Slow boot, 3 min. of blue screen

Sirs
I have read many slow boot, and blue screen issues here. I have re-installed SL.
I have removed the LaunchDaemons, ran /sbin/fsck -fy (no repair needed).
I did repair permissions and received this message:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
I'm running OS X 10.6.3 on a MacBookPro 3,1 2.2 GHz Intel Core 2 Duo 160Gb drive with 69Gb avail.
It takes 3.5 minutes to boot with 3 of them stuck on the blue screen after the apple is gone.
any help would be much appreciated.
thank you
dan

mmmhhh i was also looking for suspicious trash in preferences. how did u manage to think it was that corrupt file?
Hi c,
The safest way to test for things like this is to create a backup clone (CarbonCopyCloner or SuperDuper! or Time Machine), make sure it's totally current, and then you can go in and do things that you wouldn't normally do; if you create more problems, then you can just clone the pre-problems backup back to your internal HD and you're back to where you started. I learn a lot this way (not all of it good! ). I have multiple backups, and I'm still freaked out when I move/trash/change something and my Mac won't boot. Then it's just a matter of cloning back or restoring things from TM.

HELP... after 10.4.11 update I can't boot past the blue screen

HELP... after 10.4.11 update I can't boot past the blue screen, and it is pretty frustrating, to say the least. Here's what happened last night:
I installed elgato's eyetv 250, and at the end it asked to update the software. I did so, and when I tried to run it again it said I had to be running 10.4.11. I quickly went over and downloaded the 10.4.11 combo updater to my desktop and proceeded to repair permissions on my disk so I could run the updater.
I repaired permissions and started the updater. It got halfway through updating and said something like it could not finish and stopped. No reason why - it just stopped. I tried it again, and it did the same thing after going about 25 to 30 percent through the updating process. I thought that was very odd, so I checked, and I was running 10.4.9.
I thought I needed to get the 10.4.10 update, so I downloaded the combo updater several times. It would not run, giving me some error message that it would not even open, so I thought I needed to restart my computer to get it to run. I did so.
That's when my computer would not boot. It gets through the initial white screen with the logo in the middle and the revolving circle, and while it stays there for a long time the fans run increasingly faster. They tame down, and then the blue screen with "Mac OS" on it and the blue progress bar comes up. There is no blue progress bar, though... that's where it stops and will not go any further.
Can ANYBODY help me get this thing booted back up? It was so late last night that before I started I didn't back the Mac up, and of course I have a project on there that I need to finish Saturday afternoon for a company.
ANY HELP WILL BE SO GLADLY APPRECIATED. If you can give me step by step instructions on what to do, you will surely be blessed! Thanks for any help,

Hi mrstang, and a warm welcome to the forums!
It sounds like Disk Directory problems.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.
The combo update for PowerPC-based Macs...
http://www.apple.com/support/downloads/macosx10411comboupdateppc.html
The combo update for Intel-based Macs...
http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
Repair Permissions before & after re-install, then reboot again each time.
If all the above do not resolve the problem, then it's time for an Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space...

Reset PMU and Powerbook won't boot past the blue screen with "Mac OSX" box

Hi-
Problem: I tried to reset my PMU, and now when my computer restarts it won't go past the blue screen with the "Mac OSX" logo in the box (and progress bar, that never fills up). I then also tried to reset PRAM, but it still won't boot properly.
Backstory--
I've had my 12-inch Powerbook G4 for about 3.5 years already, so things are starting to get a bit out of whack. I replaced my battery about 3 months ago, which has been great, but recently my power-cord has been wonky (having to unplug it and replug it in to make sure it actually charges the computer, the light flickers on and off, etc). Today it actually started producing SPARKS at the place where the thin white wire meets the white plastic power brick, so I decided it was time to get a new one. Brought it home, plugged it in, and since it seemed like the battery indication icon on the menu bar was all out of sync with the powercord colored-light, I tried restarting it a few times, but still the same. Then, I decided to reset the PMU, which may have been a huge mistake. And now it won't boot past the blue screen... Any advice? I'm going to try restarting it in "safe" mode, but I'd be so grateful for any recommendations. Hope I haven't done something irreversibly stupid with the PMU reset.
Thanks,
Samantha

