iMac dies after Safari update

iMac cannot boot after installing Safari update.

There is a new Safari update. After I installed it, my home iMac cannot reboot.

For about an hour, the iMac was stuck in the grey Apple screen (sometimes with, and sometimes without, a progress bar). The progress bar would “finish,” then the Mac would restart back into the grey Apple screen.

I decided to leave the iMac alone while I worked out.

When I returned two hours later, the iMac had progressed from the grey screen to a blue screen. Zapping PRAM and restarting gets me a grey Apple screen followed by a blue screen. The blue screen flashes twice while changing its color balance settings, indicating that some part of the operating system still works. Then a tiny white rectangle appears at the top left of the screen. Then, nothing further.

This machine contains my entire music collection and all my photos of my daughter.

I have a backup drive but cannot force the iMac to boot from it.

I have an OS X CD but cannot force the iMac to start from it.

Maybe this is what Apple means by “HTML5.”

  1. Are you sure you didn’t actually install the latest Flash Player? I doubt HTML5 would do that. Sounds more like Flash. Definitely.

    Seriously though, that sucks. Hopefully you can work it out so you don’t have to pay someone for data recovery on your hard drive. Losing data (especially photos/music) sucks big time.

  2. Hey Jeffrey,

    same thing happened to my brand new MBP core i7 last Monday. After the required reboot, my notebook got stuck on before the login screen. I tried to restore system files 3 times and nothing. Had to wipe the drive and re-install everything again. #majorFail.

  3. Most likely there is either an Internet Plugin that Safari5 is now taking issue with or one of the core components that Safari updated became corrupted. If you have a backup you can boot from, boot up the computer, and then on the hard drive that you upgraded, navigate to your home folder > Library > Internet Plugins. Delete the contents of that folder.Try rebooting.

    If you don’t have a backup to boot from, you can boot in to single user mode, and perform the same steps as above through the command line.

    If this doesn’t fix the glitch, most likely something was corrupted in the upgrade process, in which case you should roll back to backup if possible.

  4. I only what to copy/paste this brilliant comment:

    “Man, when macs crash they crash HARD.”

  5. Ditto on the drive failure. Something similar happened to myself about 2 months ago on my iMac and it ended up being a complete hard drive failure. Although I was able to boot via the OSX install dvd. So it smell of some other failure, good luck on recovering your data.

  6. i say it’s merely a coincidence of timing, suggestive of some hardware failure. but this “I have an OS X CD but cannot force the iMac to start from it.” is certainly quite odd. i’ve never not been able to start from a readable system disk. make an appt & carry it down to the apple store.

    also, if you plug your backup drive into another computer, you should be able to read for “latest” time machine backup as just an external drive with no problems.

    good luck.

  7. Almost sounds like a bad HDD issue but you aren’t getting the missing system folder problem. I don’t think it would be an Internet plugin conflict. If not a HDD issue, perhaps a missing system component or a permission screw up in the system optimization step of the system update process?

    The fact you can’t option key at boot to get the boot menu is just odd.

  8. Have you considered DiskWarrior? It will not boot on the iMac quad-cores but if your system can boot a copy, that would be a reasonable place to start.

  9. Hi Jeffrey,
    iMacs Super Drives are known for not last long.
    If you ever kept an old exernal DVD Drive, go with it.
    Good luck.

  10. Why would it be a HD failure. The lack of ability to boot from a DVD or external drive says motherboard failure. If you are near an Apple store head there.

  11. Sounds more like a FML5 problem mate.

    If you cant force the iMac to boot from the disk drive it could be a faulty logic board and a coincidence that it happened during the Safari update.

  12. I had something similar when I installed the 10.6.3. Turned out I had just hit a bad disk sector (HD was bad).

    How to test: Boot from the install CD and run disk utility. You can check disk from there…

  13. You could try booting in Safe Mode, too. (Boot + shift, I think. Like booting with extensions off in the old days.)

  14. Jeffrey,

    Try disconnecting everything but the keyboard and mouse and then try booting into single-user mode (details).

