My Mac mini turns on but doesn't move past the grey screen..... HELP??

Hi,
I have had my mac mini for 3 months and i went to turn it on today and it wont move past the grey screen with the apple logo and the swirling icon underneath.  It had started to drop internet signal and also reacting slow and now this has happened. I have only had it three months from new and i dont know what to do. I have done a safe reboot etc and nothing has worked !! HELP!!

Intermittent problems are by far the most difficult to identify and correct. You can run a test one time and it passes with flying colors and the next time it fails. Apple Hardware Test and Disk Utility are definitely the not the most rigerous tests available and are not nearly as thorough as the tests available to the Genius Desk personel.

  • My computer suddenly decides not to work and turns on but does not go past the grey apple screen with the loading wheel.. it will not go to my desktop. What should i do?

    can somebody please help me fix this issue, i have been sitting at my computer all last night and this morning trying to figure it out.

    Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
    Or if you are running 10.7 Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 partition.
    When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
    If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
    If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

  • Mac Mini turns on, progress bar loads slowly on the apple screen, then it just turns off. What's happening?

    So the power went out and my mac mini came on when the power came back on and as it was loading the power went off again. It didn't come on for a while but when it did the mac mini would load much slower than usual on the apple screen then the progress bar would get stuck at less than 50% before the mac mini would just switch off. It doesn't restart or anything, it just turns off. Go to turn it back on again, same happens, turns off. Try to boot it up in safe-mode, loads slowly then just turns off.
    Please help!

    You can boot the problem Mac to Recovery like you did before. Attached the external HD and then install Yosemite to the external HD. That will erase the external HD and the external HD will have to be formatted in Mac format.
    The Recovery link in my previous reply covered that.
    If necessary, once installed on the external HD, boot while holding the Option  key. Choose to boot from the external HD. Once booted up use Finder to copy importent files the external HD.
    I would also backup those importent file to another device/media too.
    Then replace the failed HD.
    Then you can clone the external HD to the new HD

    Note that the Free SuperDuper does not clone the recovery partition to the new drive but the paid Carbon Copy Cloner does.

  • PowerBook G4 1.67GHz Won't Boot, Doesn't Get Past the Grey Screen

    The other day I was attempting to Safe Boot, and during the grey screen with the rotating cog, I could hear the hard drive spin down, the the display would turn off. The computer worked fine for the next few days, and now when I attempt to boot it (with nothing in the disc drive as well), it does the same thing. It simply shuts down before getting to the "Log In" screen.
    When I used the Tiger install disc (note that it was a Tiger disc that came with our iMac Core 2 Duo, my other disc is at my parents' house), and held the C key while booting, I experienced my first kernel panic. I restarted and ejected the disc, but the computer still won't boot. I tried resetting the PRAM by restarting and holding CommandOption+PR, and I've even let it cycle a few times with no luck. I also did what was suggested on an Apple support page, where I remove the AC adapter plug, remove the battery, hold the Power button for 5 seconds, re-insert the battery, reattach the AC adapter, and try starting that way, and that didn't work either.
    I have no idea what the problem is, I've never had an issue with the computer before at all. Any suggestions?
    (I tried posting this in the Tiger forums, but it was suggested that I post here instead)

    Ah, I believe I do have the a TechTool CD that came with my old iBook, perhaps I'll give that a shot.
    I first noticed the issue when trying to Safe Boot because I was attempting to install the Flash 9 player. Apparently many people are having issues with it, and it was suggested to me on the Adobe forums that I try installing it in Safe Mode (the install software hangs at "Items Remaining to be Installed: 4").
    I'll bring my PowerBook to my parents' house this weekend and see if I can give it a shot with the correct disc. I'll try to post back here to let you know if it worked out!

  • MacBook Pro will turn on, but won't go past the gray screen.

    Earlier today, my MacBook Pro took a small tumble to the ground.  I did not shut off, but it was working a bit slower. I decided to do a restart on it and now it will turn on, I can hear the CD drive is still operational, but it gets to the gray screen with the Apple logo and the spinner at the bottom and sits there.  Any suggestions or thoughts?

