Brand new Mac Mini will not boot after 10.6.6 Update

Problem is exactly as described here: http://forums.macresource.com/read.php?1,1069909,1070656
The 1st restart was fine then it restarted for the 2nd time & it got to the gray screen with Apple logo & spinner. It sat there much longer than it ever had before then the Apple changed to a circle with a slash.
I tried booting into single user mode and it is hanging "waiting for root device"

Sounds like maybe your disk died.
I suggest that you boot from the install DVD that came with your Mac and run AHT to check it out.

  • HELP Mac Mini will not boot after 10.5.1 update

    After I tried installing 10.5.1 I received a warning message that the update will not be installed because of an error and I should contact the vendor. After that the Mini tries to reboot. It keeps repeating the process over and over. I have tried to do safe boot mode by manually turning off the computer and then restarting while holding shift, but nothing happens. Can anybody help?

    I think the problem might be with the external HDD I am running with this machine. I am reinstalling everything now from my time machine backup. I just added this hard drive the other night and it is loud as all **** and I believe it is why my machine has crashed. Before I added the drive, my system was running pretty good. It is a Calvary 160gb drive. I think I am going to have to send this POS back to newegg and get myself another Lacie drive, because my other Lacie is running smoothly.
    I'd go with the LaCie. I got two from Amazon, 320 and 500 and both are quiet, have 800MHz FW and I have had no problems with either of them. The new one also has a 3-position switch - Off/Auto/On which allows it to sleep when not being accessed when in Auto.
    I suspect that your external HD was the problem all along.

  • Mac Mini will not boot after Security Update 2008-007

    Hello,
    A G4 Mac Mini machine I was asked to take a look at will not boot after the owner (succesfully) installed Security Update 2008-007 from Software Update. Booting always hangs at the blue screen after the Apple logo, and booting in verbose mode reveals that WindowServer is crashing repeatedly. Permissions and filesystems have been repaired, PRAM reset, etc. Safe boot also exhibits the same problem, but it is possible to boot to single user mode. Hardware checks out fine with diagnostic utilities.
    Any suggestions on how to fix this? Unfortunately, backups are not available (it's not my machine =).

    Hi Arkku , and a warm welcome to the forums!
    I'd certainly give Sig's advice a try first.

    "OK, restart your computer, hold down Command-s and type in the following:
    /sbin/fsck -fy Enter
    /sbin/mount -uaw Enter
    rm /var/db/.applesetupdone Enter
    # The rm command is the remove command which deletes the file.
    # Robert: I'd rename the file via: mv /var/db/.applesetupdone /var/db/.applesetupdone.old
    reboot Enter
    Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

  • Mac Mini will not boot after getting SBOD

    Hi,
    I was having problems with my Mac Mini being really slow to respond last night. I kept getting the SBOD every time I tried to move between applications or even between sites in Safari. It took an age to log on, sitting on the 'checking password' screen for minutes at a time every time I woke if from sleep/screensaver.
    In the end I shut everything down this morning and tried a restart - however I ended up having to leave it before it had started up and go to work. Returning tonight it was still stuck on the grey screen with the wheel.
    I tried both a couple of suggestions I found on a 'freezing after upgrading to 10.6..' thread - one was to reset the SMC, the other was to rest the PVRAM (or something like that - it involved holding down command-option-P-R) at start up. Both were unsuccessful - it's still sat here with the grey screen & the spinning wheel.
    Any suggestions on what to do next? I've assumed that I'm on the latest version of Snow Leopard as I always tend to install the latest updates - but I can't be sure ... and obviously I have no way of checking!
    HELP!

    I tried the Disk Utility, which was unable to repair the problems. It then got worse, after not finding anyway to shut down (the only options I had were restart or start up disk) I just switched it off. Completely forgetting that this wouldn't eject the DVD! I then tried starting up again with the install DVD in an effort to try and find a way to eject the DVD, but now it just gives me a grey screen, no Apple logo, no gear wheel.
    I now have an appointment with the Genius Bar today.

