  • How do I get networking in single user mode?

    My MBP won't boot OS X anymore (it tell's me I have to restart my pc). This happend after I redid my boot camp installation. Anyways disk utility/fsck won't repair the drive but I can still read the files...
    Now whenever I try safe boot or run sh /etc/rc the machine panics/restarts. However single user mode has an ftp client and I have enough storage on a networked ftp server. Question is how do I get ethernet going without running sh /etc/rc?

    Enter the following command into the Single User mode prompt:
    ifconfig en0 up
    Try using the FTP client after running the command. It assumes the connection used is the built-in Ethernet connection; use en1 for an AirPort connection or fw0 for a FireWire cable. The 0 is the number zero.

  • 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

    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!

  • How do change boot disk from single user mode?

    My G5 hangs when booting at the blue screen while "Loading printing services...". Attempting to boot into safe mode only hangs at the grey gear screen. It will, however, successfully boot into single user mode. I've run fsck but no change in bootability. I have another disk in the machine that has Tiger on it. How do I change the boot disk from the single user prompt?

    You can hold c and boot off the installer disk and select disk utility repair disk/permissions
    or you can hold option to boot off Mac OS X on another drive, like a clone and run Data Rescue to recvoer your files.
    It does sound bad, you can try going through these
    http://docs.info.apple.com/article.html?artnum=106464
    But I think you'll need a fresh install, hopefully you have been backing up/cloning to a external drive.

  • How format the hard disk in single-user mode

    Hi all, i would like to format the internal hard disk of my macbook pro 13'' through single-user mode. How can I do it, please?

    Ok, to do that you need to hold c and boot off the 10.6 installer disk and second screen in under the Utilities Menu is Disk Utility.
    You can then select the hard drive makers name (your "bare metal") and peform the wipe/format of the entire drive or a "partition" on that drive.
    In the picture below there is only one partition, the Mac HD. In the picture above there are two partitions which both would show up under the hard drive makers name and both or either partition can be wiped in Disk Utility.
    Use the Security Option to Zero your hard drive of all lingering data.
    When you Quit Disk utiltiy, your back in the installer and can quit or install OS X.
    Note: messing with Disk utility will erase all data on the drive, if there is something you need to recover better stop and ask!
    If you don't see your internal boot drive in Disk Utility, the drive is dead.

  • How to reset admin password in single user mode

    How do I reset and admin password in single user mode. All the posts I have read so far dont work. I tried adding a new admin password as posted on the forums by deleting setup so it will setup like it was first time setup but that didnt work . Any suggestions would be appreciated.
    The account now only has the standard user account as admin. Admin account I deleted in trying to fix this problem.

    1 - Does it boot into Leopard?
    2 - Does it have any important data on it that is not backed up elsewhere?
    It it boots into Leopard you could continue using it and hope that you find your Leopard install disks later or discover some other way to overcome the lost password.
    If it is fully backed up or has no important data on it you could install Tiger.

  • Scrolling in single user mode

    how can i scroll windows in single user mode?

    Hi, if we're talking about the Single User Mode, there is no Window at all, it's like the old dumb Terminals...
    But you can read a log to possibly see some stuff that was logged...
    tail   - Print the last few entries in a log (or other text file). Useful to find out what happened to get you into this mess.
    Examples:
    tail /var/log/system.log
    print the last screenful of entries from the main system log.
    tail -1000 /var/log/system.log | more
    print the last 1000 entries from the main system log, using more to display them one screenful at a time (remember: in single-user mode, there's no way to scroll back like you can in a terminal window).

  • Single user mode: Argument List is too long, PLEASE HELP

    Hey guys,
    I recently posted a topic asking if any1 knew how to delete all png files on the desktop,
    Nt many people replied,
    But anyway, I did some research and now I know how to do it,
    but in single user mode (cmd + S),
    When I typed in rm *.png
    While I ws on the desktop in single user mode,
    It came up saying Argument list too long,
    Does any1 know how to fix this,
    Plz reply ASAP,
    &amp; if possible addme on Skype mark.davidson19, it wld b extremely helpful

