Single user mode using from laptop

Hi,
I need to booting off the CDRom Solaris to rebuilding the server. But unfortunately, I am connect the laptop into the Sunfire V240 and I do not know how to make it boot in cdroom, since the laptop doesn't have a "Stop" key as Unix keyboard. Can you tell me how to make the system stop and give me an ok prompt????
Thanks,
HS

Single user mode . using tail -f (command not found)

Have an empty computer with no systems disk as the installation CD start up will not go past the grey screen with the rotating logo before the panic crash page comes up and tells me to restart the computer.
Trying to boot into single user mode and then use the command tail -f to see contents of some of the logs... BUT I get the reply tail command not found ????

If the hard drive is empty, then you can only boot from the CD. Regardless of whether or not it has "tail," it won't do you any good. There are no logs.

Powerbook -can't start up in single user mode or from CD-why?

My daughter was gifted a Powerbook (15"). I've upgraded it to 10.5.8. It has enough speed, (1.67 Ghz), 2 gigs RAM- but it is a sticky little machine- it freezes a lot. Froze twice during the upgrade, froze once during login, Froze once while trying to do a software update, froze once while trying to get into the system preferences. It freezes pretty consistently after 15-30 minutes or so, no matter what it's doing -if a program is running or not. I tried downloading AppleJack to run a diagnostic. That requires starting up from single user mode. I tried to do that , but the machine just opens to the login screen. I also tried running TechTool from the CD, and the machine wouldn't start up from CD either. What should I try next?

Try this one for some information.

Starting up in single-user mode problem

I'm trying to start up in single user mode using the Apple article. I ran fsck and everything checked out fine but when I type /sbin/mount -uw / I just get another prompt(#). I want to restore defaults because the users pane is blank. Iv'e tried trashing prefs,ect with no change. I'm sure i'm typing it in correctly. Any suggestions wil be appreciated.
iMac G5 1.8 17 Mac OS X (10.4.3)

I'm working with an iBook 600 OSX 10.4.3 that had a problem with a dialog box constantly coming up asking for the keychain password which had no password and you could just cancel out of it. I deleted some keychain user info and that's when the accounts pane became an empty window. So I'm going to use the Terminal to restore from defaults. I'm assuming that I won't loose any data doing this. It looks like my only option other than a wipe of the hard drive.

Keyboard completely unresponsive in single user mode

Since upgrading to v10.5.1 I have been unable to get both my Apple USB and Apple Bluetooth keyboards to work in single user mode. I can get into single user mode using the command-s keys but once there the keyboard dies. This is the only time the keyboard fails. I have no other USB device attatched. I am using the white (non-aluminum) Apple keyboards. I'm curious to see if anyone else has this issue.

It appears to have been a Bluetooth only issue. I got the USB keyboard to work in single user mode. However I had to first turn off Bluetooth before rebooting into single user mode. Originally I kept Bluetooth on before rebooting using my USB keyboard. This for some reason prevented the USB keyboard from functioning in single user mode. When I have some time I'll further troubleshoot the Bluetooth keyboard issue and report back.

Booting in Single User Mode

Hello All,
Just want to prepare ahead of time for possible server-down cases where a drive fails etc. What I want to do is find out a bit more about how the boot sequence is completed.
If for example the primary boot partition was to become corrupted, is there an easy way to boot from the cdrom and enter single-user mode? From there I could mount a drive, bring up the nic, and transfer files etc, as needed.
Normally with the bootprom on Sun hardware the stop-a then boot -s cdrom would work. What's the comparable command for Solaris 8 x86?
Thanks,
Mike

Mounting a dmg in single user mode

When ever I try to mount a .dmg in single user mode using "hdiutil mount /path/to/dmg" I get no errors but I can't actually access the mounted dmg, it never appears in /Volumes
My question is how do you access a mounted dmg is single user mode

I've run into similar difficulties. I don't know about 10.6, but in 10.5.8 the HDI driver appears to load fine. (You can check that with the kextstat utility.)
In fact, my 10.5 Install CD uses hdik to create RAM disks early in startup. However, the same calls to hdik fail when I try them in single-user mode.

Data back up from Single User Mode

Hello,
I have a problem with my 700 MHz iBook, dual USB, with OS X 10.3.9.
Unfortunately the OS doesn't start up because of "overlapped extent allocation" problem...
I would like to re-install the complete OS but before doing it, I would like to back up some directories.
Is it possible to save some data, by connecting an Ipod or some sort of external peripheral, from the Single User mode?
If yes, how can I do it?
Thank you in advance from your kind support.