    I’ve had a very simlar problem as this on a G4 iMac, and the only way I can get it to boot is going into single user mode with all other peripherials disconnected.

    While it’s possible that the Safari 5 update caused an issue, it’s further likely there is something hardware-related going on, and it just reared its head after this reboot.

    Best of luck, and I hope you can get it up and running soon.

  15. I’m writing this from the backup drive connected to my iMac. By holding down the OPTION key, I was able to boot from the backup drive. Once booted, I used Disk Utility to perform a disk repair on the internal hard drive, then attempted to restart using the internal hard drive as a boot drive. Alas, repairing the drive did not fix it—the iMac still will not boot from its internal hard drive.

    So I’m back using the backup drive as a startup drive. I’ve lost some work and a bunch of music I bought yesterday at emusic.com, but I should be able to re-d0wnload that music from the website once everything’s working again.

    My next experiment will be to copy my backup drive to my internal hard drive using SuperDuper, the super-simple backup software that created the drive I’m now using. SuperDuper has never failed me.

    Once I’ve copied my backup drive to my internal hard drive, I’ll tell the Mac to use my internal hard drive as a startup drive, and I’ll try rebooting once more. If the machine is still stuck in the blue screen of death, I’ll know the internal hard drive is fried and unusable—and I’ll write off as a coincidence the fact that it failed during a restart immediately after installing the Safari update.

    By contrast, if the machine restarts from the internal hard drive after the SuperDuper cloning, I’ll know for certain that my iMac didn’t like something about the Safari update, and I will not download or install Apple software updates on this machine for the rest of its life.

    More will be revealed.

  16. Bah, sorry, messed up the link in the previous post.

    Try disconnecting everything but the keyboard and mouse and then try booting into single-user mode (http://support.apple.com/kb/HT1492).

  17. Can you get it to boot in Safe Mode? (hold shift down at boot)
    http://support.apple.com/kb/ht1455

    If not, try verbose mode – start the Mac up and hold down cmd+v, then see if you can glean any info from the information displayed before it reboots?

    How’ve you tried force the iMac to switch boot devices? Inserting the DVD immediately and having the USB drive connected, then booting and holding down Option (alt) _should_ present a list of available boot devices.

    If you can then boot into Safe Mode or boot from the OS disk, make Disk Utility your first port of call and run Verify Disk on your drive. This may be what’s preventing it from booting. Perhaps repairing the permissions (unlikely, but possible) for good measure, then try Ted’s suggestion of inspecting errant Safari Plugins.

    The Hardware Test may well be worth running to rule out an underlying fault, but unfortunately this will take a while to complete so I’d try the above steps first.
    http://support.apple.com/kb/HT1509

  18. I’ve had the same issue. If you unplug all of your peripherals except your keyboard and hard drive (what Chris Anderson said), you may find success. I’ve had that issue for about a year.

    I can’t figure out why Apple hasn’t fixed this issue yet.

  19. Hey, look, more helpful advice!

    Try booting from the internal drive while holding down CMD-V. It won’t help you get past the boot problem, but it’ll start your system in character mode so you’ll see the boot messages that you don’t normally see. The last message you see before everything stops moving will be a likely candidate for your gremlin.

    It’s worth a shot.

    E.

  20. Before cloning your backup drive to the iMac, just re-install the OS on the iMac. Snow Leopard should not kill anything. Additionally, you can always copy out your user directory to some other external folder, saving all your work, while booted off the backup drive, yes?

    But along the lines that other folks suggested:
    cmd-S during boot, and see if you get to the boot prompt. Then follow the directions there for the “fsck” command, reboot, do the cmd-S/fsck check again, and then reboot. (If the system can fix and work around bad disks, it should do that for you).

  21. Have you tried booting into a Darwin prompt? If you can do that, go ahead and run “/sbin/fsck -fy” once you’re at a command prompt to see if any repairs are needed on your volume. I thought I had killed my Mac after installing some VPN software that did some pretty low-level system changes, and booting up was the same experience for me.

