I've deleted Wheel in Macintosh HD permissions and now I receive a blue screen at Start up

Details:
Mac Book Pro
Snow Leopard OSX 10.6.8
Problem:
I was looking at Macintosh HD (ctrl-i) and saw "wheel" under permissions.
I foolishly deleted "Wheel" (command delete) from permissions.
I got the processing icon aka beach ball.
I may have clicked something in frustration because Color (Adobe?) popped up. This may be nothing.
I tried to force quit (command-option-esc), no luck.
I held power button down, computer shuts off, I wait, I turn on.
The apple and gray screen with loading symbol (gear) then blue screen with loading symbol followed by light blue screen.
Blue then lightblue repeats.
What I've tried:
I try loading in safe mode. (shift)
Blue Screen.
Restarting (command+p+r and other).
Blue Screen.
Using 10.5.4 install disk > Disk Utility > Hard Drive permissions Check, Verify, Repair.
Blue Screen.
Also Change password > reset ACLs etc. first Macintosh HD, then Root.
Blue Screen.
I tried using a small external HD and booted from 10.5.4, tried updating to 10.6 but no.
I don't have Snow Lepord. No backups (2T external died).
Anyway to just replace the OS and keep my data without 10.6.X disk and not have to backup and install down to 10.5?
Your help is greatly appreciated. Thanks.

    Yeah it works fine over wifi the problem is when I try to use it over my 3G. It's really stressing me out now.

    In preferences turn on iTunes sharing in iTunes preferences and keep iTunes turned on in both accounts. Or better yet put the iTunes library on the main HD rather than in an account and set the location of the library to that location in iTunes preferences.

  • I manually deleted back-ups from Time Machine and now I can't empty the trash

    I manually deleted back-ups from Time Machine and now I can't empty the trash.

    Using Finder (deleting Time Machine backups) to manage Time Machine files is a mistake. The remedy is somewhat easy, but you will lose all the files on that TM drive.
    If there is nothing elese on the Time Machine drive, try reformatting the drive with Disk Utility. This will effectively remove the files from that drive from the trash. If you have files on this drive, temporarily copy the files to another drive, then reformat the TM drive.

    You'll have to restore them from the most recent backup you made before you deleted them.
    When computers and iOS devices are "synced" together, whatever you do on one device is synced to the others. You deleting them off your Dads phone made the same occur on your phone. That's how it is supposed to work.

  • I erased my ipod in the setting because i wanted to restore my ipod and someone told me to delete it so i did and now its just a black screen and when i plug it in my pc it doesntt show up

    Connect the iPod to a charging source and then try the will not turn on topic of:
    iPod touch: Hardware troubleshooting
    If you have a 2G iPod and did not have the iPod connected to a charging source it is likely that the battery fully drained before the erase was complete since it can take hours to do the delete.

    Welcome to the Apple Community.
    Do you have a back up taken prior to deleting them.
    To restore from a back up made through iTunes, follow these instructions.
    To restore from a back up made through iCloud, try the following:
    The difficulty in restoring iCloud data from a back up is that the back up is older than the current version on iCloud and anything that is restored gets removed again when an iCloud sync occurs.
    Ensure the device is connected to your local network.
    Start the restore from iCloud back up.
    Allow the devices settings to restore (watch for the confirmation of completion).
    As the apps begin to restore pull the connection to your router WAN port (the one that goes to the telephone point).
    Wait for the time out confirmation.
    Navigate to settings > iCloud and turn off contact syncing (keep contacts when prompted).
    Reconnect the router to the internet and let the restore process complete.
    Delete any iCloud contacts from iCloud.com on a computer.
    Navigate to settings > iCloud and turn on contact syncing (merge contacts when prompted).
    May I suggest that you carry out a back up to iTunes before you try anything, that way should things become even worse, you can at least restore back to where you are now.

  • Blue screen on start up.  The wheel spin and the blue screen gets brighter for a second, then the blue screen dims and it repeats with the wheel.

    When I start up my imac, I get a blue screen.  The wheel spin and the screen gets brighter for a second, then the blue screen dims and it repeats with the wheel.

    Are you referring to the startup screen which is normally gray with the dark gray Apple logo or are you referring the login screen which is typically blue? If it's the latter you might give this a try:
    Clearing Caches to Fix Login Problem
    You will need to type some Unix commands. If you are not comfortable with this, I don't know of anything other than a re-install. But if you are careful, you should be OK. I recommend you print this out in a largish mono-spaced font so you don't miss any spaces (or add extra ones). Note that case is important.
    Be careful. Some of these commands are dangerous, since you are going to be root.
    Start up in Single-user Mode. When this has finished you will see a prompt ending in '#', although there may be other messages. Enter the following commands after the prompt:
    /sbin/fsck -fy
    Press RETURN. Wait a few seconds for 8-10 lines of output. If the last line says repairs were carried out, repeat this command until you get a message 'The volume <yourdiskname> appears to be OK'. Then continue with:
    /sbin/mount -uw /
    cd /Library/Preferences
    rm com.apple.loginwindow.plist
    rm com.apple.windowserver.plist
    cd /Library/Caches
    rm -r *
    cd /System/Library
    cd /System/Library/Caches
    rm -r *
    reboot
    Press RETURN after each command.
    This should now take you to a proper login screen after the normal boot sequence. You should then Repair Permissions by using Disk Utility (in your /Applications/Utilities folder).
    If it's the former then reinstall OS X. For Snow Leopard:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

  • Deleted Items from Hard Drive folder and now nothing works ...

    Hi All,
    Under the 'Search For' heading in the right hand column of the grey box that comes up when you open your hard drive, there are the heading All Images, All Movies, All Docs .... I've deleted about 2600 files from the 'All Images' folder and now my iPhoto won't open as there is nothing in it, and my Entourage crashes when I try to open it.
    I've obviously deleted files that were needed for these applications. The items are all still in my Trash, but I don't know how to return the files to their original homes. Can anyone help please?
    Thank you

    V.K. - thank you for your help. I've manually moved all my photos back to iPhoto and that's back up and running.
    The problem I'm left with is how to reinstate the correct files to Entourage. Even if I could identify which files are part of that application (can anyone help with that?), I'm still not sure how to put them back into Entourage. Is it simply a matter of dragging them over to my Entourage icon?

  • Upon start up I get a start up disk full message and to delete files, now I only get a a blue screen on start up. How to I get past the blue screen and how do I delete files?

    Upon start up I get a "start up disk full message, delete files". Now on startup I only get a blue screen. How do I get past the blue screen and how do I delete files.

    That;s really not enough free space... you can use a tools such as OmniDiskSweeper to find out where your large files reside and begin pruning (or copying to an external if they're files that you want to keep).
    One thing is certain - if you're going to continue your current usage you're certainly going to need to install a larger boot drive.
