Problem: Mac won't boot up after upgrade to 10.5.4

Upgraded MacBook Air (SSD model) to 10.5.4 last night. Got a couple of boots where MBA showed a grey panel in the centre of the screen (in 4 languages) saying that I needed to restart my computer. On the third try got the white Apple startup, then a plain light blue screen. I know from previous upgrades that can sit for a while, so I left it overnight. In the morning, still blue. Power off, power on, grey panel telling me to restart again. Seems to be in a cycle of twice with a grey box, then the blue screen. Any ideas?
Everything is backed up, so if I get it sort-of working, I can restore to my last good 10.5.3 and take it from there.

Hi,
it happened to me too.
I've G4 mini with 1Gb RAM: with 10.5.3 everything was working fine.
Once upgraded to 10.5.4 and reboot, the Mac just won't start: blue screen with mouse cursor but nothing more.
Additionally, the mac becomes extremely noisy as for some process taking out all the CPU.
It's the second time I got a system failure after upgrading Leopard: this starts to be annoying.

  • My Mac won't shut down after upgrading to Panther

    I recently upgraded to Panther 10.3 from Jaguar 10.2.9. After Panther had installed successfully, I used software update and I'm now running Panther 10.3.9. However, since then my Mac won't shut down. It doesn't hang or freeze - it just does nothing at all.
    I've made sure no applications are running or have frozen. I've tried booting up from the OS X disk and running Disk Repair, and I've also tried using the 'fsck' tool. (I entered '/sbin/fsck -f' in single-user mode). Nothing has worked.
    Now each time I want to shut down, I have to force shut down. Can anyone help?
    800 MHz PowerPC G4   Mac OS X (10.3.9)   1.5 GB SDRAM

    Hard shutdowns can cause disk damage. You are better off leaving your Mac on until the problem is sorted.
    Have you disconnected all peripheral devices (unmount firewire drives before disconnecting) except Apple keyboard and mouse and tried shutdown? Often peripherals can kick back a signal to the cpu preventing shutdown.

  • Mac won't come up after upgrading to itunes 8.1.1

    My PB failed to restart after installing the 8.1.1 iTunes upgrade. I yanked the battery and tried again. It came up once. I started the activity monitor, tried to switch back to the finder, it locked up and I haven't been able to get it to come up since. It'll grind the disk away for awhile and then just sit there with a gray or black screen. I've hit command-control-power a couple of times, another couple of times I got the "you must restart your computer" multilingual message. What's my next move? I have an external drive under Time Machine control. Should I try starting from the Leopard DVD? What would I do then?

    Same problem here. A while after upgrading iTunes, my computer got completely frozen, so I had to make a hard reset.
    Since then my Mac didn't boot up anymore, it always got stuck at the grey screen, showing a flashing folder with a question mark, instead of the apple logo. I tried the usual (pulling all the plugs, resetting the PRAM...) with no luck, after I finally called the AppleCare hotline where they told me that I have to reset the PRAM twice in a row.
    That did the trick and my computer it's booting up again, but it keeps freezing randomly and I "losing the hard drive" whenever I do a hard reset.
    Any advice?

  • Playbook won't boot up after upgrade?

    I upgraded to the new OS 2.0 today and now my playbook won't boot up?  What's going on??

    You need to follow these instructions to "debrick" your PlayBook:
    You should have the Desktop Software version 7 installed on your PC, can be downloaded from http://us.blackberry.com/apps-software/desktop/
    1. Make sure your PlayBook is powered off (sounds like yours might already be) press and hold down the power button until the unit forces the device off.
    2. With the Desktop Software open on your computer and the PlayBook powered off, connect the PlayBook to your computer.
    3. You should see an error screen from Desktop Software popup with the options to Retry, Update, or Cancel.
    Very quickly choose the Update option.
    4. Once this is complete your PlayBook will go back through the initial (as if new) setup wizard (entering the BlackBerryID, etc.), and then you can perform a restore using Desktop Software to return your personal data from the backup. Applications which you downloaded from AppWorld won't restore, but they can be easily reinstalled using AppWorld >  My World section of AppWorld.

    I wanted to get Windows 7 on my Mac, so I got the disc, ran boot camp assistant, and when it said install Windows 7, I put the disc in, and clicked continue. The Mac reset, and after it got past the white screen, it went black, and my keyboard and mouse stopped working. Now I can't take the disc out because it won't let me go to my desktop.

  • Mac won't boot after power chord became unplugged accidently.

    Mac won't boot after power chord became unplugged accidently.
    I have a Mac Mini running very latest version of OSX. I was making a recording with QuickTime; when I needed to plug in a USB recording device into the back of the Mac Mini, as I pulled the Mac off my shelf to do this, the power cable came out and the Mac lost power.
    I plugged it back in and powered up the Mac. I get the grey screen with Apple logo and the spinning grey wheel; then it goes to a blue screen (as usual) and I get the "starting OSX..." progress bar. When the progress bar finishes, I'm left with a blue screen only, no dock, no apple icon at top left, nothing across the top, no nothing.
    So far, I've booted from the original disc and repaired the permissions as well as the disc, then re-booted, but same old blue screen.
    I have another iMac G5 machine, so is there any way I can at least retrieve the important HD files from the Mac Mini to my G5, before throwing the broken Mac Mini away?
    Can anyone advise please?