  22. I am going through this same thing as my internal HD on my 20″ iMac crashed last week. I am not looking forward to replacing the internal drive myself as the process looks comparable to dismantling an atomic bomb.

  23. Jeffry, if you can boot off your backup then it’s probably not hardware related.

    Restoring with SuperDuper will work out for you – but you still need to see if you can figure out what caused this because I bet you’ll get it again when you update to Safari 5 if it’s due to some dusty plugin or software.

    As to Safari 5, folks who’ve had problems and posted crash reports seem to have installed things like SIMBL-based plugins or other outdated extensions that have always been “hacks”, i.e. unsupported by Apple.

    One guy on Apple’s forums had just gotten his first Mac coming over from Windows and he claimed he’d installed nothing but once he posted his detailed crash log it showed he’d installed a bunch of unsupported software.

    If you’ve migrated this system from older OS X versions you probably still have some gunk that a WebKit update choked on. This means doing a “deep clean”, by hand. If you’re not comfy weeding around in the core system folders removing things you might want to wait and see if this comes to light before updating.

  24. Sorry, much of what I posted above was made redundant in the time it took to write it :)

    I’d still recommend running the Apple Hardware Test and performing the extended test (including the drive diagnostic). As an aside, do *not* rely on the SMART status of your drive to accurately report its health. If SMART reports that it’s failing then yes, it is failing, but I’ve seen many drives die with no prior SMART warning whatsoever.

    Overkill perhaps, but it’d definitely be worth knowing with some authority the state of the internal drive before you clone your backup back to it and trust it with your data again.

  25. Practice better computer hygiene with your personal files! I would have expected you to have had the personal data both archived and backed up on two different hard drives, one off site. If you do not learn, you will repeat this.

  26. Success! After restoring from SuperDuper, I’m able to once again boot from my internal hard drive. I’m writing this from my iMac’s internal hard drive, where I’m currently re-downloading from emusic the music I bought yesterday—namely, Minor Threat: First Two 7″s, Outkast: Speakerboxxx/The Love Below, Sleigh Bells: Treats, and Prince: The Hits 2. Gotta love that re-download feature at emusic.com.

    you still need to see if you can figure out what caused this because I bet you’ll get it again when you update to Safari 5

    Indeed! I plan *not* to update to Safari 5 for the time being. Weird position for a web designer to be in, but it’s better to have a working machine than no machine.

    FWIW I do not use *any* plug-ins in Safari except Click2Flash, a Flash blocker.

    Could the existence of a Click2Flash plug-in in a library folder prevent my iMac from booting? It seems unlikely. Yet I also would have thought it unlikely that a browser update would wreck my iMac.

  27. If you’ve migrated this system from older OS X versions you probably still have some gunk that a WebKit update choked on.

    Nailed.

    I can probably install Safari 5 just fine on my laptop, which was never migrated from any previous machine.

    But my iMacs made use of Apple’s Migration Assistant—as why would they not? It’s a feature Apple promotes. Which means there is old gunk in there, because Migration Assistant is not as smart as it could be, especially w/r/t fonts that don’t come from Apple, software that doesn’t come from Apple, and so on. Which means updating my browser on these machines is a recipe for prison love. So.

    The nice thing about the iPad is that you can’t be a power user. It’s primarily power users like me and @hotdogsladies who get screwed every time Apple creates a system update for an imaginary world where the user has never installed anything but Apple software.

  28. Can you do an “Archive & Install” form the Boot DVD (boot it with the Option key trick used to boot your External.)

    this should fix anything and get you back up and running with no data loss (except you’ll need to do all the OS updates again)

    Ben

  29. Hi, Jeffrey –

    (All of this should be taken with a hefty “he is talking out of his hat” in mind)

    For the record, I’m fairly certain the “blue screen o’ death” happens (usually) because the OS isn’t able to rebuild the extensions cache after installing something that goes into the system folder. I believe the best way to fix this without having to revert to backup is to force the system to rebuild its extension cache by “touching” the extensions folder.

    I know this this all technovomitus, but here we are.

