Mac Mini 2008 stuck at boot stage (apple & rotating bars)

Hi Community, I read some of the comments from people in similar situations. It seems that I will try to boot up with a utility disk inside it. WHERE do I get that utility CD second hand if do not own one anymore?
I live in TW11.
Or any other advice?
Thanks,
Edoardo

If you no longer have the original OS X disks that came with the system, contact Apple support (not the local store), and, if they still have them in stock, they can sell you a new set.
If you want to run Disk Utility, if you have a retail version of OS X you may be able to boot to that, and click on utility on the menu bar to bring up Disk Utility.  The original OS X disks also have the Apple hardware test, which is the only place to get it. However, it you have either of the TechTool programs, they do similar testing.
Have you tried a safe start, where you start holding the shift key down? That sometimes can get a system going, and may take awhile to start. If it works, try a normal boot.

  • Mac Mini 2013 stuck on apple logo

    My Mac Mini is stuck on the apple logo with the spinner underneath it. I was running a program and put the computer to sleep. When I started it back up, the program was stuck. I couldn't get to the command options and shut it down. When it started back up, I typed in my password, but it continuously got stuck on all my account logins. I tried to safe boot it, but it just loads the progress bar and goes back to the logo and spinner, even if I leave it alone for half an hour. I tried to use the option button, but none of the options work. I tried unplugging everything but the monitor and turned off my Apple Bluetooth mouse. Still didn't work. It is a 2013 model, so it has no CD drive. PLEASE HELP! I need this working soon. If it is possible to migrate another Mac to fix it or migrate one onto the disk after I erase it, please let me know. If not, give me some advise. I need help ASAP. Thanks for your help!

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.   
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • Mac Mini keeps hanging during boot

    My ~3 year old Mac Mini keeps freezing during booting with the error message "You need to restart your computer. Hold down the Power button...". This happens every time. Booting in safe mode works.
    This happened with Mac OS X Tiger but keeps happening even after I have completely reformatted that hard disk and reinstalled Leopard from scratch. There are no external devices connected to the computer besides the monitor and a bluetooth mouse and keyboard.
    After reading some discussion forums I have already tried starting into Open Bootware and running "reset-nvram" and "reset-all" but to no avail.

    Welcome to Apple Discussions!
    What you are suffering is a Kernel Panic, and given you have reformatted your drive and reinstalled MacOS, it would tend to suggest the issue is hardware related - most common culprit being RAM.
    http://docs.info.apple.com/article.html?artnum=106227 explains what kernel panics are, and http://www.thexlab.com/faqs/kernelpanics.html and http://www.index-site.com/kernelpanic.html may give some assistance in working through the problem to determine the cause.
    The one good thing is that your system appears sufficiently stable to allow you to boot to the Leopard installer and complete a full install. This makes it less likely there is a fundamental issue with the most expensive component of the system, the logic board.

  • Have an old mac mini 2008 running OS x 10.6 whenever I shut down or restart it wont find the dell screen again. have tried with different screen same result. have revived it before by unplugging all cables zapping PRAM and starting in safe mode

    Have an old mac mini 2008 running OS x 10.6 Whenever I shut down or restart it won't find the dell screen again. Have tried with different screen same result. Have revived it before by unplugging all cables zapping PRAM and starting in safe mode but no luck now. It has all my daughters exam work on it which she, of course, has not backed up so any suggestions gratefully received.

  • My Mac mini is stuck in a reboot screen that is all white with a grey folder with a question mark in it

    My Mac mini is stuck in reboot screen that's
    white with a grey folder in the middle that blinks
    and there is a white ? mark on it. What do I do ?

    There are four general causes of this issue:
    1. The computer's PRAM no longer contains a valid startup disk setting when there aren't any problems with the disk itself. This can be checked for by pressing the Option key and seeing if the drive appears.
    2. The internal drive's directory structure has become damaged. This requires usage of an alternate bootable system to perform the repair.
    3. Critical system files have been deleted. This requires usage of an alternate bootable system to reinstall them.
    4. The internal drive has died or become unplugged. This is the most likely case if the computer took a sharp impact or there are unusual sounds coming from the hard drive's location.