    If there are too many files expanded via the *.png wildcard, then the argument list length maximum can be exceeded.  The last time I checked, Mac OS X had a 256K line length limitation. (AIX was 1M, Linux 128K, Solaris 1M, Windows 8K (Cygwin env) - your mileage may vary with each operating system release).
    If you have too many files to expand on the command line, then you can delete them in batches.  There are several ways to do this
    cd ~/Desktop
    rm [a-m]*.png
    rm [n-z]*.png
    rm [A-M]*.png
    rm [N-Z]*.png
    Or finer increments.
    You could use something like
    find ~/Desktop  '*.png' -print0 -depth 1 | xargs -0 rm
    And you can also use
    find ~/Desktop '*.png' -depth 1 -delete
    This being a Unix environment, there are most likely a dozen additional ways to delete all the .png files and avoid command line length limits.
    As MrHoffman says, using rm and wildcards is a very dangerous thing to do unless you really REALLY know what you are doing.  If not, I strongly suggest having a recent full backup handy.  I actually suggest a backup regardless of how good you are in the Unix environment (I have multiple via different backup utilities preformed on a very regular basis;  years of experience has taught me you cannot be too careful with your data - it is worth far more than the cost of backup equipment).

  • Starting up networking in Single User Mode

    I have been searching the web for how to start up networking in Single User Mode.
    For Leopard 10.5 I found this:
    http://bitaddict.blogspot.com/2009/06/networking-in-mac-osx-single-user-mode.htm l
    +*III Start the network*+
    +The following commands have been working on Mac OSX 10.5 (Leopard). If you have another version of OSX they might be different.+
    +In order to get the network working we need to start the following four services+
    +% launchctl load /System/Library/LaunchDaemons/com.apple.kextd.plist+
    +% launchctl load /System/Library/LaunchDaemons/com.apple.notifyd.plist+
    +% launchctl load /System/Library/LaunchDaemons/com.apple.configd.plist+
    +% launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist+
    For Tiger 10.4, I found this:
    http://www.westwind.com/reference/OS-X/commandline/single-user.html
    +*Starting daemons under 10.4:*+
    +sh /etc/rc - Under version 10.4, the normal startup script can be run by hand, and it'll do the necessary work of getting the system (mostly) up and running, but not exit single-user mode or start the GUI.+
    10.5 seems awfully complicated. Isn't there a simpler way to start up networking in Single User Mode in 10.5, like for 10.4 or even like how it was for 10.2?

    sh /etc/rc
    Should you have some problems with your Tiger machine, running this script will likely reveal them.
    As for leopard, you could write a script to run these commands.
    You do know that the up arrow does a command retrieval so that you can backspace and change the last portion of the command.
    There is also the history command.
    mac $ history

  • How do i repair my hard drive in single user mode when disk is full?

    Hi there Apple Community!
    I have an old Macbook Pro 17" with an upgraded 500GB harddrive and 4GB memory. I'm running Mac OSX Lion.
    Was hoping you could help me out.  THis is the situation:
    Long story short I spilt wine on my macbook and the screen went a bit blobby. Switched it off for a few days, removed the battery etc. etc. Opened it up cleaned out as much of the wine as possible, but unfortunately some of it came in behind the LCD, so now the screen has a nice red stain.  Obviously I'm not going to try to clean that out of the LCD. 
    My Macbook Pro still worked for a few days after that, but then my harddrive gave up.  I booted in the Recovery HD menu, verified the drive and I got the error "Keys out of order - This disk needs to be repaired, click Repair Disk." I attempted to repair the disk but got the error "Keys out of order - Disk Full Error - The volume could not be repaired".
    Unfortnately of this 500GB I only have about 7GB free on it, as I have a huge iPhoto and iTunes library. I did make a TIme Machine backup of my user directory, but not the system files.  I don't really want to do a clean install because:
    1) I'm paranoid that there's something I did not fully back up
    2) I don't want to have to download the whole Mac OSX Lion again. I should have made a USB bootable backup when I had the chance.  I don't have access to a broadband connection.
    What I feel are my viable options, are as follows:
    1) I did buy a replacement internal 500GB harddrive, so I can probably try to make an image of the hard drive to this new drive, but not sure how. I believe it's through the Disk Utility with the "New Image" option but not sure how to go from there.
    2) Start up in Single User Mode and delete some unnecessary files and re-attempt to run the fschk -fy utility again (I tried this earlier and got the same Disk Full Error).  - the problem with this is, I'm not familiar with the command line and have no clue how to delete files.  I don't know my way around Unix.
    3) I can also probably attempt to make a Ghost Image or Acronis Image of the failed drive to this new drive, but not sure if Norton Ghost or Acronis True Image will be able to read this HFS drive - I believe it's possible as it's a simple hard drive clone. 
    If you can guide me in the best option - probably there is a better solution than my proposed ones above, I appreciate any feedback and comments you might have!

