I am trying to resolve an issue on my Macbook Pro. Using Disc Utilities, I need to boot from the Recovery HD. I did so, then restarted the computer and after the chime press and hold down the COMMAND and "R" keys until the computer starts up. However, when I do, no Recovery HD appears.


MacBook Pro, OS X Mountain Lion (10.8.2)

    It is not clear if you start in Recovery mode or in the usual way

     

    This is what recovery screen looks like

    Using "the usual way" to get to Disk Utilities shows that I have a corrupt disk. Using the Recovery mode shown above I ony have the high level Macintosh HD and the startup disk, Mac OS X Base System. Neither show a corrupt disk when I run Repair. However, when I load Safari using a normal bootup, the crash continues each time I use it.

     

    For reference, neither Firefox nor Chrome fail at all, so the problem must have something to do with Safari.

    Some Macs do not have the capability to start from Command+R and you may need to make a USB Recovery drive to boot from. Look here for more information if you want to see if you can use Lion Internet Recovery (boots from Apple's servers if the local recovery fails)

    That is completely false. All Mac computer that have Lion or Mt Lion installed on them have the ability to start the system from the Recovery HD partition using the Command+r keys. That is if they have a Recovery HD partition on a drive connected to the system. Whether that drive is internal or external.

    Edit: The Recovery HD must be on the internal drive.

     

    Some Mac computers do not have the ability to use the Online Internet Recovery system which is the Command+Option/Alt+r keys.

    But if the system has the Recovery HD partition using the Command+r key will boot to it.

    That is not the case of the OP, because he can start from Recovery HD.

     

    Creating a USB Recovery drive requires having the Recovery Partition on the computer.

     

    Note: In order to create an external OS X  Recovery using the OS X Recovery Assistant, the Mac must have an existing Recovery HD.

    Is only Safari crashing or the complete system?

  • DenaliDad Level 1 Level 1 (0 points)

    Only Safari crashes. I have no problems with any other application.

  • Alberto Ravasio Level 4 Level 4 (3,535 points)

    So, the subject of this thread is misleading.

     

    From Finder menu select Go, press and hold the alt key select Library.

     

    Open Saved Application State folder, move the folder com.apple.Safari.savedState on the Desktop

     

    Launch Safari. Does it crash?

    Shotgun00, I agree with Alberto. My computer does not start from Command-R, but I have Lion installed. I actually had to make a bootable USB drive for my computer to boot from it. Some computers just don't have the capability to start from Command-R. Also, there is no different shortcut between Internet Recovery and Local Recovery. The machine attempts to boot from Local first, and if that fails automatically goes to Internet.

    Well it is not Command-R (That would be the CMD key "Plus/Also" (and I'm not sure why you are typing the Minus sign) the Shift key and the r key "R"). It is the Command key "Plus/Also" the r key (No Caps) held down together just after the startup Chime sounds.

     

    If an Intel CPU base Mac can run Lion, is capable of running lion (Some can and some can't), it can start from the always included Recovery HD partition by using that key combo.

     

    Now there are some Mac's that will not start from that key combo but it has nothing to do with the base computer, model year of the Mac. It is because that Mac is using FileVault encryption. Because of FileVault that key combo is disabled. Otherwise you could boot to the Recovery HD partition and Erase the Encrypted partition.

  • Compukid Level 2 Level 2 (150 points)

    Well, I have tested Command-R (and it doesn't matter whether I use a minus or capitalize the "R" as long as the OP knows what I'm talking about) and it does not work unless I use my USB drive. And also there is no difference in the shortcut according to http://support.apple.com/kb/HT4718 .

  • Shotgun00 Level 2 Level 2 (220 points)

    What model year is your Mac? Is it an iMac with a USB wireless or Bluetooth keyboard? Do you have Filevault enabled?

     

    Then you are doing something wrong.

  • Compukid Level 2 Level 2 (150 points)

    April 2008, USB (tried Command-R on a bluetooth keyboard on another computer and it worked, computer is the 2012 model), no FileVault.

    EDIT: Yes, I have tried diskutil list which returned this:
    /dev/disk0    #:                       TYPE NAME                    SIZE       IDENTIFIER    0:      GUID_partition_scheme                        *500.1 GB   disk0    1:                        EFI                         209.7 MB   disk0s1    2:                  Apple_HFS Macintosh HD            499.2 GB   disk0s2    3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

    Whether that key combo works on another BT keyboard Mac doesn't matter. Are you using a BT or USB keyboard?

     

    Can you bring up the Boot selection screen by holding down the Option key? If not then you have a problem with your system or the keyboard.
