G5 freezing - no problems with ASD - crashing also in single-user-mode
Hello,
I have a PowerMac7,1 with MacOS X Server 10.5.8, which today started freezing and restarting.
After the system froze, sometimes it restarts automatically, or I have to manually reboot it with the power button. In both cases the restart also froze!
The only way to start the system is the clean the PRAM, but after a while it is crashing again!
I managed to run the full ASD 2.5.7 test without error for a few hours (then I stopped), and with the install DVD I also managed to run the system repair (there was nothing to repair).
Both from the system and from the install DVD I cannot run the repair permissions (it freezes!). So I tried to execute "fsck -fy" from the single-user-mode, but the computer froze again!
Is there something else I can try?
Thanks a lot!
Two things: DiskWarrior. New HD.
It seems that the crashes are coming into play when the HD is in the game in a meaningful sense, which isn't the case with the install disk or ASD, unless you are trying to do something like disk repair or permissions repair from the install disk. What's interesting is that you can boot into single-user mode, but when you invoke fsck, you crash, whereas disk repair from the install disk, which in essence fsck, runs and reports no errors.
You can also try a safe boot and see how things run there. If you can do that, I would suggest running AppleJack on the system, if you can.
Finally, it's possible that NVRAM has gotten corrupted (a possibility but not a high possibility) so an NVRAM reset might help things out.
After trying the safe-boot and NVRAM routes, if no help, my next tool would be DiskWarrior. In the past, I have had situations where DW found problems that Disk Utility didn't find, though that was in DW 3, probably. Fortunately (knock on wood) DW 4 has not had to confront a disaster situation yet for me.

My HP Pavilion Desktop has 504 MB of Ram and I am using high speed internet connection. Because it was crashing so much, I used the uninstall program for Flash player to uninstall Flash, I checked my registry and removed anything I saw that was Flash. I then uninstalled Google Chrome and Mozilla Firefox, then I reinstalled the most recent versions from their websites. I did the same for FlashPlayer and Shockwave Flash. I went to the Adobe website and had them check to see if it was working and it shows I have FlashPlayer 10.3.181.36. The page that shows which version of flash player goes with Windows XP states that I should have 10.3.181.34 (This is what I thought I had before I updated, I was having the same problems). When I went into my computer to see what version I have, it shows 11.5.9.620 Activex and both Flash Player and Flash Player Object is listed as 10.3.181.34. My firewall for Windows is set to medium. I also am running Norton Internet Security. It takes anywhere from 3-6minutes for some of my games to load, and I have to refresh at least 3-4 times in order to play. When I do start to play it freezes frequently and I use escape to free it up. This has been going on for a month. I have no idea what to do. I am not very computer savy and I have been learning as I go. -

Has anyone had a problem with CS3 crashing after downloading OS 10.8.1 on a imac?
Peggy
You are probably correct. I tried all different variations to test it. As long as I quit each document separately, i.e., red dot it, I seem to bring up only one document after that whether I click on the document itself or open it within pages. The same is true with numbers.
Two more questions:
1) can you turn off the "resume" feature? If so, how? I could not find a way to do it.
2) why the "save a version" feature in pages? What happened to the old "save" and "save as" features?
Thanks so much, you saved me a lot of frustration but I am still going to install MS Office for Mac.

I have continuous problems with my iPad Mini, and it is getting worse! Newstand application keep pausing or crashing, websites keep hanging first time in but then open fine the second time, and I have problems with applictions crashing. Has anyone experienced similar problems and any suggestions?
Has the device always behaved this way? Did this start as a result of an update to the iOS software? If the problem is that bad, you should probably restore the iOS software and then restore from a backup. If that fails, restore as new and rebuild the device. If that fails, it's time for a trip to an Apple Store to let them have a look at the iPad.
Use iTunes to restore your iOS device to factory settings -
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.

