Can not startup in single-user mode

I can not get my MacBook to startup in single-user mode. I am holding Command-S at startup but it starts up normally.
I also tried starting up in verbose mode by holding Command-V. That didn't work either. I then used the Terminal command to make it start up every time in verbise mode. That worked but I don't really want it doing it every time.
So then I thought it was because I have a firmware password set. I then started up holding the Option key so I can enter the password. The password field popped up as it should, I entered the password, then held down the Command-S keys to startup in single-user mode. No dice.
Can anyone tell me why I can not get single-user or verbose startup modes working?

Because entering the password into the Startup Manager doesn't disable it or any of the other functions it provides. You need to use the Terminal method or take the password off.

  • Can't start in single user mode, trying to fix blue screen startup

    Trying to fix my blue screen startup and I'm on the step to fix the Network Preferences and I'm suppoed to go into single user mode. It starts but then locks up. last line is: localhost:\ root# Anyone have an idea?

    Hi David.
    Sorry we haven't received any response yet. getting used to the new forum is occupying a lot of peoples time at present I fear. I've yelled a bit louder this time!
    In the mean time, have you already tried starting up in SAFE mode, rather than SU? http://docs.info.apple.com/article.html?artnum=107393 and following the other processes identified in http://docs.info.apple.com/article.html?artnum=106464
    If you have access to another firewire equipt Mac then you could also use Target disk mode (connect the two together with a firewire cable, then start up your own computer while holding down the t key. ) Your own HD would then appear on the desktop of the other computer as another HD, and you can then proceed to remove or shift the same .plist files (on your own HD) identified in point 4 or 5 of http://docs.info.apple.com/article.html?artnum=106464

  • Freezing with blue screen & can't boot from single user mode or disk

    My keyboard is wired and plugged directly into my Intel iMac running OSX 10.5.8. I do not have the Leopard disks, but I do have the Tiger disks. I was trying to boot in single-user mode so that I could run AppleJack to try to fix another issue I'm having--I get the light blue startup screen flashed at me several times daily for the past week or so. When the blue screen flashes, it totally freezes my computer (obviously) and lasts from 1-10 seconds. I can't find anything that is triggering it. I haven't installed anything new that I'm aware of, and it happens whether the computer has previously been slept or not. I'm also not using an external display / additional monitor.
    Also, for anyone who is nice enough to answer, please explain everything--I'm not an expert user.

    Well since it is so time consuming and a security risk to turn off FileVault, I was hoping to hear from someone with more experience if this was the solution, or just something to "try"? Are you speaking from experience or just making a suggestion, leroydouglas? Thanks.

  • Why can't I enter single user mode on my Mac Mini for an admin password reset?

    Hi,
    I recently created a new user account for my mac and deleted the old one, not realising that this was the only account with admin priveleges. As such, I no longer have access to administrator priveleges, and cannot grant them to my new user account.
    I have tried to boot in single user mode and recovery mode but neither command results in any reaction on the part of my computer.
    This thread follows on from a previous, unrelated disscussion:
    BDAqua: If you hold alt key at bootup do you see a lock in the middle?
    Yenots: No...what does this mean?
    BDAqua: If it did, it would mean Firmware Password Protection was enabled, which prevents booting in other modes, so that's not the problem, are you using a wired Mac KB, or Windows KB?
    Yenots: I'm using an 'Apple Keyboard with Numeric Keypad' [ http://store.apple.com/uk/product/MB110B/B/apple-keyboard-with-numeric-keypad-br itish ]
    If you find me here BDAqua, hit me with your knowledge!
    Any other contributions are welcome and, now we're under the right heading, will hopefully help other users who have encountered this problem.
    Thanks, Cristo

