Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • Power mac G5 turns on but will not boot up

    Hello,
    I have the last power mac G5 quad core made before apple switched over to intel. I have not used he computer in about 3 month and it worked fine when I put it into storage but when I tried to turn it on today it will not boot up.
    There is constantly a yellow light on near to where the RAM snaps in even when the computer is off. (this is the 3rd light up from the bottom and the only on that is on at this point)
    When I press the power button a red light turns on for about one second. Next to this light are the words LED806 Checkstop and it is offset to the right of the other lights a little bit when looking into the side panel of the computer. This light also lights up briefly when I press the power button to turn off the computer.
    After pressing the power button another red light turns on just above the yellow light that is always on and the screen is still black. Then the screen eventually turns grey with the apple logo as it normally looks except some of the pixels are off colored a bit in square patterns across the screen. When this happens a green light turns on just below the yellow light. Now there are three lights on all at once.
    Next the screen briefly turns light blue and then a little darker shade of blue and the computer will not boot up or go any further than this point.
    Can anybody tell me what is going on here and is there any way to fix this?
    Is there any way to reset or reboot the computer this the install disk?

  • My ipad turns in but will not boot up. screen stays blank. I've tried resetting it and rebooting from itunes. It says it is done but the screen still stays blank. The apple icone will show up intermittetly.

    I turned on my ipad after charging it and the screen went blank. I tried the home button and on off button and that did not help. I went to iTunes and rebooted the ipad and restored it and it asked me to reboot from the ipad but the screen is still blank. It will go to a blue screen if I hit the on/off button. What else is there to check?

    If you restored the iPad, there is nothing else to check. I suggest that you make an appointment at an Apple Store Genius Bar and let them evaluate your iPad.

  • MacBook Pro Turns On, But Will Not Boot

    I recently have had trouble with my MacBook Pro (2.4GHZ Duo Core purchased in late '07).  Last night before I went to bed I put my computer to sleep after normal usage of my computer.  I did not update anything such as firmware or progams in the past few days.  I had it connected to a WD external drive and an external monitor as I have for months.  When I went to wake up the computer this morning it would nothing appeared on the screen as it normally does.  I waited and tried different things, but no luck.  After a minute or two, I just turned it off by holding the power button down.  After a moment or so, I turned it back on.  The cd-rom drive spun up, but the computer did not post (chime), hard drive seemed not to be active, and nothing appeared on either the external display or the internal LCD.  I then turned off the computer again.  I disconnected everything, removed the battery for a few minutes and then tried to start it again.  The same result appeared each time: cd-rom spins up, no hard drive activity, no display.
    I tried various things that was suggested in the Apple Support area such as resetting the PRAM & SMC, as well as trying to get it to boot in safe mode and entering the BIOS.  Nothing.  Before I take it into the Apple store to have it looked at since it is very far away, I was wondering if anyone had any input on what could be wrong and if I am able to fix it myself.  Thank you.
     

    It's possible that you have the NVIDIA problem:
    http://support.apple.com/kb/TS2377
    Not really sure why it won't boot at all. People have reported suddenly getting no video at all, but I think they usually do get the startup chime.
    Probably the best bet is to make the trek to the Apple Store, as this sounds very much like a hardware problem. They should be able to test specifically for the NVIDIA problem.
    Good luck!

  • My macbook pro will turn on but will not start up.

    My macbook pro ['08 Silver keys] will turn on but will not start up. Screen is black and keyboard is unresponsive, besides power button. Help!

    ugh, no chime is not good, as that means it is not getting past the firmware POST phase.  Is the sleep light blinking fast?
    One thing to try is to access the RAM slots, remove, then replace and reseat the RAM.

    Try booting in Safe Mode by holding your Shift key down when booting. Also, try holding the eject key down when booting to eject the DVD. If you plug a mouse in and hold the clicker down when booting, that should eject the DVD.