I've been having trouble with my ibook g4 lately; it won't fully boot and if it does (which is rare) it will suddenly freeze. I can still move the mouse, but the programs stop. I cannot enter safe mode (whenever I hold down shift for a certain period of time the computer turns off completely) and when I go into Single-User Mode this is what I get:
USBF: 21.984 OHCIDriver: OHCIRootHubPortPower bit not sticking (0)
USBF:22.807 [0x162a400] the IOUSBFamily was not able to enumerate device
jnl: replay_journal: bad block list header @ 0x6e4000 (checksum 0x0 !=ffffffff)
jnl: journal_open error replaying journal!
hfs: early jnl init: failed to open/create the journal (retval 0)
also: singleuser boot -fsck not done root device is mounted read only
when I run fsck: **checking catalog file.
Invalid record count
(4, 12)
**volume check failed
Alright, I don't expect to know what all of this means, but was wondering if anyone knows what it might indicate and any solutions. Thanks in advance for any advice. And again, I cannot seem to boot in safe mode.An "Invalid record count" means you have some file directory damage. The file directory is the file that tells your Mac where all the various files on the hard drive are physically stored. These errors could be what's causing the messages you're seeing in the command line.
You may not be able to repair a problem like this with fsck in single user mode or with the Disk Utility on your Mac OS X install disk. But starting up from your install disk would probably be the next step to troubleshooting. Put your install disk in the iBook, restart and hold down on the "c" key. The installer will startup and ask you to select a language. Then, instead of continuing to install, if you have a Mac OS X 10.3 disk, choose to open the Disk Utility from the Installer menu or, if you have a Mac OS X 10.4 disk, choose to open the Disk Utility from the Utilities menu. Select your hard drive and click "repair disk" on the right-hand side. Hopefully it can repair the problem. When you're done, you can quit the Disk Utility and then quit the Installer to restart back to your hard drive.
If the Disk Utility cannot repair the trouble, then you might need a more sophisticated tool like to repair your drive.

Hi, my iMac G5 is freezing right away when I boot in single user mode. I mean right away at the prompt. I cannot even start typing anything. The fan start at 100% and I have to hard shutdown the machine. This happens ALL the time I boot in single user mode. EVERY TIME no exceptions.
I am trying to run a memory test (using MEMTEST) to see if my 1gig memory is defective. My iMac freeze randomly without me able to find a consistent pattern.
Questions:
1- Does the freeze at boot could be a problem with me using a bluetooth keyboard and mouse?
2 - If not, the fact of freezing at boot in Single User mode a possible explanation of memory problem (does the single user mode lock-up memory that could be bad?) as my iMac do not freeze (for a while) when booted in multi-user mode.
My setup: 2 ghtz iMac G5, 1x1gig Kingston PC3200 memory (sold and installed by my Apple reseller). My G5 is 7 month old still under warranty.
I am new to the Mac - I switched from PCs.
Thanks for the help.
iMac G5 + Thinkpad T40 Mac OS X (10.4.2)With the PC-Viewsonic keyboard, Pierre, the symptoms you describe are exactly what you would expect.
Third party, non Apple, keyboards, even wired ones, can't usually be used to do anything beyond simply starting up in SU mode (you can start them up and get to the prompt, but when you are there you can't do anything further).
The same applies to Apple Wireless keyboards when running versions of the OS 10.4.2 or earlier, or if the bluetooth firmware isn't up to date. Again, you CAN start them up in SU mode, but you can't do anything with them after you reach the prompt.
As far as the BT issue goes, as you say its running 10.4.6 I'm beginning to wonder if there was a problem with one of your OS updates. I'd be inclined to download a fresh copy of the full 10.4.6 Combo updater, and run it again. Probably worth running the Blue Tooth firmware update again, too, just in case.

IBook Mac OS 10.3.9 not booting, even crashing in single-user mode
Yeah so about 2 weeks ago my iBook started crashing, then wouldn't properly re-boot. Gradually, it would start crashing after being on for less and less time until now it gets just past the apple symbol and then freezes on a blue screen.
I've been using the online help but now it's even freezing during single-user mode, meaning i can't even perform fcsk!! I can't even boot up on the Mac OS X CD to re-install the OS. Anyone got any idea what's wrong or what I can do? Thanks, RobWhat, exactly, is preventing you from starting up from the Mac OS X install disk?
Have you added any RAM yourself? You might try taking it out to see if that helps. You might also try to run the Apple Hardware Test. Depending on which bundle of install disks you got, it may be on the Mac OS X install disk or it may be a separate CD of it's own. It should be marked "AHT" and a version number on the disk. Put that disk in the drive, restart and hold down on the "option" key. This will give you a Startup Manager that should allow you to select the hardware test and continue (click the right arrow to continue). If you can't even get that far, then you probably have a hardware failure and you'll need to take your iBook in for service. What is your location?

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.

