Mac Book Pro start up, Mac Book Pro start up

My Mac Book pro is taking very long ot start up sometimes getting to home but then not loading anything else. it is a late 2011 model with Mavericks and about 4 years old now. i cant enter safe boot for some reason which is very annoying but cant reset PRAM. any thoughts on how to get it to work? it wont boot up after a crash the second time this week, which is the only time iv ever crashed. the other time it just shut down due to a kernel error. any thoughts on how to fix this problem? thank you very much for your time.

  • How to start my mac book pro safe mode?

    my mac book pro is not start up but showing white screen . what should i do ?

    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 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 11. 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.

  • Hi all - troubles sons mac book pro (bought Dec 2011). When he turn it on - get folder with ?  I assume can't find start-up items. trouble is - he can't get disk to go in

    HI all
    Pardon me for the stupid title - -been some time since on the forum
    This is much better.
    So the situation on son's Mac Book Pro.
    It seems a few days ago the computer would not take a CD - -not  huge deal
    Then suddenly he had trouble.
    Turned on computer and get the folder with the ?     I am pretty certain this means it
    can't find the start-up items.
    I guess he tried to do some "diagnostics on the internet - it was a Hardware diag.
    and said everything was OK but couldn't find a HD
    So he bought a new HD and we just installed it. Start tje computer and the same question in folder.
    He bought the HD from apple so not an aftermarket.
    I guess he is not sure where is start-up disks our (kids)   but what can we do now?
    He is at our house now and can't seem to connect to the internet becuase he can't see my network
    which is wireless.
    Is there something we can try - -should we re-install the old HD - -the new one may not be formatted
    not sure all we know is it was from Apple direct.
    He just told me the OLD hard drive could be read by a device at school.  So it seems perhpas the HD MAY? be
    OK  but there is some sort of communication thing going on.
    In the old dayson my G-3 slot  - -we would start up with a network
    Not sure how do do any of that on this book
    PLease help - - very important (he is a grad student and needs the computer that is why he paid for
    on day shipping
    What do we do?  Any tips tricks?\  please offer any ideas - -dad is stuck - -Thanks
    Jim

    Hello Grant - -Thanks - -
    I notice you are west of Boston - -we in Medford and son goes to Tufts in town
    (small world)
    Not really certain what you are telling us  - - I am not good at computers
    A couple of other things that may be tips - -
    1 - on wednesday of this week
    our son noticed the fan was going on almost continuosly,
    After that trouble started - -
    2. - When we put the new HD in - -same things happened,
    which is ? mark in folder (start-up items)
    3. - His computer will not see my wireless even if I put it next to my I-mac
    It sees several networks but not mine - -and if we type in my netwokr
    info - -it will not take.   He wanted to try a network start-up .
    I forget how that is done.
    4, - The bottom of the computer is getting hot - -much hotter than i think it should.
    any ideas why his computer won't see my router?
    I think he may just have to take it to Apple Store on Newbury Street.
    Would they be able to get his info off the old HD assuming it is still good and
    transfer to the new HD fairly easy.
    LAstly - - I am pretty certain I have the str-up disks for my I-mac which is running
    10.5.8.
    Would I be able to do anything with my computer and hook into his computer
    into mine like an external device or something like that
    I really appreciate your thoughts and efforts on this  and must admit I have no
    external enclosrure?  but I have an external HD on my I-mac
    As you can tell - -I am not to good at this
    Thanks from Meffa    (lol0   Jim the father

  • HT4061 iTunes will not open when my iPhone 4S is attached to my Mac Book Pro. iTunes will start up but as soon as my iPhone appears in the list of devices the program then quits and displays the message 'iTune Quit Unexpectedly'? Can anybody help?

    The Problem/s
    1. I am unable to sync my iPhone 4S with my Mac Book Pro, either by cable, wifi or bluetooth
    2. iTunes will initiall open and briefly identifies the iPhone in the Device section in iTunes.
    3. When iTunes starts to read the iPhone (displaying the spinning wheel), it immediately then quits and
    4. Opens a 'dialogue box' which displays the message "iTunes Quit Unexpectedly"
    5 The dialoge box offers the following button options to:-
    'Show Details'
    The 'Show Details' button will open and display a list of the 'Problem Details and System Configeration'. To the average user the information is useless, as one doesn't know what to look for to solve the problem. This is a long and detailed report (too long to include in this message), which includes information such as:-
    Crashed Thread:  20
    Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
    Exception Codes: KERN_INVALID_ADDRESS at 0x00000000000006f0
    'OK'
    The 'Ok' button simply quits and closes the dialogue box
    'Reopen'
    The 'Reopen' button will again reopen iTunes, briefly showing that it is trying to read the iPhone in the Devices section, but then returns again to display the same dialogue box.
    Other Information
    1. iTunes will still start normally once the USB cable is removed from the Mac book Pro, but crashes again once the USB cable is reattached to the computer
    Any advice or help offered would be greatly appreciated.
    Sincerely
    Rob

    My Mac Book Pro changes the saved home page each time I open Safari.  I am also getting random tabs opening with various "cleaning up" my computer junk.
    How do I get rid of this?  I tried some of the fixes listed but they don't seem to work or I am doing something wrong.