  • Mac mini will not recognize boot key sequences from new Apple keyboard

    Just in case anyone else is in the same boat as me - be forewarned. My mini died on me all of a sudden last week. My initial thought was that it was a hard drive failure. It wouldn't boot up at all. I was just stuck at the grey apple, cranking gear screen.
    I tried the usual stuff at first. Tried to boot from CD. Booting from an external FireWire drive. Nothing worked. Reset SMC, etc. Nothing worked.
    So I brought in the machine to my local Apple store and talked to the Genius. He said I had a bad logic board, and that replacing it would cost almost as much as the computer. I contemplated the idea, but couldn't afford to pay for this.
    So, instead, I just went without my mini for a couple of days - opting to use my Macbook instead. Then I decided that maybe it was the keyboard that was the issue. And yes, indeed, that was the problem. Using any other keyboard (even non-Apple keyboards) allowed me to boot from external devices, which then allowed me to identify that the issue was, in fact, a bad hard drive.
    Long story short. 1) This issue needs to be remedied by Apple in some way, shape, or form. There must be others with a potential dying hard drive in the waiting with new aluminum keyboards. 2) The Genius should have known about this issue as well.

    Any workarounds apart from the obvious? (I'd hate to stop using my otherwise awesome keyboard).
    The new aluminium keyboard is not fully compatible with the Mac mini. It works perfectly well in general use, except that it cannot be used with modifier keys at startup for such things as booting into safe mode, to access the boot loader screen or to boot to the optical drive.
    While this is a bizarre issue which it is hard to understand has not been resolved, it has been a long standing issue and well reported here. The workaround is the obvious one, to use almost any other USB-connected keyboard if the system needs to be booted with a modifier key. There's no need to stop using your aluminium keyboard if you like it - just not for situations where you need to modify the boot process.

  • PowerPC Mac Mini gets stuck at grey apple logo screen, wont start

    I have a bit of a problem and would appreciate some help, im not especially good at this stuff.
    My Powerpc Mac Mini froze up recently, having left it on for a few days without shutting down/resetting. I impatiently turned it off with the power button at the back. When I turned it on again, it only got as far as the grey apple logo screen, it now refuses to go past this screen despite numerous power resets, and unplugging at the power.
    I have reset the PMU and the PRAM as suggested by the troubleshooting, to no avail - the PRAM did work as it changed the resolution of the apple logo, but still got stuck at the grey startup screen. Its out of warranty so I have to pay for technical support. Can anyone help?

    If you have the original install disk that came with your mini, the first thing to do is to insert that, and then boot the system holding the C key down. This should force it to boot from the install disk rather than the internal drive. The reason you want to do this is two-fold: firstly that if it boots OK that way, it shows the basic hardware is OK, and secondly, it's possible that the hard drive has developed errors (likely directory damage) and the tool to check for that and attempt to resolve it is on the install disk.
    Once you've got the system booted to the install disk, exit the installer and run the Disk Utility application. That should display the internal drive (and the install disk) on the left. Select the internal drive and then click 'Repair Disk'. If no errors are found, the drive is fine and the problem lies elsewhere. If errors are reported and the disk is fixed, then you should be able to reboot normally afterwards. If errors are found and Disk Utility reports 'error on exit' not having fixed them, then run it again just to be sure, but otherwise it means the drive is damaged sufficiently that Disk Utility can't fix it. A third-party application such as Alsoft's DiskWarrior will then be needed if you want to try and fix the drive and recover data, or you can simply elect to do an erase and install, meaning the drive will be reformatted and a new copy of MacOS installed. Do not do this if you have data you need to get off the drive!!

  • Mac mini gets stuck in the start-up screen! What do I do? Won't boot up.

    Well, I talked my friend into getting a Mac mini, and now it freezes up as the OSX boots up. There appears to be a disc of some sort in the drive, so I can't even put the start-up disc in. What can I do?

    Hold the mouse button down as the machine boots, that should kick the disk out of the CDROm. The next step is to just try to reboot again if the system does not boot after kicking out the CD. If you put the OS disc in and hold down the "c " key that should allow you to boot from the OS disc, then search for the utilities folder and repair the disk.

  • Mac Mini (PPC) won't boot off install DVD

    I'm having a major issue with my 1.24GHZ G4 Mac Mini. What I want to do is reformat the HD and reinstall OSX. But for some bizarre reason the machine refuses to boot off any OSX install DVD I throw at. I've tried Jaguar and Panther as well. If I hold down the C key during reboot and wait for the Apple logo to come up, I get that but it goes no farther. I can hear the drive being accessed (and I know it's not fault because it works fine under OSX) and yet I end up getting stuck at that logo screen. I can reboot the system normally into OSX Tiger.
    I also strangely cannot partition the hard drive from within Disk Utility.
    Can anyone give advice?

    Possible options/questions...
    a) Have you tried using the original Install DVD that came with it?
    b) Have you tried booting into Single user mode and checked the drive? (Hold down Apple-S until it boots into text mode and when you finally get the prompt type 'fsck -fy' without the quotes).
    c) Also, you may wish to try resetting the PRAM immediately before booting from CD. Let it reset THREE times (hold down Apple-Option-P-R or WinKey-Alt-P-R until it has chimed 4 times) and then hold down the C key to boot from your Install DVD.

