  • My macbook pro shows blank screen when I started..help me..

    My macbook pro shows blank screen when I started . (It's like in same state when power off. ) fan sound and hard disk is running. So i connected it Through external monitor via mini display to VGA cable. I can see everything on external monitor. My display of Mac needs to change? How much it cost ?? I found so many forum discussion said that if nvedia card is faulty then its happen...let me know suggestions...I given it to apple care service station n they r telling yr display needs to change its cost me a lot.. I can't afford. And can't spend that much for 3 yr old version as new versions of macbook pro is cost vice reasonable.. can I have any suggestion?

    If running 10.7 or later hold down Command-R at Startup.
    This should invoke recovery Mode.
    Choose Disk Utility.
    Select your Hard drive. Inspect the SMART Status in the lower right of the window for "Verified".
    Select the Mac OS X Volume (originally Macintosh HD) click (Repair Disk)
    If errors, run again until it comes clean or gets stuck.
    Report any error messages.

  • My Macbook Pro Showing White Screen At startup

    Macbook pro showing white screen after loading window

    Krishnaraj7777,
    you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the  OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Do you get past the white screen now?

  • Early 2011 2GHz Macbook pro distorted blue screen then wont boot, 3 times in last 2 weeks

    I have an early 2011, 2GHz macbook pro (15' model with ati radeon graphics). It was running fine for the last two years. Over the last couple of weeks, following things happen:
    1. I was running on bootcamp windows, browsing and some flash content was open, suddenly distorted blue stripes appear and it froze. Force shut down using power button, turn on again and it wont boot on windows or mac, or recovery partition or from the dvd. Tried for about 4 hours, after nvram, pram reset, it was able to safe boot, then run disk utility to verify and repair the disk, it said that there were problems with hard drive and fixed,then booted normally.
    2. I thought that the problem might be because I was on windows, so took a back up of the windows drive, erased it and installed windows 8 using bootcamp. It ran well for an week. After that, once I connected it with the tv using HDMI to watch a video, after I disconnected it, the screen was garbled over the windows start screen, but I was able to command restart normally. After restart, it wont boot to windows or mac.
    3. After several hours of trying, i was able to boot using the dvd this time, it said it 'can not install mac on the hard drive', erased the hard drive and it was able to install the os (snow leopard). After completing install, logged in to app store to download previously purchased mountain lion. Then ran it to upgrade the os, after the upgrade was completed, at the point when it prompts for apple id and password to set up icloud, it again froze with distorted blue screen. Shut down forcefully. Then turn on again and it wont boot. After the white screen and the sound, it shows the apple logo and spinning wheel for a while, then a bright white screen and nothing happens.
    Can anybody help reading the symptoms?

    I have the Early 2011 2GHz Macbook Pro and I have the same problem too.
    I switched out the logicboard a month ago and today the graphics just went distorted.
    Any solutions? Now I'm thinking it is the Graphics Card.

  • Macbook Pro 2011 blue screen with loading icon

    I was using my 2011 15 in. (2.0 GHz model) Macbook Pro, when a blue screen popped up for a second or two showing a circular gray loading icon, then disappeared and it looked like I had just logged in. It started to load the dock and desktop icons and my startup programs opened, but it didn't look like it had restarted because it didn't ask for a password, and only lasted a few seconds including the blue screen. At the time it had happened, I was working on a very high poly model in Blender, which might have caused it. I just got this computer, so I really hope there is nothing wrong with it, but I also got a warranty on it, so if there is anything wrong I can bring it in. If anyone knows if this is serious or not, please tell me. Thanks.

    Thanks for your response, and since I submitted this question, the same problem happened again. This time I was playing Left 4 Dead 2 on Steam, so I'm noticing a trend where this problem only occurs when I'm working with 3D graphics, which is basically why I got the Macbook Pro in the first place, thinking it would be good with this sort of thing. Interestingly, though, I first played the game on this computer fine at fairly high graphics settings and got a good, steady fps for about an hour, but the second time, when this crash occured, I had only just started. This has gotten me confused and worried, and I'm wondering if I should bring it in to Apple, and if so, if they can fix it. Any answers would be great. Thanks!

  • Macbook Pro gets blue screen and resets itself?

    I have a 15in Macbook Pro, year 2008. I have Snow Leopard on it.
    I bought it refurbished online about two months ago however a few times it has done something none of my other Macs have done and I'm getting concerned. I will have it in sleep mode and when I try to wake it it is frozen. Next thing it does it go to a blue screen then it resets Safari and I have to open a new window and tabs.
    What is going on? I had two Powerbook G4's and neither ever did this. I would like to know so I can contact where i bought it since it is under warranty still.
    Thanks

    Thanks!
    Do you have a link? I did a search on APPLE and couldn't find it. I could be searching incorrectly but I put "install disc" in the search engine.
    It has been doing it more often and the place where I got said we didn't have the warranty so they won't help. My fiancee got this for me and I was on the phone telling him what to click and he added the warranty but it doesn't show on my purchase order so they won't help. To be honest I don't really want to send it to CA for repairs, I'd rather go thru Apple to get it fixed or looked at. IDK what happened with our order because I know he put in for the warranty and a RAM upgrade (which I still want as well as an HD upgrade) that isn't on here either which I just found out a few days ago when I looked at what the RAM was for school. It's not that big of a deal things happen when ordering online and I dont mind buying the discs if I knew where to get them.
    My concern is being the motherboard and if that is what the issue is. That term alone sends chills down my spine, I dont have the best luck with them! The only error message I get sometimes is a CPU error and I haven't a clue what that means. I did pay for a 24hr diagnostic on it before we got it, can things or issues show up later on? I don't do anything crazy online like DL. I only stream Netflix and that is about it.
    So Im just at a loss as to why this screen is coming up and why it resets my browser and goes to the desktop screen where I have to reopen all windows and tabs.
    Anyway, thanks for your reply. I will try to look more for the discs but if you have a link that would help.

