  • My iMac won't boot up past the white screen with a grey apple and spinning icon

    My iMac won't boot up past the white screen with a grey apple and spinning icon...please help!

    command R did not result in anything different - still the white screen, etc. I do you Time Machine with and external hard drive, but I unplugged that.  I have the installation DVD, but it doesn't seem to be reading it either.

  • My 2011 IMac will not boot up past the White apple logo screen with the whirly circle

    My 2011 IMac will not boot up past the White apple logo screen with the whirly circle. I have tried various commands but to no avail. does anybody have any advice?

    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 Fusion Drive or 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.

  • Help!  Just did the Update (ML 10.8.4) after receiving a new HD since mine crashed last week, and now my Mac won't let me past the log in screen even with correct password.

    Super frustrated and any help is appreciated!

    I have decided to dedicate this thread to the wonderful errors of Lion OSX. Each time I find a huge problem with Lion I will make note of it here.
    Today I discovered a new treasure of doggie poop in Lion. No Save As......
    I repeat. No Save As. In text editor I couldn't save the file with a new extension. I finally accomplished this oh so majorly difficult task (because we all know how difficult it should be to save a file with a new extension) by pressing duplicate and then saving a copy of the file with a new extension. Yet then I had to delete the first copy and send it to trash. And of course then I have to secure empty trash because if I have to do this the rest of my mac's life I will be taking up a quarter of percentage of space with duplicate files. So this is the real reason they got rid of Save As: so that it would garble up some extra GB on the ole hard disk.
    So about 20 minutes of my time were wasted while doing my homework and studying for an exam because I had to look up "how to save a file with a new extension in  mac Lion" and then wasted time sitting here and ranting on this forum until someone over at Apple wakes up from their OSX-coma.
    are you freaking kidding me Apple? I mean REALLY?!!!! who the heck designed this?!!! I want to know. I want his or her name and I want to sit down with them and have a long chat. and then I'd probably splash cold water on their face to wake them up.
    I am starting to believe that Apple is Satan.

  • How do I back up my MacBook Pro from an external hard drive if my macbook won't boot up from the white start up screen? HELP!

    I went to the Genius Bar a week ago, and the guy helping me there was nice enough to help me save some money by telling me I could replace the bad hard drive my MacBook Pro had by myself. I bought everything I needed (hard drive, screws, external hard drive) and my computer won't boot past the white start up screen. It doesn't even show the Apple sign at the start up screen. How do I back up my computer so I can save all my music, school files, etc.? Could really use someone's advice on what to do! Thanks!

    Ok, to be sure I understand what's going on. You were able to boot the Macbook from the existing "damaged" internal drive, and it has been backed up to the internal.
    If that is correct, your internal drive is working. Just to be sure, try booting with the R key down. Then run Disk Utility to repair the internal drive. That drive may in fact be useable.
    You should be aware that you cannot boot the MBP from a Time Machine back up.
    Please post back so I am sure I am understanding the situation.

  • MacBook Pro won't boot up past the Apple logo! Help! :(

    I had to force the computer to shut down as it refused to force quit.
    I Have tried everything I can (Disk Utility - Repairing the disk.. even though the results came up as OK.. Ive re-installed Mountain Lion..) and had no luck!! The grey screen with the Apple logo and spinning wheel just stay there!
    Also, it refuses to go into Safe Mode, after holding shift the loading bar only loads up to almost half-way and then it disappears.
    Please help!! 

    I'm having the same problem with my macbook. Apple logo and spinning wheel.  I saw a video on youtube that said to reset prm and also to remove both sticks of ram and trying to boot one stick at a time (due to problem possibly being caused by faulty ram) I also tryed booting from disk and booting from safe mode, but everything has failed.  All I get is the Apple logo and spinning wheel.  Does this mean the hard drive has failed? Or is there another fix that I might try? If it is the hard drive it would suck, but I could go buy another one and replace it, but what would really suck is if it wasn't the hard drive to begin with.  Can anyone please help?
    Thanks....