    Hi,
    Thanks for the link to MacPilot, and the sexy screenshot. I found an archived version for 10.4 on the koingosw website. That solves getting into single user/safe mode. Though I'd be interested to see whether sudo nvram boot-args="-s" will result in single user boot.
    As for creating administrator priveleges for my new user account, I've found a method which looks good:
         \single user mode\
         cmd-s
         \mount drive\
         mount -uw
         \open 'directory access'\
         lauchctl load /System/Library/LaunchDaemons/com.apple.opendirectory.plist
         \list users\
         ls /Users
         \change password\
         dscl . passwd /Users/<username> <password>
    I think that this method intends that if I change the root users password I'll be changing the administrator password  (as root is the only user with administrator priveleges), and subsequently be able to change my new user accounts priveleges using 'netinfomanager'. But I'm not 100%. Could you give me your opinion on this?
    Furthermore, three keys 'L' 'O' and '(' aren't working on my keyboard, which means I can't try this until I find an intact keyboard to borrow. I was thinking maybe a mod version of the above instructions would work in terminal using sudo, so I could use the keyboard viewer to type the missing characters. If you have any ideas on constructing such a mod I would be interested to hear them.
    Otherwise, Thank You for your help BDAqua! And enjoy your summer wherever you are.

  • Macbook Pro 2.2 GHz Kernel Panic on Startup, except single user mode

    No matter what I have tried, my Macbook Pro will only boot in single user mode. It won't start from my backup drive, or the OS X disc as it always gets a kernel panic after about 15 sec. I am not sure if there is some troubleshooting I can do from the command line.
    I tried running system profiler to see if the NVidia card is at fault, but system profiler doesn't finish it's output.
    I have run a disc scan and it says the hard drive is ok.
    Any help would be much appreciated - a local Apple Auth Service Tech couldn't help me.

    So I just ran Apple Hardware Test and first two attempts get code:
    4SNS/1/40000000: TB0T
    Anybody? Logic Board?
    And on a third attempt:

  • Can't boot in Single User Mode or zap PRAM on iMac G5

    I want to boot into Single User Mode in order to run Applejack to "clean" the system before applying Apple's latest security patches. So I hold down Cmd-S at start-up, but it has no effect; the computer boots normally into the Tiger GUI. Thinking that zapping the PRAM might help, I restarted while holding down Cmd-Opt-P-R. Same result: normal startup with no zap. I tried resetting the power management circuit by unplugging the iMac and depressing the power button. No effect.
    Apart from the inability to do special boots, the system seems to be running just fine. Any ideas?

    Ben F-
    Not guessing yet. You did not provide what steps you have taken thus far and now I know.
    I am thinking then that you have somehow set up firmware password protection.
    At least the things that you describe are disabled if a password is set.

  • Can't type in single user mode

    Hi,
    I am trying to fix a MacBook Air's hard drive and attempted to boot from single user mode to run fsck. However, when I get into single user mode I can't type a thing. No buttons on the keyboard work. I shut it down and tried doing it again but the same issue occurs. I tried again, this time connecting an Apple USB keyboard and it still wouldn't type. I booted from an external hard drive that had OS X on it and both the inbuilt and external USB keyboards worked absolutely fine.
    Does anyone know why I would be having this issue and how to rectify it?
    Cheers.

    Reinstall Lion, Mountain Lion, or Mavericks without erasing 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.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.

  • Can you run a bash script on boot in single user mode

    Hey guys quick question.
    Is it possible to run a bash script on boot in single user mode.
    I can create a file and dump it on the root hd.
    Let's call it repair.
    I can then boot to single user mode and run it by typing /repair.
    But I want it to do it automatically.
    Every time I go into my machines that I clean for my job. I have to run sbin/fsck -fy
    Then I have to mount the drive and then remove all cache files, then reboot the machines.
    I would like to automate this by just holding command s and then moving to the next computer.
    There must be some sort of boot daemon somewhere.
    Please help.
    Sincerely,
    John

  • How to get to single user mode

    I aquired an old power mac G4 with an old account with 10.3.9 and an old administrator account.  It seems that procedures to remove the account start in Single user mode.  The computer won't start when holding down system - s.  The drive clicks a few times but the display goes to sleep from no video signal.  So How can I get to single user mode when the usual way don't work?

