Hangs on Blue Screen on Startup

Hi all.  I know there are similar posts to mine, but my questions can not be found so far in my searches.
I have a 2009-ish refurbished Apple Store MacBook Air with a SSD.
Today I restarted my computer, it seemed to be running a bit hot and slow.  After rebooting I could only get it to get to a blue screen and no desktop.  Computer boots normally with grey screen, apple logo and gear icon... following which I get a blue screen, sometimes with a gear other times with no gear or an alternating with/with out gear on blue screen.  Screen never goes to desktop screen but momentarily there appears to be a single pixel square (or possibly a 4 pixel square) of white near the upper left corner that appears momentarily over the blue, then gone.
After searching I have tried the following things...
Tried booting in safe mode (holding down shift) with same results.
Tried doing a PRAM reset with same results.
Tried booting in verbose mode with same results.
Tried booting in single user mode and did the following:
ran fsck -fy and disk verified with no errors, however it did indicate that something had updated.  rebooted with same results.
again ran fsck -fy multitple times with no errors, rebooted with same results.
ran mount -uw, disk reported it was HFS read only journaled... changed drive mount to -o for read write sucessfuly, then ran fsck again and rebooted with same results.
So according to fsck the drive is fine, but if I reboot and then try mount -uw again, it again shows as read only.  I am not sure if this is normal or indicates there is in fact a hard drive problem.  Or perhaps there is a bigger issue.
I do not have a usb CD Rom drive to attempt to boot from OSX Snow Leopard disk in order to test further, I am stuck at the moment.  I do have another laptop and a MacMini which I could potentially use to share a CD over WiFi, but I am unsure if I can boot from a shared CDROM via wifi and if so how to boot into that mode.
Does this sound like a drive issue or potentially something else like a virus or motherboard or graphics card failure?  Thanks in advance for your time and efforts to answer this question.

Update: Using Remote Install I was able to remotely boot my mac from another laptop's CDROM drive and run Disk Utility from the installer which again passed with out errors like the fsck command.  I also repaired disk permissions.  Upon reboot to the internal SSD, I am again getting the same blue screen.
So, since I can boot remotely and my disk seems to check out ok I am guessing now that there is something wrong with my OS, some kind of corruption has occurred, but that is just a guess.  It is possible I guess for there still to be an actual hard drive or hard ware failure of some kind.
Any help is still appreciated.

  • Macbook pro hangs on blue screen at startup

    I've been having intermittent problems with my Macbook Pro starting up, but this is the first time it's completely failed to start up: I get the startup sound, the grey screen with apple logo, and then it just hangs on a blue screen, with a grey startup dial, and nothing happens. It was working fine up until this evening; it's confusing to say this, but it seems to have moods where startup is an issue. But I have taken it in several times for this very problem: the first time, they replaced my hard drive, the second I was told to reinstall OS X, and then add software back one program at a time. All I had on this machine was Adobe Creative Suite 4, nothing which would cause any issues. I don't even have any fonts on this machine!
    Desperate to know what might be the problem; I've tried a few of the basic troubleshooting work arounds and none of them are working. Does anyone know what the issue could be?
    Help!

    If you get a external USB or Firewire drive, you can hold c and boot off the installer disk #1 that comes with your computer, the second screen in is a Utilities Menu and Disk Utility.
    Select the EXTERNAL DRIVE and Erase, format HFS+ Journaled GUID partition.
    When that's completed quit Disk Utility and your back in the OS X installer, install OS X on the EXTERNAL DRIVE.
    When that's complete quit and reboot hold down the OPTION KEY and select the External drive to boot from.
    Now GRAB THOSE FILES!!! 
    After that you can do what you want to the boot drive, if you can't fix it, you can always install OS X again (without formatting) and it should leave your programs and files alone. But if something goes wrong you have a copy on the external drive.
    You can choose to Disk Utility format and reinstall everything, OS X, programs and files as well.
    If for some reason you can't access your internal drive, either booted from the install disk in Disk Utility or via the external drive, it's possible your hard drive died.

