To repair or not repair, permissions that is?!?

I'm planning to update to SL and have been reading discussions about a recommendation to repair permissions before and after the update. Does this sound correct? and if so how do I do this?
Thank you for your time.

yes.

open Disk Utility, select your main hard drive and click "repair permissions". But MUCH more important is to make a full backup before upgrading. repairing permissions is extremely minor compared to having a backup.
Thank you for your time.

Disk Utility Repair Permissions conflict for ./Private and ./private

After applying the latest Security Update 2008-003 (PPC) (http://www.apple.com/support/downloads/securityupdate2008003ppc.html), Repair Permissions in Disk Utility has conflicting requirements for permissions on ./Private and ./private. One of them is wrong. This diagnostic needs to be fixed.

Unless you are using the case-sensitive file system, they are not different directories.
I have not yet installed this update, so I haven't seen this issue. I would say don't worry about it. In over six years of using OS X, I have never encountered anything in Repair Permissions that actually needed to be fixed. But I have seen plenty of nonsense like this, where it references the same file using different names, with different modes associated with the various names.

Repairing permissions, how?

hi, i just bought new macbook last week, and want to upgrade to 10.4.8, but am hesitant after reading some articles. what steps should i take to a proper installation (i know repairing permissions is one, but am not sure how to do so)?, or should i wait a little longer to install 10.4.8?

Hi Drew,
In OSX it is important to verify and (if necessary)repair permissions before and after you update the OS or install additional software.
You will be notified if OSX permissions differ and need to be repaired.
To do this you need to follow the following steps:
1 - Click on the FINDER icon in the dock
2 - Go to UTILITIES
3 - Open DISK UTILITY
when you open DISK UTILITY it will search for your HD and any other storage device connected to your Mac.
Select your HD it should be "Macintosh HD" unless you have changed the name.
On the right side of the DISK UTILITY window you will see a number of tabs
First Aid - Erase - Raid - Restore
of these select "First Aid"
At the bottom of the widow (just above the description of the selected hard drive you will see 2 buttons on the left "Verify Permissions" and "Repair Permissions" and 1 on the right side "Verify Disk"
Click on "Verify Permissions" to check the state of OSX if you see a message saying that permission differ then you need to "repair permissions"
That is it, easy and will save you some head aches in the future.
When using OSX you will find that sometimes (not very often) it starts acting strange or unusually sluggish, the first thing you need to do in these cases is check OSX permissions and if they are OK then use "Verify Disk"
I hope this helps

OS X System Freezes While Running Disk Utility repair permissions

While trying to pepair permissions systom freeze up. So I put in the startup disk hit restrat holding down c and tried to repair permissions that way and it froze up that way too. I had to manually turn off machine. What is going on?

Thanks for your response, I only have one disk. 10.5.1 I have 10.6 on usb drive. I will try running Disk Utility from the first DVD and instead of repair permissions try to repair your drives. The reason I was repairing permissions is I have an app called video converter and when I opened it I got an error window. Ok I will try repair disk. If that doesnt work I guess I will have to reinstall the os? Is that right? Ok, here I go to try it.

HT2963 When I repair permissions, get one reading that can't be repaired. "Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired." What does this mean?

When I repair permissions in disk untilities, I get one result that cannot be repaired:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
I recently had a new hard drive installed by Apple, after mine failed. The permissions seem to get out of whack quite often, and I get the message above.
Can you please tell me what may be going on?

Permissions Repair Not Repairing the Permissions that it Claims

I have a server that went down, and I successfully archived everything [necessary] on the System partition using "sudo cp -R". I copied this over to a different HDD, and used the migration assistant to restore data during installation. This effectively copied everything that I needed to recover from this server.
Understandibly, I had lots of permissions errors, and attempted to repair them using Disk Utility while booted in the OS. This fixed most permission errors, but when I verified again, it pulled up more errors. Repaired permissions again, and again but Disk Utility still claimed that the same files needed to be repaired. I booted to my install drive and tried repairing permissions through Disk Utility multiple times, but it still pulls up the same errors.
Most of these errors are that the 'd' flag is missing at the beginning of the file mode for files matching: /System/RemoteManagement/AppleVNCServer.bundle/Contents/LockScreen.app/Contents /Resources/*.lproj/MainMenu.nib
Other errors are .nib files in the ARDAgent.app, but there are fewer numbers of these.
I assume it's pretty bad if a file is supposed to be a directory but isn't, so what can I do about this? We use Remote Desktop quite a bit, so any deviation in the way it works can be pretty prohibitive.
Thanks in advance

The structure of some packages changed in an update. Unless you have an actual problem running Apple Remote Desktop, ignore those messages.
Running the repair permissions function repeatedly won't change or fix anything.

Mac won't update software or access iTunes shop. Message comes up with 'not connected to the net. Check connections' error. I still have internet access. Changed my Apple ID but no result. Repaired permissions and re-installed operating system.

