How do I restart my iMac in single user mode?

It doesn't appear to recognize that I'm holding down command-S when it boots. I'm thinking maybe it's because the keyboard isn't wired to the computer. This is a 6-month-old iMac running 10.7.3.

Try using a keyboard that's usb connected to the computer. This might work because it'll be recognized as the computer starts up.

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

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?
Oracle 10g R2 on Windows Server.
Thank you,
Smith

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.

How to Restore from Time Machine in Single-user mode?

Hi there, I am trying to fix a Macbook Pro that has had its /private folder trashed and emptied. Obviously it won't boot unless you you boot in to Single User mode and I'm wondering if its possible to do a Time Machine restore from the terminal, I would need the 2nd more recent Time Machine image which is sitting on a Firewire HDD.
I was going to just see if I could find the orignal OSX install disk and just do a fresh install of the OS which I don't mind doing (since everything important is backed up in Dropbox), but I can't seem to find the CD anywhere nearby, so the Time Machine option would be much preferred.
Any help would be greatly appreciated.

Not sure if this is related enough, but I just wrestled trying to restore from time machine too, trying to reinstall 10.5.8 after putting a new HD in my MBP, 2006 vintage.
That took sooooo long to get back to where I was before swapping disks; what did the trick was ordering a free copy of Snow Leopard install disk (free due to Apple trying to push people from idisk to icloud) which was rushed FedEx (yay) and which allowed me to access Time Machine where my ancient original OSX install disk had not.
And all it took was 2 weeks of cursing!

HT1492 Does anyone knows how to change the keyboard layout in single user mode, please ?

Hello,
The question is in the title.
Thank you.

The only way you might do it is use one of the Unix editors to edit the plist file it gets the settings from once it boots in the GUI mode. 'vi' is present in all Macs, and you might have pico, nano, emacs, or ed depending on what was installed. The keyboard layout while in single user mode itself I think is generic to where the Mac was bought and what keyboard was ordered with it, when it came from the store. Since you posted in the 10.3 or earlier forum, chances are if this has changed, few people would know for certain. If you have a newer Mac, say 2006 or later, you should really post in the correct forum:

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?

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.

Start vm linux Guests in single-user mode

Hi -
I have OBIEE vm template installed and everything is OK, I forgot the roor password for this guest, (ovsroot) is not working I think I've changed it. One option is to start this guest in single-user mode, I tried but you can't see the console until the system is starting services which is a late phase to run linux single command on boot prompt. Please advice how can change my root password using single-user mode.
thanks in advance

Sorry, but I am not sure I am getting this right, where should I add 'single console=xvc0', if you mean the guest, as I mentioned in my post I don't know the root password and I can't logon. please kindly if you can add more detailed steps.When you boot your guest using xm create -c vm.cfg, it will immediately connect you to the console of the guest. That will show you the GRUB boot menu. You then need to edit the kernel boot line exactly the same way you would a physical server. In order to boot into single-user mode, you need to add the parameter single to the boot line. Along with that parameter, you also need console=xvc0 so that the guest uses the connected console to show you the boot process and allows you access to the single-user shell. If you do not use this parameter, you'll need to determine the VNC port used by the guest and used VNC to connect to the console instead.

How to restart computers in single user mode?

I 'd like to use ARD to send a command to reboot target computers in Single User mode (and then run line of command).

have you considered just using safeboot? safeboot dose many of the same things applejack dose, and it's built into the mac os x.
Safeboot using ARD:
You can start a safeboot by send unix command, as root, command:
nvram boot-args="-x -v"
send command reboot computer
After the reboot, you could then send unix command, as user root, command:
sudo nvram boot-args=""
send command reboot computer
NOTE: some features do not work while the computer is in safeboot, so it's a good idea to have the computer plugged in by ethernet, because most macs still work over ethernet in safeboot.
Or you could just tell the user to reboot the computer holding the shift key, and when they get to the login window with the words "safeboot" to reboot the computer again.
FYI: in the past i've ran safeboot, and watching the output, I could see it repaired the disk and permistions. soo if I had a disk that needed repairing, you could in thory try safeboot to fix the issue. The computer already runs a RAM test every time you power on the computer.

IMac 7,1 boot only in single user mode

Hi all
I've a colleague with the following problem... his iMac 20'' (iMac7,1) is able to boot ONLY in safe/single user mode (with shift key pressed during boot).
If he tries to boot normally, after the usual Apple logo screen he gets a blank (light grey) screen. No finder, no login screen.
We've tried this procedures:
- SMB reset
- PRAM cleared
- OS Reinstall (we've tried from Lion to Mavericks... actually there's 10.7.5 installed)... note that ALL installation procedure has completed successfully.
- tested the 1 RAM module installed (seems to be OK)
- tested the HD (no problems found)
Despite all these attempts, this iMac is booting well only if we press SHIFT during startup. All programs run well, wifi is working and online update too. If we reboot leaving it to restart normally (no key pressed) it shows Apple Logo for 1 minutes, then (after a black reset of the screen) seems to crash/stuck into an empty grey screen.
Is possible to identify which driver/kext is causing this problem? It can be an hardware problem? How we can fix it?
Thank you!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

IMac G5 only starts up in Single-User Mode

I am using an iMac G5 with the lastest version of Tiger.
I was trying to make a my.cnf file for MySQL for it to start logging queries, however was having some trouble doing so. After restarting MySQL a few times it would not start up any more, so I tried restarting the computer.
After doing this Personal Web Sharing (httpd) would say that it was running although would not serve pages. So I tried restarting httpd which got it running properly, however I still had the same problem with MySQL, where it would not start running (the Preference pane would not respond when clicking "Start".)
So I tried restarting again. Now my iMac will only boot into single-user mode.
I read somewhere about modifying the boot-args, however have not had a chance to try it yet. I don't see why this would do anything however, as I'm not sure why that would have been changed in the first place?
Has anyone heard of a similar instance, which is possibly related to MySQL?
Thank you in advance for any help.

G5 iMac Mac OS X (10.4.7)

I solved this. I was able to boot up in verbose mode and note that a certain missing file '/etc/hostconfig' was mysteriously missing and causing an error at the boot-up. I was able to boot this mac up in Target Disk mode and copy the file into the /etc/ directory from a backup through another Mac and now it's working fine, thank G-d!

How to eject DVD in single user mode

Hi All,
When starting my iMac, I get a white screen, the apple logo and the spinning wheel. After a while it goes away and I have just a white screen.
I've reset PRAM, to no avail (it did do something, the computer start up sound now occurs each restart).
I can't start-up on the Mac OS install DVD because I have a DVD in the computer already and I can't seem to eject it.
I can't get into Open Firmware mode to eject the disk there, I'm hoping someone can give me the command to eject the disc from Single-User mode.
Chris

Try the methods listed in this page:

The method for Terminal may also work in single-user mode.

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!

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.

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 restart my iMac in single user mode?