Hi everyone,
I'm simply all out of ideas on what to do - my best guess is the problem is not specifically hard-drive related since all the 'normal' fixes just won't work.
What could be the cause of my issue? The only way i've managed to keep the Macbook Pro on for longer than a minute is through target drive, where it seems to work just fine - i can access everything. To sum up everything:
1 - I tried resetting the PRAM
2 - I tried to go in to safe mode, it shut off before i could type the password
3 - I tried fsck -fy command from single user mode, sometimes i can get to actually typing it but mostly it shuts off before
4 - I tried to repair disk via target drive - success, no problems detected (and it didnt fix my issue)
5 - I reinstalled OS Mavericks.
The Macbook Pro previously had some problems with the power-button not working properly (a mac-cunning friend of mine had to open up the mac and start it by swiping to metal pins on a specific (battery/power?) part inside it. The problem kinda went away afterwards but it might be related to this?
This is way off my comfort zone of 'diagnosing' issues, so I'm crossing fingers for some good advice.
Thanks,
Aske
DenmarkI think you're right.
If it's hardware related, is it possible to guess at what it might be? It would be nice to know how much I should expect to pay for a repair before actually getting it fixed. -
Bluetooth problems in single user mode
I've already checked some of the discussions on this topic but did not find the answers that i am looking for. i need to get into single user mode because my computer will not completely boot the osx. however, after i hold down the command-s and the promt comes up, it is af if i have no keyboard at all. i cannot type anything. is this due to the fact that i have a bluetooth keyboard? would going out and purchasing a usb help me out (because i have read some posts that they have the same problem with a usb)? is there any way around this. single user is becoming one of my last alternatives to having to reformat. please help!
bestA wireless bluetooth keyboard would only let you boot into Single User Mode, after that, you will need a regular USB keyboard to type in the prompts, same goes when doing a Hardware Test using the disc provided.
As for some users posted on this forum saying they have not able to continue the Single User Mode under a regular USB keyboard, I am afraid I am one of them... I have not been able to solve the problem as yet and it is kinda "annoying" that there "may be something wrong" with my iMac that I cannot perform fsck, nevertheless I have regularly booted from the OS disc and run Disk Utility, which is equivilent to booting to SUM, but supposingly much better, and my HD checks out fine... so at the moment I have no worries.
In my post there is another person who has regularly keeping me update about this problem and has deduced it maybe due to the internal bluetooth module and the USB inside... rather complex issue that may require me lengthy conversation with AppleCare or have something replace, or "worse" have my iMac sent away for a time for repair or replacement. Since my iMac is doing quite fine, I'll live with it for the moment...

below the original doc on msdn:
Start SQL Server in Single-User Mode
Provide Feedback
Under certain circumstances, you may have to start an instance of SQL Server
in single-user mode by using the startup option -m. For
example, you may want to change server configuration options or recover a
damaged master database or other system database. Both actions require starting
an instance of SQL Server in single-user mode.
Starting SQL Server in single-user mode enables any member of the computer's
local Administrators group to connect to the instance of SQL Server as a member
of the sysadmin fixed server role. For more information, see Connect to
SQL Server When System Administrators Are Locked
Out.
When you start an instance of SQL Server in single-user mode, note the
following:
Only one user can connect to the server.
The CHECKPOINT process is not executed. By default, it is executed
automatically at startup.
Note
Stop the SQL Server Agent service before connecting to an instance of SQL
Server in single-user mode; otherwise, the SQL Server Agent service uses the
connection, thereby blocking it.
When you start an instance of SQL Server in single-user mode, SQL Server
Management Studio can connect to SQL Server. Object Explorer in Management
Studio might fail because it requires more than one connection for some
operations. To manage SQL Server in single-user mode, execute Transact-SQL
statements by connecting only through the Query Editor in Management Studio, or
use the
sqlcmd utility.
When you use the -m option with sqlcmd or
Management Studio, you can limit the connections to a specified client
application. For example, -m"sqlcmd" limits connections to a
single connection and that connection must identify itself as the
sqlcmd client program. Use this option when you are starting
SQL Server in single-user mode and an unknown client application is taking the
only available connection. To connect through the Query Editor in Management
Studio, use -m"Microsoft SQL Server Management Studio - Query".
ShawnHi Shawn Xiao,
For starting SQL Server instance in single user mode, we can add –m; parameter in SQL Server Configuration Manager, also we can run CMD with ‘Run as administrator’ and input the following statement.
NET START MSSQLSERVER /m
I do a test in SQL Server 2014 Express version, after starting SQL with Single User Mode, SQL Server will only accept one connection. If you connect to SQL Server with a user account, the following error will occur.
Login failed for user ‘domain\username’. Reason: Server is in single user mode. Only one administrator can connect at this time.
However, in your situation, you can connect to SQL Server and run T-SQL statement successfully, it can be due to connection with the administrator account in your sqlcmd.
For more information, you can review the following article.

I can only start my iBookG4 after deleting preferences. I have to go into single user mode to do so. If I don't go into single user mode, the computer shuts down during boot up. What might be the problem? How can I fix this?
I do not have a startup disk. I did try fsck (based on what I learned from your reply-thank you). This failed (fsck); here is the message:
** Checking catalog file.
Invalid key length

** Volume check failed.

I am sure this is an easy fix; I just have no clue how.