It sounds like you may have multiple problems, but none of them are likely to be caused by malware.
First, the internet-related issues may be related to adware or a network compromise. I tend to lean more towards the latter, based on your description of the problem. See:
http://www.adwaremedic.com/kb/baddns.php
http://www.adwaremedic.com/kb/hackedrouter.php
If investigation shows that this is not a network-specific issue, then it's probably adware. See my Adware Removal Guide for help finding and removing it. Note that you mention AdBlock as if it should have prevented this, but it's important to understand that ad blockers do not protect you against adware in any way. Neither would any kind of anti-virus software, which often doesn't detect adware.
As for the other issues, it sounds like you've got some serious corruption. I would be inclined to say it sounds like a failing drive, except it sounds like you just got it replaced. How did you get all your files back after the new drive was installed?

DisK Utility Not Repairing Permissions

Hello, I have a problem with my iMac.
The problem is as following: I cannot repair permission using Disk Utility.
What happened first was that I wanted to install a program from a mounted drive, however a Pop up occurred and said the framework of installer was incorrect.
After that, I went to Disk Utility and clicked repair permissions when a Pop up like this came up:
http://img219.imageshack.us/img219/2582/picture1mt4.png
What is the problem?
Thank you for any help,
Daniel

-are you running Disk Utility from the HD or booted to the instal disk?
-what are the affected files?
If the file(s) was not installed by the mac OS X installer, Repair Permissions will not fix the issue
Tip:
If the files are located in your home folder,
boot to instal disk#1,
choose Reset Password Utility from the menu bar
and "Reset Home Directory Permissions and ACLs".

HD Not Accessible to Repair Permissions

Hello. I hope you can help me isolate the error that is keeping my Intel iMac G5 from booting properly. I’m running 10.4.
It froze after I’d been backing up onto DVD/dumping old data (about 20GB worth). Whenever I tried restarting the screen would freeze on the grey apple logo, sometimes with the swirly icon.
When I ran Disk Utility off the install disk at first it indicated “error detected” on mass storage, but later said it was fine. But I could not run Repair successfully (I kept getting "repair failed" messages), and the Repair Disk Permissions button was not accessible (greyed out).
I could not startup in safe mode. And if I tried to restart in DU the only option was a Network (which I'm not hooked up to).
Once I got a Kernal panic screen but most of the time it was just a grey apple with the fan hitting 900 rpm.
Finally I ran DiskWarrior and in 15 minutes it had cleaned out and rebuilt my HD. I thought I was home clear.
However, even though Disk Utility now says my HD is fine, it still does not allow me to Repair Disk Permissions - the option is greyed out. And if I boot up pressing Option to select a Startup Disk, the rebuilt drive is not one of them.
It appears my /Library/Receipts folder is empty.
What’s more, if I try to run an admin command in Terminal, like
sudo diskutil repairPermissions /
I get the message:
-bash: sudo: command not found
In fact, any way I try typing sudo I get a “command not found” message, even if I try to run other command like chmod.
When I type:
Users
I get
Users: command not found.
So I typed:
Echo $PATH
And get
/bin:/sbin:/usr/bn:/usr/sbin:/usr/libexec:/System/Library/CoreServices
I’m not sure at this point whether the fact that the DiskWarrior-rebuilt drive doesn’t show up among Startup options (when I boot with option key) is because of missing/broken permissions; an empty /Library/Receipts folder; missing users; or a missing path.
Any and all help is appreciated. Thank you.

Oy. I purchased an external drive and began installing Mac OSX onto it, so that I could then migrate all files from the unbootable hard drive before running an Archive & Install. That part seemed to go smoothly. But a few problems have emerged:
1. Though I was prompted to keep Disk 2 of the install ready, it never asked me for it, even though I ran the installation 2 or 3 times. Consequently while I can select the external drive when booting up command-S, I can only see Install window, Disk Utility or Terminal windows - never a desktop, preferences drop down, help menu, finder, all the things I'd typically see when launching my machine. Is this normal? Is there a way to force it to install only disk 2 if it has things it needs for full bootable GUI / access?
2. Booting up with the install disk, in disk utility I can see both drives but still cannot repair permissions on my affected HD. I tried via Terminal (repairPermissions, chmod or chown) commands; I keep getting error messages (command not found).
3. Switching cd / to my new drive in Terminal, I was able, I think, to change permissions (755) but when I open Disk Utility the drive is still not writable and "Repair Disk Permissions" is still grayed out.
4. I could not open Migration Assistant on the new drive via Disk Utility, so I copied it from the HD into its own folder on the new one, but am really confused about the whole Disk Image thing. If I create a new disk image and try to open it, convert or checksum it, it still is grayed out, I can never just open it. I tried running commands in Terminal to run that application on the external drive, pointing to the new folder, to the .app, to the contents, .dmg, and no commands seem to work, I keep getting the command not found message.
If I just run the A&I, I fear I'll lose my data which is why I wanted to migrate everything over before I did so. But if the user / owner permissions are screwed up and the only way to fix them is A&I, I don't know what else to do.
Is there ANY way to boot from the install, run Migration Assistant from the external drive (either through Disk Utility or Terminal) and copy all files from HD? If not, I guess I'll have to cross fingers and A&I.
Gee, I used to love my Mac ...