    The hard drive's directory may be dead, or it may have last been booted into Mac OS 9.  IF you are lucky, they did install Mac OS X on it, and that can be determined either through an Option key boot, or through an X key boot on a wired (not wireless) USB Apple compatible keyboard.   X key booting will only work if the X operating system is on the same partition, whereas Option key boot will reveal the Startup Manager, where you select the drive and hit the right pointing arrow for the drive partition that has Mac OS X.   Note this will not work on an original PCI PowerMac G4.   You may also need to replace the PRAM battery, a 1/2 AA 3.6V battery from Radio Shack before any boot sequence will work.  Once it boots into Mac OS X, Single User Mode should work.

  • Single user mode, Lost Admin Account, and Disk Permissions

    Okay, so I have quite a few issues here. I will start from the beginning.
    About a week ago, I tried to install some updates and I could not get the Admin account to work. I went to the users profile and noticed my Admin account was not there. Did a quick search and found Apple's outline of how to fix this via the Operational DVD and the root user. Tried this and it would never work, because as soon as I restarted the computer or changed screens it switched back to a standard account.
    Next up, I went into the terminal to check the Admin User group. As it turns out it is not there. So I find a discussion on there that outlines how to rebuild this in single user mode and the Unix prompt. So, I print it off and try to restart in single user mode. After trying two different keyboards and a sum total of 8 to 10 times, I can't restart in single user mode to get to the Unix prompt.
    One last thing, last night I went into the Disk Utility on the start-up DVD. I wanted to check the Repair Permission log and I got the following:
    ACL found but not expected on "private/var/root/Library/Preferences"
    ACL found but not expected on "private/var/root/Library/"
    ACL found but not expected on "Network"
    Thoughts?
    Thanks for your help!
    tpp

    first, the ACL messages can be ignored. if you can't get to single user mode you can't fix your admin group. the only reasons that I know why you wouldn't be able to do that is
    1. a defective keyboard
    2. you have a firmware password set. have you? you'd have to turn it off before you can get to single user mode.
    lastly when you restart in single user mode make sure you press command+s right after you hear the chime. do not press it too early or too late. lastly, I'm not sure which instructions you've found to fix the admin group but I have them in this thread

  • Unable to start in single-user mode - HD dead?

    My MacBook Pro (Mac OS X) refused to start, it hung up on the loading screen where you see the apple and the spinning loading wheel. I found out how to fix this, I had to go into single-user mode and type "/sbin/fsck -fy" to repair/verify the disk (I was unable to do so from the Disk Utility via the Install Disc, the repair/verify buttons were just grayed out).
    Anyways, doing this from the command line (single-user mode) fixed the problem and I could boot into Mac OS X (there were more issuses after this point which forced me to do an "Archive and Install").
    ^ that happened a week ago. And happened again yesterday, hung up on the exact same point. So I boot up my Mac into single-user mode, and type in "/sbin/fsck -fy" to start the process. Different from last time, I got a lot of text this time. It also kept going for a longer while. After about 10 minutes, there was a couple of minutes where nothing happened. So I typed "/sbin/fsck -fy" again (as I'm supposed to do so until it says "** The volume (nameofvolume) appears to be OK"), and I got some more text, then nothing happened for a while.
    Inpatient as I am, I considered the process to be complete, and restarted my Mac by typing "exit".
    I think I ****** up my Mac OS X partition at this point. Because when I try to start my Mac now, it automaticly boots into Windows XP (my other partition). Also I cannot enter single-user mode or Verbose mode, the Mac just ignores and goes right into Windows XP.
    I've tried to boot from the Install Disc. When I run Disk Utility, the "HD"(name of Mac OS X partition) is grayed out. I can't do an Archive and Install because it cannot detect my main partition.
    An interesting thing though: When I have the Install Disc inserted, I can enter single-user mode (by holding cmd+s at startup). However, when I type /sbin/fsck -fy, it starts verifying the Install Disc rather than the HD.
    Also when I open My Computer in Windows XP, I can see the other partition (MacDrive). When I select it, I see:
    Free Space: 219GB
    Total Size: 168GB
    This indicates that my HD is dead/erased, and that my last three months of work is gone. This just because I'm impatient, and didn't wait for the fsck process to complete.
    What is the next step? How can I get into single-user mode so that I can verify/repair my disc?

