My mac book 1,1 Won't boot

Hi I tryed to boot my mac book and it won't boot, it goes on a white screen for about to min then a folder with a ? comes up! PLEASE HELP ME

Hi...
Try here >  A flashing question mark appears when you start your Mac
First thing I would try is booting while holding down the Option key. If the drive is ok, you should see the Startup Manager window where you can select the startup disk and restart.
Unfortunately, 90% of the time, the ? on boot means the drive is failing or has failed

    My mac book pro will not fully boot up. I have the grey background with the apple sign and the timer going round...but 20 minutes later still no desktop

    You could try doing a hard shut down (holding the power button or yanking the battery) and then doing a safe boot by holding the shift key at startup:

    Also, not sure if this applies in your case, but I've had that happen when there's a USB drive inserted either in the computer or a connected external keyboard.  I did a hard shut down, removed the drive and it went through a normal start up.

  • Hello, I have a early 2008 Mac Pro and it won't boot even with SL DVD

    My Mac Pro (3.0GHz quad core (dual CPUs) 8GB 667 RAM) won't boot. it gets to the grey screen/ Apple logo and hangs on the logo for a few seconds then flashes either the question mark folder icon or on the circle-slash icon () for about half a second then the logo for a few seconds and repeats. It will go into Target Disk Mode (T) but not Diagnostic Mode (D)
    Here's what I have done to try to fix it:
    unplugged all peripherals
    tried to force DVD boot holding C (checked disc for errors on SL iMac)
    removed all HDDs and rebooted holding C, plus a combination of having some in/ some out.
    removed first DVD-ROM and used second drive
    removed second DVD-ROM and used first drive
    held shift during startup
    held option during startup
    removed graphics card
    put HDDs back in with GFX card out, plus combinations
    put only the boot drive HDD in (not time machine or 3rd HDD)
    put blank HDD in and booted DVD
    put mac formatted (used iMac to format) HDD in and booted with DVD
    used an G4 USB keyboard again for all of the above
    All of this has not worked so I am stuck with what to do. It was all working fine a couple of days ago. At the time it randomly shut down I was trying to use Boot Camp to create a Windows 7 area, but I made sure it was using the 3rd HDD I had put in the machine a couple of days before so it shouldn't be interfering with normal operations. I had also formatted it to NTFS earlier but reformatted it on the Mac Pro to Mac OS Extended - I don't know if this is even relevant.
    Any suggestions (except taking it to a Apple repair centre as I can usually fix anything myself!)
    Thanks.

    Go to System Profile and look, does it say "MacPro3,1"?
    That is 2008.
    FBDIMM would be 800MHz. Did you use older slower 667MHz in yours?
    You can but take a hit in performance.
    Sounds like MacPro1,1.
    Mac Pro (3.0GHz quad core (dual CPUs) 8GB 667 RAM)
    In 2007 March an 8-core 3GHz did come out 2,1.
    So just to be clear.
    ===========
    It was all working fine a couple of days ago. At the time it randomly shut down I was trying to use Boot Camp to create a Windows 7 area,
    Whenever you want to install Windows, remove all the drives other than the one Windows goes to. And if you use a dedicated drive YOU DO NOT NEED Boot Camp Assist, unless you use XP, which really is limited and crippled (one processor, 1.9GB RAM support).
    And when it freezes, your only choice is to nuke (reformat) and restore or get out that backup CLONE you made before (ie, Step #1 in the Boot Camp Guide).
    Sure that whole NTFS / MBR / GUID could be an issue, but you should just have a blank drive or clone.
    No don't bother Apple, they seem to not have a good sense about Windows on Mac Pro anyway.
    Other than zap pram from cold boot / tried booting with NO drives inside and just 10.6. DVD - should be fine.
    You should be fine iwth Windows 7 DVD and one drive, or even XP.
    Make sure you take your time and reconnect cards etc properly and any cables.
    Booting from OS X DVDs may not work if there is a drive with a totally shot directory or partition table. Put them in FW case and turn on AFTER OS X is booted.

  • Mac Book Pro (2012) tion not booting after installing boot camp

    On Sunday I installed windows 8.1 on a partition that I made using boot camp assistant. It worked fine after I installed windows yestarday. Today when I turned on Mac Book Pro and booted it up from the OSX Mavricks partition it turns on but after I hear the start tone, I see the apple logo, a progress bar and then a couple seconds later I see the spining gears and  then my computer shuts off. I tried booting the computer up from the windows partition and that worker fine. I tried booting it up from the mac OSX parttion and same thing again. I tried pressing Comand R on start up to go to disk utility so I could verify the Machintosh HD disk. It said that it needed to be repaired but when I went to  go  repair it I get an error message saying " Disk Utility Cannot repair this disk... back up your files." Next I try going in to single user mode and I type /fsck -y this does not work either. I tried booting into safe mode but that did not work. What should I do next?

