Did you run the hardware test already by pressing the D key when starting up? Try force booting by turning off mac with the installer inside your cd rom then turn it on and press and hold down ctrl+left shift and delete key

    Try to hard reset it, then you'll have to reinstall disc. turn it off and hold down option key then turn it on, it will ask for the admin password

Osx 10.0.3 lost password


Try this...

Hold Apple+S when booting to enter single user mode
  • #sh /etc/rc
  • #passwd yourusername
  • #reboot
If you can't recall your user name, you can either look in the /Users folder (the directories are named by user), or run "niutil -list . /users".
Also, on older systems the /etc/rc script isn't available, apparently. If that second step fails, try mounting and starting the base services manually:
  • #/sbin/fsck -y
  • #/sbin/mount -uw /
  • #/sbin/SystemStarter
I've had to do this a couple of times for friends when they've bought a second hand machine, and once when I had a momentary brain lapse and forgot my own password. Works like a charm, though you'll loose any passwords stored in your keychain.

I forgot my password,its an apple mac book model A 1811


Assuming you haven't locked out OpenFirmware, it's a pretty simple task to change your password back to something you know.

Here's how:

  • Hold Apple+S when booting to enter single user mode
  • #sh /etc/rc
  • #passwd yourusername
  • #reboot

If you can't recall your user name, you can either look in the /Users folder (the directories are named by user), or run "niutil -list . /users".

Also, on older systems the /etc/rc script isn't available, apparently. If that second step fails, try mounting and starting the base services manually:

  • #/sbin/fsck -y
  • #/sbin/mount -uw /
  • #/sbin/SystemStarter

Password problem


Here is a quick fix for resetting your Mac password.

1. Hold Apple+S when your Mac is booting to enter "single-user" mode.
2. Type "sh /etc/rc" without the quotes.
3. Type "passwd USERNAME" without the quotes, replace USERNAME with your actual Mac username you forgot the password to.
4. Reboot your Mac by typing "reboot" without the quotes.

Hope this helps.

How i transfer data from window to linux


Depending on your linux distrobution, you will need to check the /etc/samba or /etc/smb configuration file, within that file there will be a place to set your windowsfile sharing password. then you will be able to transfer data across the local network between your linux / windows machine again..

however, if you've actually changed the password for the linux user account that enabled the samba file sharing, you will need to either remember that password, or set a new one from the root account byt typing the following command in a terminal / bash / shell session:

Task: Set or change user password Type passwd command as follows>
$ passwd <user>

Output: Changing password for <user>
Enter new password:
Retype new password:
passwd: password updated successfully
NOTE: when typing the password, you may not see the password you are typing..
You need to replace <user> with the username you are changing the password for.

Please advice me as soon as uyou can ..thx


Start troubleshooting the problem by checking the physical layer (Plugs, Jacks, Cables). Replace them with known working equipment.

Once you have traced the line from your Cisco to each other end (through to ISP, and to network switch), then reset your error counters, by restarting the cisco.

Check the ethernet interfaces on the network switch and the Cisco. Make sure they are both set to Autonegotiate or both set to the same settings like 100mbs Full-duplex. If they are not communicating the same way lots of errors will be generated.

Mac G5 startup problem


Try an archive and install of the OS. This will save your settings and files but reinstall the OS. You can do this by booting to the cd and choosing archive and install instead of erase and install. If it happens again, it could be a slowly failing hard drive developing bad sectors, or the less likely of bad ram.