Hello all,
Thanks for all of your great suggestions and info-- here are a few responses.
1) The disk I just borrowed from my friend appears to be the full retail version-- it looks just like the links that Ali B sent, and is in a large box saying "Mac OSX Tiger, version 10.4"... will this be the proper disk to do an Erase and Install? The only other disks I have came with my Powerbook when it was originally purchased, when it came Panther (I think, 10.3?). Would I use both sets of these disks to do erase and install? Or only the Tiger OSX disks?
2) I get the sense that Disk Warrior or Tech Tool might be necessary, but does it make sense to TRY to do erase-install before buying them? Also, are there any downloadable (for pay) versions of this, or would I need to track down the actual physical disks in Hong Kong or wait for them to be shipped?
3) I haven't yet tried the S.M.A.R.T. test, should I do that first? What is the procedure? Are there any results or ways to know if the drive is too far gone (so that I might instead replace the internal hard-drive) instead of pay 100 USD first to do the disk repair?
4) Cornelius said: "An alternative would be to completely reformat and erase the entire HDD, then re-install and restore your data from backup. If your backup is in the form of a bootable clone of the entire HDD, you can just clone it back." I use Super-Duper to back-up and the most recent one copied the whole thing-- what would be the later procedure of "cloning it back"?
5) As I'm able to use my computer pretty normally right now, but does it still mean that it might crash/die at any moment? Is there any way to tell?
Thanks so much!

Macbook only boots to a blue screen!!

This problem started today. I used software update to install updates of quicktime and itunes. After the restart all im seeing now is a blue screen and the white box in the middle. The bar in the middle doesnt start to load and now im seeing the rainbow colored spinning circle. I've turned it off by pressing the power button and the same thing. Macbook actually started acting up ever since I used file sharing from my imac G5 to trasnfer appleworks to my laptop. Appleworks was working fine for a few days. Then about 2 days ago appleworks would not start, several applications froze, applications started running slower. I also had to type in my password twice to log on. The first time i type in my password the screen turns blue for an instant then goes back to the log in page, and i have to type in the password again. Now I can turn it on but its frozen

did you try starting like this:
Press Option-Command-P-R until you hear two beeps.
Did you try starting up from the MacOS DVD?
If that works fine, its a software problem on your machine.
Start up from the DVD (holding down the c key at start up)
Then, dont start the sftware install, but go to the tools menu and choose disk-utilities and try repairing permission and the do a disk repair start up disk, while your at it.
After that, can you then (re)start from your computer in safe mode. Press Shift during startup to start up in Safe Boot mode and temporarily disable login items.
If you succed, its there is some software conflict in your configuration.
de-install any third party software you dont REALLY need. Eg extra widgets, wifi-scanners etc, auto-updaters, gmail-notifiers, virus scanning, what ever.
Trash all non-needed preferences from the folder yourhome/library/preferences.
then make a normal restart.
I would also reinstall the latest apple OS updater 10.4.8, but the stand alone installer, called the combo:
http://www.apple.com/downloads/macosx/apple/macosx1048comboupdateppc.html
You had a G5 right? that is a powerpc non-intel..
Well if its not a software problem, apple care will take care of you...
..good luck...peter

Unmountable boot volume error blue screen

I have a toshibia laptop that has crashed, I am eventually getting the unmountable_boot_volume error blue screen, the recovery disks that i ordered will not work, just disk 1 loads windows file then goes to a black screen with the cursor pointer, computer repair does the same thing, os is windows 7 satellite c655d-s5120 64 bit the bios does show the hard drive name and the boot log is showing the last driver loaded is windows/system 32/drivers/atipcie.sys, can I order a recovery for the windows 7 or is there any other ideas to fix this?not sure why this is happening

If you've already ordered a set of recovery discs, you probably don't need to order another one. While it's possible that the discs are bad (and maybe you should call customer support just to see what they say), it's also possible that you have a hardware failure of some sort.