  • OSX Server Hangs on Blue screen at startup

    We have an Xserve Running 10.5.8.  We have been having strange issues for some weeks with client's logging in and their desktops being missing.  Last Friday I noticed that the backup was not running correctly and I had a student who had lost her work mysteriously too.  I decided to restart the server to see what would happen.  On restart I cannot log in to the server either remotely or locally because after the white apple with spinner screen the machine goes to a blue screen with no login window.  Services are up and running, I can view and use Server Admin and Workgroup Manager, and I can ssh into the server.  I have trawled the internet in search of answers but all to no avail.  There are some errors in the log but I am not familiar enough with these things to know which are significant to this problem.  To further complicate matters the OSX server disk is nowhere to be found, hasn't been seen since well before I arrived on campus.  I have ordered Snow Leopard for this machine but would like to get to the bottom of the issues.
    I have booted into safe mode from ssh but this has made no change to the situation.  I am relatively new to comand line management of macs so please don't assume I know how to use it like an old pro.  I am learning rapidly.
    Thanks

  • Hanging on blue screen during boot (but Safe Mode OK)

    Strange stuff with my iMac G5 -- machine boots normally, gets through Apple icon and spinning spiral, then hangs on blue screen and stays there. Mouse cursor moves but that's it.
    Safe boot works normally, all safe-mode functions good. But need network, other services back.
    History: Spent most of past week downloading huge, multi-gig file. It eventually downloaded successfully, but during process my wife put computer to sleep a couple of nights without halting download.
    Didn't have adverse effect first time, but it froze Finder second and third times, necessitating reboots. Also killed wireless connections for all PCs in network those two times iMac needed reboot, had to reboot gateway as well.
    Morning after download finished (Friday), iMac failed to wake up from sleep, wouldn't boot normally, had to go into Safe mode.
    Additional RAM was recently installed, but has worked well. Safe mode shows full two gigs in use.
    Solutions I've tried, without success:
    -- Trashing network preferences in both user and system
    -- Re-installing Finder and NetworkInterface apps using Pacifist
    -- Removing recently installed extensions in System (extensions put back after that failed to resolve issue)
    -- Removing recently installed Startup items (again, put back after that failed to resolve issue)
    Clearly it's got something to do with the network interface, but I've tried everything I know how to do. Any ideas? I'm out of them.
    Thanks in advance.

    The Airport card is not removable in this model -- 2nd rev G5 iMac, with automatic light sensor.
    But -- I think I've found what's wrong. Unfortunately there's no easy fix ...
    It's most likely the bad-capacitor issue that plagued the 1st rev of G5 iMacs. (This particular machine was a refurb bought direct from Apple in the fall of 2005, so it's possible bad caps were put on during the refurbishing.)
    I first heard about the problem a couple of days ago but figured a hardware diagnostic test would catch it. More online research reveals that the hardware test doesn't.
    When I popped the case this morning to yank the new RAM, there were definitely a few capacitors that had domed tops. Nothing spilling out anywhere, which was what I was looking for, but I've since found out that even contained bulging is a sign of failure. The capacitors should be instead perfectly flat-topped.
    So ... I'm gonna call Apple tomorrow morning and see how much it would cost to replace the mobo. There have been reports in forums that Apple sometimes offers to do it for free, even in cases occurring within the few months.
    See this link for examples of Apple picking up the tab for complete mobo replacement: http://www.macosxhints.com/article.php?story=20090314071508354
    If that offer isn't made, I will look into having the capacitors replaced. This is at the edge of my own technical abilities so I will first ask my techie friends if they can do it for $100 or so, plus parts ... and if not I'm gonna try to do it myself.
    This guy shows you how and sells inexpensive parts to do it with: http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php
    There is also a guy out in Missouri who replaces bad capacitors on motherboards for a living: http://www.badcaps.net/ Looks as if he'll charge between $80-120 including shipping and parts. So I may go that route.
    In any case it turns out Apple did know about this issue back in 2005 and even instituted a program to fix iMacs that had problems stemming from it for free. (Dell Optiplex machines also had the same problem, which was traced back to a few Taiwanese manufacturers.)
    Unfortunately there was no recall (Apple would never have lived that down) nor was the issue highly publicized. You had to wait until your own machine acted up, and then the free-repair program expired at the end of 2008.
    I myself never knew about it until a few days ago, and I usually keep up on this stuff -- which is something I will make very clear when I'm on the phone with Apple tomorrow.

