Internal HD on mac mini not well... need to boot in Single User Mode

Internal HD on mac mini not well... need to boot in Single User Mode.
I only have a Bluetooth Keyboard and Bluetooth Mouse so when I try to boot in Single User Mode (to do the /sbin/fsck hard drive fix thing) it doesn't see the Bluetooth Keyboard. What's the solution?
I also used SuperDuper to use as a boot drive but it won't unmount my internal HD. arghh..
Help

I have a corrupt drive and was unable to repair all the errors after booting from OS X installer disk and choosing Disk Utility...
I followed the "boot into single user mode" instructions hoping to complete my repair with fsck, however once I got to the localhost:/ root# prompt, my keyboard seemed to be unrecognized!
I tried 3 different USB keyboards - original Apple USB keyboard, Kensington Mac USB keyboard and an old SGI USB windows keyboard. All were able to enter the apple-S key to get into single user mode but NONE of them were able to type any commands whatsoever.....
I'm thinking my only option is to boot the mini as a target drive off my laptop and try to backup my 30GB of music and photos before wiping the drive...
2nd option might be to try Disk Warrior for $79??
Anyone else have ideas for me?

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.

MacBook won't boot in Single User Mode

My MacBook will neither boot up in Single User Mode nor in Safe Mode. Nor will it perform a PRAM zap. The key-combinations I use during boot-up are OK, because they work well on my iMac. Does anyone know why this is? And of course: how it can be solved?
MacBook: white, late 2007, 13", 10.6.2
iMac: early 2008, 20", 10.6.2
key-combo's used: command-S / shift / command-option-P-R

Called MacHouse, they supposed it could be Firmware-related. Since all software on the MacBook was up-to-date, a Firmware-update could not help me out. They advised me to remove the Mac's memory and reboot, thus forcing the Firmware to get a fresh grip on the installed hardware, including keyboards and the like. I don't understand the technical details of this, but it worked.
Removing both memory-cards made the MacBook make panicky beeping sounds, but removing one of them, rebooting, then reinstalling it and reboot again did the trick. It will now boot in Single User Mode, Safe Mode and Apple Hardware Test.

MAC DUO won't go past BLUE SCREEN on start-up.

Please help!
My mac duo has crashed after a mac software update. Now it won't logon past the blue screen!
I've tried everything online like DISK UTILITY on Mac os x disc and SAFE MODE but no joy whatsoever.
SAFE MODE won't work now after doing it three times. Is this typical?
Should I re-install the MAC OS X using the option to copy existing files and applications?
Any help would be greatly appreciated.

There are two major problems out there right now. That is also part of the problem. We are not used to two problems in our domain.
I own 20 Mac's in my office, and I only did the latest updates on my MacBook Pro 17-inch portable and my G5 Dual 2.3 GHz desktop that has two 30-inch Cinema Displays. Both machines had the Adobe CS 2 Professional Suite with Acrobat Professional.
I had both of the prevailing update problems on my MacBook Pro—1) unable to restart and 2) Acrobat crashing the system.
On the G5, I only had the 1) unable to restart problem.
I won't update the other machines until these problems are resolved by the OEMs.
1) Unable to Restart. Of the two major hiccups out there, the link below indicates Quicktime's update is the source of the 1) unable to restart problem, fixed by deleting startup items, I believe. Again, I had this 1) unable to restart problem on both operating systems (PPC and Intel versions). Recovery of the 1) unable to restart problem is done in in Safe Mode by holding down the Shift key when restarting. This may take a long time to reboot, so keep holding down the shift key until the grey screen and startup wheel is seen. Then delete all startup items and Adobe Version Cue if you have it. (Use Version Cue Uninstaller.)
http://www.macworld.com/news/2006/05/24/cs2quicktime/index.php
2) Acrobat Crashing the System. Acrobat's freezing the entire OS 10.4.6 system is a result of the Security Update 2006-003, fixed by rolling back to a pre-Security Update state using Archive & Install for re-installation of the OS. Archive & Install does not erase your files or network settings. Printers may need to be re-added.
Apple has released two products (QT 7.1 and SU 2006-003) that fouled these systems. Bad Quality Assurance, I think. I am not sure if the Security Update problem is an Apple or an Adobe software problem, i.e., Adobe may have not followed some software guidance from Apple in Acrobat 7.07 or earlier versions. I am certain both companies are aware of the problem, but I am uncertain of the fix for Acrobat. We probably do need to update for security, but I can't live without Acrobat. So I will wait it out sans Security Update 2006-003.

