i was trying ubuntu 12.10 on my Mac in a live environment the other day, and as usual the fans were spinning very fast and the system got hot. So i rebooted into OS X and then while using the Macbook, the fans started spinning unusually fast! So i long pressed the power button and it turned off. when i rebooted however, it flashed the little LED (i think thats what its called, on the right side of the front) rapidly and beeped. then after like 20 seconds, the chime but as soon as it had chimed, the mac rebooted and repeated the chime-reboot about 4 times. Then it boots up normally into OS X. I read online about manually flashing firmware but alas, no joy. Now my Mac just crashes anyhow and even if i try to use it by keeping it on sleep all the time, it just wont wake or it just crashes. Please help, i have no warranty and i dont live in a country where we have an apple genius bar or the like .

    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.

    hey, i dont have a fast connection, but i have the install DVD. tried all the methods you said at least 4 times, hence the delay in replying because i wanted to exhaust all options. still no joy. Still the chime, shutdown, reboot, shutdown and only boots on the 4th chime. could it be my firmware maybe? tho i do have the latest EFI for my Mac.

    I assume you mean the Snow Leopard DVD? If so, then reinstall it if Snow Leopard is currently installed on the computer. If not, then you would have to erase the drive to install Snow Leopard. If you have Lion or Mountain Lion on a bootable flash drive or DVD, then boot from that to reinstall.

     

    Reinstall OS X without erasing the drive

     

    Do the following:

     

    1. 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.

     

    2. Reinstall Snow Leopard

     

    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

     

    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

     

    Downgrade Lion/Mountain Lion to Snow Leopard

     

      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. Set the format type to Mac OS

          Extended (Journaled.) Click on the Options button, set the

          partition scheme to GUID then click on the OK button. Click on

          the Partition button and wait until the process has completed.

     

      4. Quit DU and return to the installer. Install Snow Leopard.

     

    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.

     

    If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions.  If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

    hey, i give up. it wont downgrade, because it came with OS X so apparently it wont downgrade. Now, it crashes anyhow, wont wake from sleep and just freezes during use and still has the beeping issue. I guess i'll just have to pack it away and let it RIP lol. Six months only and its dead already, my mum will kill me! Thanks for the help tho

  • 5. Re: MacBook Pro 8,2 wont boot after Ubuntu live test and long press shutdown

    It won't downgrade, most likely, because it needs a version of Snow Leopard greater than 10.6.3 which is the last retail version released.

    So, the problem i have, is it something to do with teh hardware? or is it my EFI firmware?

  • 7. Re: MacBook Pro 8,2 wont boot after Ubuntu live test and long press shutdown
    Kappy Level 10 Level 10 (226,760 points)

    It's your hardware. Your model must have been released with Snow Leopard 10.6.4 or later. You should have the needed version on the original discs that came with the computer. If no discs came with the computer then it came with Lion or Mountain Lion pre-installed. If this is the case then see the following:

     

    How To Run Snow Leopard On A New Mac

     

    This does not apply to new Mac Minis or MacBook Airs. When newer models are introduced that also require Lion for hardware support, the techniques described below will no longer work with the possible exception of using Parallels 7.

     

    What has to be done:

     

      1. Create a new partition on the hard drive.

      2. Get a clone of a 10.6.8 Snow Leopard system. Put the cloned Snow Leopard

            system onto the new partition.

     

    Step One: Create a new partition on the hard drive

     

    To resize the drive and create a new partition do the following:

     

      1. 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.

     

              After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window. 

     

    2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.

     

    PartitionTableinDU.png

     

    3.           In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)

     

    4.           Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.

     

    You should now have a new volume on the drive.

     

    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.

     

    Step Two: Obtain a clone of a Snow Leopard system:

     

    You will need access to a Mac already running Snow Leopard. You will need a 16 GB USB flash drive or an external hard drive to which you can clone the Snow Leopard system from the Mac that has Snow Leopard installed. Alternatives are:

     

    Option One:

     

    Install a new Snow Leopard system onto a USB flash drive. Boot the Mac used for installing with the USB flash drive. Update the flash drive system to 10.6.8 using the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard. Verify that you can boot the Mac with the USB flash drive.

    Take the USB flash drive to your new Mac and try booting from it. If it works then clone the system from the flash drive to the newly made partition:

     

              Clone using Restore Option of Disk Utility

     

      1. Open Disk Utility from the Utilities folder.

      2. Select the destination volume from the left side list.

      3. Click on the Restore tab in the DU main window.

      4. Check the box labeled Erase destination.

      5. Select the destination volume from the left side list and drag it to the Destination

          entry field.

      6. Select the source volume from the left side list and drag it to the Source entry field.

      7. Double-check you got it right, then click on the Restore button.

     

    Destination means the new partition on the internal drive. Source means the USB

    flash drive.

     

    Option Two:

     

    If you have a large enough external drive you can erase and use, then it would be easier to just clone the entire Snow Leopard system from the source Mac computer to the external drive.

     

              Clone using Restore Option of Disk Utility

     

      1. Open Disk Utility from the Utilities folder.

      2. Select the destination volume from the left side list.

      3. Click on the Restore tab in the DU main window.

      4. Check the box labeled Erase destination.

      5. Select the destination volume from the left side list and drag it to the Destination

          entry field.

      6. Select the source volume from the left side list and drag it to the Source entry field.

      7. Double-check you got it right, then click on the Restore button.

     

    Destination means the external drive. Source means the Snow Leopard Mac's

    internal drive.

     

    After cloning verify that it will boot the source Mac. If so then take the external drive to your new Mac boot with it. If all is well then restore the clone to the new partition on your new Mac:

     

              Restore the clone using Disk Utility

     

      1. Open Disk Utility from the Utilities folder.

      2. Select the destination volume from the left side list.

      3. Click on the Restore tab in the DU main window.

      4. Check the box labeled Erase destination.

      5. Select the destination volume from the left side list and drag it to the Destination

          entry field.

      6. Select the source volume from the left side list and drag it to the Source entry field.

      7. Double-check you got it right, then click on the Restore button.

     

    Destination means the new partition on the internal drive. Source means the external drive.

     

    You will need a retail copy of Snow Leopard. If you need to purchase Snow Leopard contact Customer Service: Contacting Apple for support and service. The price is $29.00 plus tax. You will receive physical media - DVD - by mail.

    Oh snap! The need to have another Mac to do the snow leopard install won't be possible. I tried buying 10.8 and upgrading but still, same sequence of 4 reboots and then a final boot. That's the weird part. I'm starting to think its my HD. I'll get it replaced and see. If that doesn't work, guess next year in march when mum travels she'll take it to the geniuses. Hopefully I don't need to replace parts that would suck.