    Fixing this without wiping or restoring from backup requires the terminal (I KNOW). I can post the steps if anyone is interested.

  30. Next time that hag in marketing that never shuts up about how Macs NEVER EVER have hardware problems opens her mouth in my direction, I will be shoving this URL in her mouth.

    Glad you have good backups. :)

  31. Unplug the power cable and let it sit for at least 15 seconds to reset the PMU. I had this same thing happen to me a while ago, and Apple support got me squared away.

  32. Seems like my first comment attempt got eaten, so I’m reposting. I hope this isn’t actually a duplicate:

    Unplug the power cable from the Mac for at least 15 seconds to reset the PMU. I had this same problem with a current 27″ iMac and Apple phone support took care of me right away.

  33. Ironically, Safari 5 runs just fine on my iMac at work, which was migrated from the same system. (I updated my studio machine to Safari 5 on June 10 and didn’t even know it.)

  34. This exact problem happened on my 2006 white imac (24″)

    I dunno what went wrong but I updated some junk and it just went nuts. I disconnected the disk (machine is out of warranty anyway) and plugged it into a PC. Booted the PC into HDDRegen and it reported a bunch of dead sectors. Fixed Those. Checked the vendor tools, “disk has problems but we can fix those” it said. Ok Fixed those.

    Disk is now “perfect” or so every tool tells me, I copied all 500gb of data over the eithernet to a usb disk (only way I could copy files larger than 2gb, damn fat32) without a hitch, but the imac will not boot from the disk. My OSX cd will not boot with that disk plugged in so I can’t even do any internal OSX tools to fix it. The machine just sits there showing a grey screen going “I’VE GIVEN UP.. ALL HOPE IS LOST..LOL”

    How did I fix it? I got a new disk and now the imac works. I have no idea what the problem is.

  35. Here’s the steps to possibly fix this issue:

    1. Boot your computer and immediately start holding down command+s. We’re booting into Single User Mode here.

    2. After a short delay, a bunch of text should appear on a black background. If it doesn’t, then you’re suffering from a different issue. When you see this text, you can release those keys.

    3. At the bottom of your screen should be flashing prompt. Type:

    mount -uw / and hit enter.

    4. Type:

    cd /System/Library and hit enter.

    5. Type:

    touch Extensions and hit enter.

    6. Type

    exit and hit enter. Your system should reboot.

    If you still get the blue screen after these steps, you’ve probably got a different issue on your hands.

    Hope this proves useful to someone – I had the same problem as Jeffrey after installing Safari 5 and this fixed it.

  36. I had the same problem as Jeffrey after installing Safari 5 and this fixed it.

    OMG I AM FRAMING THIS. Someone had the same problem with an Apple update as me!

    Thank you.

  37. Hi Jeffrey, I had the same problem on one of my mac pros (1 out of 5 machines) – and concur with the earlier post that it is related to caches not getting rebuilt correctly. I didn’t fix it by touching the extensions folder, but that would probably trigger a rebuild of the folders I list below as well.

    I zapped the Pram, and booted into single user mode. Then mounted the disk and deleted everything inside these folders:

    Hard Drive/Library/Caches
    Hard Drive/System/Library/Caches

    example:
    cd “/Library/Caches”
    sudo rm -r ./* (use caution with this obviously…)

  38. I suppose booting into safe mode (hold down shift) and then following the steps above in the finder should work too, if any of you are scared of the command line -

  39. Jeffrey,
    I just baked a standalone version of Safari 5 so I have both, Safari 4 and 5 for testing sites etc.
    I can email you a link to download it tomorrow if you like. Then you have it without needing to download the upgrade.
    My build is for 10.6.x only though, if that is what your iMac has installed.

  40. Happened to me too, after installing Safari 5, but starting in Safe Mode (SHIFT pressed at boot) and then rebooting in normal mode solved the problem.

