    Could you specify the model of MacBook and the OS X it's running, please? Some of the advice or references vary along with the system, so this could be helpful to formulate a reply. I've never used a Guest User selection, but do have more than one User.
    If the computer does not have an optical drive, you may be able to boot it into a recovery disk mode or something; in an attempt to see what is wrong and maybe fix it.
    Good luck & happy computing!

    Question (?) Mark, Blinking Folder, or Gray Screen at Startup
    These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
    A flashing question mark appears when you start your Mac
    Mac OS X- Gray screen appears during startup
    In most cases the problems may be caused by one or more of these:
    a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
    b. Boot drive's directory has been corrupted - Repair with Disk Utility.
    c. Critical system files are damaged or deleted - Reinstall OS X.
    d. The disk drive is physically non-functional - Replace the hard drive.
    Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
    Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here.

    Repair the Hard Drive and Permissions
    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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.

  • Last night I did an update and now when I turn on my macbook it just goes to the white screen with the apple and stays like that.

    Last night I did an update and now when I turn on my macbook it just goes to the white screen with the apple and stays like that. How do I fix this issue?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
    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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
    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 in OS X 10.9 or earlier, 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.

  • My iphone wont open, i even recovered it but to no avail, all it does is go to the white screen with the apple logo then turn off again

    Hey everyone,
    This morning i took my phone out of the charger and everything was normal however, once i got in the car i looked at my phone and realized it was turned off. I tried turning it on again as well but all it does is going to the start up screen (The white screen with the apple logo) and then it turns off again as well. I also put it on the charger but it does the same thing but repeatedly. So it just goes to the white screen and off again. At last i resorted to recovering my phone even if it meant losing all my data. Slow internet connection meant it took all night but in the morning i recovered and everything and got to the last step ( It told me its finished but i should leave my phone connected to itunes and it will pop up there) but all that popped up was an error screen. It still broken but now sometimes when i try to turn it on the same white screen with the logo comes on with a bar under it. this bar fills up a little then the screen goes black again. Is there any other way i can try to fix this?
    P.S. There are no apple stores in my area so i took it to one of the phone stores here and even they said they couldnt do anything about it

    Try:
    - iOS: Not responding or does not turn on
    - If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    Try this step and if you cannot get your device into recovery mode there is a chance you have a hardware failure and you need to call apple to see what service options you have.

  • HT4623 I downloaded ios7 and initially it was working fine. Now it is flashing from my home screen to the white screen with the black apple every 3-5 seconds. It's so annoying and I can't make it stop! I tried shutting down all the way - nope! HELP!

    I downloaded ios7 on my iphone 5 yesterday. All day it worked fine, then last evening it started blinking from the white screen with the black apple to my home screen. Each screen only stays up for 3-5 seconds then switches back. I have tried shutting down and it is still happening! Does anyone know how to fix this issue without having to go into the store?

    Your power adapter is OK. If the only place it will not work is in your home, your house wiring and / or the appliances connected to it are likely to be the reason your Mac will not charge.
    From Troubleshooting MagSafe adapters:
    Identify line noise issues.
    Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in.
    If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter's "over voltage protection" feature senses ground noise and then turns off the adapter.
    Some possible sources of line noise include lights with ballasts, refrigerators, or mini-refrigerators that are on the same electrical circuit as your computer. This behavior may not occur if you plug the power adapter into an uninterruptible power supply (UPS) or plug it into a different circuit.
    Unless the adapter continues to exhibit this behavior on a known good outlet, it does not need to be replaced.
    Household wiring problems are very common. They can also be very dangerous. Fortunately most problems can be easily fixed by a qualified electrician.

  • Hello. When I connect my imac Start, as usual, comes the start signal and then the white screen with the load signal then nothing happens. What could be the problem?

    Hello. When I connect my imac Start, as usual, comes the start signal and then the white screen with the load signal then nothing happens. What could be the problem?

    Presuming you get the chime, most of your Mac hardware is working and has passed the first part of the power-on self-test.
    If the screen comes on, basic graphics is working.
    The dark gray Apple is not present inside the Mac -- it must be loaded from a boot device. If the dark gray Apple appears, at least one of your boot devices has some capabilities. The flower petal/gear moves while Darwin is initializing and loading. If it stops immediately, something is terribly wrong.
    When the screen turns blue, Mac OS X has loaded and your graphics card transitions to Interrupt-driven operation. LoginWindow task draws the login screen, and Mac OS X is ready for login.
    What could be the problem depends on where in the process it stops, and whether the power light is blinking.

  • Help! I'm stuck on the white screen with the gray apple!

    I just got an iMac g3/500 indigo, I think it has OS 10.0.4 installed. When I first turned it on it started fine and went to the password page. I did not have the password so I turned it off called the person I got it from, got the password. When I turned the G3 back on all I now get is the white screen with the gray apple. I tried to start in safe mode, it starts to load but then tells me I need to restart. I do not have the original disks, I do OS 10.3.2 disks but they are the DVD version and do not seem to work on this G3. What can I do? I am stuck, can someone please help? Thanks

    Hi Frey
    If your indigo has firewire (which I think it will have) see if you can borrow an external firewire DVD-drive. You can boot the iMac from that.
    There may be one slight problem though with firmware (not firewire). I forget at the moment which version it is but installing 10.3 (I think) without updating the firmware first gives you blank screen and renders the mac unusable until you can get it fixed.
    The problem is that firmware can only be updated while running OS9 "from the internal HD".
    You end up with a catch 22 situation where you need OS9 CDs in order to install OS10.
    The likely-hood of the iMac NOT having OS9 on it already is slim - no-one in their right mind would run an imac solely in 10.0. So you have to work out a way of getting started in 9.
    See if you can locate an OS9 start-up CD - doesn't have to be an Apple one- Norton Utilities or TechTool Pro will do. Just get the mac started and then go to the control panels (under the Apple menu) and select start-up disk. It should (after a pause or two) show you all the viable startup systems on the mac. If you still can't get going you may have to rebuild the HD using one of the aforementioned utilities disks - though I would use DiskWarrior for that in preference to both of the others.
    Let us know how you get on.