  • HELP! iMac G5 hangs at blue screen, but boots in Safe Mode

    Please can anyone guide me to recover my iMac G5 PowerMac 8,2 running OS X 10.4.11.
    Problem; Mac hangs on start-up at blue screen after grey Apple screen. Mouse pointer eventually appears but that is all.
    Actions taken so far without success:
    1.  Disconnected the printer and rebooted - no success.
    2. Booted in Safe Mode - first time the screen was completely scrambled but with safe mode log on screen showing through.  
    2.1 Rebooted in Safe Mode OK This has not occurred again and I have entered Safe Mode twice more without problems.  But worrying!
    2.2  In Safe Mode I ran disk Utility and verified and repaired Permissions, mostly old EpsonPrinter files.
    2.3  I also verified the Disk, which was reported OK.
    2.4  I was able to save critical documents to USB............  Phew!
    2.5  Reboot in Normal Mode - no success
    3. Reset PRAM
    3.1 Reboot in Normal Mode - no success
    4. Reboot in Safe mode - works fine.  NOTE: time and date appear to be correct and dont need resetting.
    4.1 Run Disk Utility again and Verify Permissions - OK.  Nothing needed fixing.
    4.2 Run Disk Verify - Passed OK
    4.3 Reboot in Normal Mode - no success.  Hangs at blue screen with mouse pointer visible and working.  Then pointer vanishes.
    I would be most grateful for your help in moving this forward

    Got to figure out which which of the things dropped when you boot in safe mode is causing the problem.

  • IMac G5 running OS 10.4.11. Started playing with a bluetooth speaker (may or may not be related). Now I cannot get past the blue screen on startup. I can get into safe mode. Tried install disc for disc utility and reloaded OS. Still get blue screen.

    I have an older iMac G5 running OS 10.4.11. The other day I started playing with a bluetooth speaker (may or may not be related). Now I cannot get past the blue screen on startup.
    I can get into safe mode. But no regular startup.
    I tried disabling bluetooth, thinking that might be related. It didn't help.
    I even tried using the install disc to run disc utility. That didn't work so I reloaded the OS.
    But I still get hung on the blue screen when trying a normal startup.
    All help would be appreciated.

    Try resetting the PMU/SMU and PRAM/NVRAM. You'd need to identify the mode of resetting depending on the model of your G5 iMac. The Apple support sites that would help you for this are –

    So for some reason or another, I've ended up with the "blue screen" at startup problem. when I start my macBook in Leopard, after the apple logo, I get stuck permanently at a blue screen. The first thing I did was to repair the disk but the disk utility told me my disk was fine. Then I tried to do a restore of Mac OS X but after about a minute I get a error message saying "Restore Failure could not restore- File Exists". I have no idea how or why this happened or what it means. I would like to try apple's solution to the problem but they are very vague. They say try an "Archive and Install installation of Leopard". I have no idea how to do that! They say it is covered on "page 7 of the Install & Setup Guide included on the Leopard DVD" but I can't seem to find this so-called "Install & Setup Guide" anywhere on either of the two DVDs. Can anyone tell me how to fix this?

    It's all in http://support.apple.com/kb/HT1545?viewlocale=en_US BTW, the setup guide's on the Leopard installation disk (retail version) and not on the disks that came with your machine.

  • Blue screen at startup---have tried EVERYTHING!!!  Any ideas???

