    The OSX install blue screen blues

    This problem is really making me feel the blues!

    I have a Power Mac G4 with Mac OS version 10.2.3. This has been working fine for me for over a year. 2 weeks ago for some inexplicable reason I decided to update this software. My mac is not connected to the internet so I downloaded the updates via my pc and burned them on to a cd. I then updated the mac from the cd. This is when my problems started. The upgrade installation did not complete and left the computer hanging. I tried to re-install from the original cd but it would not upgrade a newer version of the software (obviously duh!). I tried various other things but eventually decided to cut my losses and did a clean re-install of the os 10.2.3. It took 17 attempts and many blue screens before it installed. But I could not get past the blue screen.

    That was 2 weeks ago. Yesterday I decided to try all over again, being very careful at every step. I wiped the disk and then did a clean install, but left out all the additional stuff like printer drivers, languages additional applications etc (it still took 3 attempts before it installed). But, guess what I still have the blue screen syndrome. When I boot up it goes through all its processes, looking like its loading up the firewall etc etc but then hangs on a blue screen, sometimes flickering a bit.

    I have tried to boot up in Safe Mode but it just does the same.

    I have removed all peripherals except the screen, mouse and keyboard (this was done before installing the os 10.2.3)

    I have also tried all of the following:

    Selecting the "Connect automatically when starting TCP/IP applications" option in Network preferences can sometimes cause this issue. You'll need to delete the preference file that holds this setting. This is an advanced step that will reset all of your computer's network settings. You will need to reconfigure them in Network preferences to reconnect to the Internet or a network.
    Start up the computer in Single-User Mode.
    Type: mount -uw /
    Press Return.
    Type one of the following:

    (for Mac OS X 10.2.8 or earlier)
    mv /var/db/SystemConfiguration/preferences.xml preferences.old

    Press Return.
    Type: reboot
    Press Return.

    If your computer still starts up to a blue screen, follow these steps.
    Start up the computer in Single-User Mode.
    Type: mount -uw /
    Press Return.
    mv /Library/Preferences/ preferences2.old

    Tip: There is a space between ".plist" and "preferences".

    Press Return.
    mv /Library/Preferences/ preferences3.old

    Press Return.
    Type: reboot
    Press Return.

    Reset certain privileges.
    Start up the computer in Single-User Mode.
    Check the volume with fsck.
    Type: mount -uw /
    Press Return.
    Type: chmod 1775 /
    Press Return.
    Type: reboot
    Press Return.

    I tried to do this but could not work out how (I did not create a username):

    Start up the computer in Single-User Mode.
    Check the volume with fsck.
    Press Return.
    Type: mount -uw /
    Press Return.
    Type: cd /Users/[affected username]/Library

    Tip: Instead of "[affected username]", type the username for your account, or the account that is experiencing this issue. For example, if the username is "theta," type:
    cd /Users/theta/Library

    Press Return.
    Type: mv Preferences Preferences_old

    Press Return.

    Type: mv Caches Caches_old

    Press Return.
    Type: reboot
    Press Return.

    I also tried the suggestions in this forum including:

    Repair Disk Permissions - Go to Applications|Utilities|Disk Utility and select repair disk permissions on your OS X drive

    2) File System Check - When booting up your computer hold down the Apple Key & the S key and it will boot into single user mode. When the text is done loading on the screen type in /sbin/fsck -f and hit enter.
    When that is done if it fixed things then do the check again to make sure it is cleared
    When finished with that type in exit and it will start the computer in normal mode

    I also tried these 2 things bit it just went in to non existent Safe Mode:

    5) Resetting the PRAM: When booting, hold down Command-Option-P-R and wait for the triple startup chimes.

    6) Reset Nonvolatile Firmware: When booting, hold down Command-Option-O-F and wait for the command prompt. Type "reset-nvram" and hit enter.

    And I could not work out how to do the following suggestion (where does one delet preferences or caches):

    3) If it is a particular program that is giving you problems delete its preferences in 'Your User Name'/Library/Preferences

    4) Clean Your Caches - Delete everything in the folders Library/Caches and in Users/*Your User Name*/Library/Caches. When finished reboot.

    Oh and I have also run Alsofts' Diskwarrior to no avail.

    As stated earlier I have been at this for over 2 weeks now. Please can someone help me sort it out.

    Thanks a lot.

    I know the last thread is pretty long, sorry for that. Still if you have any ideas to post for me to try I would really appreciate it.

    If you cannot help with the bulk of my problem perhaps you could do an easy 'how to' guide on the following:

    - deleting its preferences in 'Your User Name'/Library/Preferences

    - Cleaning my Caches - Delete everything in the folders Library/Caches and in Users/*Your User Name*/Library/Caches. When finished reboot.

    And maybe you know the answer to why I cant even boot up in safe mode.

    One thing I'd suggest is check the syslog at /var/log/system.log. You can do this by booting into single user, mounting volume, and type

    less /var/log/system.log

    Navigating in less is pretty simple. spacebar to page down, 'b' to page up, 'G' to th end of the file. Look at the man page for less for the details.