  • Hello, mac mini will not boot. I get a file symbol with a question mark, then a white screen, Hello, mac mini will not boot. I get a file symbol with a question mark, then a white screen

    Hello, My mac mini will not boot. When I turn it on, I get the chime, then the white screen, then the apple symbol, then a file symbol with a question mark, then the white screen and then it stays like that.
    Is this a bad hard drive?

    Sounds like it.  Try booting from your OSX restore DVDs - startup and hold down "C".  This will take AGES! Then run Disk Utility from the menu. 
    The flashing ? means your system is corrupt, dead, not there, on a dying HD, etc...

  • Mac Mini will not boot OS, can I get to files with another Mac?

    My mac mini will not boot the OS proserly, it goes to a screen that tells me that some root folder can not be found.
    The install CD works and I can boot to it. The disk utility reports no problems, all disk repairs done and OK.
    The computer still will not boot to the OS.
    How can I get the files I need off the drive before I reinstall the OS?
    I have other Macs and fire wire cables, cross over cables, regular eithernet cables. What can I do?
    Thanks!

    How can I get the files I need off the drive before I reinstall the OS?
    Connect it to another Mac with a FireWire cable and start it up with the T key held down.

  • My mac mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone

    My Mac Mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone. I had switched the start-up disk back to the original of course. Now all I see is the Apple logo. What should I do? Thanks in advance.

    Try disconnecting any external devices, especially hard drives
    and try rebooting.
    If that doesn't help, then :
    If you are running Lion, boot to the Recovery HD and run a
    Repair Disk on the OSX partition.
    If Snow Leopard, boot to the installl DVD and run Repair Disk.
    Also, you may want to bookmark this:

  • Help - Mac Mini does not boot after re-install of OS X

    Hi,
    I have a Mac Book Pro and Mac Mini. I needed to reinstall my Mac Mini but lost the install disks. The install disks of the Macbook do not work (machine specific). So what I did was boot the Mac Mini in firewire target mode and installed OS X to it from the Macbook. Worked ok. Except for one thing: The Mac mini does not boot the fresh OS X installation. I get a blinking folder icon with a question mark on top of it.
    I booted from the Mac OS X install disk, repaired disk permissions etc. and tried to use the "Startup Disk" utility to select the hard drive as a boot device. But that utility does not offer me to select the hard disk, it doesn't even show up (while DiskUtility can perfectly see it).
    Any hints for me? I am pretty much stuck right now.
    Thanks

    Well, see, the fact that it wouldn't let you boot from the MacBook install disks should have been your first clue to not try to do it. There's a reason it wouldn't let you. The MacBook install disks contain a version of the OS specific to the MacBook, in order to prevent people doing what you just tried to do (ie, installing the same copy of the OS on multiple machines).
    If you don't have the Mac Mini system disks any more, you'll have to go buy a copy of OS X. You could also ask for help from an Apple Store, if there's one in your area, but I honestly don't know if they would give you new disks. I would think they should (for a small fee), since Mac Mini system disks would be useless to anyone who didn't already own a Mac Mini, but you never know.

  • Mac-mini will not boot up.

    After downloading the latest OSX version for my mac-mini model A1283, it attempted to automatically re-start and stopped with a graphic on the screen and no control of the cursor. It will not boot up. No screen at all. Keyboard SHIFT key light does not go on. The power button will start and stop, but no tones or screen. Has worked fine for 2 years after upgrading hard drive running both OSX and Windows 8. Is this a memory or logic board problem?

  • 2013 new Mac Pro will not boot up from and external hard drive

    New 2013 MAC PRO running Yosemite will not not see a bootable external hard drive when starting up using option key?  Same External hard drive will boot up on 2013 Mac Book Pro running Yosemite.