Mac OS X: Gray screen appears during startup < for Mac OS X 10.4, Mac OS X 10.5, Mac OS 10.6:
If you have v10.7.x (Lion) installed, you need to use Lion Recovery to repair the startup disk if necessary or reinstall the Mac OS X.

Hp dv6t won't go past blue screen blinking cursor

Hello,
Please help me figure this out! I have looked at the boards for days and weeks but cannot solve my problem. No matter what i have tried so far, I cannot get past the blue screen with blinking cursor. A couple months ago I was out of town and blue screen came up i was able to hit F4 rapidly and eventually get it to work several different times that trip. Now however, I cannot get anything but blue screen and blinking cursor. Thanks in advance for any help! Heidi

Hi @heididmn1800000,
Welcome to the HP Support Forums!
I am sorry to hear that you cannot get passed a blue screen on your HP dv6t PC. I will try my best to help you with this. To better guide you, could you please tell me the full model or product number of your computer and the operating system that is running on it. Here are some guides for How Do I Find My Model Number or Product Number? and Which Windows operating system am I running?.
In the meantime, here is a document for Troubleshooting Error Messages on a Blue Screen that may Occur During Startup or Boot, that may have a solution for you.
I hope this helps, please let me know how it goes.
Thank you and have a great day!

Old iMac was sluggish and now won't go past blue screen.

We have a pretty old iMac, it will be 7 years old next month. I totally expect for it to slow down and have issues being that old, but was hoping I could maybe get a few more years out of it for my in-laws. We gave it to them 2 years ago and now it's going downhill. It has been sluggish for quite awhile and now will not turn on past the blue screen. No spinning wheel, just a blue screen and an arrow.
Is there anything we can do? Could we perhaps completely wipe the computer as there is nothing important saved on there? Would that even help? We are probably at the end of it's life here, but just thought I'd come for suggestions first.

I suspec the machine has had a hardware failure. If you can run Apple's Hardware Test, you will need the original install discs that shipped with the computer to do this. Run the test in Extended Mode at least 2-3 times back to back. The reason to run it multiple times is AHT is not 100% reliable however if it detects an error the error is correct. If you get an error that means a trip to the local Apple Store or AASP for repair, based on the vintage of the machine I woudl recommend an AASP. If you are aware of AHT then please click Apple's instructions located at:
Using Apple Hardware Test
Good luck!

Why does my mac book pro have a blue screen when booting up for a second just before the login screen

When turning on my Mac Book pro before it get to the log in screen it has a blue screen for a couple of second the goes to the login sreen. It seams to take some time to complete the login to my computer.
can anybody give me some help with this problem.
Thank you

The cable connections have (so far) solved this problem for my situation. Even though the monitor's DVI cable was firmly connected to the mini Display port connector, when I touched it the attached monitor would go 'blue' or lose its connection entirely. After disconnecting and reconnecting this junction the monitors would still take a hit on touching the connection. I also checked the connection of the mini Display port connection to the graphics board and could not push it in any further. However, after a second go-round I unplugged this connection to the board and reconnected it. I am certain it was fully inserted the first time. But, connection contacts can oxidize over time and sometimes it may just need to be disconnected and reconnected to 're-wipe' the connections. This effectively cleans them at the point of contact. So in my case I'm thinking it was the connection age that was an issue more than a 'loose' connection. Either way, I haven't had this issue for the past two weeks.