  • After a liquid spill my laptop won't turn on but the sleep light goes off with a beep every 5 seconds

    It's been 2 weeks since I spilled tea onto the keyboard of my MacBook Pro- now after plugging it in the sleep light lights up and beeps every 5 seconds but will not start up- it has been upside down and powered down since spill

    Take it to Apple and ask them to find out what has been damaged by the tea.
    The longer you wait the worst the problems will get as the corrsion from the liquid continues to develop.

  • Laptop won't boot beyond the screen showing "Tobshiba leading innovation"

    I installed an antivirus recently and in its scan some viruses were found. Those viruses were deleted and now my laptop wont boot into windows. It just stays where "toshiba" logo is displayed. My laptop is running on windows 8.1. I have a recovery DVD, but the laptop won't boot from the DVD either. Is there a way to get my laptop to boot windows without doing a factory reset. Please help!!

  • Toshiba A665-S5170 laptop won't boot.

    My laptop will not boot. It won't even load past the "Starting Window." Just stays and loads forever. I have all the three recovery CDs, but I can't even get them to load up so that I can recover the system. Looks like it wants me to re-install the window disk which I have no clue on what it is trying to ask.
    Anyone know what's going on?

    So I talked to a tech, and he said I needed a new hard drive. He said that if it's a software program then I'll get a error pop-up. But if I get stuck at the a loading screen forever then it's the hard drive. So I went ahead and bought myself a new one for $115.00 including a 3 year warranty and shipping which isn't bad. I'll be doing the install myself and Best Buy quoted me $200.00 just for labor when I can do it myself as I'm a auto tech. So it's all in the mechanical aptitude.

    My MSI GT60 laptop won't boot past the MSI logo.
    I also can't access the BIOS.
    so your laptop freezes at MSI logo and if you spam or press DELETE button few times on boot do you then only get "-" line? if so then either it's bios has hanged itself so if your able to access cmos battery from back area where you can access hard drive, ram and such then disconnect cmos battery leave it disconnected for 15 mins also make sure ac and battery is disconnected to once done put cmos battery back and then actuall battery and try with starting the laptop and see if it passes by MSI logo if it hangs again at MSI logo then spam Delete and see if you can enter bios but if bios throws an black screen with "-" again then you would have to RMA your laptop since it sems something is wrong with your motherboard causing bios not wanting to work propertly.

  • Laptop won't boot up WITH PICTURE

    Hello! I'm sorry if this has been asked before; I tried to search for words that might be related, and it returned way too many for me to read through, or to guess if they're having the same issue as I am. 
    I have a A505D-S6968 Satellite laptop.  It is three years old, and I use it every day as I'm a graduate student.  For the past couple days, I go to turn the laptop on, and it won't boot up.  The power light is on, a bank of lights at the top near the base of the screen, a light near the bottom, and the charging lights on the lower right corner.  The fan is running, and the CD/DVD drive makes a sound.  However, that's where it stops.  The screen doesn't display anything and there is no glow from it at all.  The keyboard is supposed to light up, and it doesn't.  The mousepad doesn't light up or work.  So it seems like there's power being provided to it in some respects, as a few lights come on, the fan comes one, and the CD/DVD drive "checks".
    Here is a picture of it misbehaving:
    Any ideas as to what could be going on?  I let it sit, turned completely off, all night, because I figured I'd just deal with it later.  I had tried for an hour to get it to start and it wouldn't; it just sits like that indefinitely.  But this morning, it booted up just fine.
    Now I'm afraid to ever turn it off again!
    Again, I apologize if this has been asked a million times, but I can't read all of the descriptions and try to guess if what they're describing is what is going on with mine.  Any help or ideas are appreciated!
    Thank you!
    Grace & Peace,

