Need to restore disk permissions? help!

I kept having problems opening files, with the system saying it was "locked" and could only open read-only. So i changed the permissions on my HD to "read & write" for all enclosed items.... BAD MOVE. Now I have a mess.
Extenstions won't load etc. So I repaired permissions, from boot disk and from disk utility when booted from drive. Changed the permissions back on some things manually when comparing to another drive. But It would take forever to compare every file. I've reinstalled Lion once and that didn't help at all, same error messages.
Is there a way to restore the System and Library folder and all of the items enclosed in them to the "Defaults"? Because now the computer is slow too.
I have a macbook pro 17" mid 2010 version with 8gb ram.

You've basically hosed your whole system.  Repairing permissions with Disk Utility will fix some of that, but not all of it.  Honestly, if I were you, I'd erase the drive, reinstall the system from scratch, reinstall all your apps from scratch and then restore your documents from a backup (preferably a backup made before you changed all the permissions).  If you have a backup of the whole system from before you changed the permissions, that would provide you an easier route.

  • Repair disk permissions help

    Hello all,
    im fairly new to the macbook and have been reading up on repairing disk permissions as the mac has started to slow down in time
    the problem i have is i opened disk utility
    and ran verrify disk permisions, it found problems, so i restarted and held comand and r and booted into the recovery console
    from there, i chose disk utilities and ran verify disk again, again it found problems, so i ran repair disk permisons, that came  back and repaired succefull,
    so just to check i then vefried the permisons again, and once again it found the same problems, so i then re - repaired the permisions, and again it cam back succefull
    again i double checked and once again it found the same problems , so im going round in a loop here the problems arnt actually properly fixing?
    how can i sort this out?
    any help would be appreciated!
    regards

    Those messages are in fact quite similar to the ones Apple mention in the KB.
    All the examples you posted are instances of the same symptom: the BOM states a given path is supposed to be a directory but it actually is a symlink to a directory.
    A possible cause of this is when something was installed that did not foresee upgrades that would leave multiple versions installed at the same time, then the development team eventually decided that a new version would be needed to co-exist with the old one and such a new version has been installed. The old BOM file still report the directories (or files) as not being symlinks but the new installation actually moved the old data to a directory specific for the old version, installed a new version and then changed the old directory (aka the "unversioned" or "current" path) to a symlink to the latest installation.
    You can safely ignore these differences.
    While in the past running permission repair used to be a very important periodic maintenance routine, nowadays it's rarely needed and even more rarely useful. It still is a good idea to run it right before and after an important operating system patch update, but it's not really necessary.
    It's very common (and has been for a long time) for the tool to report differences, say they have been repaired, and then, if run again, to report the same differences. In those cases you can generally ignore those differences. Only if the repair tool says it failed to repair something you should be concerned.

  • Itunes locks up, and I need to repair disk permissions.

    Itunes locks up on my Imac after it has been running for a while. I have had to repair disk permissions, which show many Itunes corrections are needed. I am running the latest Itunes.

    Disable Photo Stream in iPhoto's preferences and then go back and reenable it. See if that will jump start the process.  If that doesn't help try this:  make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
    1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
         User/Home()/Library/ Preferences folder.
    2 - delete iPhoto's cache file, Cache.db, that is located in your
         User/Home()/Library/Caches/com.apple.iPhoto folder. 
    Click to view full size
    3 - launch iPhoto check its preferences to meka sure all is as you expect and try again.
    NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
    NOTE 2:  In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

  • Need to Repair Disk Permissions Everyday? Same errors each time.

    I have a White MacBook 4,1 - 2.1 Ghz 3 MB Cache, 800 MHz Bus. It seems like I need to repair the permissions everyday. Every time I do I get the exact same errors, when I start up off the Mac OS X dvd I get no errors under repair disk, but the same errors under repair permissions.

    Permissions repair complete
    Anyone know what's wrong?

    There is no error. You could repair permissions continuously and these same notifications will show up.
    Recent updates to iPhoto, Front Row, and an update for RAW compatibility have resulted in these permissions differences. Rather than replacing the old permissions with a new one, the system sees a symbolic "link" (the L you see in front of the permissions).
    Nothing is wrong with your machine--we're all getting these notifications. Hopefully a system update will change the permissions for us in the future.

  • HT1353 i have aclassic 120 gb 2nd edition and i need to restore the setings. help

    i need to restore my ipod settings so i can resysnc all my music

    Yes, when you restore as new everything will be wipe from your phone.
    You will need to sync with itunes http://support.apple.com/kb/HT1386  to get back your apps/music and contacts IF you sync with a program in itunes.
    I suggest you import your pics to your computer http://support.apple.com/kb/HT4083  then after you restore your phone, you can sync it back to your phone.

  • Trying to connect to iTunes but says i need to restore iphone!  HELP!

    A few month ago my pc's hard drive crashed. I have since got it fixed with a new hard drive and with Windows 7 (previously I had XP).
    I have just downloaded the new version of iTunes and when I connect my iphone a pop up appears stating that iTunes cannot read the content of my iphone and that it needs to be restored to the factory settings.
    Is there anyway of fixing this problem without having to restore my iphone? If there is no alternative is there a way of saving everything? I haven't done a back up or upgrade in oer 4 months.
    Your help is much appreciated. Thanks

    Unfortunately, no. If iTunes is giving you that message, there is data or code seriously corrupted in your phone, or there is hardware damage. The only solution is to restore as instructed. This is the downside of not backing up.
    Out of curiosity, why did you not install iTunes and backup right after you replaced your HD and OS on your computer?
    The only alternative for saving some data (the backup) is to obtain a 3rd party app for windows that can backup and restore some of it independently of iTunes. There are several of these - Google is your friend to find them. The caveat is that if your iPhone flash drive is corrupted, those apps may not work properly either.