Mackbook wont log in past blue screen

i have a problem which wont let me log on past this blue screen. ive tried safemode and single user mode but nothing seems to work. this has happened before and somebody used firewire to update my system or something like that. please can u help me to get my computer up and running

Welcome to the fums Kiwi!
Tough to guess on the data loss, having a good backup or two is the only way to be sure... but disk Utility will not likely destroy something not alreadymessed up.
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Apple symbol turns to block on boot screen and won't load past the screen

-This new problem has occured when I boot my G4 MDD.
-The Apple symbol appears on the screen and the loader at the bottom
continues to spin.
-Until a gray block appears in place of the Apple logo.
I can hear the computer still reving up until a certain point then it
seems to give up and the computer stays idle for however long I keep
the cpu on.
I reset the pram and held it for seven times and it worked but, when I
came home later after leaving it on, the tower shut down.
Again the gray block appeared and reseting the pram didn't do a thing.
I couldn't even get DiskWarrior to boot or the cpu to boot into single
user mode or verbose. I even tested each one of the rams to see if that could be the problem.
I'm pretty baffled and I hope this isn't a major problem, it seems it
might be just the hard drive going batty.
Thanks for any advice.

Hi! "it seems it
might be just the hard drive going batty." Sounds like you already know what the problem probably is. Tom

Single-User Mode Copying Files/System Does not Boot Past Apple Logo Screen

I have a Macbook 2.0GHZ, 2GB RAM, that recently tried to download a secuirty and keynot update. Following the download the system will no longer boot past the Apple Logo Screen with the spinning wheel. I do not have access to a OS disk yet or to a firewire cable either. I've have seen posts from others that describe how to use traget disk mode to reinstall the secuirty update manually and then they can boot their computer. Safe mode will not work. I did boot into single-user mode and run the disk utility there and it says my HD is OK. Since I do not have a firewire or an OS Disk, I am wondering if there is a way to copy those files i need to a USB pen stick then install them onto the computer via single-user mode, considering this is the only way I can boot and manipulate the machine at this time. If this is not possible please let me know so I can find a way to scrounge up a firewire cable or disk. Thank you in advance for any assistance.

Thanks to Limnos and BDAqua I know you guys have helped others with these kind of problems from the other posts I read. I just want to list what I did exactly in case anyone wants to try to do this with a usb drive or does not have access to a boot disk or firewire cable.
1: Install security update on a pen drive
2: Boot in single user mode, CMD-S on startup
3: /sbin/mount -uw /
4: mkdir /Volumes/usb (usb can be any name, name of usb drive or anything you want)
5: ls /dev (you need to get the drive listing for the usb drive to mount it appropriately, it should be disk#s# but this is close to what the HD and Cd drives are listed as so you may need to list once before you put the usb stick in and once ater. I had issues inserting the usb drive in single-user mode and it would freeze up the root drive)
6: /sbin/mount_msdos /dev/disk1s1 /Volumes/usb (this mounts the usb drive, i had to use msdos because of how my usb drive was formatted, you may need to check your usb drive format, hfs is the apple format for usb drives but it did not work for me)
7: cp /Volumes/usb/SecUpd2009-001Intel.dmg (this copies the files from the usb drive to the root drivel, at this point you no longer need the usb drive)
8: hdiutil mount /SecUpd2009-001Intel.dmg (this mounts the disk image)
9: cd /Volumes/"Security Update 2009-001" (after i mounted the image this is how it appeared in the Volumes directory, you might need to do ls /Volumes to get the name, the quotes are important to get the whole file directory changed)
10: installer -pkg SecUpd2009-001Intel.pkg -target / (this installs the acutal update, i used the SecUpd2009-001Intel.pkg and it worked though I think you might be able to use "Security Update 2009-001" with quotes as well.)
11: reboot
i hope this helps anyone looking to do this. Thanks again to those who helpes and all the other posts that had information that helped me identify and then fix my issue! I still love my mac.
