How to disable daemon in overrides.plist in single user mode?

I can't boot my mac mini server so I tried booting verbose to see where the problem is. The error message that I get is:
(com.apple.mDNSResponder[31]):posix_spawn("b/usr/sbin/mDNSResponderb",...): No such file or directory.
I know that the characters b at the beginning and end don't belong there but it's difficult to see where they come from. I know there is an overrides.plist file in /private/var/db/launch.db where I can try to disable mDNSResponder which probably let me boot normally but I can't seem to get write access to the file.
I tried /sbin/mount -uw / to mount the root read/write access. Also /sbin/fsck -fy to check the harddrive. fsck -fy makes note that he can't find any problems. Even if I try to make a file in the root directory after doing /sbin/mount -uw / I don't get write permissions with vi.
How can I temporary disable mDNSResponder or better yet fix the problem of directing to the right path?

After a reboot I used /sbin/mount -uw / to get write permissions. I went to the location of the mDNSResponder.plist to convert the binary plist into an xml one. With vi I noticed that there were some control characters included in mDNSResponder.plist which I only could see when converting the file into xml format. I removed the unnecessary control characters in the file. Saved the file and did a reboot.

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:

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 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.

Disable file service in single user mode?

After a failed (with an error) attempt to install the latest security update, the iMac won't get past 'waiting for apple file service' during boot. I presume the botched install left something bad, so I'd just like to get it booted so I can retry the install to see if that fixes it.
Safe startup doesn't work - it just reboots part way through.
So I'm trying to figure out how to disable the service altogether, from single-user mode.
Does anyone know what file(s) I need to modify, or what 'defaults' incantations I need to do, to disable it?
iMac G3, 600MHz Mac OS X (10.3.9)

I managed to disable it - moved the AppleShare folder out of /System/Library/StartupItems - but it just hung on some other service.
The CD/DVD drive is toast in this thing, so I can't boot from the O/S disks either. Target disk mode doesn't work either, even though it is supposed to for this model.
I'm looking into netboot now.

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
STATE          STIME    FMRI
online         Jun_08   svc:/network/rpc/smserver:default
# svcs autofs

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

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 can I mount a CD Drive in Single User?

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.

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.

How do I mount an external Firewire HD when booting into single user mode?

Hi,
How can I mount an external Firewire Harddisk from the Darwin Console, once I have booted into single user mode?
I'm trying to make a backup of all my files and then re-install my iMac G5 since it doesn't start the GUI anymore and I haven't gotten any responses to my question here: http://discussions.apple.com/thread.jspa?threadID=1104762&tstart=0
Thanks,
Torsten

ok, I executed the following commands:
/sbin/fsck -fy
/usr/libexec/registermach_bootstrapservers /etc/mach_init.d
autodiskmount
There were two messages:
UniNEnet: Ethernet address 00:14:51:32:19:b8
and
Aug 29 20:55:29 launchd: server 2e3b in bootstrap 1103 uid 0: "/usr/sbin/lookupd"[16]: exited abnormally: Hangup
I don't know whether this has anything to do with the commands I entered.
And since I don't know what the volume name for the external Firewire HD is, I typed
ls -l /Volumes
but the only volume that is being listed there is my iMac's internal HD.
What should I do next?
Thx!

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.

Stuck while booting in single user mode. How to go back?

Guys. I'd appreciate your advice very much - this concerns my main system.
MacBook 3,1 with OSX 10.5.? (latest)
Did: activate single user boot in Onyx; reboot
Problem: stuck at boot (apple logo & spinning wheel on gray background for 2hours+). Persistent across reboots.
No different results for this key combinations: cmd-opt-p-r, power button for 5 sec whilst without battery/cable, cmd-s, C (possibly not recognized due to firmware password) Power button held down from switch-on moment makes the light flash a few times, produces a beep but no improvement.
Interestingly pressing alt lets me choose the os (HD or Leopard install disc) but gets stuck the same way regardless. It boots into Ubuntu tho.
I have a TIme Machine disk that I can restore from, and can read from the internal Leopard HD while in Ubuntu.
So, please: how do I get it to boot? I'd set the nvram bootargs="" but from where...

Sorry, don't know how you'd recover from the apparent limbo you're in, but this would agree with the explanation you already hit upon.

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).

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:

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?