  • My mac will restart & show Blue Screen when plugged ipod classic into my mac

    When i plugged ipod into my mac and i put to the Disk Mode my ipod , the computer will restart & don't let me to restore my ipod !!!! Please help and give me a solution !!!
    My ipod & mac info :
    iPod Classic 160gb (2009)
    Mac Book Pro (2011)
    iTunes 11.1.3

    If your computer is  a 2011, you can stop the blue screen by turning off graphic card switching.  Under apple, system preferences, energy, uncheck box.  Temporary fix.  Your logic board may need to be replaced if you are under warranty or have apple care otherwise $1000.00.  May be software or firmware problem but apple has provided no info.  Replacing logic board has corrected problem for some users and not others.  Everything I've mentioned only applies to 2011 MBPs.

  • Macbook Pro 17" Black screen when selecting Windows 7

    I got a Macbook Pro 17", late 2010 that has been experiencing an issue when selecting Windows 7 as my Boot OS. This is an intermittent issue. It happens like once every 8 or 10 usage. I already took it 2 the Apple Geniuses twice and I was turn around because, They say, They don't do Windows.
    At this point, I'm hoping that Apple will come out with a Firmware Update or anything that will fix this issue. I know There are other users in the same boat as me or worst waiting for Apple to come out with a remedy.

    You might want to reformat and re-read what you had.

  • My Macbook Pro crashes(Grey Screen) when i unplug my 3G USB Dongle

    Not sure if this has happened to anyone else, but just after I installed Yosemite my 3G USB dongle Huawei K4305 Vodafone is not working anymore and when I unplug the dongle my macbook Crashes.
    I have installed the latest firmware and software for the dongle.
    I have done the hardware diagnostic on the Macbook, everything is working and the dongle is working fine as I tested it another Macbook with Mavericks and it works.
    I tried to reinstall Yosemite but my machine just hangs on black screen and won't reboot.
    MacBook Pro 13" 16GB Memory, i7 2.9Ghz 750GB HDD

    HI vojtabe,
    What I did was, I uninstalled the Vodafone software completely first, then restarted the mac, then installed the Huawei driver and connected up the USB dongle and did not select to install the software and i just pushed the eject icon in finder and unplugged it, and it never crashed my machine after this.
    Don't install the software as currently the Vodafone software only goes up to Mavericks.

  • Macbook Pro had blue screen of death.  Now hard drive wont wake up.  HELP!  Computer keeps freezing and crashing.

    About a month ago, the "beach ball" appeared on my screan.  I rebooted the computer only to a blue screen.  Was instructed to Safe Boot and repair my files.  I got the computer to let me in.  My only problem now is, when i open the mac, my hard drive does not make the wake up noise?  Im not so computer savey so im not sure what im experiencing.  My mac also sees the "beach ball" on occasion followed by it freezing and me having to hard reboot it.  What am i experienceing?!  Also when computer is booting up, a black screen with white lettering jimbo-jamble appears for a solid 30 seconds to a minute.  I am worrying because my macbook was bought refurbished about a year ago, never had ANY problems, and JUST LIKE THAT...i got a world of issues.

  • MacBook stuck on blue screen when starting up?

    So I started my MacBook the other day (running Tiger) and it was stuck on the blue screen (with the apple logo) for a long time. I figured it was just slow and left the room. Came back about 15 minutes and it was still stuck. Went to the following site:
    http://support.apple.com/kb/TS1411#symp1
    and tried starting in solo mode, etc and made it all the way down the list till it said try Disk Utility (not exact name I don't think) so I put in the Install disk that came with it and attempted to repair it. It said it was unable to repair due to a node error or something along the lines.... I gave up and am reinstalling OS X (Erase and start again is what I did which is okay as I have no personal files on that computer, I keep them al on my iMac and backed up on my Time Capsule) not to go off on some rant but my question is will the computer fix whatever a node is by completely erasing the hard drive and starting over? It's only at 22% complete so I'm not sure yet. I consider myself fairly computer competent but can someone explain what a node is and how it got messed up?

    Yes and erase and install will fix ANY type of software issue you are having. A node is something used to build data structures, if there is an error or one is corrupted it will affect the whole data structure, but no worries, the E&I will fix this issue.

  • My MacBook Pro shows the logo in a white screen when I ask for a Software Update under the apple. Actually it stays blank on Featured, Top Charts, Categories and Purchases as well. What up? Thanks.

    My MacBook Pro shows the logo in a white screen when I ask for a Software Update under the apple. Actually it stays blank on Featured, Top Charts, Categories and Purchases as well. What up? Thanks.

    I am having exactly the same problem right now. After some research, it looked like my HD was toast. I replaced it today, that part was easy, but now I cannot seem to use my original Install Disk to format the new HD. I get a grey restart screen, or if I get to the Language Selection screen, my cursor is frozen in left corner and I can't use it.
    Very frustrating, hope someone else has some ideas!
    PS My MacBook was about same age, and "expired" in exactly the same way as yours.

  • My MacBook Pro shows a grey screen  at start-up how do I fix this problem?

    My MacBook Pro shows a grey screen when I try to login and won't go onto my homepage. Why has this happened and how do I fix it?

    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.