Before giving up the ghost check out these:
http://docs.info.apple.com/article.html?artnum=25770.
Manually fix Overlapped Extent Allocation Errors without Disk Warrior
Overlapped overlapped extent allocation errors can be the bane of any Mac user's existence. Often, these errors go unnoticed until the problem becomes visible: your Mac might refuse to boot, crash unexpected, or worse, critical data might disappear from the Finder. Disk Utility can detect, but not fix overlapped extent allocation errors, and certain third-party utilities, such as Alsoft Diskwarrior, can fix them, but generally without reporting the consequences.
Overlapped extent allocation error occur when the file system thinks that two files are occupying the same area on the hard disk, hence overlapping on the same "inode," which is the structure which holds the location of the data blocks the file occupies, and also file permissions and flags.
Clearing the "overlapped" or "overallocated" extent allocation essentially means that you'll have to lose some data, because the only way to remove the overlap is to delete the file that's occupying the inode. So, if you suspect, or find out, that the guilty file is a critical system file that resides in one of the hidden system directories such as /etc /var /usr/ or visible system directories such as /System or /Library, and you don't want to reinstall the whole OS (which might not fix the overlapped extent allocation anyway), it's good to have another disk available to copy the files back to your original disk if necessary: a second bootable hard drive or a firewire drive connected to your Mac when you remove the misbehaving file. Just make sure that when you copy the file back to your boot disk that the permissions are correct, so it's best to use the "ditto" command, so that all sticky bits, flags, and permissions are preserved.
In case you didn't know, you don't have to boot from an install CD in order to check for overlapped extent allocations. All you need to do is restart your Mac, while holding down command + S to boot in "single-user mode."
At the command prompt that appears, type:
$ fsck -fy
If you have an overlapped extent allocation, you'll see:
"Overlapped Extent Allocation" (File 123456d)
No matter how many times you run fsck -fy, you'll never be rid of the error.
So, simply issue the following command:
find / -inum 123456 -print
Note the "d" was dropped, or any extra letter that appears after the inode number.
The find will return a file name that matches with the inode number, and the path to that file. If you remove the file then the fsck will not return this error next time you run it.
However, before you can delete the file(s) in single-user mode, you'll need to mount the file system. Type:
$ mount -uw /
When done, issue the "sync" command, and that will flush the write cache so that all pending writes are written from memory to the disk. Also, since most OS X 10.3 Macs use the HFS+ Journaled file system, it might be a good idea to disable the journal before booting into single-user mode by typing:
$ sudo diskutil disableJournal /
then re-enable it when done fixing the overlapped extents and rebooting normally:
$ sudo diskutil enableJournal /

If you own Disk Warrior then it should be able to repair a drive with overlapped extents.
There are two backup utilities included in Unix - psync and rsync. You will find them in the /usr/bin/ directory. For documentation simply enter: man psync or man rsync. In order to write data while in single-user mode you need to issue the command: /sbin/mount/ -uw / (Note: there is a "space" between the "uw" and the "/".) To mount an external drive you will need to provide the mountpoint for it in place of the "/", e.g., "/Volumes/volname") without the quotes.

IMac G5 won't boot in normal and safe mode, but will from single-user mode

Hello everyone,
I'm quite new here, so I try to do my best if you have a question.
Yesterday, someone nearby me had a iMac G5 (Powermac8,1), and he sayd, that the computer sometimes will boot, sometimes not.
I did test it, I thought it was running fine, but when I played some music in iTunes, it was stuck on 9 seconds, and crashed (with a kernel panic). The guy also sayd, that there was nothing important on the computer, so a clean install was fine.
Now, the problem is, that it will not boot in normal mode (without anything pressed on boot), also it won't in safe mode (shift-boot), but it will, when I enter single-user mode, mount the hard drive and exit from single-user mode so it will go futher on booting. Sometimes it will not, and immediately gives you a kernel panic in single-user mode, but it will 90 percent of the time.
Then you've got another problem: when it's running in the normal desktop from single-user mode, it'll be stuck after some time again. If I look into the Kernel Panic file created, most times it's because of Spotlight indexing, so I disabled that.
He also gave me the disks (Apple Hardware Test and Extra Applications, and iMac G5 Mac OS X Install Disks 1-3) that came with the Mac. He sayd that I could use them, but I think he didn't test out the SuperDrive, because when I insert a disk, it will try to read, but it will make 2 same sounds, and quits after 10 tries, when it will spit the cd out. Also normal (audio) disks.
Also, I must hurry with the commands for mounting and exiting in single-user mode, or it will just not boot.
In all cases, after 30-45 seconds from pressing the power button, the fan will start blowing at full speed, and it will stop after the exit command in Single-user mode. That's weird.
I can't do anything with the SuperDrive, I can't normally boot in Mac OS X except for Single-user mode (but I don't think he would like to do that every time the computer boots up), and I have very limited time when Mac OS X arrived on the desktop.
When booting in Verbose mode, it will be stuck on this:
AppleSMU::PMU vers = 0x000d004c, SPU vers = 0x15, SDB vers = 0x01,
(and sometimes ends with a kernel crash by fsck_hfs)
Things I've tried (without any success):
- /sbin/fsck -fy (in single-user mode)
- Disabling Spotlight and mds
If you want some more information, feel free to ask!
Greetings
-MrYoranimo
PS: My main language is Dutch, so my English can be bad at some points.