  41. Hi Jeffrey,
    These pesky Macs – no more as they used to be… I haven’t had any problems with my iMac after I installed Safari 5 – or rather should I say any *supplementary* problems than the usual random freezing since the 10.6.3 update… Good luck with your iMac – hope your daughters’ photos aren’t lost…

  42. Jeffrey,

    I am having similar issues. I have a macPro tower that will be two years old in Sept. When my Computer sleeps for long periods of time (like while I’m at work) I come home to find a patchwork of black and speckled grey spread across both of my monitors that I can’t get out of. I reboot and it’s fine. This has happened the last two days in a row, and the only thing I downloaded in the update this week was Safari. Kind of weird! Good luck with your photos and music — that’s really rough. :(

  43. Happened to me too, after installing Safari 5, but starting in Safe Mode (SHIFT pressed at boot) and then rebooting in normal mode solved the problem.

    For the record this will work whenever you log in after a power failure or similar abrupt turning off when OS X hasn’t had the change to properly write out and “park” it’s caches. Safe boot is slow and you must restart again after successfully booting and logging in, otherwise some things won’t work – like sound.

    I get this every so often with the older G5 PowerMacs we still use at work. Amazon is building a new HQ a block away and the power gets cut a lot.

    Jeffry: I use ClickToFlash and it didn’t cause any problems on the handful of Macs I’ve updated (both PPC and Intel).

    I do recommend doing a DiskWarrior run (you do own this right?) on your restored system, especially if you plan to try updating again. Disk Utility won’t find everything DW can.

    Also, it might be a good idea to run SuperDuper before you install major Safari updates just to save a bit of hassle keeping up-to-date.

    You may have had a hiccup with a system cache from a permissions error or something obscure. But OS X has been so easy to migrate between updates that I’m now of the opinion that even a clean migration can pull over unwanted old software.

    I run the same migrated system I’ve had since the OS X Beta and at least three times I’ve had to clean it up by hand and weed out a little. Looking at the Console you’ll see all sorts of reminders to some demo or application that is still hanging around.

    Next time I upgrade my hardware I’m going to do a slow and painful clean install and carefully migrate only data.

  44. Just got the same problem with my 13″ white MacBook. After installing Safari 5 upgrade system starts up with Apple logo and progress bar, then progress bar disappears after some time, and system does not proceed with boot any further.

    Prior to upgrade (today) I rebooted the MacBook successfully several times.

    Now I successfully booted in single user mode and started fsck. It says my MacOS disk can not be repaired.

    Looks like this Safari update somehow corrupted my disk contents.

    Any suggestions on how can I try to fix it in single mode? I have no Installation disk with me right now.

  45. Started in Safe mode and i am back. Info from this site was a big help … thanks

  46. in reading this, i’m backing up my music collection (time machine currently doesn’t as the collection is almost 100 gigs)…

  47. Somebody please help me,

    I tried to upgrade Safari last wednesday. Since the upgrade, whenever I click on the safary icon, nothing comes up and after 30 seconds a message comes up with Safari quit unexpectedly.
    To add to this, I replaced my battery within the last year and that has completely died. There is 100 per cent life but as soon as i remove the charger my macbook pro cuts out completely.

    I have tried sending numerous reports when safari quits but no reply. I went on to the apple support website and it told me that i cannot contact them as somebody has been trying to use my system.

    I truly need to speak to somebody and sort this out as i have had the charger in my macbook pro with the green fully charged light on for 3 days now when i’ve been using it.

    I’m sorry if this is all garbled but i’m feeling really fed up, oh yes and my legs are burning as usual because this overheats too.

  48. p.s. I have an important interview on Wednesday and need my laptop for my presentation. i’m so worried that the thing will just not perform and i’ll be completely embarassed.

  49. Hey, I hope this is not a sign of things to come now that Apple is so incredibly huge. I have heard so much lately about their iron fist when it comes to what will and will not be acceptable for software submissions. Until now I had never heard of a MAC crashing….Could Apple become the next Microsoft (just a bad joke, please holster the rotten fruit)!