    hi Baltwo,
    So I ended up copying my user folder to another harddrive. I managed to download the whole osx lion again, reinstalled, and recovered my home folder using this discussion:
    http://support.apple.com/kb/HT1428
    I have managed to get all my files back. My iTunes library works fine, but my iPhoto library when I open it, get the following error:
    iPhoto cannot be opened because of a problem.
    Here's the error log

    I've done an Apple Software Update but it didn't find an update for iPhoto.
    One thing to note is, this library was originally created on iLife 08, upgraded to '09 and it stayed on that version. It hasn't een upgraded to iLife '11.  It worked fine on my previous install of OSX Lion.  How do I recover the library without upgrading to '11 ?

  • How to mount USB & CDROM drives from single user mode - Solaris boot disk?

    Hi All,
    I need to carry out ufsrestore on a single newly replaced system disk (no redundancy / mirroring) from either USB or CDROM drives from the following steps:
    ( i ) GRUB => e, e, cdrom –s, Enter, b (boot from Solaris 10 x86 media).
    ( ii ) Choose menu 1 for Install Solaris Interactive Mode to reach single user mode.Below are the commands that I have tried in single user mode without success:
    mount –r –F pcfs /dev/dsk/c1t0d0p0 /cdrom (after unmount Solaris CD)
      mount: /dev/dsk/c1t0d0p0 is not a DOS filesystem.
    svcadm –v enable smserver
      svcadm: Pattern ‘smserver’ doesn’t match any instances
    svcadm enable autofs
      svcadm: Pattern ‘autofs’ doesn’t match any instances
    devfsadm
      devfsadm: mkdir failed for /dev 0s1ed: Read-only file system
    mkdir /mnt
      mkdir: Failed to make directory “/mnt”; Read-only file systemPart of the problem is due to the current READ ONLY filesystems which does not allow the creation of mount point such as /mnt.
    I have been able to create both / root (/dev/dsk/c1t0d0s0) and /export/home (/dev/dsk/c1t0d0s0) filesystems with newfs that are awaiting for restore using ufsrestore.
    The only option I am left with is to attach a secondary disk to install Solaris 10 on either of them before bring the system to multi-user mode so that service such as volmgt, autofs, volfs are available to access USB & CDROM drives.
    Any suggestion on how to resolve this issue?
    Many thanks,
    Jack

    Hi JKGN,
    Is the directory a located under the root filesystem. ie /a? Are there any other mount point for say USB drive as well? I am not in a position to try it out right now but will get back
    to you soon on whether /a exist or not.
    Btw, the last thing I managed to do on this system at the time was added a secondary 1TB internal disk with the intention to restore both / and /export/home data onto this disk while
    making use of all the disk device management services such as the following services only available in a fully installed Solaris system (both single & multi-user modes) installed on the
    primary disk:
    # svcs smserver

    As a result, I am left with no option but the need to rebuild this system with only a single primary disk while in single user mode. However, the single user mode that I am in is the
    one from Solaris installation disk with restrictive (_cannot create folder for mount point or running disk management utilities_) capability such as those services just covered, compared to one from a completed Solaris installation system with full access to all filesystems and utilities / commands in general.
    I would very much value your assistance on how to mount both CD & USB in this restrictive limited Read Only OS (assume that it is running from memory) in order to get complete access to
    the blank primary disk so that full restore with ufsrestore could take place.
    Thanks in advance,
    Jack

  • To mount a CD-ROM in Single User Mode.  How?

    Thank you for reading my question. 
    I need to run single user mode on my iMac because of a disk problem.  I would like to be able to mount the cd drive while I am in single user mode.  I would also like to be able to mount usb hard drives with confidence, so that I can copy off files from the internal hard drive. 
    I am in single user mode, which I get to by holding down Command-S on startup.  I can look at the disks that are attached to my computer by executing
    ls -l /dev/disk*
    However this appears to be adding disks.  I started with /dev/disk2 and /dev/disk2s1 etc which I understand are partitions on that external drive.  Now when I list /dev/disk* I have /dev/disk3 and a couple of partitions on those devs.  Is that normal?  Have I not unmounted disks properly?
    I have been using a directory that already exists as the mount point for my usb drives using
    mount -t hfs /dev/disk1 /cores
    which worked fine.  Alas the disk I mounted on that directory was too small.  Now I can't mount a disk on there.  Do I need to unmount or fix up that assignment? 
    If I were to create a directory in /Volumes is that advisable?  How do I make the root directory readable is that by using 'mount -uw'? 
    Thank you.  Please if you answer my question, try to be clear on what commands to use and why.  Bear in mind that other people will read this, and no one on the web seems able to write suggestions very clearly.  Maybe we can be the first!  If I have not been clear, please feel free to ask for clarification.  i am not a total unix newbie.  Rather in the 20 years since I was a sysadmin, my memory has faded. 
    Pete