  • Mac Mini (2011) can't boot, no screen display.

    Hi, my mac mini (2011) finally won't startup today.
    It was since two weeks ago, the mini goes freeze very frequently, I discovered that the fan speed was always below 2000rpm, meantime, the CPU temp was around 80-90 degree, it is around 25 degree in the room, last Friday I installed a software named smcfancontrol, which can manually speed up the fan, and it seems better, and the computer runs faster, I think the CPU is running in full speed.
    Today, I opened a video to watch, after about ten minutes, the computer goes freeze again, and of course I force powered it down by pressing the power button on the back, then the tragic came:
    - when I try to boot up the machine, the front light turns on, then off with a "ka" sounds like the hard drive shutting down(force powering it down)
    - after around two seconds, the light goes on again, and the fan smoothly goes to full speed, there is nothing shows up on screen, as well as no apple boot up sound.
    - I tried to reset smc (power down, unplug power cable, wait 15 seconds, plug in power cable, wait 5 seconds, power on), no luck.
    - I tried to reset pmu (at least internet says it's pmu, it seems apple website did not mention how to reset pmu on mac mini, power down, hold power button for five seconds, power on), no luck
    - I also tried to unplug the memory, try with every single one to boot, no luck
    - last Friday, when I can still boot up the computer, I thought there might too much dust, I removed the fan and cleaned it up, it looks a small piece of plastic on the fan plug were damaged, but the smcfancontrol app still can control its speed, therefore I think the fan is OK.
    - during many retry, there was one time, the fan goes full speed at startup, with no front light off,(my current status is fan goes to full speed gently).
    - the computer is connected with an AV amplifier, then output to a plasma TV, when the computer is powered off, the TV displays a background of amp, when I startup the computer, although no video output from computer, the TV goes to a "No Signal" status, I dont's think this is related to my problem.
    the computer is out of warrentee, but bought only for less than two years... I really want it back to work, can someone help me? many thanks!
    wish you all have a good day.

    Hard to troubleshoot when you can't turn on the computer on any more.  One option is to bring it to an Apple store to have them look at it.  They will tell you what is wrong and how much it will cost to fix.  I have never heard of them charging for a diagnostic and an estimate.
    If your CPU was running hot all the time and your fan had small plastic pieaces, in my opinion, something got fried.  The mini is so compact, that the excessive heat may have also over heated your hard drive causing thd "ka" sound.
    If you decide to continue in to use a Mac Mini as a media server, may I would suggest using iStat to monitor it.  I use iStat on my 2011 Mac Mini Media Server to monitor CPU usage, all sensors, and internet incoming and outcoming.

  • My Mac pro 2008, not running after the Apple logo, i rebooting and i rebooting

    My Mac Pro 2008 no boot afther the Logo Apple, reboot, reboot and reboot only, and in XP, the graphic is pertubed with bad graphics ... the mémory it's good, and i thinks my card graphic is out.

    Not saying this IS your problem, but … I just went through avery similar problem with Mac Pro3,1. Here is my story.
    On boot of any Mac OP system drive, internal or externalHDD, (Lion or Snow Leopard), original Mac Pro install CD, Snow Leopard CD,nothing.  (Would only go to gray screen,apple logo, spinning gear that would stop spinning after about a minute.)  But, it would boot on XP drive.  However, in XP, on Windows black startupscreen, had alternating columns of two different patters of blue dots and XPgraphics were not as they should be (larger icons on desk top, slow response,different size of desk top (maybe 600x400 when it should have been1024x768).  Supplied hardware test showedno failures.  Took it to shop.  Their better diagnostics showed nofailures.  All peripherals (my drives, myCDs, etc, disconnected.  (NOTE: they didnot try a new video card since they did not have one.)  Still would not start even using their drives(external or internal).  Shop tried a newlogic board.  That did not work and theyput the original one back in.  Shop saidall they could come up with was new processors. This was not a cost effective option and they had none to try.
    After thinking about it more, I figured it could be thevideo card: the original 8800 GT that came with the Mac: that it was so bad itwould not start in Mac OS but would limp along in XP.  I was all set to buy another vid card one-bay just to try.  While doing thatresearch, came across several articles on the Internet that discussed vid cardfailure due to micro-cracks in some solder joints.  These develop due to age/heat cycles.  The proposed fix was to ‘reflow’ the solder.  Figured it was worth a try before spendingthe money on a new vid card.  Found thesedetailed instructions on youtube.  http://www.youtube.com/watch?v=T7um_hZYom4  I followed the procedure, put the vid cardback in, and now it works just fine.
    I did not and would not do this until I had ruled outeverything else.  But, it has worked forothers and it did work for me.