  50. This may help some others.
    I run my mac as guest in a Linux VMware host. There’s a VMware feature that you can use to snapshot your system, so you can revert anytime you like as far back as you have snapshots.
    I also wonder what would happen in single user mode if you checked the logs. I’m not a BSD guru but the information on why it wouldn’t boot is probably in /var/log/system.log Unix is great about logging, unlike windows. It would probably be good to check a book like this: http://oreilly.com/catalog/9780596009151?mybuyscid=11655006952&cmp=af-mybuy-9780596009151.IP

    I think I’ll go over to my Actually I’ll fire up a no-machine remote session to my VMware host and start my snow leopard in the NX remote session. (Rats, 3D graphics is disabled. No biggie, it still works.) I’ll update it (the Mac) and (take a VM snapshot before hand) see what happens.
    Update worked fine. http://tinypic.com/r/2zsv5t0/6
    Anyway, from a terminal type: less /var/log/system.log
    Hit enter.
    Spacebar moves forward a page, enter moves one line forward, pg-up and pg-dn are just that. q to quit.
    Enjoy

  51. The Safari update hung my computer (Mac Pro) at the blue screen, and I let it sit overnight to see if it could work out its problems. Unfortunately, when I woke up, it was still sitting on the blue screen, but thankfully, when I did a hard reset, it booted up and seems to be working fine. Until they acknowledge and fix the problem however, I’d definitely recommend holding off on the Safari update. (Thankfully my SuperDuper backup never really had me worried about loosing data. It was more of just an inconvenience thing.)

  52. Marcy:

    Safari’s crashing should not impact your presentation if you created your presentation in Keynote or Powerpoint. Copy your presentation (including fonts, if you use anything other than system fonts) to a jump drive, CD-ROM, or DVD-ROM so it can run on someone else’s computer if it has to.

    From what you are saying, your MacBook Pro will function as long as it is plugged in. So plug it in as soon as you arrive at your interview. (Of course, if you can borrow a friend’s laptop and copy your presentation to that laptop, so much the better.)

    After the interview, bring your MacBook Pro to the Apple store so they can fix the power problem.

    Before or after the interview (but after you’ve copied your presentation to a jump drive, CD-ROM, or DVD-ROM), if you’ve been running a backup program like Time Machine or SuperDuper, and you have a recent backup from *before* you updated Safari, restore your Mac to its previous state. You’ll have Safari 4 again and it will work. Don’t update to Safari 5 for the time being.

    If you don’t have a backup program, then tell the folks at the Apple store that Safari 5 is crashing on startup and has never run. They will know a trick or two to fix it (even if Apple isn’t announcing the problem).

    Good luck! :)

  53. The only fix is to use your right hand to push the letters “F” and “S” while your computer boots. It’ll flash the screen twice. Now, be prepared. You’re going to have to hum along, on beat, as the other 25 screen flashes come along. Then, your iPhone will ring. It’ll be Steve telling you he’s sorry. He’s going to remotly (godly) remote access your iMac and restore it back for good. Everything will be perfect.

    Seriously, my Aluminium iMac’s HD crashed back in december too. Couldn’t boot, either from a CD et internal HD. I was about to loose lots of pictures and work jobs. No hesitation there for me. I’d rather pay someone else 200$ and get everything back then to risk loosing all those precious memories and jobs.

    Your choice.

    Hope everything worked out good.

  54. Thanks for your replies guys. I am just worried about the fact that i paid £80 for this new battery charger last year and i may be wrecking it by keep the thing plugged in.

    I’ll let you know how it goes.

  55. THIS SAME THING HAPPENED TO ME… restarted my imac. When it tried to restart, it kept cycling through that blue screen that you had mentioned. I then tried to archive and reinstall OSX and it found the hd, but showed no progress for a very, very long time. I then did a hard shut off and tried again. The install disk could no longer see the install disk. It’s in the shop now. I’m almost positive that I installed Safari the same night that it happened. Maybe I’m just bad at computers.

  56. I’m a Windows user and I always hear that Mac’s don’t crash…guess they do! No one is safe from bad software

  57. Downloaded the Safari5 to find out that my Quick Books web based program was not ready for it. So am using Firefox to access QB.