Please Help, After Kernel panic restart failed- apple swirl(6 hrs), SafeMode-failed, SUMode-sucess. Could not unmount disk to erase. Repair permissions-multiple fail errors:unable to set permissions on... unable to set owner and group...

Please Help, I deleted an account that was the same name as the administrator but was not the administrator. Also a samsung galaxy s phone was charging through the usb port.
I closed out a program and got a message that the temp file could not be stored/saved.
Then a Kernel panic message occurred and restart was necessary.

I am looking to solve without buying DiskWarrior unless only resort.

So it looks like solved it for now I will update later. What I did was after starting from the install cd for the 10.6 system I ran from terminal ran:
diskutil disablejournaling /dev/disk0s2
diskutil disableownership /dev/disk0s2
diskutil repairPermissions /dev/disk0s2
then i closed terminal and then when to disk utility and chose to repair disk with results all was fine. Then ran repair permissions and got similar results from terminal function next I erased disk and then chose to restore from time machine and it is now restoring! yea!

OS X 10.6.7 Canon All-in-One 480 Printer will not print files, only blank pages. Have to go to Utilities, Disk Utility and Repair permissions for a temporary fix. How can I get a permanent fix?

After upgrading to OS X 10.6.7., my Canon All-in One MP 480 printer will not print. it says it is printing, but the sheet of paper just runs through the printer and comes out blank. I finally went online to just answers.com and got a fix involving the System preferences, printer and fax. i was told to go to Applications in the HD, thenUtilities, then Disk Utilities, highlight the HD and check on Verify Disk. If it says Disk is OK, click on Repair Permissions. At first, that worked, but the next time I went to print after turning the printer off, it refused to print and just ran the sheet of paper through blank. Once that happens, there is no way to go back to printing the file that failed. I fiinally had to copy and paste the info from the file that would not print and put it in an email to myself and then print that. This is very frustrating, and I would really like a final solution for the problem.

There's a lot there, so I'll start with the parts I can answer quickly.
The "ACL found but not expected..." messages can be safely ignored, so says this article
http://docs.info.apple.com/article.html?artnum=306925
(look below all the "SUID" examples)
I had changed my Desktop image earlier but when the "Installing 1 item" window came up it changed back to the back ground that you first see on your desktop after installation.
Leopard installs updates a bit differently. If it's simply an application that does not change system files, it installs them like before, without having to restart. If the update is to the system, then you must immediately "restart," It then goes to that stars and purple screen to perform the installation. Before, it would do the installation while you still had control of the Mac and would prompt you to restart when it finished the installation. This change probably make things more secure and reliable, because you aren't allowed to do other things on the Mac while system updates are being installed.
Please post back with the remaining point of concern.

I've fixed the problem - I think.
I forgot I had the program "Little Snitch" installed on my computer. So I went into it and saw that it was blocking most of my connections for all the programs I use on a daily basis. Once I lifted the RULE to those certain programs - BAM - everything came back to life in an instant!

Disk permissions that cannot be repaired

I have two disk permissions that cannot be repaired and wanted to know if there was anything I can do about them. The are: Warning: SUID file "System/library/CoreServices/Finder.app/Contents/Resources/OwnerGroupTool"has been modified and will not be repaired.
Warning SUID file "usr/bin/lppasswd" had been modified and will not be repaired
I just uninstalled Skype and reinstalled it than ran repair disk permission when these showed up. I have run repair disk permissions several times afterward and they always show up now. Thanks for any help!

Installing OS X 5.5 combo upgrade will clear the problem. I had exactly the same warning downloaded the combo and install straight over the incremental 5.5 update and everything is now fine. Here is the link

Repair Permissions: Slow or Not Working?

Is the Repair Permissions function in Leopard NOT working, or just incredibly slow (and progress not showing properly)? Some would report that it IS working, but takes a long time, sometimes even a few hours. Any experiences?

"I'm having trouble with Parallels".
My new MBPC2D with OSX.5 worked fine, until I ran Parallel with Bootcamp partition. OSX.5 won't start anymore, since it is in an indefinite start up loop, before ever getting to a blue screen. Starting on XP works fine, as does an OSX.5 back-up on a FW disk.
So I did a complete re-install. As before everything worked fine until Parallels and Bootcamp. Same miserable result. What to do? Permissions repair does not complete while running the book hot.
I bought the new book for running OSX and XP at reasonable speed in the first place!

To repair or not repair, permissions that is?!?
