10.4.3 and Single User Mode, now Wireless Keyboard can

Hello all.
IN case you haven't found out which I did, just to let you know, with the latest OS 10.4.3 update, now you can boot into Single User Mode (fsck) with your
b wireless keyboard
and still at the same time
b continue to complete fsck process with your wireless keyboard!!
No more switching to a regular wired keyboard just to complete the process!

Hi Steven, bit unclear on a couple things.
When I went into single user mode the fans went wild. But I knew this to be normal and proceeded with repairing the disk
Normal for fans to go wild in single user or when repairing the disk?
I replicated the problem – applied the same fix and again every thing was normal.
The problem being screaming fan and the fix being resetting SMU? (unplug for 15secs). So how did you replicate it, and is it really fixed now?

  • Difference between emergency state and single user mode ?

    Hi,
    I want to know the difference between emergency state which we normally use in suspect mode database and single user mode.
    Navakanth

    Emergency/suspect mode is tells you the state of the database and database is not available for user action but where as single user mode tells the user action preference. Database is active and available for the user action.
    You can refer 
    http://msdn.microsoft.com/en-us/library/bb522682.aspx
    EMERGENCY
    The database is marked READ_ONLY, logging is disabled, and access is limited to members of the sysadmin fixed server role. EMERGENCY is primarily used for troubleshooting purposes. For example, a database marked as suspect due to a corrupted log file can be
    set to the EMERGENCY state. This could enable the system administrator read-only access to the database. Only members of the sysadmin fixed server role can set a database to the EMERGENCY state.
    SINGLE_USER
    Specifies that only one user at a time can access the database. If SINGLE_USER is specified and there are other users connected to the database the ALTER DATABASE statement will be blocked until all users disconnect from the specified database. To override
    this behavior, see the WITH <termination> clause.
    The database remains in SINGLE_USER mode even if the user that set the option logs off. At that point, a different user, but only one, can connect to the database.
    Before you set the database to SINGLE_USER, verify the AUTO_UPDATE_STATISTICS_ASYNC option is set to OFF. When set to ON, the background thread used to update statistics takes a connection against the database, and you will be unable to access the database
    in single-user mode. To view the status of this option, query the is_auto_update_stats_async_on column in the sys.databases catalog view.
    If the option is set to ON, perform the following tasks:
    Set AUTO_UPDATE_STATISTICS_ASYNC to OFF.
    Check for active asynchronous statistics jobs by querying the sys.dm_exec_background_job_queue dynamic management view.
    If there are active jobs, either allow the jobs to complete or manually terminate them by using KILL STATS JOB.

  • Won't boot normally or in recovery and single user mode, safe mode hangs up halfway

    iMac locked up with visual glitches while playing the Mac beta client of League of Legends. Had to force a shutdown by holding the power button. Now it won't boot; after the Apple logo and spinning wheel I just get a white screen. I tried launching in recovery mode, that didn't work. Then I tried safe mode; the bar filled a little over half and then nothing but white screen. I was able to boot single user mode once; ran fsck -fy and rebooted, still white screen. Now I can't get back to single user mode. I booted with command option P R to reset the NVRAM and got the second chime, but still nothing.
    Luckily all my important files are in the cloud, but I'm really hoping my computer isn't completely dead. I haven't had any issues in the past. I've even been playing LoL for over a month with no issues, until now when I tried to play the newer game types, Dominion and ARAM; both caused visual glitches forcing shutdowns. I was able to restart my computer with no problem after the first two visual glitches, but after the last one I am stuck at the white screen as I described above.
    Thanks in advance for your help!

    I'd bet the drive is damaged. You could try reformatting if possible. Again, you are booting from the Recovery-10.8.2 disk if you can. If you can't, then you will need to use the installer disc that came with the computer.
    Install or Reinstall Lion/Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
            the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • Screaming Fans ,10.4.3., and Single User Mode.

    I wanted to add my experience with the screaming fan problem and 10.4.3.
    When I ran Disk Utility and used the “verify disk” option I received some minor errors and proceeded to boot the OS X install disk and run Disk Utility from there. When I did I received no errors. Rebooted back to 10.4.3 and reran disk utility and received the same minor errors. So I read one of the Mac sites that stated that one needed to run in single user mode and execute “fsck – f”. This where the “fun” started.
    When I went into single user mode the fans went wild. But I knew this to be normal and proceeded with repairing the disk (which was successful as evident with no errors being reported while booted to the desktop and running live verify disk. But before I got to that point the fans remained screaming after the reboot to 10.4.3. I reset the PRAM and NVRAM but to no avail. The fans would not quite down. The fix turned out to be very simple – I unplugged the computer (after shutting down) for about 15 seconds. Re plugged it in and it was fine after that. Fans back to normal! I replicated the problem – applied the same fix and again every thing was normal.
    I just thought I would pass this on to the iMac community.

  • I made changes in the single user mode - now my MacBook Pro does not boot anymore.

    Hello apple support community,
    I made changes in the single user mode and my MacBook Pro does now not boot anymore. It displays a grey bar and the "work in progress" wheel. My intention was to change my admin password following these steps:

    however, I have to admit that there was a typo sneaking in - oops!
    Any idea how I can undo changes made in the single user mode?
    Thanks in advance for your support - I hope I don't sound to nooby

  • Password protected EFI and Single User Mode

    Hello Community,
    if I protect the EFI with a password than the single user mode is disabled. But I thought that I can enter the single user mode by entering the EFI password but no password prompt appears. Only the possibility to change the startup volume is accessible by a password prompt. Do I miss a possibility or is the only way to enter the single user mode by bypassing or disable the password by using the firmware password utility on the installation disk without violence?
    BTW: I know the act of violence by changing the RAM configuration but this isn't the way I want to describe in the system documentation
    Thx in advance & Bye Tom
    Message was edited by: prontosystems

    Try holding the Option key while booting. It should ask for the password, then allow any boot options after you select the drive. If you boot from the install DVD (using the Option key and password), you can use the "Utilities" menu to disable the password, after choosing your language.

  • Boot in Single User Mode gives no keyboard control (wireless (ALU keyboard)

    Power up Mac Pro
    when startup sound comes I enter cmd+s
    System boots into Single User Mode
    until it displays: root#_
    Now I am not able to type anything on the keyboard to display on the screen
    What could be the cause of this strange behavior?
    I am using the wireless apple alu keyboard with the magic mouse
    Oh, I also tried this with an USB attached keyboard and I had the same result. Booting into Single User Mode went fine but then the keyboard did not do anything after once we were in Single User Mode.
    Other than on this occasion the keyboard (and mouse) works fine. I've also done the latest firmware upgrades to the keyboard as well. All system software is at the latest revisions.

    20" G5 Imac 1.8Ghz Mac OS X (10.4.8)
    You may want to find *Using Tiger* forum or PPC G5 iMac; or, go back to earlier versions of Applejack (which always from my experience worked 100% on Power Macs and pre-Leopard).
    AJ and SU just use Apple's diskutil and you are always better off with something like Disk Warrior, AJ/SU is handy when you don't have another drive handy to boot from or just wanted to clean up caches or something.

  • 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?

  • Why won't single user mode recognize /sbin/mount command?

    I need help from people who are knowledgable abou these Mac wonders of the world and single user mode.
    I'm trying for the life of me to run "memtest" in single user mode and am finding it impossible.
    After I boot into single user mode, I get a "Shell>" prompt.
    I type in /sbin/fsck/ -y to do some check thing.  I then type in /sbin/mount -uw /
    Both times I get an error saying that "/sbin/yada yada yada  is not recognized as an internal or external command, batch or whatever"
    No command work at all.  I have no clue what I'm doing and am using instructions from where I got the memtest app.  Sure I could just run it from the Terminal but then you're not testing all of the RAM, only the available portion.  There's a huge chunck that won't be tested as OSX is using it.  I want to do this as I just upgraded RAM to 8G with Crucial and now my MBP is acting very slow and weird.
    HELP????  Why does this have to be sooooo hard.

    I found the solution to the problem.  Somone on a different forum had the same issue at one time.  The problem is my use of Refit.  When you hold Command-S at start when using refit you go into a single user type mode inside the refit shell.  So it is something different.
    Instead I needed to let the Mac boot Refit like normal.  With the Mac partition highlighted press "F2" and it will display boot options for the Mac partition.  One of them is Mac OSX single user mode.  Simply select and hit enter and then I enter the correct single user mode and I'm off.
    Then everything works like it should.  I was my own undoing with my use of Refit. 

  • HT1492 Single user mode not working.

    Whenever I hit command-s to go into single user mode it doesn't work. I used to do it all the time to help my grandma who doesn't let me know her password, but always forgets it reset her computer. Please help!

    Thank you! The thread you posted had my problem exactly, and the solution. It was the Macally keyboard, so I uninstalled the driver (and single user mode worked), and then I installed an older driver, so now my keyboard works AND single user mode works. If all of my computer problems could be so easy...