    Yes, This is a New Build, though Windows XP is already on the Hard Drive From a Previous Build. I Had a K8N Neo Platinum Motherboard with ATHLON64 3400. MB caught the hiccups and I changed everything out. So My Hard Drives have to be reloaded but not wiped??
    Yes, that is necessary. Also leave only one HDD temporary where you planing to install your OS, when installation is done then attach your other HDD(s).
    "So My Hard Drives have to be reloaded but not wiped?"
    No need to be wiped, only Windows re-installation.

    Yes the original Install Discs can be replaced for a nominal fee. Call AppleCare, you will need a credit card and the serial number of the machine. You can use the AppleCare Contact Info for the phone number on your part of the planet.

  • My iMacG5 will only boot to white screen, gray apple and spinning gear. Help?

    My iMacG5 will only boot to white screen, gray apple and spinning gear. Help?
    Also not totally sure if it's an Intel based computer, but that's what I recall. Any way to check, since I can't get to About This Mac window?
    It's running on OSX Leopard 10.5.4
    First symptom = running slowly - then it kind of froze with color wheel spinning - thought a forced shut down would help - help power button til off, then white screen, gray apple and spinning gear.
    Have tried...
    1. Turn off the computer by choosing Shut Down from the Apple menu, or by holding the power button until the computer turns off.
    2. Unplug all cables from the computer, including the power cord.
    3. Wait 10 seconds.
    4. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
    5. Let go of the power button.
    6. Press the power button once more to start up your iMac.
    Then try booting from your install disc again.
    - No change
    And...
    Booting From An OS X Installer Disc
      1. Insert OS X Installer Disc into the optical drive.

    You need to do an Erase and Install or an Archive and Install depending on whether the hard drive is OK or needs to be reformatted.
    Start by booting from your Leopard DVD. The rest is just following directions.
    How to Perform an Archive and Install
    An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
    Repairing the Hard Drive and Permissions
    Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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. Now restart normally.
    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.
    2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
    3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
    4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
    5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
    6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

  • 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.

    Hey Gurus I've just shot a seminar, three cameras, Cannon's reasonably new XA20HD's. File format 1920X1080 MP4 17mbs 25 frames. Am running PremProCS6. I import the files into Prem, they come in ok but will not display. Got a yellow bar and a yellow Media Pending screen. What the? Have to cut this stuff soon! Wont even import into Media Encoder. Says there are no usable streams in the media! Just saw a podcast title about stress in the editing business. Better listen to the one! Any help would be most appreciated. J.

    Copy ALL contents of SD card to a folder on edit hard drive. not just video clips, everything. Then in Premiere, import using Media Browser (tab at lower left of Premiere screen). This usually does the trick. There is metadata contained in the SD card files that is needed, not just the video clips alone.

    I want adobe flash.  Ipad2 will not accept it.  Adobe blames apple and apple blames adobe.  I don't care.  Just fix it.

    Hello Pepperbrewer,
    While there's no way to get flash on your iPad and probably never will be, you can use several things to help you access some flash products.
    1) Skyfire for the iPad is a web browser that will convert flash videos and allow you to play them on the iPad.  Simply purchase it from the App Store and then you can use it instead of Safari when you want to view flash videos.
    2) SplashTop for iPad will allow you to remote control your desktop or laptop computer and use it from the iPad.  You basically install the SplashTop software on your computer, set it up, then load SplashTop on your iPad and it will allow you to use the computer from your iPad -- that means you can do anything your computer can do.
    I'm guessing in your situation Skyfire will be the best option for you.
    Fortunately the popularity of the iPad/iPhone/iPod is forcing a lot of major sites to use non-flash options, so in the next few years we may not care that flash isn't available.
    Adobe is also working on a lot of tools, and have some available now, that will help sites switch away from Flash to use HTML5 instead.
    Lastly, you're welcome to follow the other suggestions and find a buyer for your iPad 2. If you do choose to do that, I would recommend you spin the product positively, as you will get much less money for it if you let your frustration bleed off on the new buyer.