HP Mini 311 Blue Screen

I am on my second HP Mini 311 netbook running Windows 7 Home, with a Verizon internal wireless card.
Both machines have the exact same problem. Blue Screen.
I found the following on the Verizon blog.
The problem is identicle to mine. Help please!
"I have an HP Mini 311-1037 netbook running windows 7, with a Verizon internal wireless card (HP un2400). I'm having intermittent crashes (BSOD) which always happen immediately after I terminate a wireless connection and then shut down VZ access manager. Basically, when I exit the program, the program window goes away, I see a smaller dialog box showing that the wireless card is powering down, and then the dreaded blue screen pops up. The error message code is BUGCODE_USB_DRIVERS. That error message seems odd since the internal card is not a USB device. However, when it powers up, I see a driver loading that is called "Qualcomm HS_USB_QDLoad So far, I've had 8 of these crashes. The event log always shows the same error message as the cause of the unexpected shutdown: bugcheck 0x000000fe (0x00000008,0x00000004, 0x852f05d4, 0x00000000) After the crash screen, windows tries to restart and fails. It then offers me the option of running a startup repair. That always fails. So then I have to do a system restore (roll back to an earlier restore point). That works, but it totally hoses up my A/V software. It then takes about 20 minutes to get that fixed. On balance, a real horror show. After the last two crashes, I discovered that if I decline to run startup repair, and just keep trying to do a normal reboot, then after the second or third try, it will start up OK without doing any repair or system recovery. That is also hard to figure out. HP technical support hasn't been very helpful so for. The HP support forum shows messages from a couple other owners of the same model net book who are reporting the same problem, so there may be a generic problem here. I tried updating the wireless modem firmware, using the latest download from HP. I was OK for 4 days, and then had 2 more crashes." .

I have had the same issue since I purshased the netbook last March. I have called both Verizon and HP in regards to the issue. First Verizon has told me that it is a HP issue and then i get connected to HP. I am on the phone with them for 5 hours cuz they want be to do re-do my network and other stuff. After a couple of days samething. Call back and the samething. I have called 5 times already until I talked to someone two days ago in Verizon IT department. The rep told me not to use the VZ access program due to some issues they are having with Windows 7. I tried to use my netbook this morning and I got the blue screen again without using the VZ access program. So I dont know anymore. You really have to pull your teeth out to get the right help from both companies. I am gonna try and call again later today and see what happens. Why can't us the customers get the proper help and no wasting our time.

IMac G5 - boots up to blue screen - tried everything

I have an iMac G5 (no iSight) 2GHz. Came across following problem (running MacOs 10.4.11):
- Normal boot: Mac goes through normal start up, but never gets beyond the blue screen - i.e. just before log in.
- Safe boot: boots up OK & can log in.
Up to this point, has been working fine for however long I have had it (maybe 3 years, I think).
I have trawled through the various sites and tried everything, including:
- Resetting PRAM
- Resetting SMU
- Disk Utility - repair permissions (some problems, now fixed)
- Disk Utility - repair disk (no problems)
- Apple Hardware Test from install disk 1 (no problems)
- Re-formatting disk & re-installing Mac OS from install disks (MacOs 10.4)
None of the above has fixed the problem - in normal boot it stops at blue screen, and if safe boot it gets through OK & works fine.
Next stop is the local Mac repair shop. But before I head off there, I wondered if anyone here could suggest anything.
The following link has three docs - full system profile, console log for unsuccessful boot (i.e. to blue screen) and console log for successful boot (safe mode):

Thanks in advance

my powermac is doing the exact same thing, did you ever find out what the issue was?
Thanks,

I can not boot past the blue screen, but safe mode is fine...