    Hello Jack Ryen,
    Thanks for using Apple Support Communities.
    From your post I see that your Mac will not start up in OS X, and the result of you verifying the disk indicates you need to back up your files and reformat.  As Disk Utility states, the next step for this issue is to backup and if possible reformat the drive.
    Important: If Disk Utility is unable to repair the internal drive, you should back up your important data immediately and if possible, reformat the drive. Consider bringing the Mac to a Genius at an Apple Store or an Apple Authorized Service Provider for further diagnosis. Be sure to ask that, if the drive needs reformatting or replacing, they contact you about escalating your case to a special data recovery service. If you plan to visit an Apple Retail store, you can make a reservation (available in some countries only).

  • Mac Pro 12-core won't boot Mac OS X 10.6 "Server" Install DVD

    I have just received my new Mac Pro 12-core today.
    I tried to boot from my Mac OS X Server (10.6) Install DVD with no success.
    I WAS able to "upgrade" from the preinstalled Mac OS X 10.6.4, but I need a clean installation.
    I first thought there was a problem with the internal DVD drive, but I could boot the provided Mac OS X Install DVD. I also tried to boot the "Server" DVD from a firewire external DVD drive, with no success. I even tried "target" mode, using the DVD drive from a Mac Book Pro, with no success.
    The server install DVD is not corrupted, as I used it recently on my 2007 Mac Pro 8-core.
    Please help.

    My Mac Mini late 2012 model with 500 GB and 4 GB won't boot up because I by mistake dropped it in the floor. I'm using OS X Yosemite. I've dropped it in the floor countless of times before but this time it just wont work. When I try to boot it up a picture of a folder with a question mark starts flashing in the middle of the screen, like this:
    But mirror flipped.
    I'm wondering if there is a way for me to fix this problem.

  • MAC PRO HARD DRIVE won't boot

    HARD DRIVE won't boot past APPLE ICON, grey spinning wheel on grey screen. Tried using install discs, no go past the icon.
    Replace small battery inside? replace chips? Logic board replace as last resort.  Can't take it away from work at this point to an apple tech.
    Had just installed updates to snow leopard and was successful...but went to restart it...and this crap happened.
    Thanks for any help.

    < Edited by Host >

    I'll try that tomorrow. Thinking it could also be:
    1)  The PRAMM battery. found info on that they can wear out close to 5 years. This MAC PRO is close to that now.  And I use a lot of power on it.
    2) MAC PRO is plugged into a  SURGE PROTECTOR, instead of right into the wall outlet.
    3) Been doing a lot of FORCE QUITS and HARD BOOT -- unplugging it directly when it wouldn't shut down soon enough --  lately this past year.
    I just assumed that this MAC PRO with the XEON QUAD CORE etc., was a heavy duty enough NLE,
    that i wouldn't have these problems. It's not fully loaded with all the chips it can carry...and I don't have near enough external terabyte hard drives for storing video and audio files to edit. I've been storing wayyy too much
    on the internal hard dives and just have to stop that.
    I noticed these past few days that much of the LETTERING for hard drive icons and folders' titles
    were starting to look in OVERLAPPING of the lettering. That was my first hint that  something was up.

  • Mac Pro 3.1 won't boot

    A couple of weeks ago i turned on my mac pro and it didn't boot!
    The video card fan whirls around for about 5 seconds and clicks off.
    After looking around this forum and others for a while i thought it might be a power supply issue. So i took the tower to my local Apple repairer to get fixed. I called a week later to find out what the deal was and was told that its not the power supply and they were still looking at it. A few days later i got a message saying that it had bad ram and was fixed. leaving me 2gig of ram down (i had 8 gig of ram leaving me with 6 gig) and $75 out of pocket.
    No sweat!
    About a week later it did it again! Not booting!
    i push the power button a few times and it booted! Phew!
    It did this for a couple more weeks. Not booting sometimes. A few pushes of the power button and away we go.
    Until of course i had a recording session booked and the mac pro would not turn on at all!
    I've taken all the ram out (8 1gig sticks) and just installed 2 gig at a time. Going through all of them. Even the one the repairers said was bad. With no luck. I've reset the SMC and take the battery out and put a multi meter over it and it seems fine. (I must say that one day the screen went all weird. Kind of like blurred checkers for a minute but came good again.) I tried to boot it up without the graphics card, no luck!
    I'm not sure what i should do??
    Take it back to the repairer for another $75 or buy some more ram and see what happens.
    Is it possible that ALL the ram is stuffed?
    Is it possible to boot up without the video card?
    Any advice you guys could give me would be greatly appreciated.
    Thanks heaps
    Damien