    Hi there, I've got a really frustrating problem concering my husband's iBook G4. One day he got home from work, tried to start up, and got only a blue screen (no cursor.) (This is shortly after updating to 10.4.11, incidentally...coincidence?) We went to the forums, and tried numerous fixes, including:
    Booting from install and running disk repair (none needed)
    Booting in target disk mode with my mac and removing the login.plist file
    Removing all login items from both user accounts in target mode
    Attempting a boot (and eventual restore) from the external firewire backup, but it won't get past the blue screen here, either.
    It started up in safe mode a couple of times, and even restarted in normal mode once, but then in primary account froze back up after a few minutes. Then it wouldn't even start in safe mode.
    Then we did an Archive & Install from the original startup (Panther) but when it got to the login screen, it wouldn't accept either user password (even though the hint indicated we were using the right ones) and then froze. It now won't even boot from this disk, or start up in safe mode.
    Everything seems to be intact while perusing it in target disk mode; even ran a hardware test from the Apple Hardware Test disc and that all checked out (no idea if this would have made any difference, but I'm grasping at straws, here!)
    I know we did a couple more things suggested in the forums/support pages, but I can't remember what they are at this point...my brain is fried! (Also remember following Apple's instruction's for what to do when you get a blue screen at startup...tried this first thing to no avail.)
    Soooooo...any suggestions or ideas? We would greatly appreciate the help!
    Thanks so much!
    Jennifer

    Hi Jennifer,
    Ok, so...what's going on today is that Leopard will open to the login screen (sometimes I can log in but generally not), but then the cursor is frozen, as is the keyboard (can't type to login or use shortcuts) and even a usb mouse doesn't work. The only thing I can do is power down with the off button, and upon restarting, if I get past the login, get the message "Computer was restarted after Mac OSX quit unexpectedly" or something like that. (Just restarted from frozen login screen and got blue screen again.)
    Wondering if it's Leopard or my wonky install (we started up in target mode, with the install disc in the drive, and opened the installer on my mac, then chose the broken mac hd to install to. Seemed to work, but may this be related to the driver issue you mentioned?) We did it this way (after doing a zero-out erase) because it wouldn't even start up from the install disc itself.
    It sounds to me like this method of installing is okay. If you did not have the correct drivers, you could never get as far as you do in Leopard. I am wondering why you install with the disk in your Mac and not in the iBook.
    Anyway, have reset the PRAM, still no luck. On the apple page regarding this procedure they mention a power management unit reset for ibooks...would this correspond at all to our problems? Is it something I should try or steer clear of?
    Okay. Resetting PRAM was a long shot, but worth trying. I would steer clear of trying to reset PMU. That is related to sleeping, waking and such things and your problems do not seem to be related to that. Also, I have never reset PMU, but from what I recall, it sounded a bit tricky.
    Am now attempting to reboot from backup. And yes, when I open Startup Manager, the internal hard drive DOES show up. If that means anything. Have a bootable backup (created with SuperDuper) which also shows up, but when I try to start up with it, I get stuck at blue screen (still.)
    As far as the iBook hard drive is concerned, this is a good sign. I am thinking that perhaps the hard drive is okay and the problem is something else.
    So, since the iBook originally came with Panther, and Leopard is really yet another unknown to throw into the loop, if I do another erase/install, I'm thinking Panther is the way to go? (Unfortunately we shared a family pack Tiger with a friend, and haven't got a hold of that install disc yet, otherwise I'd try Tiger, since it's what it was running and so is what the backup is, too.)
    From what I have seen in the forums, when people are having startup problems, the last resort solution usually works. That is, they take the install disk that came with the machine (Panther in your case), erase and zero out the hard drive and then re-install. That usually seems to do the trick. What they have probably done is either replaced some corrupted piece of software or fixed a directory problem on the disk. In your case, you have already done most of this except not with the Panther disk. So, I think it is worth going through this effort with Panther. If this actually worked, then you could worry about how to update your software to where you want it to be. If it does not work, I would consider this more evidence that there is probably a hardware issue.
    If this doesn't work (and would probably have to try in target mode again if the install disc won't open...) should I buy Tech Tool or Disk Warrior or just send it in for repair? I suppose there's a point at which I'll have to admit defeat!
    Not sure that I caught this before. You imply that the install disk will not open if it is inserted into the iBook. Is this a problem that showed up when the blue screen business started? When you insert the disk into the iBook and then reboot that computer from the disk (pressing the C key during startup), do you get something on the desktop?
    If, when repairing the hard drive with Disk Utility, you had received a message that the disk was not repaired, then a stronger utility would be a reasonable choice. But, that does not seem to be your situation. So, if it were me, I would probably not buy Tech Tool or Disk Warrior at this point. I do think that it is possible that these utilities might be able to do more troubleshooting than you can do with Disk Utility and the Apple hardware CD. Tech Tool in particular has some hardware testing capability. So, if money were no object, you might buy that and see if it can give you more detailed diagnostic information. Of course, these are purely my opinions. I could be totally wrong on any of this.
    Oh yeah, I don't know if I mentioned this earlier or not but all the restarts yesterday were accompanied be a brief "whooshing" sound (like a fan) for a second or so, and once I got both that sound and a "boooooop" issuing from the innards. Not sure if this means anything or not, but thought I'd mention it. Maybe the hard drive is melting! (Also I get further along the startup route after it's been turned off for a while.)
    This is worth mentioning and I overlooked it in your previous posts. The "booooooop" sound got my attention. When the computer is started up, one of the first things that is done is that there are some hardware tests performed. Apple does use some sounds to indicate certain problems. You can learn a little more at You hear "breaking glass" or "musical beeps" when you turn on your Mac. I don't know if you are hearing one of these sounds or if they are unrelated. But, I think that the "boooooop" sound in particular might be trying to tell you something.
    Let me sum up my opinions (which could be dead wrong). I still suspect a hardware problem. However, maybe the hard drive is okay. I think it would be worth using the Panther CD to do another erase and install on the iBook. If you still do not have a working computer, it is probably time to seek professional help. (However, if you get to this point, it is conceivable that you could be having some problems with your RAM chips. If you have worked with RAM chips before, you could try to play games with them: reseating them and removing them one by one- if you have two chips. But, if you have not done this before and are do not have some familiarity with working on hardware of this nature, perhaps you should just leave this alone.)
    If you need to seek some professional help, you might be able to try one of these options - If you have AppleCare, you should definitely give them a call. If you live close enough to an Apple store, you could take your computer to the genius bar and see if they can help.
    Sorry that you are having such a hassle,
    Rich