    Hi, Nigel.
    Not to differ with my colleagues here, but there's an important question that wasn't asked.
    1. You wrote: "So far, I've booted from the original disc and repaired the permissions as well as the disc, then re-booted, but same old blue screen."Did Disk Utility report any errors it could not fix when you ran Repair Disk? I suggest you run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
    2. You may also want to run the Apple Hardware Test that came with your Mini to be sure nothing shorted when the power cable was removed from the computer. I've seen it happen, hence I usually recommend removing the power cable at the wall before disconnecting the power cable from the computer. See my "Apple Hardware Test" FAQ.
    3. Repair Disk gives your Mini a clean bill of health, the blue screen may be the result of some Startup or Login item that was corrupted due to the sudden power outage. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem and may help you avoid and Archive and Install.
    4. If you elect to go the Archive and Install route, see my "General advice on performing an Archive and Install" FAQ for some important tips on this process.
    5. As FYI, this is the kind of problem that makes one glad they've implemented a comprehensive backup and recovery solution. For advice on the backup and recovery solution I employ, see my "Backup and Recovery" FAQ. Computing without a comprehensive backup and recovery solution is like driving without auto insurance.
    Good luck!

  • Mac OSx won't boot up after update to 10.6.7?

    Mac OSx won't boot up after update to 10.6.7?

    Hi Mike
    This is called a kernel panic, similar to s 'blue screen of death' on Windows. When you say you reinstalled 3 times, do you mean the OS or the Update?
    When does this kernel panic appear? You may have a hardware issue if it's happening on boot.

    tigerswim, welcome to Apple Discussions.
    Did you already have Tiger installed or did you have Panther 10.3 installed? Tiger is not a free upgrade; you have to buy it & then update (for free) using the download updates from Apple. Also, you have to use a universal/retail install DVD (or CDs) to install Tiger. You cannot use the install DVD from another model Mac.

    It sounds like you're seeing a startup issue with your Mac, it's booting to a gray screen with an Apple logo. Try the suggestions in the article linked below, they will resolve most issues related to starting up your Mac.

  • Mac won't re-start after going to sleep

    Since installing a new version of FaxstfPro (version 10.7), my MAC won't re-start after going to sleep. I have to re-boot to get the system started again.
    Thanks for any ideas on how to re-store the sleep fucntion.

    Thanks for the excellent tip. From reading the bluetooth advisories, I realized that my D-link was incorrectly installed in a UBS hub. Moving it to a direct UBS port resolved the problem.
    During the trouble shooting process, I found that I do not have a Bluetooth setup assistant. I have recently installed OS X 10.4.6 and also applied the Bluetooth firmware update, but I can not find the Bluetooth setup assistant in Utilites, and a search via Finder didn't locate it either. And I can't find the software in the .Mac downloads.
    Any suggestions on how to restore the assistant?

  • Problem updating to iphoto 9.6 after upgrading to Yoesmite  I am getting the following message when I try top date iPhoto This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or canc

    problem updating to iphoto 9.6 after upgrading to Yoesmite  I am getting the following message when I try top date iPhoto This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or canc

    "This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled." ?
    This error message will appear erraneously, if you skipped the update to Mavericks and iPhoto 9.5.1 and went straight from an earlier MacOS X version to Yosemite, without first updating to iPhoto 9.5.1 and associating iPhoto to your AppleID.
    Try first to buy iPhoto with your AppleID instead of updating. Delete iPhoto from Applications, but don't empty the Trash, then go to the main page of the App Store and search for iPhoto. If you are lucky, it will show as free and you can buy it directly.
    If iPhoto  is not showing as free, there is no help but contacting the App Store Support: Ask for a redemption code. You will need to provide a prove of purchase for your mac with iPhoto preinstalled.

  • My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive.  Can't get it to run Hardware Test.  Disk Utility says disk OK - files are there. What can I do?

    My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard.   I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host.  But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning.  I can't get it to run Hardware Test - just get the white screen.  If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

    Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
    clean the disk.
    If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

  • Mac won't boot, stuck on grey screen if the external hdd plugged in

    as the title.
    if i plug my external drive, via usb port, the mac won't boot and stuck at grey screen.
    unplugging it, the boot process will continue.
    the hdd is a LaCie mobile hdd
    any help?

    Hello jason(?)
    It's a LaCie external mobiel hdd, formatted as exFAT. without adapter. take power directly from usb port.
    i tested it on my iMac and it works fine. boot up as normal. the only difference is my iMac is on 10.6.8 and my Air is on 10.7.2
    I tested on both USB port on my Air and the problem still persist.
    the read/write speed is normal (bought it like a day ago).
    another thing is I don't have this problem with my external WD drive.
    One thing to notice is that, I accidentally left like for like 2-3 mins and it boots. So why the question now is why it's taking so long to boot? normally it just takes <20 seconds. Seems like it tried to boot from the external hdd, doesn't it?

  • My mac won't boot up..  I've tried PRAM resets and fsck.

    My mac won't boot up anymore. This problem started quite randomly, as I had just used my mac an hour a go. At first, it just wouldn't finish loading up, but now it loads up for a bit, then suddenly shuts down. I've tried resetting my PRAM and using fsck but nothings worked. Any ideas what could be wrong?

    Yes I have seen a similar problem quite recently, and ended up having to perform a software reinstallation as not even Disk Warrior could see the Hard Disk.
    Before you go to that extreme insert your System Disk 1, reboot holding down the "C" key and go through the first two steps until the "Utilities" menu appears on the top left of your screen.
    Select Disk Utility and (assuming your hard disk appears) click on it and select the "First Aid" tab > Repair Disk.

    My mac won't boot up it goes to a apple sign then the spin thing then gives me a error msg on a 10.5.8 imac what do I do?

    Hi LIsa,
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, 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 at top of the screen. (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. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a 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 completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    Or..
    Tough without the Install Disk problems, but try fsck...
    To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
    1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup.
    Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
    2. At the command-line prompt, type /sbin/fsck -fy
    (SPACE between fsck AND -fy important)
    3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
    The volume (name_of_volume) appears to be OK
    If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
    ***** FILE SYSTEM WAS MODIFIED *****
    Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
    4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
