I went to use my macbook pro and it was stuck on the boot screen. I reintalled Mac OSX Lion and i got it to boot up but with problems. The screen will blink around every 15 to 20 seconds and the computer is real slow. I ran a hardware test and it passed indicating no problems with the hardware. The computer did seem to get a little hot but never gave me a problem before. Any input would be greatly appreciated.

 

 

Macbook Pro

13" Early 2011

2.3 GHZ Intel Core i5

4gb 1333 DDR3 memory

Intel HD Graphics 3000 384 MB

Mac OSX Lion 10.7.5

 

 

Thanks

    Install or Reinstall Lion/Mountain Lion from Scratch

     

    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.

     

    Erase the hard drive:

     

      1. Select Disk Utility from the main menu and click on the Continue button.

     

      2. After DU loads select your startup volume (usually Macintosh HD) from the

          left side list. Click on the Erase tab in the DU main window.

     

      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on

            the Security button and set the Zero Data option to one-pass. Click on

          the Erase button and wait until the process has completed.

     

      4. Quit DU and return to the main menu.

     

    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible

                because it is three times faster than wireless.

    Can i back up the computer in safe mode?

    Yes, why? Are you only able to boot into safe mode? What do you have available with which to do a backup? All you need is an external drive large enough to hold the contents of your HDD. You can use Disk Utility to perform the backup.

     

    After booting to the Recovery HD per the above and run Disk Utility just don't yet proceed further. Instead do this first:

     

    Clone using Restore Option of Disk Utility

     

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

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

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

          entry field.

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

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

     

    Destination means the external backup drive. Source means the internal startup drive.

     

    After the clone is completed you can then move on to erasing the drive and reinstalling OS X.

    Ok, i tried to back up via time machine and it didnt work. Also got an error using the clone process.

     

    Error reads- Restore Failure- Could not restore, input/output error.

     

    Is there other way to back it up?

    How is your external HDD formatted?

    Sorry for the ignorance, but I dont know. Its a toshiba 320gb external HD. I do have some files on the HD from my macbook air.

  • 8. Re: Macbook Pro Problems
    OGELTHORPE Level 7 Level 7 (25,720 points)

    Can the Macbook Air or your MBP read and write to the external HDD

     

    Or put another way, can you drag files on and off the HDD when connected to the Macbook Air and the MBP?

     

    Ciao.

    Yes, just moved the files of the HD to my macbook air because the clone process stated that would erase the HD.

    If you were to use the external HDD to transfer files from your MBP to the Macbook Air, then we know that the HDD is formatted compatible with Macs.

     

    Open Disk Utility on your MBP and select 'First Aid', and then select 'Verify Disk' and then 'Repair Disk' if necessary.

     

    Then select the volume and run 'Verify Disk Permissions' and if necessary run 'Repair Disk Permissions'.

     

    Post your results.

    Ahey7784, greetings;  Please start a new post.  Include the software (OS) you are using and the exact model MBP you have.