  • I see a blank blue screen at startup

    I see a blank blue screen at startup. Am I going to lose everything that I didn't backup?

    So I booted off the install disc (hold C at startup), did an archive and install) and then shut it down. Powered it up and zapped the PRAM at startup (commandoption+PR) and it now boots instantly. Just curious as to what video card you have in yours? I've been reading a lot of threads about problems caused by the ATI Radeon HD 2600, which is what I have in mine. Sounds as if a firmware update is needed, but not yet available. I also had 4 kernel panics in my first 20 starts. Apple Genius Bar said this was due to Symantec Anti-Virus for Mac.

  • 'Famous' blue screen at startup AND safe mode boot failure

    Dear all,
    Two days ago, after installing the new Java update/airport update and restarting, I encountered a 'blue screen' on startup after getting past the mac symbol and swirling cog. I cannot say whether the updates were the cause (doubtful) of if my cheap USB mouse that was still plugged it caused it or whether i have the dreaded 'bad sectors.' The cause aside, here is what i've tried to fix the issue:
    1) Disk Utility - Verification (OK'd) and Repairs (fine)
    2) Disk Utility - Verification of Permissions (a few needed to be done) All repaired
    -blue screen-
    -Restart after period-
    3) Rebooting in safe mode, removing startup items from the login items settings menu
    4) Removing startup items from System/Library/StartupItems folders
    5) Remove airport extensions (recent - date modified in list view)
    (NB - safe mode i could say my desktop perfectl in original form and all files!)
    -Restart-
    -no longer able to start in safe mode-
    -blue screen remains-
    6)Single User mode -
    resetting preference files (loginwindow.plist and windowserver.plist)
    Finally system profiler from Tiger DVD states:
    *Permissions repaired
    *Dependency errors: com.apple.iokit.IOUSBFamily & com.apple.kernel.iokit no valid version found
    *Integrity: kext has no receipt
    I backed up most my data from the LAST crash, but recent music/1000 photos and others have been backed up altho i've been meaning to! Help!
    I'M PANICKING now can no longer get in SAFE MODE!!
    Please help Mac911!!!!

