Running latest version of Lion on a 2010 macbook pro.

 

I ran Repair Permissions from Disk Utility, and it reported that it repaired hundreds of incorrect permissions.

I ran it again a week later, and it again reported that it repaired hundreds of incorrect permissions. So I ran it again straight away, and it again reported that those same permissions were not as they should be. So it seems that it is not repairing anything at all, despite what it says.

 

So why is it doing this, and what can I do about it? As far as I can tell, there is nothing obviously wrong with the way the computer is running. But there is obviously something wrong with the Disk utility app, and I'm concerned about whether it will work properly when I really need it to.

 

I'd be less concerned if it just said that it couldn't repair these permissions, but it is saying it repaired them when it didn't.


MacBook Pro, Mac OS X (10.7.3)

    Alwats been a bit of a question mark over what is reported in Permissions repair in DU or even Applejack. As long as it says Permissions Repaired' then they have been repaired, regardless of all the lines of text you see. You can search for further explainations on it in these forums.

     

    Personally I have found that if I do have cause to repair permissions, which is rarely, then 10.7.3 shows almost nothing compared to what Snow Leopard shows, but rest assured it means in no way that you are having or will be having any systemwide problems.

     

    Good Luck

    Thank you, but....

    If indeed they have been repaired if DU says they have been repaired, why is DU then saying, five minutes later, that the same permissions are wrong again? Something is definitely wrong somewhere. And this not just a few permissions. It is hundreds of them. A long, list that goes on and on, again and again.

    What you're seeing are most likely notifications, not errors. If they are notifications, you have nothing to worry about.

    No, they are nothing like that. They are normal permission errors and, as I said, it actually says that they have been repaired.

    I appreciate your trying to help, but it would be more constructive if you actually believed me. I am not making this up, and I have a reasonable amount of experience.

    I went into the Recovery Utilities, and tried to reset Permissions from there, via the resetpassword app. Permissions were quickly reset for all users except one. For that user, the wheel turned uselessly for three hours. There is definitely something wrong here.

    Why are you repairing permissions? What's the underlying problem?

    It's not my computer, but apparently it was "acting strangely". Not being able to open files, that sort of thing. I was all set to say to **** with it, but then I found out that even in recovery mode, it will not reset that one user's permissions. That concerns me because it is not acting as it should, and there is no apparent reason.

    Repairing permissions, though immensely popular, is a complete waste of time unless you have a specific indication of a permission error involving system files, which is rare, or a boot failure. It always spews bogus warnings that mean absolutely nothing.

     

    If you're unable to reset the permissions of a user home directory, it may be because there are locked files in that directory. Enter the following shell command as the user in question:

     

    chflags -R nouchg nouappnd ~

    Thanks.

    I get the message back:

    nouappnd - no such file or directory.

     

    Sorry, I don't know much unix.Do you mean noappend? I'd try, but ...

     

    (Yes, I have always thought that repairing permissions is over-rated. However, I don't like it when something is clearly not working properly and I don't know why. I'd rather fix it now rather than risk trouble further down the road).

    My mistake. That should be

     

    chflags -R nouchg,nouappnd ~

    Thanks. Permissions are now reset.

    There are lots of people on these pages with a similar 'problem', so I hope they see this.