    I think you need to post this in a different forum.  I think the Developer Forums would be the right choice.
    In any event from the little Unix I know you can't mount a removable device until it's connected which means you need to put a CD/DVD into the optical drive.  At that point if you enter 'df' you should see the device if it is mounted automatically (which I believe it does.)
    In single-user mode the entire drive is readable and all files accessible.  You are the 'root' user.  In order to put the system into write mode you must enter 'mount -uw /'.  Note the '/' at the end of the comnmand line.  That makes the entire system writeable.
    You do not need to create a directory in /Volumes.  When the CD/DVD is recognized an entry in /Volumes will appear unless the disc is unformatted.
    Now take some of the above with a grain of salt.  I'm certainly no Unix expert.

    The impact is none of the users will be able to connect to the database/application (except for the sys user which can connect to the database). Usually, you would need to put the database in restricted mode when doing upgrade/migrate (i.e. you do not want to have active user sessions in the database during that time).
    Thanks,
    HusseinHi
    i want to mean:
    ALTER SYSTEM QUIESCE RESTRICTEDThe ALTER SYSTEM QUIESCE RESTRICTED statement may wait a long time for active sessions to become inactive. You can determine the sessions that are blocking the quiesce operation by querying the V$BLOCKING_QUIESCE view. This view returns only a single column: SID (Session ID). You can join it with V$SESSION to get more information about the session, as shown in the following example:
    select bl.sid, user, osuser, type, program
    from v$blocking_quiesce bl, v$session se
    where bl.sid = se.sid;I suspect all apps user can.t login to db?

  • How do I reset Tiger Mac OS X 10.4 admin password by using single-user mode

    bought a used PowerBook G4 on Ebay. The administrator's password was locked. The Powerbook still can run to the normal screen. However, I am unable to update and install software without a password.
    I don't have the original install CD either the second mac for firmware reset. So I wonder if anyone knows how to reset the password by using single user mode or any other methods to do so?
    Any input will be greatly appreciate it. Thanks.
    Powerbook G4   Mac OS X (10.4)  

    This morning we lost power and my iMac G5 (10.4) system got messed up. Specifically, when it restarted, all text in all Finder and application menus were blank (e.g. Click the Apple menu and a long empty white box stretching to the bottom of the screen would appear with no text. The whole box turns blue when you click in it. Ditto for all other finder menus and dialog boxes. Event the User menu was empty. The Disk Utility application shows only icons and empty buttons--no text.)
    Restarting in Safe Mode was no better.
    I then connected the G5 as a target disk to my iMac G4, and ran the OS X install that came with the G5 (10.3.2). It told me that in order to install an earlier OS X version, I must select certain options: I checked "Archive and Install" and "Preserve Users and Network Settings" (I have 4 accounts set up in addition to my onw admin account) and proceeded with the installation.
    At the end of installation, the G4 started (G5 is still in target disk mode) with the G5 as the startup disk. It presented the User Login screen (although it normally does auto-login on my account) but the password for each of the 5 accounts was rejected. The original hints still appear, but it seems that all passwords have been changed.
    I then tried the G5 on its own (not as a Target disk) but when it starts up the grey Apple turns into a grey "do not enter" (circle/slash) icon and goes no further.
    Can you suggest what I should do now?

  • How to restrict the all access ? Single user mode....

    I am doing export/import of schema objects from Windows to Oracle. How to make sure when I do the export in the migration database no one else is modifying the data. Is there any single user mode so that I can be sure of only one connection while exporting?

    Thank you,

    Perhaps you are not familiar with the concept of multi-version read consistency.
    No one can see that which is not committed and reads can never be blocked.
    If you want a system where no one can see things kill their sessions and do a STARTUP RESTRICT.