    Reading between tea leaves sometimes leaves some things to imagination.
    You used SuperDuper latest version that was recently upgraded for Yosemite on a laptop running 10.10 (or even 10.9.3+) that is in a X-brand USB3 drive enclosure, not bus powered btw, moved it to the nMP and plugged it into a direct port, not going through a hub (monitors have hubs of course and there is only one real bus+controller on the nMP that ALL USB3 travels through.
    Thunderbolt and self-powered would be nice but they cost a bit more.
    I have read where Carbon Copy Cloner (now v 4.x) worked where others failed. I use to use both but have used CCC since its inception and use back in 10.2.2 forward along with SD! for a few years based on comments here.
    Drivers missing? someone compared system extensions and found the ones needed for say the nMP are not there? how about running a 10.10.1 combo update and see if that changes - we USE to be able to apply updates to a system that we were not booted from, very handy (could update a sparse disk image of a system that way, one created with CCC).
    WD Passports seem popular with laptop users, but they come here to this forum complaining that it doesn't work, disappears off the bus (spins down goes to sleep, acts like a green drive acts).

  • Mac mini will not boot up with two monitors attached

    New Mac mini running OS 10.10.1. I have a LCD monitor attached to the HDMI port, and a Cintiq 21 UX LCD monitor attached to a thunderbolt port.
    It boots up properly with only the first LCD monitor attached to the HDMI port.
    When I leave both monitors connected before starting the computer I get no chime, and a black screen. The light on the front of the Mac mini comes on, but nothing else happens. I have to turn off the Mac mini, unplug the second monitor and then reboot. It always starts up perfectly then. After starting the computer, I plug the second monitor in, and everything is fine.
    It’s kind of a pain in the neck to constantly plug and unplug the second monitor from the back of the Mac mini. Is there anything I’m overlooking?

    Thank you, Illaass! Resetting the SMC solved the problem! I tried that first because I would prefer not to lose any preferences, and also because it was the easiest to try. You must be a genius in addition to being such a good egg!
    (This is the number of smiles I smiled after my Mac mini booted properly with both monitors connected.)

  • Mac Mini will not boot up at all

    Mac Mini 1.5Ghz Intel Solo, will not boot up now. It first froze when playing a song in iTunes. I shut down "the hard way." Now it can't make it past the gray boot screen. It's not even responding to any keyboard commands on boot. I can't get into Safe Mode, Boot from Recovery Disc or Single user.
    HELP!!!!

    If you have the original Apple Aluminum usb keyboard, the startup modifier keys won't work with your Mini. But just about any other wired usb keyboard should work.
    If you use a PC usb keyboard, Alt maps to Option and the Win key maps to the CMD (Apple) key.
    If you just want to boot from the install or recovery disk, then the Apple remote can be used: holding down the remote's Menu button at startup works the same as holding down the Option Key, namely, it gives you the choice of what disk/disc to boot from.

  • New Mac Mini will not recognize bluetooth keyboard

    I just bought a new mac mini, and the apple keyboard.  I can see the welcome "Use english" screen, and I press ENTER on the keyboard but nothing happens!  I know the keyboard is not the problem becuase I tested it on my iPad and it worked.  I've un-paired it with my iPad and tried again and nothing happens.  The trackpad pointer is visible but it does not recognize a CLICK.....WHAT CAN I DO ????   (I don't have a wired keyboard or mouse to hook-up to it )

    yeah, it works on my ipad with no problem.  I've re-booted too.  I'm thinking the only way is with a hard wired keyboard to get it booted.

  • Mac Mini Won't Boot after 2008 008 Security Update

    I have 2 mac mini's both identical systems - ran the security update at home - rebooted and noticed the movements of the mouse and the mail application was 1/2 to a second slow/behind - decided to restart - it took 3 restarts and it finally came back and then locked up
    I ran Disk Warrior and version 4.0.1 could not fix the problem - version 3.0.3 said it could and replaced the directory - but upon restart it would not boot - I became mesmerized by the spinning dial
    I will not run the update at work and had to substitute my titanium at home in the meantime
