How to do a safe reboot on my MacBook Pro when kernel panic message appears?

Are you trying to safe boot because you got a KP or are you getting a KP when you safe boot?
You boot in safe mode by pressing the shift key immediately after you hear the boot chime.

  • I can not boot my MacBook Pro. How do I get and save the data that is not backed up??

    I can not boot my MacBook Pro running on Lion 10.7.4. I pressed control, comment P and R keys and O got to the disk utility, then I tried to repair disk and it can not be repaired. I get a message that tells me to back up as much data as possible ?. But if I can not open the computer how can I save my data??
    I have a back up until 2 weeks ago on time machine. but the work of the last 2 weeks is extremely important how can I get it??
    If I use m time machine backup do I loose the additional data of the last two weeks!,
    Please help.. It's a huge amount of work that I have done and can not loose it

    If it were me, I'd get a new hard drive or SSD and put it in an external enclosure. Boot into the recovery partition, format the new drive (not the old one) and install the OS to it. Shut down the Mac, open it up, and swap the drives. You may be able to read your data from the old one externally if you're lucky. If you're very lucky you may be able to use Migration Assistant to move all your stuff to the new drive.
    Look at ifixit.com for the exact procedure to get to the drive on your model. If it's a unibody it's pretty simple.

  • HT1338 how do I boot a MacBook pro that will not shut down

    HOw can I reboot shut don MacBook pro that will not shutdown, please help.....?......

    Hi, I'm having similar problem. I just got a Lacie ext drive to back up my photos and vids and now my laptop wont shut down or go to sleep properly.  May or may not be related to Lacie. Could just be a coincidence.
    I first noticed problem when I closed it to go to sleep and the apple logo kept flashing on and off.
    When I opened the laptop the screen was flashing white then black, then white then black.   Had to force shut
    it down (opt, cmnd,power), had to hold it down a very long time before it responded.  However, that didn't keep it shut down. It just started back up again.  But at least it wasn't flashing. 
    Then when i tried to shut it down normally it would shut down, go black for a moment and then the Apple song would play and it would start  back up again.    It also won't stay asleep. It sleeps for two seconds when put into sleep mode then snaps awake.
    strange problem... Very annoying. Next option is to unplug and let battery run out.

  • How can I restore my new Macbook pro to Factory setting?

    How can I restore my new Macbook pro to Factory setting?

    Install or Reinstall Lion from Scratch
    If possible backup your files to an external drive or second internal 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:
    Select Disk Utility from the main menu and click on the Continue button.
    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 Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    Quit DU and return to the main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Install button.
    Note: Be sure you have an active internet connection.

  • How do i back up my macbook pro to an external hard drive?

    how do i back up my macbook pro to an external hard drive?

    schmunzelmonster, greetings;  Your suggestion is a good one.  CCC does create a boot drive which as you point out can be most useful at times. Time Machine does not have that capability but it retains a history of activities and transactions that CCC does not.  CCC only retains information as of the last update.
    Neither individually is the 'perfect' backup solution individually, but if both are utilized it becomes that.  There is no harm in backup redundancy.
    My only complaint about CCC is that is is very slow in performing updates compared with Time Machine.  Just a nit on my part.
    Ciao.

  • Cannot boot my MacBook Pro. Tryed CMD+R, reinstall OS, error message :damaged HD. When trying to repait it says it's OK. Yesterday HD wasn't even half full when I turned it off, now it says it's full.

    Cannot boot my MacBook Pro. Tryed CMD+R, reinstall OS, error message :damaged HD. When trying to repait it says it's OK. Yesterday HD wasn't even half full when I turned it off, now it says it's full.

    What may have happened is an error and a kernel panic, filling up the logfiles.
    What I recommend is first to find a way to backup your data without booting the hard drive directly if it isn't already backed up, and then get Alsoft Disk Warrior to repair the hard drive.    You'll probably want an external drive from http://www.macsales.com/
    And you'll want to go into Hard drive -> Library -> Logs, System -> Library -> Logs, and Users -> yourname -> Library -> Logs to remove whatever you find there.   
    If after booting it fills up again, start by removing all startup items in your System Preferences for your user, and rebooting in safe mode with the shift key held down. If the hard drive is over 85% full after removing the logfiles, you may want to look at what were the last applications you installed.
    Peer2peer software if installed can be as bad as a virus, because it enables others to access your computer. Insecure wireless networks are just as bad, if they are WEP or no encryption and someone is within 1500 feet of your computer.
    If no such software is installed, your RAM probably has failed.    Run the hardware test that came with your computer, by booting with the 'D' key.
    If nothing shows up there, it can still be the RAM.   Especially if you've seen any 4 language screens telling you to restart.

  • HT201262 I have the gray start up screen that just keeps spinning. I have 'dubious permissions on file' I cant boot my MacBook Pro 15"

    I cannot start up / boot my MacBook Pro (15"). When I power it up, all I get is a 'persistant gray screen' with that gear icon spinning under the apple.
    I did run a 'safe boot', and saw that I had 2 possible errors that might be causing it:
    1) 'lanchctl: dubious permissions on file.  /Library/LaunchDaemons
    2) 'lanchctl: dubious permissions on file.  /etc./mach_init.d
    Also, there was a line that said that my 'IPv6' was disabled ??
    If anyone knows what I can do to fix this, I would be very grateful. All my songs and videos and pics are on my mac,and I have had it since 2007.
    Thank you kindly,

  • How to test security system on macbook pro 2009 13"

    Hello guys!
    I would love to know how can i test my apple macbook pro 13" security system?. I also want to know if its safe to have limewire running on the macbook pro?. Will this macbook notify me of any online security threats?. Thank you!!

    Download and run the freeware ClamXav if you can't shake the habit of checking for malware every week. After you've wasted fifteen or twenty hours running it a dozen times and finding nothing, you'll realize you're just being paranoid.
    To date there are no (zero) viruses that can infect Mac OS X. The only way you could have a trojan on your Mac is if you entered your admin password to allow it to be installed.

  • How can I connect an old macbook pro...

    How can I connect an old macbook pro with that does NOT have a Thunderbolt connection to a new 27 inch iMac? I only need to do this for one specific purpose, to be able to see the work I'm doing on the laptop in InDesign on the iMac's larger screen (at a larger size as it were, so I can see a double page spread (or even a whole page would be an improvement) in one go)?  I gather it might be possible to get an adaptor but note that Apple don't seem to sell one. I know I could do this with the cinema screen but would rather do it with a new imac as that will have more use to me overall. It's a work laptop which I don't own so I don't own the Indesign to just be able to use that on an iMac. I have tried to connect monitors to the laptop in the past, but with no success at all.  I hope someone can help . Thank you.

    Im pretty sure you are talking about the M8536 which has an ADC Adapter.
    you will have to daisy chain a thunderbolt to DVI adapter with an DVI to ADC Adapter.
    the first adapter:

    The second adapter is old so you may find used ones on ebay like this:
