Cannot repair permissions

Hello,

I cannot repair permissions using Disk Utility. The buttons to repair or to verify the permissions are not enabled. I've tried to boot from the orginal disk system to try the operation again but I still have the same problem because I cannot click on the buttons.

I need to repair my permissions because I cannot start the Activity Monitor.

Onyx is unable to repair either because it gets stuck.

What should I do?

Hi, Pierre.

I presume you are trying to repair permissions on your normal startup disk. The Verify/Repair Disk Permissions buttons are only available if you have selected a volume in the left column of Disk Utility that contains Mac OS X, e.g. the volume Macintosh HD.

1. Is your Macintosh HD > Library > Receipts folder (/Library/Receipts directory) extant?

2. Try the following:
2.1. Startup from your normal startup disk.

2.2. Launch Terminal, which is in the Macintosh HD > Applications > Utilities folder.

2.3. At the Terminal prompt, type the following command exactly as written:

sudo diskutil repairPermissions /

then press Return.

2.4. When prompted, type your Admin password and press Return.

2.5. If the command fails, copy and paste the output from such into a reply here.
3. Before attempting to repair permissions, try Steps 1 and 2 of my "Resolving Disk, Permission, and Cache Corruption" FAQ. Let's make sure you hard drive and its directory are AOK.

Good luck!

Hello Dr. Smoke,

I bought a new drive recently. So I decided to partition this new drive. As you said: "The Verify/Repair Disk Permissions buttons are only available if you have selected a volume in the left column of Disk Utility that contains Mac OS X, e.g. the volume Macintosh HD." I was unaware to this fact. Knowing that, I was able to use 'Disk Utility' properly. Thank you.

But I was still having problems. I made the discovery that the 'Get Info' window for my volumes were having the check box 'Ignore permissions' checked. So I unchecked the boxes after that. I was finally able to repair 'Activity Monitor' using 'Disk Utility' again.

Now, I have 'Activity Monitor' running but no process is listed at all. While I'm writing this message, I am sure my computer is ON. 😉 'Activity Monitor' is showing that the CPU is busy, that I have 0 memory, that I have no disk activity and that I have no network activity either.

'Top', the unix tool, is running well. Everything is running well on my computer but not 'Activity Monitor'.

Any idea?

1. Have you tried restarting your Mac since you repaired permissions?

2. What's selected in the pop-up menu in the Activity Monitor toolbar? What if you select "All processes"?

3. Quit Activity Monitor if it is open. Then trash the com.apple.ActivityMonitor.plist file in your Home > Library > Preferences folder. Then relaunch Activity Monitor.

4. If none of the above help, immediately after launching Activity Monitor, check these Console logs for clues.

Good luck!

After Update to 10.4.6 the disk utility on my system quits unexpectly after selecting any volume.

I´ve copied the old disk utility (from 10.4.5) to help it. Repairing disk permission is working with this one...

Anyway, does somebody have any suggestions what could be the problem with "not working disk utility" under 10.4.6?

Best regards

Mike

1. Have you tried restarting your
Mac since you repaired permissions?


Yes.
2. What's selected in the pop-up menu in the Activity
Monitor toolbar? What if you select "All
processes"?


Yes. Playing with the menu, the search field and resizing the window does nothing. I see nothing listed.

3. Quit Activity Monitor if it is open. Then trash
the com.apple.ActivityMonitor.plist file in
your Home > Library > Preferences folder. Then
relaunch Activity Monitor.


It did that. Nothing...

4. If none of the above help, immediately after
launching Activity Monitor, c
heck these Console logs for clues.


It does not help. I see no message related to the Activity Monitor in both logs.

Good luck!


Yes, I need it badly!

4. Re: Checking Console logs. What about messages related to pmTool? This is the helper process for Activity Monitor.

5. Have you disabled any fonts?

6. Does System Profiler work OK?

7. You could try reinstalling Activity Monitor from your Mac OS X v10.4 Tiger Install disc using the shareware application Pacifist. Pacifist has excellent documentation, so you should have no problems with it.

Since Activity Monitor has been updated since it was first shipped on the Install discs, you would then also need to reapply the most recent Mac OS X Combo Update corresponding to the version of Mac OS X you have installed in order to pick up all other changes made to Activity Monitor since it was first released.

Good luck!

I found a solution to my Problem Dr. Smoke.

I am able to use Activity Monitor if I copy the application at the root of my startup disk! 🙂

I must fix the permissions of pmTool right after the copy so the tool can run as root.

It seems that this application can only run from the startup disk. My Applications folder is on another drive.

Thank you.

You're welcome.

That was a very critical piece of information you omitted. Next time you report a problem, you need to note that as part of the information. We wasted a lot of time...

It is also not the recommended way to run Mac OS X. You may run into significant problems with Software Updates if the Apple-provided applications are not in their expected places in /Applications or /Applications/Utilities.

Good luck!

It is always easier to say that after the problem as been solved. I did not know this in the first place. If I had known, I would not have written about the subject at all.

Well, I've created a symbolic link for this purpose. So my applications are in /Applications.

Installers are sometimes deleting my symbolic link and they replace it with a real folder. So I have to make the fix manually.

I also have sub folders in the Applications folder to class my applications by categories. Again, Apple System Updater is having a problem with this because it does not dig the folder hierarchy to find where my applications are located.

I consider that I'm right to do so and that Apple is wrong. I wrote about this so Apple can improve Mac OS X. If an operating system is not flexible enough, it is wort-less.

Well, had I known you had moved /Applications from the start, I would have immediately suggested moving it, or at least Activity Monitor, back. You've hacked your system and that needs to be stated before you request help you with a problem. All we can assume here when answering questions is that people are using the system as shipped. We're not clairvoyant. If you've made changes from standard, then you need to state that up front.

Then you should consider it worthless because Apple has been standardizing many aspects of the OS, e.g. Home folders, /Applications, /Applications/Utilities and is not going to change those. Software Update expects the /Applications and /Applications/Utilities folders to be on the startup disk and to contain the associated Apple apps.

See these KB documents for various warnings against the practice you're employing.

Good luck!

OK,

I'll know for the future.

I understand that it is a good thing to rename an application. We usually refer to an application using its name so this makes sense. The developer of the application can lock the name of the application so newbies are not going to be able to rename them.

But if I have many Macs for example, it seems to be a good idea to put some application on the server: one version for all, one version to maintain.

I am a Developer and my experience tells me that is not good to assume things.

My actual install uses symbolic links so usual paths are still working.

I believe the quality of the applications produced by Apple is decreasing. It is bad the say...

Thank you for the references.