  • Mac G3  Blue & White won,t boot anymore

    Hi everyone
    I havea a big problem and I hope someone can help me out.
    I have a G3 Blue & White with
    PCU:300 Mgz
    Rams:896 MB
    HDD:130 GB
    I had Tiger installed on it and worked perfectly,but classic would not boot up because it would say that Mac OS 9.1 was not installed.
    So I decided to copy the system folder from my OS 9.1 intall disk to my hard drive(big mistake).
    Then I went on Preferences, Startup disk, and it showed the icons of Mac OS X Tiger and Classic 9.1.So I decided to put Classic as startup disk(bigger mistake)because now,my Mac won't boot.It keeps saying
    "The system software on the startup disk only functions on the original media,not if copied on another disk.
    Now even if I try to boot with my install disk,OS 9.1 or Panther or Tiger,it just won,t boot from the disk.There is that little window with ? in it.
    Now I have a Mac that won't boot.
    Please,can anyone help me out
    Thank you
    Mario

    Mario:
    I don't mind reformating my HDD and do a clean installation but I cannot boot no matter what i do.
    This may be a problem, as you will need to be able to boot from both the OS 9 install disk and the Tiger install disk. If you are not able to boot it may be that you are having an issue with the optical drive. In any case, I will post some directions and we will see if you can manage to get it going. First we will do a complete low level format with the OS 9 installer, install and update OS 9 and then when that is working satisfactorily we will install and update Tiger. All of this, of course, is dependent on whether you can boot from the optical drive.
    Format and Install OS 9
    This process will completely erase everything on your Hard Disk Drive. Be sure to Backup your User Folder and all third party apps you can't afford to lose
    • Boot from your OS 9 install CD holding down C key.
    • Go to Drive Setup and reformat your drive as Mac OS Extended (HFS+)
    • Reinstall OS 9
    • Update to 9.2.2: Mac OS 9: Available Updates
    • Update your firmware
    Once this is completed, you are ready to install Tiger.
    Installation Process
    • With computer shut down insert install disk in optical drive.
    • Hit Power button and immediately after chime hold down the "C" key.
    • Select language
    • Open Installer and begin installation.
    • Select installation option as Archive and Install. *This is important as you do not want to overwrite OS 9, which you just installed.*
    • Choose to Customize and deselect Foreign Language Translations and Additional Printer drivers.
    Optional: Check box to install X11 (Tiger and later) BSD Subsystems (Panther & earlier).
    • Proceed with installation.
    • After installation computer will restart for setup.
    • After setup, reboot computer.
    • Go to Applications > Utilities > Disk Utility.
    • Select your HDD (manufacturer ID) in left side bar.
    • Select First Aid in main panel.
    • Click Repair Disk Permissions.
    • Connect to Internet.
    • Download and install Mac OS X 10.4.11 Combo update (PPC) (Tiger).
    • Repair Disk Permissions as previously.
    • Go to Apple Menu > Software Update.
    • Install all updates.
    Computer may restart after updates.
    • Go to Applications > Utilities > Disk Utility.
    • Select your HDD (manufacturer ID) in left side bar.
    • Select First Aid in main panel.
    • Click Repair Disk Permissions.

  • Mac Book Pro Charger won't charge

    Just yesterday my Mac Book Pro "L" 85W Magsafe Charger would not charge my laptop. Eventually I tried using my sisters Charger, a 60W "T" Magsafe charger. It seemed to charge for a day, but today that charger has died as well. I can't understand why these chargers are dieing suddenly, whats happening and what can I do?

    The Apple power adapter includes circuitry that cause the adapter to shut down for various reasons: over-temp, over-voltage, over-current.  The adapter can be reset by unplugging it from the computer, unplugging it from the wall, waiting 30 seconds, plugging the AC input adapter cord into the wall and, finally, plugging the DC output adapter cord into your computer.

  • Mac OS X Tiger won't boot, results to OS 9.

    My PowerMac G4 currently holds two startup disks, OS 9, and OS X 10.4.11
    However, after a recent update for iTunes and security, my machine got shut off manually and the next time I booted my mac is went directly to os 9. I tried restarting and holding down option to show available boot disks, and only os 9 showed up. However, now Os 9 struggles to boot with extensions on. But evennin os 9 it shows my os x disk and it is fully functionable. ( as in file browsing) can anyone tell me what is happening or what I can do?
    Message was edited by: NickG9090

    By abnormally shutting down the OS X partition has most likely gotten scrambled. You will have to reformat that volume and reinstall OS X.
    Since OS 9 is working you may still be able to copy your personal files to an external drive so they won't be lost.