  • Single User Mode Question

    I use single user mode to do fsck because doing it on a live disk takes way too long. I was wondering if there is a way to repair permissions from single user mode. Thanks

    1. what does AFAIK mean?
    As Far As I Know
    2. What I have gathered is that it is near next to y difficult to repair permission fro the CLI and single user mode.
    Correct. You can't use diskutil because the disk framework isn't loaded. You can do it if you're booted from an install DVD, though.

    Thanks,If you are asking whether you can boot that system using a CD/DVD of a newer release...
    ... then go do system maintenance tasks...
    Yes, that is perfectly acceptable.
    If you are asking whether you can boot that box using a CD/DVD of a newer release...
    ... then copy files fom that CD/DVD and overwrite existing files...
    No, that would possibly muck up your system and you would have to wipe it and reinstall fresh.

  • Resetting the Admin password in single user mode

    Ok, my friend bought an old Imac from someone she went to school with with OS 10.4.2 on it. It works fine except that she can not install any programs because there is an admin password that she does not know. She asked the person she bought it from, he says he doesn't even remember setting a password. Normaly with this issue id just pop in the install disk and reset it from there, except neither of them have the install disk, and my install disk is to current for the machine. Does anyone know how I can reset the admin acount using single user mode commands? I can do it on my Mac Book pro but it doesn't seem to work the same way on 10.4. Please help!
    EDIT: It is a Power PC G3 if that helps.

    Message was edited by: CartooNxHerO
    You do not need to delete "the users home folders". Nor do you need to delete the netinfo database. Here are two proceedures:
    Change Password
    Mac OS X:
    Changing or resetting an account password via GUI:
    Resetting a user's password
    Resetting the original administrator account password
    http://docs.info.apple.com/article.html?artnum=106156
    You do not have a CD/DVD
    Changing password from single user mode:
    You can also change the administrator's password from single user mode or create a new administrator account.
    You need to get into single use mode for steps one and two that are listed below.
    This page will tell you how to get into single user mode.
    http://support.apple.com/kb/HT1492
    Basically, you hold down the command-s key then powering on your machine. The command key has a little apple symbol on the lower left. It is between the alt/option key and the space bar. On a PC keyboard, it will be the windows key, I think.
    1) You can change the password on an account. ( Do you know Unix. You are in a Unix single user console. ) The setup commands you need should be listed on the screen. For Mac OS 10.4.11, the commands are:
    # Type the follow two instructions to access the startup disk in read/write:
    /sbin/fsck -fy
    /sbin/mount -uw /
    # Start up some utility processes that are needed.
    sh /etc/rc
    # You will probably need to press the return key once the system stops typing.
    # To find out the users on the system type, use the list command. The l is a lower case L:
    ls /Users
    # One of these accounts will be the administrator.
    # Pick one of the users which I'll call a-user-name and type it in this command:
    passwd a-user-name
    # and enter the new user password. You need six characters.
    # You will need to enter your password twice. Your typing will not show up on the screen just
    # press enter when you complete the typing.
    # For cryptic information on these commands try:
    man ls
    man passwd
    The root account isn't enabled by default. I am not sure if changing the password on root will enable it.
    2) Get the Mac to set up an additional administrative account. You can then change the password on your old account.
    Start with your computer power off. Hold down command-s. Power on your computer.
    Type in the following:
    The first two commands will depend on your release of Mac OS X. Look at what is typed out in the console to determine the exact format.
    # Type the follow two instructions to access the startup disk in read/write. Press return after each command.
    /sbin/fsck -fy
    /sbin/mount -uw /
    cd /var/db
    pwd
    #List all files. The l is a lower case L.
    ls -a
    #The move command acts as a rename command in this format.
    mv -i .applesetupdone .applesetupdone.old
    reboot
    Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

    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.

  • Boot Snow Leopard from Thumb Drive in Single User Mode on Macbook Air

    I'm trying to boot from a thumb drive that I transferred the Snow Leopard .dmg on. My macbook air only lets me get into single user mode. Every time I try to boot or enter safe mode or regular mode, the Macbook Air shuts down.

    I do have the installation media on my usb flash drive. I'm sure it's leopard, and the problem is that I cannot get passed the apple logo on boot. The laptop turns off after trying to finish the boot for twenty seconds. However, I can get into single user mode. I just can't seem to install the media in single user mode due to my lack of know how.