    Use Target Disk Mode:

    You will need a Firewire cable.
    Another option is to extract the HDD from the MBP, place in an enclosure and then connect it to the iMac.

    help with my iphone 4 ive tried everything i know

    Reset, hold both the home and power buttons until the iPhone restarts again, usually takes about 10 seconds of holding both buttons. If still problem, you may need to Restore the Firmware of your iPhone. If you decide to do this, try DFU Mode Restore. Steps for DFU Mode are, open iTunes on computer, connect iPhone to computer with USB Cable. Hold both Home and Power Buttons for exactly 10 seconds, release the Power button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds of holding Home button. If the iPhone screen is black, blank this is DFU Mode. Click the Restore button of iTunes. If Restoring iPhone Firmware fails, and you have Warranty or AppleCare make Genius reservation and take iPhone to Apple for resolution.

    I have Snow leopard on my computer, and I tried to do a hard restart as an article suggested, but it did not work. I also tried cleaning out the PRAM.
    The only things I did last night:
    -cleaned the history of Firefox out, including cookies
    -let it unplugged all night
    -plugged it back in the morning, it took a long time to figure itself out, but eventually the time was correct and I got on the internet for a bit
    -shutdown the computer since I was going out and thought it would help the computer charge
    -came back, tried to turn it on, and found that it would not go past the grey screen the apple on it and the spinning wheel even though I left it for 20 minutes or more
    -tried turning it off and on to no avail

    Before doing a reinstall, which may not be needed at this point,
    Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
    You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
    Then Repair Permissions.
    No need to report any Permissions errors........we all get them.

    when i turn on my computer it stays on the grey screen and then turns off by itself. How can I fix that?

    Hi , and a warm welcome to the forums!
    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 & clear caches.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
    If 10.7.0 or later...
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
    Hold alt or option key at bootup, do asny boot choices show up?

  • My Mac Book will not go past the grey screen

  • My G5 (non intel) starts up but does not go past the grey apple screen

    My G5 (the non intel kids machine) starts up but does not go past the grey apple screen. It chimes, the grey apple screen comes up 20 seconds later with the rotating thing-ie, then the fan kicks on 1 minute 35 seconds later. It stays on that screen indefinitely.
    I tried restarting without any cables connected to it with the same outcome. I tried to insert the OS X disc and pressing the "C" key and cannot get past the password page. I also tried to start it pressing the OptionCommand+PR keys with no results.

    I am experiencing this problem as well. I had assumed it was a result of attempting to uninstall the Boot Camp drivers because I was getting a blue screen error every time I tried to startup with Windows. But I had also installed some updates for OS X at the same time so it could have been caused by that as well. I've erased everything now and I am trying to reinstall OS X but I'm three attempts in now because the installation has just been getting stuck in an indefinite loop at random points during the installation.

  • Computer Turns on But doesn't get past Apple Logo and Spinning Dial

    Hi everyone!
    I totally stuck!
    When I turn on my MacBook the normal chime sounds, the apple logo pops up, and the dial that constantly spins appears. But it never gets past that initial screen. I've tried letting it sit off for a few hours, taking out the battery, and trying to turn it on with the Power Adapter plugged in. I love my Mac and I'm very surprised by this.
    If anyone knows how to fix this I would greatly appreciate it!

    Welcome To  Discussions HSHS07!
    To begin, run Repair Disk, and post the results.
    THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
    1.Insert the System Install disk, Mac OS X CD-ROM disk, or Restore DVD disk, then restart the computer while holding the C key. Use the System disk, of the OS, that is currently installed.
    2.Once started up from CD or DVD, on the Menubar at the top of the screen, choose Utilities from the Installer contextual menu.
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc to access Disk Utility.

    4.Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5.Select your Mac OS X volume, if necessary.
    6.Click Repair. If DU reports errors it has fixed, re-run Repair Disk until no errors are reported.
    7.Repeat steps 5 & 6, but select the Hard Drive this time. It's usually the first listed with the manufacturer's model number. Make note of the S.M.A.R.T. status.
    8.When finished, select Quit Disk Utility from the Installer menu.
    9.Select Quit Installer from the Installer menu.
    10.In the resulting pop-up window, choose restart.
    11.After the computer has restarted, you can eject the CD.