    G3 iBook 800mhz   Mac OS X (10.4.6)  

    Update:
    So, I managed to do ALL that you said, EXCEPT, the reboot and work fine business.
    I created the admin account which works fine. So now I can see three user accounts (looks like there as already an admin type one).
    The one I created works fine, only, I can only access/see the login screen through a safe boot, (otherwise blue screens...) . I can get into the admin account fine, but when restarting and logging in as my original user account it won't boot. Something is very wrong in MY user account. I think at this point my data there is still retrievable somehow for a backup, clean start. but i haven't reached that point yet.
    Anyone have any clues what migt have caused the error in my user login?
    One of the things I tried (too hastily now i admit) first was to remove the recently added updates from the extensions folder. has this exacerbated the problem? Can i put them back without logging in as me??
    remember from my first post system profiler says software/extensions integrity 'kext has no receipt' and dependency errors: 'com.apple.iokit.IOUSBFamily and com.apple.kernel.iokit; no valid version found' - whereas in my newly created admin account it appears AOK.
    is this the source?
    any ideas anyone?
    sorry lots of queries here but i am ever hopeful.....
    All yours,

  • IMac G5 ALS hanging at blue screen

    Hi -- I've read variations on this problem, so hopefully I can provide enough information to get a solid thread started.
    On startup, my iMac G5 hangs at the blue screen. I've run the install discs, repaired permissions, checked the drive, all successful. Also tried the AppleCare CD, Techtool said all systems passed inspection.
    I can boot in safe mode, no problems there.
    I tried archive and install, but after restart had the same trouble.
    I tried booting in single-user mode to see what the log revealed, and the system seems to hang at the following:
    airport link active
    in6is_addrmulticast = 0
    flags = 0 fails
    can't assign requested address
    wide area service discovery disabled to avoid crashing defective DNS relays 192.68.1.1
    workaround Bonjour unknown error = 0
    I notice that some of the wifi networks in my apartment complex are recognized in single-user mode just before the system hangs, which is odd.
    I've tried applejack to repair the cache and preferences, but no progress.
    Next step appears to be wiping the drive and reinstalling the OS, but thought I'd check here first. Thanks!

    I altered the TCP/IP settings, but still no luck, so I proceeded with a full erase and install of 10.4. Much to my dismay, the system still refused to boot after the installation was complete.
    At this point I'd run across some threads discussing the capacitor cap failures of the iMac G5's, so on that hunch I popped the back off to take a look.
    One of the capacitors is indeed leaking out of the top, so I'm taking the unit in to the Apple store today to receive what will mostly likely be a death certificate. This unit is a refurb and the extended repair program ended in Dec. 2008, so I'm thinking my options are limited.
    I'll post back with the Apple store response just in case anyone might find it useful in the future.

  • IBook G4 Freezes at Blue Screen During Startup.

    iBook G4 933 MHz
    Mac OS X 10.4. Tiger
    640MB RAM
    40GB internal ATA hard drive
    Computer boots but then quickly locks up.
    If I immediately restart, then the iBook hangs at the blue screen before the Mac OS X progress screen appears.
    If I remove the battery and unplug the power cord then allow the computer to sit for at least 30 minutes, able to fully boot, but then the machine quickly freezes up.
    I assume the problem is heat related?
    I have so far:
    - Totally disassembled/reassembled
    - Reset PRAM
    - Reset NVRAM
    - Reset PMU
    - Unable to do target disk mode
    - iBook freezes same way when booting to Mac OS X install DVD
    Able to boot to shell command line mode no problem.
    FSCK reports no issues with the HDD.
    Sometimes during startup a fan turns on briefly, but not every attempt to boot.
    Yes-- I know about the 'solder' issues with iBook G4 logic boards, but I do not think the above is related. The VGA works fine.
    Thanks for any assistance that can be rendered.

