Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, 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 at top of the screen. (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. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Thanks again for your help.
I followed your instructions. After the Repair Disk from OS X Tiger, response was no disk errors in green text. Did the safe boot and Repair Permissions from Utilities and response was:
Group differs on ./private/etc/authorization, should be 80 group is 0
Owner and group corrected on ./private/etc/authorization
Permissions corrected on ./private/etc/authorization
Pernission Repair Complete
The privileges have been verified or repaired on the selected volume.
With keen anticipation, I rebooted and tried again to log in with one of the newly created user accounts, but got exactly the same result. I went in and re-set the password for one of the accounts, logged off and tried again. Same thing, password was not accepted.
Earlier I had tried to Repair Permissions from the Utilities/Disk Utility program and had received the following:
Group differs on ./private/etc/authorization should be 80 group is 0
Permissions verification is complete.
Permissions have been verified or repaired on the selected volume.
So it would appear that if the repairs ARE being made, they don't last or are being re-corrupted. Does that make any sense?
Perhaps, but most repeating Permissions fixes can be ignored since usually it's resetting it two or more times from past updates... but not always of course, and this one seems to be quite relevant!?
You don't have another drive to install to & boot from do you?
In Finder goto /private/etc/
Do a Get Info on authorization & see if it says Owner= system R&W, Group= wheel RO, Others RO
Thanks again for your help in trying to track this down.
I do have another drive that I could possibly install to and boot from. Do you mean to do a complete Tiger install from scratch (Tiger was an update from OS X 10.1)? My other alternative is to give them a PC (which is looking like a much simpler solution at this point). ;-(
Get Info on /private/etc/authorization shows Owner = system R&W, Group=admin RO, Others RO.
There is also a file called authorization.cac in this directory and its permissions are:
Owner = system R&W, Group=admin RO, Others No Access
I don't know if this other file is relevant or not.
Those permissions seem right, but is your Tiger Install Disc the Black Retail one, or an upgrade Disc requiring 10.3 to be already installed.
We have some corruption, & may be able to track it down, but a fresah Install on another drive, or if you can afford it an Erase & install on this one would likely be faster.
Tiger install disk is Black (Mac OS X Tiger Includes Xcode 2 Install DVD).
I don't have too many options for IDE drives. Will the OS X 10.4 fit on a 4 GB (unformatted) drive? There won't be much data stored on it by its intended user. If not, I may be able to get my hands on a larger IDE drive.
This may take a while as I am leaving town for 10 days on Tuesday. I was hoping to get this sorted out before I left because I thought it would be pretty simple and straightforward. Famous last words.
To use Mac OS X 10.4 Tiger, your Macintosh needs:
* A PowerPC G3, G4, or G5 processor
* Built-in FireWire
* At least 256 MB of RAM (I recommend 1GB minimum)
* DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation
* At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools (I recommend 20GB minimum)
You can probably reduce the 3GB a bit by eliminating some Apps, LKanguages, & printer Drivers at the Cusmoxe Install step.
Found a 60 GB backup dive, did an Erase and Install and everything works fine. I was hoping to not have to do that, but I guess you were right - in the end it was the quickest solution. I had forgotten how good the Apple install is at preserving your old information. I could have kept all the old users, but due to the problems I was having, I only kept my own admin account, re-created the other user and everything sems to be great.
I really appreciate your advice and will try to pass on the favour to someone else in need of assistance.
