Can't log-in in mac os x... - Apple Mac OS X 10.4 Tiger for Mac

Please contact tech support at easylist.com.au for assistance.

You are referring to two different computers. In either case it appears to be an operating system problem. You need at least OS 10.7.X Not OS 10.6.8.

you will need to find your original OS disks or the DVD for the operating system you are currently using, perhaps mac OS 10.5 or OS 10.6?
then boot up from the cd, by holding down the c button when restarting.
when booted up from the cd, continue through until you get the menu's at the top of the screen, you can choose reset password from there.

Thank you for contacting Fixya Support, I am glad to assist.

If you are unable to gain access via the password to login to your Mac OS X desktop, you are going to reset your password.

What you will need to do is use the Mac OS X restore (Disk 1) or the Mac OS X installation disk which came with your Macbook Pro.

Now perform this process:

* Insert your install disc
* Reboot your Macbook Pro

* Press the C key on your keyboard and hold until you see the white screen, grey apple, and eventually the spinning gear.

* Release the C key when you see the spinning gear

* When you reach the Mac OS X install environment, click past the language screen.

* From the Installer Menu bar select "Utilities" and then "Reset Password".

* Within the Reset Password utility, select the User Account you need access to.

* Reset the password.

* Quit the Reset Password utility when you have reset and confirmed the new password

* Quit the Installer and restart your Mac..

* At the log in window, enter your username and newly reset password. You should now be able to successfully log in. * I hope this helps.

Step 1: Start up from a Mac OS X Install CD. This hardest part of this technique may be laying your hands on a Mac OS X Install CD when you need one. Use a version that is close the the version of Mac OS X you have installed.
Hold the C key as the computer starts to boot from the CD.
When the installer starts, choose your language, and you'll proceed to the welcome dialog.
Step 2: Choose Reset Password from the Utilities menu. Tip: In previous versions of Mac OS X (10.2 and 10.3), you can find the Resent Password option under the Installer menu instead.
Step 3: Select your Mac OS X hard disk volume. Select the user name of your original administrator account.
Important: Do not select "System Administrator (root)". This is actually a reference to the root user. Do not confuse it with a normal administrator account.
Enter your new password. Click Save.
Step 4: Quit the Reset Password tool, and Restart your Mac.

I would boot the computer in safe mode and here is the instructions.
Learn how to start up in Safe Mode.
Products Affected Mac OS X 10.4, Mac OS X 10.3, Mac OS X 10.2, Mac OS X 10.5
To start up into Safe Mode (to Safe Boot), do this:

1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

During startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
During startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.


while your in safe mode see if you can uninstall the drive software and reinstall it

Give your mac a few moments to wake up before you try to connect iDisk.

If this didn't solve your problem

1. From the Apple menu, choose Log Out.
2. Log back in.
3. Try to connect to your iDisk.
4. If the issue persists, restart your computer.

You should now be able to connect to your iDisk. However, if the issue persists, follow
these additional steps:
1. Open System Preferences.
2. Click MobileMe.
3. Click Sign Out. Note: This will unregister your computer from syncing with MobileMe, and disable iDisk Syncing if it is enabled.
4. Retype your MobileMe account name and password.
5. Connect to your iDisk.

Follow these steps -

1. Start up from a Mac OS X Installation CD (one with a version that is closest to the version of Mac OS X installed on your Mac).
You should first disable Open Firmware password protection, if it is enabled. Hold the C key as the computer starts.
2. From the Installer menu Choose "Reset Password" (if you have Mac OS X 10.4 Tiger this will be the "Utilities menu").
Tip: If you don't see this menu or menu choice, you're probably not started from the CD yet.
3. Select your Mac OS X hard disk volume.
4. Set the user name of your original administrator account.
Do not select "System Administrator (root)".
5. Enter new password.
6. Save.
