    I installed osx Yosemite along with mavericks. My MacBook was booting into Yosemite by default. In the system preference I change to target disk mode. Now when I restart my MacBook asks for a password (I think this is yosemite ui) it doesn't take my default password and now I don't know how to boot into some partition. I tried holding cmd r cmd s and none of the mode boots. All I get is password prompt. I am now posting from my iPad :( kindly help me

    If you are seeing something like this:

    then you have a firmware password set.

    There are 2 ways to go forward:

    1:

    • Insert your Mac OS X Install DVD into the optical drive of the Mac.
    • Restart the Mac using the Startup Manager: press and hold the Option key as soon as you hear the startup tone.
    • The Firmware Password prompt appears. Type the firmware password for the computer, then click the arrow or press Return. If you typed the firmware password correctly, the screen will change to show available startup disks, including Macintosh HD and the Mac OS X Install DVD.
    • Click the Mac OS X Install DVD. Then either click the arrow beneath it or press Return. - - The Mac begins to start up form the disc.
    • When prompted, choose your language, then either click the arrow or press Return. After a short time, the Install Mac OS X window appears.
    • In the menu bar, choose Utilities > Firmware Password Utility…. The Firmware Password Utility will load: be patient, as it loads slowly.
    • In the Firmware Password Utility window, click New.
    • In the Firmware Password Utility window, deselect Require password to start this computer from another source.
    • Click OK. The Firmware Password Utility window displays text indicating that the changes will be implemented after a restart.
    • Click Quit. Focus returns to the Install Mac OS X window.
    • Quit (Command-Q) the Installer. Choose Restart when prompted.
    • After restarting, firmware password protection is disabled. Eject the Mac OS X Install DVD from the optical drive and store it properly.

    2: Go to an Apple Genius Bar:

    Only Apple Retail Stores or Apple Authorized Service Providers can unlock computers protected by a firmware password.

    If you can't remember the firmware password for your Mac, schedule a service appointment with either an Apple Retail Store or an Apple Authorized Service Provider. If you plan to visit an Apple Retail Store, please make a reservation (available in some countries only).

    Hold down the ⌥ option key while you turn your computer on. That should bring you to a boot list where you can select Mavericks.

    osx - Mavericks freezing on boot
  • silvertriclops

    I updated my 2007 non-unibody Macbook Pro with 4gb RAM and 2.2ghz Core 2 Duo. It successfully installed, then the spinner froze on boot and the computer wouldn't start. I ended up just reinstalling Mavericks from scratch and starting over. But now, a few days later, I was just doing random stuff and the computer froze. It usually isn't a problem and has never been a problem for me before. This time, when I rebooted, the spinner on the boot screen froze again, and it just sits there for 5 minutes then shuts off. I can't boot in safe mode and I don't want to reinstall Mavericks and all my apps from scratch again. Is there anything I can do to get this thing to work??? Any commands I can run from recovery? Thanks ahead of time!

    UPDATE: I booted into recovery and restored from the most recent Time Machine backup. It told me to reboot so I did, and then I got this message. I didn't boot into verbose, it just did this. http://pastebin.com/rFaUtWfN

    After four days of testing, I found out that it was when I turned off the wireless (Airport). My laptop would totally freeze within seconds and every time I would try to reboot. When it still froze even after I rolled back to 10.8 I knew it wasn't a hardware issue.

    I found a fix on day 5: Do not turn off your Airport, Turn off your modem!

    Seriously, if it happens to you, get your Mac on target mode and browse your hard drive to:

    /Library/Preferences/SystemConfiguration/

    and rename the file "com.apple.airport.preferences.plist" to something like "com.apple.airport.preferences.plist~bad" and reboot.

    If you are in school, and have it running I would say keep it the way it is until you have some time to look at it. In my experience when you are having your specific issue with boots to spinning gear, then shuts down after a while it is an issue with the hard drive in specific. By the time that it gets to that gear in the boot process it is loading the boot.efi, and kernel extensions (Basically your actual software)... Meaning that it is trying to read what is on that disk. Which by your specs of your computer (Silver Key MBP) if that is your original drive.. Is probably getting pretty close to kicking the bucket. But you've done the smart thing and backed up. So, if you get more issues (slow (yes it's a 2006-07 computer it's gonna be slow) hard to start up, force shut down after sleep) it might be time for that new hard drive. Check out AASPs' to replace it, you WILL break your keyboard if you try it the first time. locate.apple.com will send you to a place that will do it, at cost. But you can get a pretty cheap drive on newegg.com