I have no clue what I did...
Everything was working fine on my iMac (which is from like 2008). I did a file migration transfer from my Macbook pro to the iMac and everything seemed to be good. I could see everything, etc. I went to update the software on the iMac since the computer has not been used in a while. After everything updated and installed the computer restarted and has not been able to move past the blue screen when booting. I can start in safe mode just fine. I have done everything I can find on how to trouble shoot with no luck.
I have reinstalled the OS X
I have held down every combo of keys when restarting the computer
I have made sure the correct disk is highlighted for starting up
I have done everything I could find online...
I do not have the option to erase under the disk utility, or repair?
I am so lost and have no idea what to do. Did the migrate do this? I could use any help! Thank you.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Macbook Pro boots to a blue screen. Only boots in safe mode

Hi, I am a long time reader, first time poster.
OK so I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this?!? Help!

You should not be having kernel panics on a new Mac. Kernel panic causes is sometimes hardware related. Your computer is still under warranty since it's new. You can either call Apple tech support or try the suggestions mentioned in User Tips: Kernel Panics and this article - http://support.apple.com/kb/HT1392

Imac 8,1 does not boot stuck on blue screen

imac8,1 mid (2008) 20" stuck on blue screen after boot ,It starts in safemode, below is a list of thing i have check so far
1 Apple hardware test (says every thing is ok)

Yet when i boot i get stuck on a grey/blue screen . it starts in safe mode though, Is there some EFI , firmware restore file that i can install ???
What else can it try????

Please closely follow Apple's advice in Gray screen appears during startup. There are a number of steps to take, be methodical and follow the directions closely.

I am booting to a blue screen.

I have an intel iMac 27" and everytime I boot it goes to a blue screen and thats it. I have did a permissions repair, disk repair, and cleared the VRAM. Any help would be appreciated. Thanks.

This is an older service letter however it may be applicable to your machine.
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh2235.html
Also I'm assuming you are still on 10.6.8, is that correct?

Macbook Pro with 10.4.11 boots up to blue screen and little squares...what to do??, Macbook Pro with 10.4.11 boots up to blue screen and little squares...what to do??

My MBPro, OSX 10.4.11 boots up to frozen blue screen with little pixelated squares. Whats wrong?

Have a local Mac/PC specialist look at your machine (not Apple or a Apple reseller)
Your machine is rather dated and Apple doesn't support your operating system any longer, but the local independant repair guy might be able to recover your files, install a new hard drive and upgrade you to 10.6.8, which is still getting security updates, which you can continue to use the machine a bit longer perhaps.
Your machine is too old to run 10.7 or 10.8 coming out this summer, but that's what I would wait for if your interested in a new machine.
In the meanwhile don't do anything banking related until you get a 10.7 or 10.8 machine, Apple doesn't support older OS X verisons, basically punishing you for taking care of your machine and making it last and not upgrading the OS on their timetable.
Be prepared for major change in 10.7/10.8, it's a differnt and unsettling, a lot of people don't like it and a lot of younger types do like it.
Perhaps you'll be better served on a Windows 7 machine, it doesn't change the UI or break all your programs, but you get malware more often.
No platform is good anymore, both have a bad side to them. Least on Windows the operating system and everythign can be reinstalled again and updates applied to stop the malware, you can use it for 10 years at a time.
Good Luck

N100 3000; Does not boot up; Lenovo blue screen

I bought my N100 few years back (Running Vista home edition). Battery has been dead for a while. It has been working fine by directly using the power source.
Couple of weeks ago, it restarted itself. But, it never got beyond initial "Lenovo" blue screen. Hard Disk light comes on momentarily, then nothing.... I can not even go to "Lenovo care". Nothing happens when I press "Lenovo care" button. The only button it recognizes is on/off button.
The only think I did a few days before this issue was using compress option to gain some space on my hard disk. But, did not see any issues after compress was done.
At this point, I will be happy to be able to recover my files from my N100 (I did not foolishly backup my files).
Any help is greatly appreciated.