Thank you for your support! This reply is a little bit late, because I was to the camping this weekend.
The only thing I sure do know, is that the iMac has a bad SuperDrive. That's one problem, but I don't really wanna use it, and you fix everything by Single-user mode and when I get to the desktop to test things and change stuff in the Preference Panes.
What also came to my mind was that there also is a problem with the videocard (driver), because sometimes when I boot into Single-user mode, I can see some white pixels which aren't supposed to be there. And when booting from SUM you can see that some of the colors are different and there are weird patterns on the screen.
I also tried to setup a NetBoot server on this computer (MacBook Mid 2010) with just Lion 10.7.4 on it, but I'm not that expert and I didn't really find the good posts on the Internet, although I tried it with the Server applications and both Server applications and DeployStudio. But I didn't succeed.
I don't really like buying a new FireWire hard disk or external FireWire dvd reader/writer, except if it has USB support, because my MacBook doesn't support FireWire, and I really wanna make use of it then.
If I know more or have fixed it, I will surely post again here with what I did to fix it (if no one else has posted here already ).

Errors while Changing the Database to Mutli User Mode from Single user mode in SQL Server 2012

Hi,
Good Afternoon :). Need your help in resolving one of the issue with SQL Server 2012.
Today, we kept one of the database in the Single User mode and wanted to bring back to Multi User mode. But we are getting the below error. There are no user sessions connected to this database which are blocking each other. I see multiple
SYSTEM sessions are in blocked state.  The blocking is not cleared even affter restarting the SQL services.
Verified the SQL Server Errorlog and couldnt get much useful information to troubleshoot the issue.
pasted the information from the sys.sysprocesses as well for your kind reference.

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.

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:

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

Ibook left hanging! Got info from single user mode - can u translate?

Hi, am panicking here so help really appreciated!
Got my ibook, G3, 17" screen. It won't start up. It goes as far as the spinning circle of lines. Tried to get into single user mode (got Applejack there) but it ends up saying 'we are hanging here'.
The lines previous to that include the following (don't know if any of this is useful as don't really understand it):
nfs_mountroot failed: 9
nfsboot: ntworking not initialised
panic (cpu0): nfsbootinit failed with 6
latest stock backtrace for cpu0:
backtrace:...lots of numbers here...
Proceeding back via exception chain:
exception state:....lots of numbers here...
Kernal Version:
Darwin kernal version 7.90
dates and release info here.....
No debugger configured - dumping debug information
MSR=00001030
latest backtrace for cpu0:
Backtrace:...
...and then it repeats most of that again until it says:
panic: we are hanging here
and I can't type anything. The cursor just sits.
Have also tried disk utility when booted from cd. It tries to verify the disk but says:
Catalog file entry not found for extent.
The volume needs to be repaired.
Volume check failed.
Error: the underlying task reported failure on exit (-9972)
1 volume checked
0 HFS volumes verified
1 volume failed verification
And it says the same when I try and repair the disk. Do I need to erase the disk? I do back up regularly onto zip disks.
Tried to reinstall system software but when you are prompted for a place to install it onto, there are no disks shown!
How bad is it????

Hi, Nikki.
What happens if you try to start up in Safe Mode? This will take awhile longer than a normal startup because it does a file check and repair of the hard disk.
If this works you will see your normal desktop. Once completely started up, try to restart normally, and go to Applications/Utilities/Disk Utility and repair permissions on the hard drive.

Can I access Terminal from Single User Mode?

So I have an early 2011 MBP that is having the graphics switiching problem that's been well documented in some other threads recently:
https://discussions.apple.com/thread/4766577?start=120&tstart=0
http://appleinsider.com/articles/13/10/14/apples-2011-macbook-pro-lineup-sufferi ng-from-sporadic-gpu-failures
Basically, I cannot boot because it goes to a white screen after the apple logo.
I found these terminal commands that will shut off the discrete graphics card so that only the integrated graphics will run, which would be an ok solution because I mainly use the computer for Recording/Mixing etc with Logic Pro, so I don't really need the more powerful graphics.
http://forums.appleinsider.com/t/160161/apples-2011-macbook-pro-lineup-suffering -from-sporadic-gpu-failures/80#post_2420378
But I of course can't access Terminal because I can't get past startup. Is there a way to get to terminal and/or enter these commands while in Single User Mode?

Are you referring to these
You can move the kext out with these commands:
> mkdir DisabledExtensions
> cd /System/Library/Extensions
> sudo mv ATIRadeonX****.kext ~/DisabledExtensions (replace asterisks with your model's numbers)
> sudo touch /System/Library/Extensions
If so there is nothing to take, the commands are physically removing system files. Once those files are moved there is no way for them to go back unless you put them back or you do an install of the OS.
But I am surprised that Safe mode does not work for you. In Safe mode the system only uses the onboard graphics. Are you certain you ere booted into Safe mode? When in Safe mode the words Safe Boot will appear in red letters at the top of the login screen. Did you see that? I ask because it is easy to mistime the Shift key press during boot and not actually get into Safe mode.
Perhaps you problem something different?
