    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!

    If repairing permissions results in error messages, some of these messages can be ignored and should be no cause for concern.

    Some people repair, or recommend repairing permissions for situations where it isn't appropriate. Repairing permissions only addresses very specific issues. It is not a "cure all" or a general performance enhancer, and doesn't need to be done on a regular basis. It also doesn't address permissions problems with your files or 3rd party apps.

    There are times when repairing permissions is appropriate. To do so, here are the instructions:

    Thanks again
    afew of the links dont seem to work unfortunately

    anyway going back to the first link u posted i checked my permission errors to the ones in the logs apple described they are very simlar but are not mentioned these are my permission errors

    Verifying permissions for “Macintosh HD”

    Permissions differ on “System/Library/CoreServices/Menu Extras/”; should be drwxr-xr-x ; they are lrwxr-xr-x .

    Permissions differ on “System/Library/MonitorPanels/Arrange.monitorPanel”; should be drwxr-xr-x ; they are lrwxr-xr-x .

    Permissions differ on “System/Library/MonitorPanels/Display.monitorPanel”; should be drwxr-xr-x ; they are lrwxr-xr-x .

    Permissions differ on “System/Library/MonitorPanels/Profile.monitorPanel”; should be drwxr-xr-x ; they are lrwxr-xr-x .

    Permissions differ on “System/Library/PreferencePanes/Displays.prefPane”; should be drwxr-xr-x ; they are lrwxr-xr-x .""""""

    i dont no whether this is a cause for concern as thiese exact permission errors dont seemed to be mentioned in the article?

    any help would greatly be appreciated..

    Thanks for the heads up on that. It would be nice if they'd stop changing their sites and breaking links. The MacWorld article seems to have disappeared.

    Do you have a specific problem you're trying to resolve? If not, I wouldn't recommend repairing permissions or worrying about those errors. Repairing permissions isn't the first thing you should be doing if you're experiencing slow performance. Neither is resetting NVRAM/PRAM. Both procedures should be used only when addressing a particular issue that they relate to.

    If you're having performance issues, this may help:

    I get this when I run the stuffs on disk utility. Like the other person said, it repaired it successfully but there are still errors on it when you run it again. This errors seems to be preventing me from installing mountain lion. I've been having problems installing mountain lion.

    Thanks ggj the main problem im having id say is i mainly use this system for djaying only i use a program called serato

    i have hooked up an external hfs wd macbook external 2tb firewire 800 drive

    while analysing files via the program it used to be incredible quick, now it has become painfully slow, , so i tried to fix the permission of the hard disk of the c drive

    the drive in question isaround 6 months old around 75% full and has had a lot of files constantly moved between the drrive

    also with me coming from windows what id have down to fix this would be to defrag this external drive, do u recommend that? and if so what program would you recommend to defrag the external drive only?

    going a bit off topic here.

    also with this mac having the recovery partion on the hd, i was unable to do a clean wipe of the boot drive, the other month i did a complete reinstall, , comand r, and erased the partion it let me, but it wouldnt let me delete the recovery partion i assume this is normal?

    i then recreated the partition that it let me erase and reinstalled osx, to be honest i have about 6 -10 programs installed on it, and im a bit ocd ish about this permission stuff so i might reinstall osx later this week,

    out of curiosty if i was to reinstall osx would it fix this permission issue?? and i assume its not bad becasue its very similar toi the issue detailed in the apple article, also the problem is the issue may arise again?

    ive done it a couple of time now, but im wondering are there any decent guide i can correspond to regarding the internet recovery partition?

    I assume you mean your internal boot drive, since there is no "C" drive in Mac OS X. As the links I posted earlier show, repairing permissions doesn't affect user files on your internal or external drive, so that won't help.
    No, you don't need to defrag drives in Mac OS X, except possibly when partitioning a drive.

    Yes, since Mac OS X Lion and Mountain Lion don't ship with an install DVD, the recovery partition serves that purpose. If you need to do a clean reinstall of your OS, you would use the recovery partition.

    No, because many of those repair permissions errors will always occur and should be ignored. You shouldn't need to repair permissions at all, except in specific circumstances where doing so addresses a particular problem. Repairing permissions isn't a general "fix it" or performance enhancement tool.

    thanks very much for the ggjstudios sorry about the delayed reply i have been unwell

    im sorry i wasnt refering to the cdrive, its the external wd my book studio drive (its an aluminum western digial drive designed for mac) 2tb firewire 800

    the drive just seems incredible slow, but its only six months only,

    now i now its probably not worth defragging the drive having to buy a program to do that,

    im not sure why this drive would become so slow? when browsing through a folder full of pictures it takes time to even display previews!

    so im not sure, do u have any suggestions why it could become so slow?

    is there maybe a setting that may have have disabled the full speed of the firewire 800?

    would i be best backing up the content of the drive to a nother external drive i have then formating it again ( i assume reformatting it will reduce a need for defragging anyway, or so i bassically read?)

    and then simply copy and paste my file back to it once reformatted?

    again i really appreciate all your help , i was concerned about the permissions, but looking in to it the mac does repair but when rescaning it finds the same faults again, i suppose if they were serious they wouldnt be repaired in the first place, even tho technically there not properly getting repaired, i assume i would be notified if it was a major problem