  58. I think its some strange karmic thing happening. Steve Jobs snubbed Adobe, to put it politely, and see what happens. I mean how many people started their careers with Photoshop on a Mac? Next thing you’ll be telling me is you can run Microsoft Word on a Mac… oh wait what?

  59. My MacBookPro died as well. Installed the safari update and now I can not leave startup…no idea what to do. :-(

  60. Whoa your iMac crashed? I barely got the Safari 5 update like 1 hour ago
    and after i restarted my iMac and then i decided to get on the internet and now my iMac loads pages on the internet super slow! Im not used to having my pages load slow, come on i have an iMac it was super fast. I hope Apple tried resolving this problem . Hopefully …..

    i think the problem is the new update and stuff like the safari 5 is the reason all this occured i reegret getting this update, i still cant believe you iMac crashed call apple immediately !

  61. It was happened to me on my MacBook as well. I am hopeless now and tried to download Safari again but still the same . Please help me to revole this issue. Now I really nervous about new apple updates.

  62. My iMac also crashed after installing this update. Safari was running slowly but I didn’t think too much of it. Then it got stuck on the rainbow wheel trying to load a page. It wouldn’t force quit so I had to just use the power button to turn it off and when I started back up, it gets stuck on the grey screen with the flashing folder with a question mark on it. It won’t boot up from disc or I safe mood. And, no, it’s not under AppleCare anymore. I do have most things backed up, but there is a lot on that drive.

  63. The only thing that worked for me was:
    – running disk warrior
    – backing up all my documents on a external drive
    – and re-install OS X

    Great fun…Not

  64. Same happend on my macbook pro, my friends imac AND my flatmates macbook.

    same symptoms everything. luckily i have apple care. still not cool.

  65. after i downloaded safari,and other updates, on imac couple days ago, my safari won’t open any windows at all–can’t use it at all. firefox works. not sure if this is similar issue…please–if anyone knows how to fix…

    regarding “… It wouldn’t force quit so …”: I’m thinking you must have tried using the “Force Quit” command from the icon of the app that was “hanging”, is that right? All apps can be force quit. But the icon, in the Dock, of a hung app, is only displaying “Force Quit” because the Finder (and ‘launchd’) are ‘aware’ that the app is ‘hung.’ The app has no such self-awareness, so it’s dock icon might as well be an apple (oops) sitting in your fridge, as far as it’s concerned.

    Using Command-Alt-Esc, to get the ‘real’ “Force Quit Applications” window, is almost always the easiest way to really have the OS send a serious ‘kill’ signal to the app in question. You’ll see the app, listed in the Force Quit window, as being unresponsive. (I forget the term Apple uses). It’s real obvious, though. Select it in the list, hit the “Force Quit” button, and, usually, you’ll get an alert along the lines of “Are you sure?” that asks for an admin password. And that’s it.

    You can also force quit apps from the utility called, “Activity Monitor.” I’ll bail now, for space reasons, but Activity Monitor is cool for when multiple apps are freezing (it’s usually a sort of ‘cascade effect’ from one app trying to quit “gracefully”, failing, and other apps falling like dominoes. (Usually happens in a badly aborted “restart” or “Logout” routine. Open Activity Monitor, see all the processes that say “not responding”, and then use the built-in quit/force quit button to ‘kill’ whichever “unresponsive” app is using the most RAM. After that, the remaining, so-called ‘hung’ apps usually go back to active states, and keep functioning just fine.

  67. Wow, the same thing happened to my work laptop when I upgraded. I thought it was because I was on Leopard. My computer was on its way out anyway… but that’s the straw that broke the camel’s back I guess. IT said they weren’t able to recover anything… but on the plus side I finally got a laptop upgrade out of it! Thanks Apple!

  68. I had a similar problem, and once I removed the “entire internet plug ins” folder and imput managers folder all was OK; since you indicated you went from a grey to blue scren indicates the corruption of a k text file. Use Disk Warrior to “rebuild the directory, and boot from an external source; external drive Time Machine whatevr, then report back!