    After a month, I have been notified by Superior Reball that the logic board has been repaired. I promptly made payment of $35 and the board was shipped back to me on June 17 via USPS Priority Mail Delivery Confirmation. I have received the tracking number and anticipate receiving the package by June 20.
    In my situation, well worth the wait for only $35.
    Even though I chose to totally disassemble the iBook, Superior will do the disassemble/reassemble for $75.
    I would not have done it by shipping the entire iBook, though. With the higher shipping cost, insurance, having to send out the hard drive with no back up, the higher repair cost, etc.-- in the end a prohibitive expense. I could probably buy a used iBook G4 for no more than $200, to put things in perspective.
    In summary, Superior Reball had a great price, good enough communication (they answer the phone, but not e-mail) and it looks like fast return shipping. It took a lot longer than the ad states, so I am applying the old 'price, speed, quality-- choose any two' rule here.

  • 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.

  • Radeon 9800 pro 256mb hanging on blue screen

    I'm deep in the waters of frustration right now, and am hoping someone here might have the answer.
    About 3 months ago I was looking for a video card for me to run motion. I saw the 9800 mac special edition with 128mb video ram had rave reviews. At that time ATI was not making them. So I turned to eBay...
    I purchased a card that was advertised as a Mac 9800 pro special editing 128mb. I later found out it was a flashed pc card. The ebay seller told me the card worked fine on all his mac's that he tested it on.
    The problem I was having was the machine boots up, I see the grey screen with the Apple logo and spinning wheel. I see the blue screen where normally I see the login progress bar loading the OS. But with this card I only see the blue screen. I hear the hard drive churning, so I am assuming it is still loading the OS, but I cannot see anything. I can reboot in safe mode and the video card works fine.
    Well... I assumed it was the fault of the card and that it was flashed. I returned the card to the ebay seller, who sent me another one, same results with that one. I returned the card to the seller and he refunded my money.
    I put the money toward the just released Radeon 9800 Pro Mac Edition 256mb card. I just got it a couple days ago and am experiencing the same problems. I have tried everything... everything I know and still can't get the card to work? Here is a list of what I have done:
    With the flashed card:
    1. Shut off computer and unplugged it. Removed OEM video card and installed ATI 9800 card. Plugged the power supply cable for the card into the computer power supply cable and hard drive.
    Problem Occurs: When starting up, the grey screen comes up with the Apple on it, then the screen turns blue, where I typically would see the progress bar of the system loaded up before the user login screen. I only see a blue screen at this point but can hear the hard drive working for about a min.
    2. Restarted the computer in safe mode.
    3. Logged in as Admin user and opened the ATI preference pane to verify it sees the card.
    When the ATI preference pane was loaded the following error message occured:
    A startup problem has occured.
    Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
    Clicked OK and the ATI preference pane appears.
    4. Close the preference pane and reinstalled ATI Displays 4.5.6. Restarted computer.
    Problem Occurs
    5. Restarted computer holding down AppleOption+PR to clear PRAM. Cleared the PRAM 4 times in a row, by allowing the chime to happen 4 times.
    Problem Occurs
    6. Shut computer down. Disconnected the DVI plug for the cinema display and connected a VGA CRT monitor. Started computer.
    Problem Occurs
    7. Shut computer down, disconnected the VGA CRT monitor. Reconnected DVI plug and restarted computer.
    Problem Occurs
    8. Started the computer in safe mode. Logged into admin account. Opened the ATI Preference pane.
    When the ATI preference pane was loaded the following error message occured:
    A startup problem has occured.
    Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
    Closed preference pane.
    Went to ATI site and downloaded:
    aug2005-radeo-universal-rom-update.dmg
    Ran the updater.
    Restarted computer.
    Problem Occurs.
    9. Restarted the computer in safe mode. Changed the login preference pannel to automatically log into the administrator account. Restarted computer, waited for the blue screen, then walked away for about 2 hours with the computer on blue screen, hoping the system was loading or doing something.
    Problem Occurs.
    10. Put in the TechTools Pro CD, hoping to run some tests on the video card from the cd. When booting from the CD OS...
    Problem Occurs.
    11. Enabled Root user. Logged in as root and installed ATI Displays 4.5.6 from there. Restarted computer.
    Problem Occurs.
    12. Shut down computer and installed old video card.
    13. On an internal hard drive in the computer. Wiped the drive and formatted it. Installed 10.4.1 on the drive. booted up into the drive, installed ATI drivers, shut down computer, installed 9800 pro video card, booted up.
    Problem Occurs.
    With the new 9800 for Mac ATI card with 256mb:
    With original card, install drivers, repairpermissions, shut down, install new card
    Set to restart in single user, give 5 min to see if ATI monitor startup item in user starteputems loads
    Hooked VGA & DVIt in together, both showed blue screen
    Reset NVRAM via open firmware
    Reset cuda button
    Take battery out, wait at least 10 min, re-install new battery, press cuda button
    Reinstall ATI update 4.5.6
    Reset nvram from open firmware
    In ATI control panel, selected 'Force Single Display Operation'
    Change display scaling to 50%
    Download latest Mac OS update from apple & reinstall
    Help?

