Fix Permissions for a Locked Drive
Open Terminal in the Utilities folder. Paste the following commands at the prompt. Press RETURN after each. The first command will prompt for you to enter your admin password. It will not be echoed to the screen. After entering your password press RETURN again.
chflags 0 /Volumes/*
chmod a+rx /Volumes/*
killall Finder
An alternative is to download BatChmod and use it to fix the permissions.

  • How to unlock Macintosh HD in recovery mode?

    Good Evening,
    Have a little dilemma. Went to update my wife's Mac Book Pro to OS X 10.9.5 today and ended up in recovery mode. Looks like something messed up during the update. There are files that have not been backed up on the drive which makes matters worse. I have attempted to reinstall OS X Mavericks in recovery mode but it won't let me do it because the Macintosh HD is locked. How do I unlock this drive without erasing all the contents in it?
    Thanks,
    Scott

  • How to unlock logical Partition in recovery mode?

    I have problems with my iMac (2007) after installing 10.7.2. It's not starting any more. Now, in recovery mode in Disk Utility I've clicked on Turn Off Ecryption..., because my disk is encrypted with FileVaul2. The probelm is, it's showing now as Locked and I don't find any way how to unlock it. How can I unlock it again? Thanks.

  • How can I get out of recovery mode?

    How can I get out of recovery mode without restoring my iPod?

    Try using Yamipod.
    http://www.yamipod.com/main/modules/downloads/
    Make sure iTunes is closed before you use yamipod.
    Another issue I have heard about if are in Windows is a Parental Controls conflict with iTunes and your iPod trying to access the iTunes Server for the Restore Software Update.
    Make sure there are no firewalls blocking it if you are on a Mac.
    Try that, if not, post again.

  • How to fix iphone 5s stack recovery mode..Please help me

    How to fix iphone 5s stack recovery mode..i have tried So many ways and aloso tryed with  3rd party software but nothing happens...i trying with iTunes but error 14  message appare..i am from bd that's why in my country doesn't have any apple service center

    Error 14 is typically a hardware failure, but can be caused by security software...anti-virus, firewalls, etc. Given what you've posted, I suspect a hardware failure, & if that's the case, you won't be able to restore the phone. You'll need to find a service center to confirm.

    Thanks

    Hi aaaaherman,
    Welcome to Apple Support Communities.
    It sounds like your iPad 2 is in recovery mode and you’re running into an issue restoring it.
    Take a look at the article linked below which provides a lot of great information about recovery mode, including details about the restore process and what to do if the device isn’t recognized by iTunes.

  • How to recover iphoto library from recovery mode

    My macbook pro suddenly went on Utility Disk Mode and can only be accessed through recovery mode. I cannot even view the files. I'm willing to let everything go except for the photos and videos in the iphoto library. I don't know how to access my photos on icloud and when I did, it was just my iphone's photos that are there. is there any way I can view my photos in my locked macintosh hd in other devices or computer?

    Thanks for the response BDAqua, I did use Migration Assistant to transfer her data from the SuperDuper backup.  Are you suggesting that I use Migration Assistant to transfer data from the Time Machine backup?  Will that result in duplication?  Sorry, but I've no experience at all with Time Machine backups and don't know whether you can 'pick and choose' what to restore from the Time Machine using Migration Assistant.

  • How to Back-Up Mac through Recovery Mode?

    I'm not to good with computer terms or stuff like that, so please bear with me. Every time I start up my MacBook Pro, a loading bar comes up and then when it completes, it restarts, with the same thing, a endless cycle of loading bars. So I looked at quite a few threads but couldn't find a specific answer to my problem. I want to do a reinstall of new copy of Lion but back-up my data first (there is only 50 GB). I can start into Internet recovery mode. I did the whole "Verify Disk" in the Disk Utility and it said that "The disk needs to be repaired. Click Repair Disk". In which I click repair disk. But then it says "Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files".  All I have is a 500 GB Seagate External hard drive for Mac, no additional Mac or time machine to back up to. So is someone able to give me step by step on how to back-up my data in my specific situation? I tired to create a New Image of "Macintosh HD" but it says "unable to create "Macintosh HD.dmg". (Error -61)". Also, the Macintosh HD is dimmed (grayish) in the left, but I can still click on it. I don't know what that means. Is there also any way to move files in recovery mode through terminal, from the HD to my external hard drive. As a alternative back up?
    Please, any help would be awesome.

    In order to follow the guides below, you will need access to another Mac and a firewire cable.  Your hard drive is failing. If you make an Genuis Bar appointment at a local Apple Store, they will be able to perform this. If you choose the latter, make sure to bring an external hard drive to which your data can subsequently be transferred to once it has been recovered from the failing drive.

    My ipod touch went to recovery mode after I tried to reset its network settings. I tried to connect it to itunes but it does not want to connect because I have a passcode and my ipod touch wont let me enter it so I could unlock it. Can somebody help me please? Thanks so much!

  • HT3743 Unlocked 3G blocked in recovery mode

    I have unlocked my old 3G phone and have used a Tmobile sim card successfully for over a year, but now the phone won't work and is blocked in recovery mode after I responded to an Apple update messages.  Suggestions?