  • Disk permissions - help!

    Hi -
    I hope someone can help with this. I had Carbon Copy Cloner crash while doing a clone, and since then my permissions have been really screwy. I wouldn't worry - I know a lot of people seem to think fixing permissions are basically voodoo half the time - but this really does seemed to have caused a problem because...
    a) If I try to fix permissions using Disk Utility it exits almost immediately with an error: "The underlying task reported failure on exit". Ditto if I try to verify the disk (though fsck said everything was fine).
    b) If I try to do anything involving Apple's installer (and a couple of other things like FileMaker Pro) I get permissions-related failure reports. I've got to the stage of downloading the 10.5.1 update to try to re-install it over my current 10.5.1 installation, but can't... because the installer quits out.
    Any advice on how to fix this would be gratefully received! I'm not certain CCC caused the issue (I have a vague memory of an installer issue prior to all this) but it's certainly worse since then...
    Michael

    Hey -
    Thanks for your reply... I did have Time Machine running since day one, but then I had to use a new Firewire drive for it, and since then have never been able to get Time Machine to recognise the new disk (keeps failing with volume couldn't be found errors) despite erasing, partitioning, re-erasing and what-all else about ten times...
    And now I have the issue with the permissions, which I don't seem to be able to find any way to fix...

  • Restored to factory settings, Recovery mode, need to restore?? HELP!

    When I connected my phone to my iTunes on my computer to do the update to iOS 7.0.4 (I think...) it said it needed to be restored to factory settings to complete the update. I clicked on it to restore, and it did the restore. It said it was restored to factory settings and it would have to restart to complete the restoration. It says not to disconnect it. Then that message disappears and a new message appears saying "iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes." And I'm not sure what to do, because I have tried to restore it three times and it just keeps saying the same thing. Also, when the message comes up that it has been restored and to not disconnect it, my phone screen changes to a USB cord with an arrow pointing to the iTunes symbol like it has been disconnected but the USB is still connected. Help!!!

  • My computer (windows XP) nor itunes is recognizing my 4g Ipod touch and I need to restore it. please help...

    So today I decided to change my Itouch password. After realizing the code was an awkward movement for my fingers I changed it to something easier. HOWEVER I ended up forgetting the code and locking myself out. I then learned I had to recover my ipod, which I wasn't to worried about thanks to iCloud, but my computer nor itunes will recognize it. I usually do all my itunes stuff on my friends computer and I already did the msconfig thingy. Please help, i"ve been at this since 8:00 pm

    If your iPod Touch does not have volume buttons on the left side then it is a first generation and iOS 3.1.3 is as far as you can go.  If tou have volume buttons, you can go higher using iTunes,

  • Power Mac G4 no iMovie and no restore disk

    I purchased a used Power Mac G4.  It is running OS 10.4
    The problem is that it does not have iMovie installed.  Online help states that I need the restore disk, which I don't have.  Is there a way to get it, or is there another alternative?
    The other problem is that updating the software requires a password from the former owner.  The machine boots to desktop without a password, it's just needed for updating Safari.  Is there a way to reset that?
    The machine is in other wise fine shape and I'd like to make it useful.
    Thanks,
    Jay

    If you are in the US call Apple Customer Support 1-800-767-2775, provide the Serial Number and specifications of the Mac, and for a reasonable fee, they will supply a replacement set of system discs (if available).
    The discs will be for the original version of the OS that was pre-installed when the Mac was manufactured.
    If you are in another country:
    http://support.apple.com/kb/HE57
    Have you asked the vendor for the password?
    iMovie is part of iLife. You should be able to purchase the relavent version on eBay or Amazon.

  • Disk Utility Repair Disk Permissions now Documents folder is empty

    After having trouble downloading a file (error message said disk was full but I had 12g free) I decided to try the 'Verify Disk' and then 'Restore Disk Permissions' actions in the Disk Utility application.
    Now my 'Documents' folder is empty! No disk space has been freed up so I believe the files should still be there, I just can't see them. When I choose the 'Get Info' action on the 'Documents' folder it says 0 files.

  • Re: Satellite L300-18D - How can I get a Vista Restore disk?

    Hi everyone
    My laptop (Satellite L300-18D) was seriously infected by viruses, everything corrupted. I need to resinstall Vista but don't have the restore disk. After searching around I managd to download a restore disk from some site, but when I used this disk, it gave me an error code which meant the product key was wrong. I used the product key from the bottom of the laptop (I trust this is an OEM). So I guess I need a restore disk that will work with my OEM product key.
    How can I get this restore disk that will work with my OEM licence?
    Also, I tried to install XP on my laptop, but it kept giving me a message saying it could not detect the hard disk, there is nothing wrong with the hard disk, I have tested it on another laptop. Is there any sort of barrier o installing XP on this laptop which came with Vista originally. Is there a security meassure somewhere that stoped me from installing XP?
    Thanks in advance

I had a hard time getting it to boot up, but finally did using a Mac OSX Leapord DVD that I have.  It would not boot from the original disk that came with the iMac as it would just keep ejecting it when I would try to boot from it.
    I've run all the updates and want to install Snow Leapord, but it won't let me.  Keeps giving me kernal panics about 3/4 of the way through the install.  I thought maybe I need to check disk permissions, but when I got into the DU, the permissions buttons are greyed out.  When COMMAND-I to get info, it says (don't remember the exact words) "Repair Permissions:  NO