F1 key did not work. My laptop does not respond to anything at Lenovo screen (it has white back drop not blue as mentioned earlier).
However, when I removed Hard Drive, it proceeded beyond Lenovo screen and displayed a message that OS is not present (Which makes sense). Does anyone know how I can get a boot CD? This way, I may be able to attempt running recovery utility on my Hard Disk.
Thanks,

Won't boot, hangs on blue screen

i was doing a software update of a bunch of things and the system ended up hanging for a very long time so i did a hard restart. when i turned it back on it went on very slowly, and got hung up at a blue screen.
i did another hard restart and it came on (slowly) but when the desktop loaded it only loaded the dock, and kept having an error dialog box pop up that said that 'Spotlight' was not loading, i could try again, ignore, etc.
i am now running the disk utility from the start up disk to check the hard drive. its possible this is getting hung up as well.
originally i came to here to see if there was a way to reinstall spotlight from the install disk. but with the disk verify getting hung up i'm a little worried. any thoughts?

You interrupted an installation in progress. This is bad news. You should always give it all the time it needs. Unless you have a Time Machine backup or a clone on an external drive, you might have to reinstall from the DVD. (And if you don't have either, it's time to consider getting some kind of backup. I would never do a major update without knowing I can revert to the backup if necessary.) In !0.6 this should preserve your settings and apps. When you are finished, install the 10.6.4 Combo Update.
http://support.apple.com/kb/DL1048?viewlocale=en_US
But before you do that, you might see if you can get it to boot in Safe Mode by holding down the shift key at startup. This will take much longer than a usual booup; it's doing some checking and repairing, so give it time. If you are able to boot in Safe Mode, repair Permissions from Disk Utility in Applications > Utilities.
And it sounds like the system might have been choking on too many updates. I generally only use Software Update to see what's available. Then, if I want to do an update, I find the standalone at apple downloads and, if I'm doing several updates, I only install them one by one.

Unable to Boot - Stoping at Blue Screen

Help Please.
I am unable to boot. I get to the blue screen but will not go to login page.
I can boot in safe mode and from install disk.
I have run disk utility and repaired disk & permissions.
I have also reset PRAM. Also removed login items from my account.
I have even done a archive and restore.
The only thing i havent done is removed any third-party items out of the /Library/StartupItems as I am not sure what items to remove.
I am at a loss as what to do next and would really appreciate any help I can get. Thanks in advance.

Darren:
It seems like your OS is not quite right. If you decide to re-install, first be sure that you make a good backup of everything you cannot afford to lose, then do a complete reformat, zero or erase, re-install and restore from backup. Here are some step-by-step directions you might find helpful:
Formatting, Partitioning Zeroing a Hard Disk Drive
Warning! This procedure will destroy all data on your Hard Disk Drive. Be sure you have an up-to-date, tested backup of at least your Users folder and any third party applications you do not want to re-install before attempting this procedure.
Boot from the install CD holding down the "C" key.
Select language
Go to the Utilities menu (Tiger) Installer menu (Panther & earlier) and launch Disk Utility.
Select your HDD (manufacturer ID) in left side bar.
Select Partition tab in main panel. (You are about to create a single partition volume.)
Select number of partition in pull-down menu above Volume diagram.
(Note: 1 partition is normally better for an internal HDD. External HDDs usually have more than one. See Dr. Smoke’s FAQ Backup and Recovery for tips on partitioning external HDD.)
Type in name in Name field (usually Macintosh HD)
Select Volume Format as Mac OS Extended (Journaled)
Click Partition button at bottom of panel.
Select Erase tab
Select the sub-volume under Manufacturer ID (usually Macintosh HD).
Check to be sure your Volume Name and Volume Format are correct.
Optional:Select on Security Options button (Tiger) Options button (Panther & earlier).
Select Zero all data. (This step take several hours.)
Click OK.
Click Erase button
Quit Disk Utility.
Open installer and begin installation process.
Please post back with further questions or comments.
Good luck.