  • Won't turn on past the startup sound

    Hello,
    I'm a student studying abroad right now in Senegal, part of Sub-saharan Africa (which might help for later on).
    My iBook won't turn on past the startup apple noise (the daaaaauummm). When I press the power button it makes that noise, along with a minimal amount of internal processor noise, and then nothing past that. The internal noise basically stops, and nothing comes up on the monitor. This problem started yesterday--I was using my computer and then the screen started to go fuzzy and get static and then it just went blank. Although I said that I don't get anything past the startup noise, I think my computer is still on (even though it isn't doing anything) because if I want to get the startup noise again I have to force shutdown the computer (hold down the power button for 10 seconds). Furthermore, when I do get the startup noise, the lighted ring around where the power adapter plugs in goes from orange to yellow and stays yellow for a bit. However, no light illuminates around the power button on the computer.
    At first I thought maybe there was a problem with my monitor. I followed two of Apple's troubleshooting steps, resetting my parameter RAM (I think holding control command P and R) as well as resetting my computer's PMU (shift control option and power button) and for both of those, I managed to actually get something on my screen--the apple with the gear around it popped up and stayed there, but then after about 3 seconds it got the same staticky and lines and then went black again. When I tried to replicate this by doing the exact same thing (for both solutions) I was not able to get past the startup sound (ie the screen stayed blank) and it was back to square one.
    Basically, I'm stumped. There are power cuts here in Senegal, along with subsequent power surges when the power comes back on, which lead my Dad to think that maybe my motherboard got fried. However, there is a power adapter on the cord which should block against that. Furthermore, that won't explain why the laptop was working right before it fritzed out on me, even though it was not plugged in. I'm thinking that maybe there might be a bug in my computer (like a physical one that crawled in). I am thinking this because there are bugs that crawl around my computer and under my keys (it's not as gross as it sounds--well actually I guess it is...) and furthermore I was out of town this past weekend so my computer was sitting idly in my room. Could it be that a bug actually made it deeper into my computer? But also, that still wouldn't explain why I was able to make it work on Monday.
    I will be here in Senegal for 3 more weeks, but I would like to use my computer before then. Is there anything I can try to fix myself here, or will I have to wait until I get back to the states. Is there anyway for me to al least get some of the stuff off of my harddrive--that's all I really care about? Obviously, there isn't an apple store here in Dakar, Senegal, for me to take it to--although there are a few computer places but it seems like Apples aren't too popular here, and so I'm not sure how effective/knowledgeable they'd be with a Mac. Plus I'd have to explain all of this in French, which wouldn't necessarily be the easiest thing.
    Thank you sooo much,
    Chris

    Hi, Chris. Welcome to Apple Discussions.
    It sounds like you may be having logic board problems. Enough Dual USB G3 iBooks suffered from this problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Check out the FAQ page and if the symptoms look familiar, give Apple a call.
    Since it is past the three-year time limit, try calling and ask for Customer Relations (NOT Customer Service--they can't help you) and ask them to please make an exception to the three-year limit in your case.
    You may want to consider trying the shim fix suggested by John Sawyer elsewhere here in the Displays Forum:
    [Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.
    John Sawyer
    CJS Macintosh Repair
    Instructions for removing the lower case:
    http://www.ifixit.com/Guide/50.5.0.html
    Once you get it fixed, try never to pick it up by the left front corner alone. Rumor has it that can contribute to logic board failure when the case flexes, causing the graphics chip to come loose from the logic board. If you're picking it up in your left hand (as I often do mine), pick it up in the center under the trackpad.
    Good luck. Let us know how things go.

    I have also tried to boot using the AC adapter alone yet my precious laptop isn't showing any sign of life.
    Please how do I fix this? I need to do my assignment and prepare for my exams, and I can't afford a new laptop. Not when the current laptop is pretty new.
    Please help me HP support.
    Thank you in advance.

    Hi @Chichiiii ,
    Thank You for your inquiry.
    I understand that when you power on your notebook it is unresponsive.  You did state that the AC adapter is working and the battery is charging.
    Here is a link to HP Notebook PCs - Computer Does Not Start (Windows 8), which has multiple links to help you determine the issue.
