minutes, then resume. This is not a startup problem.

I upgraded to Mac OS X 10.6.8 a few weeks ago. It seemed to be running OK, so we upgraded another system also. Now both machine are, from time to time, stalling whatever application is running. Everything stops or runs veeeeeeerrrrrry slowly for several minutes even including bringing other windows to the front. The disk runs almost like it is swapping a lot. Then the system frees up and runs normally for a while. This is not a startup problem. I occurrs on systems that have been running for a day or two or more. It happens on an iMac and on a MacBookPro. Neither of them had this behavior before the 10.6.8 upgrade.

What do you mean with corrupt?
Why did you suggest that I created a new profile?
There are cache files and other system files that are created every time a user account is created. Sometimes these are corrupted in the OS and it really has no bearing on the specific application but it can lead to erratic behavior. Creating a new user recreates all these system files and thus it's almost like starting fresh. It's one step shy of re-installation of an OS. So because changing the user fixed the issue, then we have eliminated the fact that the application is causing the error and we know the OS is causing the error.
I can't just go in to that profile when I want to use?
I wouldn't recommend it. This can lead to more problems with the OS down the road with other applications and depending on where the corruption lies it can lead to issues with OS upgrades or even installing new software. The files that are typically most critical to users are stored in the Applications folder or the Documents/Sites/Pictures folders. You can easily drag them over to a new user account. If you have email being backed up for a product like Thunderbird you can also bring over many of the Library items as well.

I have asked the hosts to relocate your post to the Mavericks community where you may have more luck.

G5 Dual 2.3 PPC Startup problems

Hi
About every other time I start up the computer, nothing comes on the display, and within 1-2 minutes the fans start to accelerate out of control. I then push and hold the start button to abort the startup.
After 10 seconds I startup again, and then it starts up right.
What could be the problem? I am afraid that someday it won't start up at all, which is a big problem since I am running a recording studio, and need to have stable gear.
Thanks

Startup problem on my G4

hi to all!
Something that happened a couple of times (so far) with my Gigabit Ethernet: I switch the Power Mac on, then when I come back a few minutes later the monitor is on (well, it’s always on...), but the led is on orange, as when the Mac is off, and the Pro Mouse (attached to the keyboard) seems dead, as there’s no red light coming from it... however the Mac is indeed on, same noise (fan) as usual, and if I open the case everything seems ok and the internal red led is on. Then, both times, by pushing the restart button the G4 quickly loaded Tiger. First time everything seemed all right, but today the monitor changed its brightness all by itself a few times... and I’ve realized I had this sort of problem in the previous days too, but much less often and I hadn’t paid much attention to it.
I’ve guessed all these could have been caused by faulty Ram modules, something I already experienced last September, and solved thanks to this forum (even if last time the problems were of a different kind), or there are other possible causes?!?
Anyway, then I’ve run Rember, and the first time it was soon stuck while running Linear PRN, then I run it another time and... Rember went through all tests with no errors! Then one more test and again there was an error at the Linear PRN stage.
When I got the error free test I had told Rember to close also the Finder, while during the other 2 tests the Finder was on... and I wonder if this matter or not.
I guess all this confirm it’s a Ram problem, and tomorrow I’ll start checking what happens removing (or leaving) one module at a time... but I’m perplexed by the mixed results Rember gave me today: should I check every combination I’ll try more than once to be sure Rember results are ok or not?
Thanks
Stefano

ok, last Saturday I first run a few more times Rember, and got mixed results, but at least on half there was an error at the Linear PRN stage (and contrary to the first 3 tests, there was no patter in running the test with or without the Finder on), then I uninstalled one of my two 512 MB modules, the one I got new and installed last year btw, and after this on Sunday and today I've run Rember several times with always error free tests... I guess I've already found the faulty module, and the startup problem should be solved (as it occured only twice before, and a couple of weeks apart, I can't be 100% sure)... the drawback is that I'm back to 896 MB Ram, but I should get a new (and hopefully working) 512 MB module in a few days.
However, yesterday morning, soon after the startup of the Power Mac I noticed a few changes of brigthness of the screen... but I guess it should be a problem of the monitor, as in the last couple of days I also run several times CPUTest and always without any error in the tests

Imac G5 having Startup Problems

First of all I like to say I've heard many wonderful things about the imac, but this has not been my experience so far after just purchasing an imac this weekend.
This particular imac has a problem with startup. On the second day of experiencing this mac it would not startup and would freeze at the grey screen with the apple logo and spinning wheel. I also heard intermittent crackling noise coming from the lower left side, by the apple logo. After waiting for about 10 minutes with nothing happening, I turned it off by holding the power button. I proceeded to turn it back on and it booted up fine the second time. Chatted w/apple support and they told me to remove some startup files and empty my cache in the finder library.
The third day(today) my mac booted up fine, but when I went to open up the system preferences I got the color wheel that kept spinning, and the crackling noise again. Had to hold down power button again to shut down. After turning on a second time it seemed to work just fine.
Now I had to return the first Imac I purchased a week earlier because it kept freezing on me since the day I got it (note I did have the wireless keyboard and mouse). Needless to say the mac I have now has wires. I called the store from where I purchased it from and the person on the phone told me it was most likely that my ram was not seated properly when they installed it. Don't they do checks on this before they hand it over to you? Somebody please tell me that macs are better than this, of course I don't know if I'll believe you at this point.
So does anybody have any idea what is going on with my mac.

Sorry, I don't have a solution, but came here with a similar problem - two days ago I took my brand new G5 out of the box and it crashed immediately after the Setup Assistant told me I could "GO" - I got a Restart message, and it's been randomly crashing ever since. The diagnostics show no problems with the hard drive or RAM, or display, or anything! No apparent reason. Now I'm forced to go to Apple Care voice jail...good thing I kept my trusty G3 running, I have separation anxiety, it has been SO GREAT, but running OS8.6, can't go on forever.