    You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
    Back up all data before making any changes.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
    Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

  • My mac book pro does not start but has error message with a question mark on screen. took it in and was told probably the hard drive as could not reconize it so bought new one but still not connecting.what do i do

    My mac book pro does not connect but shows an error message with a question mark on the screen.I took it to a retailer that said it was not reconizing the hard drive.He said i needed a new hard drive but it may be something else as well but he was sure a new hard drive would fix it.So putting faith in someone who deals with them i purchased a new hard drive to find it was still not working although he said the computer did know reconize the hard drive and i may have to send it away to get it checked .After already paying 120 pounds for a new hard drive and they wanting another 80.00 pounds to diagnose it i am a little sceptical.
    That's why i am interested on anyone's help.

    Welcome to the Apple Support Communities
    I think that your Mac detects your hard disk, but the problem is that your new hard disk doesn't contain any operating system, so your Mac doesn't find any bootable partition and you see a question mark.
    If your Mac came with DVDs, insert the Mac OS X Install DVD and hold the C key while your Mac is starting. Then, just install Mac OS X. If the hard disk isn't prepared to install Mac OS X, you will have to erase it using "Mac OS Extended (Journaled)". See > http://pondini.org/OSX/DU1.html

  • My Mac book pro (2011) start-up goes straight to disk utlities and wont install mavricks.

    Hello,
         My mac boook pro 2011 wont start up to my internal harddrive. it will sit on the white screen for a bit before it takes me directly to the choose language then disk utlity and shows the;
    Time machine
    install osx
    get help online
    disk utlity
         Ok so my harddrive is partitoned into two, but everytime i try to delete the partition drive, it wont let me. says (Macintosh HD2 cannot unmount please try again). And everytime i try to earse the free space, it wont do it as well. but its says it did.
         Then i try to repair my disk but my verify/repair disc permissions is not choosable but the veriy/repair ARE choosable. i choose verify/repair option and it says everything is fine. but it still wont let me choose verify/repair disk permission. My Saftey Mode is not working ( circle with line through) so i cant fix that problem. I also done the reset PRAM/NVRAM and SMC and still nothing.
         Ok the problem goes further. my Mac book pro came installed with Snow Lepord not mavricks but it wants to install mavricks instead. I put my internet into some single thing and it switched it to Lion instead of mavricks. but that isnt the problem (just thought it was weird how it switched OSX system like that) the problem is that it doesnt want to download install any OSX system. First it didnt let me get pass the choose install drive wondow. , then i switched my date in the terminal and was able to sign in but it wont download any OSX system, it would say (Something came up, please try again). My install cd wont work, keeps spitting it out. And trying to do an OSX system download wont work through this browser on disk utltity (not enough space on the drive).
         I was deleting log files from my mac through the partitioned drive and i accidently deleted a system folder that had logs. i was wondering if this was the problem and if its making my HD fail ir is my HD done? and can i put Yosemite on a usb and boot it that way or burning it to a CD and doing a cd install?
         Please i need help becuase i use my mac for film and editing and my mac wont boot to the desktop, just to this window. ill try to post picutres of what happens.

    That you are getting the BONG is a good sign, it's unlikely to be hardware if you are able to hear that.
    Start by running SW update. It's not that there is a specific fix, but when updating it may rewrite some system files which may get this going again purely as a side affect. Worth a go, and should not harm the system.
    Try reset the PRAM - Resetting your Mac's PRAM and NVRAM
    Hopefully one of these quick fixes works, otherwise we'll need to try isolate the issue next - so if still having a problem, I'd try create a new user and login as that user to see if the issue persists (which will tell us if it's system wide or user specific)

    Erase and Install
    1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
    5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.

  • Mac book pro 13" 2010 beeps every 5 seconds at start up, will not boot up.

    my mac book pro 13" 2010 beeps every 5 seconds at start up, will not boot up. Any ideas what is wrong?  Removed and re installed memory, that did not work.         
    Thank You   ecbrum

    If you're handy with tools, pop the bottom pan on the Mac, take out the RAM sticks, thoroughly clean the contacts on both the sticks and the Mac (blow clean with a compressed air duster on the Mac, use isopropyl alcohol on the contacts on the RAM sticks), reseat and reinstall the sticks and retry. If same, try swapping the RAM sticks. If you need pictorial assistance, see here: http://www.ifixit.com/Guide/Installing+MacBook+Pro+13-Inch+Unibody+Mid+2010+RAM/ 4319/1

  • I just upgraded to the New OS on my Mac Book Pro and now my trackpad does not zoom in or out.  I looked at system settings on trackpad and it is set, but does not work How do I get it started?

    This is really unfortunate. I'm sorry that nothing works. I was going to mention holding down the power button and doing a force shutdown but you already did that. You might need to take it into the Apple store. I don't know if booting into safe mode would help. You would have to turn off the machine again, hit the start button and hold down the shift key after you hear the tone, but normally you would let go of the shift key when you see the apple logo and spining wheel. Maybe by holding down the shift key after you here the tone will cause the screen to come back on? The other option is to start up from the 'install disk' if your machine came with one. You would insert the disk, then shut down the computer, and hold down the C key right after hitting the start button.
    Here's the link for the safeboot

  • I am trying to upgrade my hard drive in my mac book pro using the disk utility in an attempt to clone my old hard drive.  I can only get so far, just before cloning may start and receive an "error 254" and can go no further.  Any idea what this error is?

    Connect the HDD to your MBP.  Open Disk Utility>Erase and drag the HDD icon inrt the Name field.  The format should be Mac OS Extended (Journaled).  Click on the Erase button.
    Then try the clone process again.  You may use Disk Utility>Restore or a third party cloning application such as Carbon Copy Cloner or Super Duper.
    Ciao.