    Each entries have time stamps. By looking at the time stamp continuity you can kinda tell the last entry during the last failed boot up. That might give you an idea why it fails to boot.

    Thanks for that Molt. I tried what you suggested but the info did not mean much to me - too much for a newbie like me!

    One thing that I noticed was that it said that it could not alloc class NVDANV20HAL when going in to single user.

    Any other ideas for me to try folks or do I just give up on macs and go back to my PC for everything.

    Here is what I would like to ask:

    What version of the OS were you trying to upgrade to?

    Did you use the combo update?

    Are you sure the update you downloaded with your PC is any good (maybe be corrupted due to a PC down load)?

    What OS level is the original media you have (is it a complete 10.2.3 revision)?

    Can you boot up in OS 9?

    Regarding syslog error message: You don't have to make sense out of error messages yourself. Once you have found the error message you can search google for possible remedies or call tech support and ask.

    Hey Dave... I have a couple of questions for you.

    1. First tell us what are you trying to do??
    As I read your thread and get really confused.

    2. Why are you using the terminal for installation?
    It's not a PC, so there's no need to touch the terminal, what so ever!

    3. After installing Jaguar 10.2.3, what version are you trying to upgrade to? Latest version maybe? Well in that case, you need to buy Panther, as it's considered a Milestone upgrade. And if you attempt to upgrade Jaguar 10.2.3 to Panther 10.3.0 you gonna get more problems than it's worth. The two versions have so many differences between them.

    4. Why make things more complicated for yourself?

    FYi: Downloading patches with your PC for installation to a Mac isn't recommended. The Mac OS uses resource folks and nearly all PC burning software will lose them. Although the files appears to be all there! They maybe missing some vital information.

    If your Mac isn't online but have a router for your internet connection. You can simply attach a network cable to the router or if you have a Network card in your PC. Or network your Mac to you PC and download what ever you need.

    To install the operating system from CD/DVD on a Mac is a really simple process.
    Just follow those steps, the whole thing should take 20-40 mins.

    Installing/Reinstalling the OS from CD/DVD

    1. Insert the Mac OS X Install Disc 1 CD and double-click the Install Mac OS X icon.
    2. Follow the onscreen instructions. In the panel where you select the destination disk, select your current Mac OS X disk (in most cases, it will be the only one available).
    3. Click Options. If you want to save your existing files, users, and network settings, select "Archive and Install," then select Preserve Users and Network Settings. If you want to erase everything on your computer and reinstall Mac OS X, select "Erase and Install." You can't recover erased data.
    4. Click Continue.
    5. Click Customize to select which parts of Mac OS X you'd like to install, or click Install to perform a basic installation (recommended).

    If you purchased a standalone version of Mac OS X, these installation instructions are in a booklet included with Mac OS X.

    To start up in Safe Mode for debugin, just do the following. Not required for most users.

    Starting up in Safe Mode - For alll versions of Mac OS9 and OSX

    1. Shut down the computer.
    2. Press the Power button.
    3. Immediately after you hear the startup tone, press and hold the Shift key.
    4. Release the Shift key when the spinning progress indicator appears below the gray apple on the screen.

    To leave Safe Mode, restart the computer normally.

    And for adding new users to your system. It's only a few clicks away.
    And you don't need the terminal and any commands, just use the GUI.

    [bAdding a new user account to your computer[/b]

    1. Choose Apple menu > System Preferences and click Accounts.
    2. If some settings are dimmed, click the lock icon and type an administrator name and password.
    3. Click Add (+) and type the user's name.
    4. Type a short name if you don't want to use the short name generated automatically. (Once the account is created, you won't be able to change the short name.)
    5. Type the user's password in the Password and Verify boxes.
    6. Type a hint to help the user remember the password if they have trouble remembering it at login.
    7. Click Limitations and select options to determine what the user can do with the computer.

    If you change your mind while you're creating a new user account, click Delete (-) to cancel.
    Good Luck

    Thank you for the responses and apologies that my post is a little confusing.

    I have still been unable to sort out the blue screen business with my version of os 10.2.3 so I have bought a new set of cd's: os 10.3

    I am now having problems installing this new version and am starting to get paranoid that Macs just do not like me!!

    Error messages include:
    root: bootstrap_look_up(): unknown error code
    ERROR:Could not read archive file. - pax: invalid header
    ERROR:Could not write file. - pax: WARNING! These patterns were not matched


    Can't open package /Volumes/Macintosh HD/Library/Receipts/BaseSystem.pkg (there was an error reading the file

    I have cleaned install cd.
    I have run disk utility and repaired permissions and rapaired disk (there were no errors)
    I have run fsck in single user (no errors)
    I have run Alsoft diskwarrior (no errors)

    So to summarise: I am trying to install os 10.3 but it keeps not completing and telling me that the install failed and to restart and try again.

    Im not much help here but have you tried taking it to apple and seeing if they could do it for you? Even if the warranty has expired I think it would still be worth the extra money to have them fix it for you