    On the point of contacting the folks at Alsoft, I have found that they seem to be unobtainable on www.alsoft.com at present.
    I wanted to get in touch as I had a small problem with Diskwarrior on updating to 10.5.5 from 10.5.4 ,
    Disk permissions ends with an error code.
    I wonder if there were so many queries re this that they are unobtainable?
    I run 3 machines from a wireless router, an iMac, an HP laptop with XP and a totally obsolete Dell into which i have squeezed W2000, with a resultant mix of browsers but no contact with the folks at Alsoft.
    Am I in a minority of one here?

  • Bazzar Behavour? single user mode

    If I boot my G5 into Single User mode, the fans will slowly pick up speed and seem to go on getting faster and fastr. On exiting S/U mode and mounting the full desktop the fans will return to normal.- it's only in s-u mode that I have this problem....
    Is there a daemon or other which checks and controls these fans,- and is it not working in single user mode? any diagnostic tools I should use to check temps and fan speeds?
    much love,
    Alex.

    The fans are software controlled, and the software which controls them is not active in Single User mode; in this case, the fans will go as fast as they can.

  • I changed my wheel group properties to no access at top disk level.  I messed up, how can I change back in single user mode "command s" as I am now in Thailand and not able to access startup disks?

    I messed up, I changed my "Wheel group" properties to No Access ( or something other than the default) at the top level of my startup disk "Macintosh HD".   Now my computer won't start up, I just get the spinning wheel of death.    I also am in Thailand right now, so I cannot go to a Genius at an apple store, nor do I have startup disks available.
    So I was hoping there was a way to change back the properties of my disk (Volume) in single user mode (via Command +s) during startup, i.e. can I do a chmod command on the Macintosh HD listing under the Volume Directory.    Or where do i fix this?   Is it fixable without startup disks, etc...
    THANKS FOR ANY HELP!!!!
    If you could also please let me know you have an answer, I WOULD REALLY APPRECIATE IT!!! 
    thanks so much

    <Edited by Host>

    Thomas,
    Thanks for the info on command-R, didn't know about that!!!
    Yes I changed the sharing "Wheel Group" permissions on my hard drive via Get Info.    But that's all I did.    And then most of the apps wouldn't respond with anything.    So not knowing I did something stupid, I decided to re-boot, and then nothing but the Wheel of Death at startup.
    I was trying to limit access to my computer on this network, changed my public folder settings, and then I thought why not the whole hard drive, but at that time I had no idea what the "Wheel Group" was... so I shouldn't have touched it, BUT IT DID ...... argggggg....
    I managed to go to an internet cafe & research the problem yesterday.    I used the command +s single mode to get in, and then did the necessary steps to mount the drive so I could make changes.   I basically did this:
    Boot into single-user mode (boot while holding down CMD-S)
    Follow the on-screen instructions to mount the file system as read-write (a fsck command followed by a mount command)
    Type the following: "chmod o+r /" followed by "chmod o+x /"
    Type "exit" to leave single user mode and complete the boot sequence.
    I found it at this link http://forums.macrumors.com/showthread.php?t=416180
    It worked... thank God!!!   Well so far so good.   
    I was going to try my own fix by chmod on the Hard drive listed under Volumes directory, but that doesn't seem to match the info under Get Info Window.    So I just used the fix above.    I probably should now go and do "Disk Utility - repair permissions", however I am a little gun shy right now, so I will probably wait until I am back in the States so I can go to an Apple store if it messes up.   Right now I'm following the "if it ain't broke, don't fix it" MOTTO...
    So Thomas I just wanted to say THANKS for replying so quickly, and I really appreciate your help!!!
    (yes I know I shouldn't have used my email addresses, but I WAS DESPERATE, but that's still no excuse)
    Hopefully maybe this thread will help someone else out in the future....
    Okay, thanks again!