    I get dizzy just thinking about it.
    I have tried installed a brand new OS, 3 different times on a different Hard Drive, still the card doesn't work.
    I had one person suggest that it may be the card is not communicating with the OS Window Drawing module? (excuse my ignorance of what that is really called. I just know there is some program, possibly in the kernel, that is responsible for drawing out the OS windows.)
    How can we rule out that it is a bad AGP slot?
    •The slot works fine with my 9000.
    •It works in safe mode with the 9800.
    •I have installed a brand new OS, three different times, still doesn't work.
    •I have used Apple Hardware test to test my hardware, the AGP slot didn't report any problems.
    I am assuming that the AGP slot is working. Although I worry about it a bit, because by now I have swapped cards in it about 50 times in my troubleshooting.
    Here is a link to a complete list of everything I have tried:

  • Blue screen and "startup disc is full" error

    My iPad2 is frozen with an "unaable to download app.....' error and after unsuccessfully trying to turn it off, I attached it to my MacBook Pro to try to sync it.  Nothing happened so i restarted my Macbook Pro.  Upon start up, the MP screen went blue and the error message "Your Startup disk is full" appeared. I hit OK & was left with a blue screen. 
    After disconnecting the ipad2 from the MP and restarting the Mp, same issue appeared.  Turned MP off and started in single user mode (Cmd-S).  Typed 'reboot'. came back up again with blue screen. 
    Tried single user mode again & typed 'fsck -fy'. System ran a checking routine and came back with "**The volume MacIntosh HD appears to be OK".  Entered 'shutdown -r now' to same results - blue screen , start up full -
    Now what?
    Looks like I'm running Mac OS X, 10.6.8
    when I go to start up ion via the option key network startup has a ? Mark.  Chose the startup with Mac OS...
    Same blue screen & error message
    I can get to system preferences using the option key but that's it

    I understand CS4 does like to use a lot of space for scratch space when making complicated image changes. Verify you are able to control how much scratch space it uses in such functions. If you aren't, maybe it is indicative of needing a separate partition or hard drive to store CS4 temporary drive. When you have a separate partition or hard drive, you can erase the drive, and avoid fragmentation of files larger than 20 MB. Normally Mac OS X doesn't suffer fragmentation, except with large files as explained here*:
