Repair permissions - huge list

SInce updating from 10.7.4 to 10.7.5 on my macbook pro 2011 model I am getting a massive list when verifying permissions. After repairing they are still there?
Why is this happening and how do I fix it?

I ve never had this before with any previous operating system.
Mine arent in the "safely ignore" list either so what now?

Repair Permissions - Long list, but ultimately repaired?

This happened ever since I had upgraded to Snow Leopard a year ago on two different hard drives.
When I run Repair Disk Permissions, I get a huge long list, which ultimately results in the end note saying that Permssions repair complete.
Each time I run it, it is the same thing, a long list lasting 7-minutes followed by Permissions repair complete.
Is this normal?
Should there be no permissions to repair at all?

Yes, and you can ignore what you see. For the most part, repairing permissions is not needed unless you have a problem requiring such.

Repair Permissions: list remains very long

How serious could the following be:
After repeated reruns of Repair Permissions, a very long list remains on my Main Disk of only three classes of defects, to wit
AA—nine times of the type:
Permissions differ on "System/Library/CoreServices/Front Row.app/Contents/PlugIns/FRSources.frappliance/Contents/CodeResources", should be -rw-r--r-- , they are lrw-r--r-- .
BB—several hundreds of times of the type:

(as well as two of the type: ACL found but not expected on "Applications/Utilities").
CC—two times of the type:

Warning: SUID file "sbin/restore" has been modified and will not be repaired.
Observation:
all, with the exception of CC, are located in "System/Library/…",
and
"Disk Repair" is OK.

You're very welcome, Steven.
Just so you know, I used to run repair perms all the time.
I thought it was a maintenance procedure.
It's not, really. The only time to run it is if something's wrong (which is why you ran it)
or after installing major apps (but many folks that I respect here, say it isn't necessary even then.)
Five years ago, it was the "be all and end all" to maintaining a "healthy" Mac. Not so anymore.
So, do read a few of the threads from the link.
You'll find TONS of people wringing their hands over the RP notations.
"I ran it over and over, and the 'errors' are still there!"
I read a few of your most recent posts, and I realized that you've been trying to get things squared away. I hope you're all fixed now, but if not, don't ever hesitate to come back any time.

Repair Permissions lists errors but does not actually fix them?!

After running permissions repair, after taking longer than it should have, as I have found to be a common problem with all Leopard users, I received the following output:

I think this definitely is indicative of why I have been having trouble running my web host, as I always get the message 'cannot connect to localhost.' However, why did permissions repair not repair these permissions? It seems that it just essentially ran verify permissions instead.
I ran sudo diskutil repairpermissions /

Can Repairing Permissions Harm Regular Operation

I have read many times that repairing permissions cannot harm normal operation of your mac and .... it's certainly never caused me any problems as I run permissions repair every so often.
The reason I ask though is because of a buddy of mine whose mac, running OS 10.5, was running sluggishly. Out of curiosity I asked - "have you ever repaired your permissions" and he said - "what's that?" So I decided to run "Verify" permissions just to see what came up and it was a huge list. I told my friend that I did not know if this was a cause of his computer's sluggishness but that if he wanted I would run "Repair" permissions. He said to go ahead. So I did.
A few days later he was trying to update through "software update" iTunes and Safari ... and he tried to install "App Delete" as well. His mac would not install any of these apps. When he took his mac to the the Apple store they asked if he had recently repaired his permissions and he said "yes." they said that was the problem and that he shouldn't repair permissions unless he had a problem. (To me "sluggishness" is a problem.) Since he had all his stuff backed up the proceeded to wipe his computer and do a clean install. Seems a brute force fix to me. Personally I would have loved to sleuth a more subtle remedy, even if for nothing more than learning more, about the workings of OSX.
So, did I mess up my friends mac?
Any opinions?

There is no reason to repair permissions unless there is a permissions related problem. Repairing permissions is not a troubleshooting or maintenance procedure. Repairing permissions will not fix "sluggishness." That would be caused by any number of things, but not permissions.
You did not mess up your friend's Mac. It was already messed up, and it's still messed up for some other set of reasons.
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard. These utilities have limited or no functionality with Snow Leopard and should not be installed.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc. Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.
For emergency repairs install the freeware utility Applejack (not compatible with Snow Leopard.) If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard. AppleJack is not compatible with Snow Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. Tri-Backup (Commercial)

New Mac Mini and Repairing Permissions

I've been having trouble with my Mail program and thought I would repair permissions to see if that would help. I ran disk utility from my internal hard drive and ran repair permissions. Apparently it found several permissions to repair, so I thought I would run repair permissions again and the same list appeared. Running a third time and the same list appeared again.Do these permissions ever get repaired? What do I do from here? Should I repair permissions after booting up off of my original system disk? This Mini is only a couple of weeks old and I'm already having problems with Mail and repairing permissions.
rskover

Thank you Tim but the computer is packed back waiting for TNT to take it back to Apple. I don't have time to play with permissions, the permissions are OK in the old computer.
This is what may have been your problem. The permissions on your old computer may not have matched the new computer. I think you gave up before the penny dropped.
They sell the computers very expensive and I think they would have to improve quality.
I am unsure how that can be one of your gripes as when the cube came out it was way overpriced in comparison to their other desktops. That did not stop your or I getting one then.
Your issue was a software problem not a hardware problem so no matter what kind of mac you had it would have needed troubleshooting.
The quality of the new mac mini far exceeds that of the cube. Try playing 1080P high definition media on your cube, or even 480P for that matter. Try outputting 5.1 surround sound from your cube without the addition of a firewire audio interface.
I know how frustrating it can be when something just does not seem to work. I have encountered this a few times in my work. However sometimes I just have leave it come back with fresh eyes and try other approaches and I succeed.
What you need to appreciate installing an upgrade should be planned for any eventuality. In business upgrades are scheduled to have the minimum impact on the workplace. That being said I have worked 48 hrs solid over a weekend getting systems up for a monday morning. They are not always straightforward.

Repairing permissions - ERROR: NO VALID PACKAGES

I think I may have deleted something important!
I had a bit of a tidy up the other day, mainly deleting printers & fonts that I don't use. But it looks like I may have removed a few important things.
In disk utility, I can no longer repair disk permissions. When I try, I get a box saying;
FIRST AID FAILED
DISK UTILITY STOPPED REPAIRING PERMISSIONS ON "MACINTOSH HD" BECAUSE THE FOLLOWING ERROR WAS ENCOUNTERED:
NO VALID PACKAGES
Is there an easy way of fixing this? Or am I looking at a reinstall of Tiger?

Glad that sorted your immediate problem.
On the face of it I would have thought that none were necessary, as the name of the folder and the fact that they're installer packages for things that have already been installed would seem to indicate that they are not needed. BUT the fact that the loss of one of those files caused a problem with something that can be as important as the ability to repair permissions is pretty clear evidence that the files in there are used for something!
So, I would recommend leaving alone the packages for apps/etc. that are still on your machine, or files that you do not recognize. On the other hand, there are some items (very few, actually) in my receipts folder that I would feel comfortable deleting, e.g. a virus defs package for Norton, which I installed right when I got my MBP, but it utterly failed for reasons I won't go into here, and I actually ran the uninstaller to get rid of it, but clearly it left this little gift for me. And poof, it's gone.
But the majority I would recommend leaving alone. On my HDD the Receipts folder is ~170 MB, so it's not a huge chunk, but of course every little bit adds up!
Hope this helps...

Error message: There is a problem accessing one or more files in your iPhoto library. Do you want iPhoto to repair permissions for this library for you?

I have been using iPhoto for years. Today when I tried to upload pictures from camera, I received the above error message. I select "Repair", enter my password, and then a message "iPhoto was unable to repair permissions for the library" appears. I select "Quit" and it closes iPhoto. Quit is the only option. What has happened? I have tried to access the photos via other avenues such as uploading to gmail, and the photos load fine. I have about 28,000 photos.
I do not know what version of iPhoto I am using as I am unable to access the software. I have a iMac OS X (10.7.5). What should I do?

Select the iPhoto application in the Applications folder and type Command+i to bring up its Info Window. There will tell the version number. If it's iPhoto 9 or later apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #3, followed by #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Yesterday I ran Disk Utility and came up with hundreds of permissions that needed repair. I hit the "repair permissions" button and waited until it said they were repaired, but just for fun I hit the "verify permissions" button again, and they all came back! I did this several more times and every time I would hit "verify permissions" I would get the same list. What's up? I've always suspected diagnostic programs, but this is Apple's own!

Ignore them. They aren't errors. You will keep seeing the same ones. As long as you get the message "Permissions repair complete," you're OK.

Should I repair permissions before or after updating to Mac OS X 10.7.2?

Hi,
Should I repair permissions before or after updating to Mac OS X 10.7.2? or should I fix permissions before and after the update?

This is not a routine maintenance. Upgrades can be screwed up if the system that is upgraded is screwed up. I believe in a "better safe than sorry" approach. If you repair permissions and the hard drive prior to an upgrade then if there be a problem perhaps that problem will not propagate to the new upgraded system. If there are no problems doing the repairs is harmless.
When it comes to the topic of permissions repairs there are many opinions but not much fact. In other words there doesn't appear to be a formal analysis of whether repairing permissions is only useful when a permissions problem arises. But there is a lot of anecdotal evidence suggesting that a repair both before and after a major system upgrade can reduce the risk of problems.
This is my opinion on the matter. I do not generally disagree with Niel or MacJack, but as I said I prefer to be safe rather than sorry.
Here's my general approach:
How to Install Lion Successfully - You must have Snow Leopard 10.6.7 or 10.6.8 Installed
A. Repair the Hard Drive and Permissions:
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.3.) if DW cannot fix the drive, then you will need to reformat the drive and reinstall Snow Leopard.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the backup volume. Source means the internal startup volume.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade to Lion:
Purchase the Lion Installer from the Mac App Store. The download will start quickly. Lion is nearly 4 GBs so a fast internet connection is essential. Download time could run upwards of 4 hours depending upon network conditions and server demands at the time.
Boot From The Lion Installer which is located in your Applications folder.
Follow instructions for installation.

Repairing permissions gives me tons of errors

I've been having trouble opening some apps (i.e Activity Monitor) so I figured I should repair my permissions. When I do so, I get a HUGE amount of errors, I'll include just a very small portion of them below.
Any idea how to fix it?
Thanks!

There is also this article on resolving permissions issues:

As for your question about reinstalling without losing preferences, yes, it is called an Archive and Install:
http://docs.info.apple.com/article.html?artnum=301270
None, if you upgraded Mac OS X since you initially got the machine, it is more difficult to archive and install, as newer applications may not work right with the older operating system.
I would still though backup your data before doing it as my FAQ explains:
http://www.macmaps.com/backup.html
Even a corrupted backup is better than none, as critical data files can be rescued if there is an issue.

Repair permissions

I dont know whats the problem but almost every week I have to repair permissions with Onyx. The list of repaired permissions is only refered to the print system .DSstore and they are a few lines but obviously something goes wrong and I need some advice.

Repairing permissions is over-rated. (1) It is rarely necessary. It is not a maintenance thing. It is used when something specific is not working correctly because of a permissions problem. Third party system maintainers love to do useless stuff like this for you to give them more *apparent* substance. (2) There are almost always some permissions that show up as needing repair or cannot be repaired but which are safely ignored. Unfortunately third party system maintainers (which are mostly unnecessary) flag these things as problems. Probably (2) is what is happening to you.
See, for example,

Can't repair permissions in iPhoto 9.6

Upgraded to iPhoto 9.6. On opening get message: "The photo library needs to be upgraded to work with this version of iPhoto." When I click UPGRADE, I am "invited" to repair permissions of this library. When I select REPAIR, I am informed that "iPhoto was unable to repair permissions for the library." When I use command-option open iPhoto is First Aid mode, I have tried "Repair Permissions", "Repair Database", and "Rebuild Database" --- they all generate the same message, that "The photo library needs to be upgraded to work with this version of iPhoto". When I click UPGRADE, I loop back to the same earlier alert that the permissions need to be repaired. Can't repair the permissions. Can't repair or rebuild the database. Suggestions? PLEASE?

What version of iPhoto did you have prior to upgrading to 9.6? If it was iPhoto 7 (08) or earlier you'll need to download and run the iPhoto Library Upgrader 1.1 on the library and then open it with iPhoto 9.6. Otherwise try the following;
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.>Click on the Add Library button,

4 - now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option
5 - in the next window name the new library and select the location you want it to be placed. Click on the Create button.
Note 1: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost.

Warning message when repairing permissions

I Just repaired permissions and the usual large list showed up. But this time I got a message that says:
"Warning: SUID file "System/Library/CoreService...ent" has been modified and will not be repaired.
I navigated to that site and could not find a SUID file. Does anyone know what that stands for and could this be a problem?
Thanks for any assistance.
Rich

Thanks Macjack,
I seemed to get that response after updating to 10.6.7 and my confusion is that when I go to Core Service Folder in the Library, I don't even see any SUID File at all? And this is the first time I have ever received a warning that a file has been modified and not repaired. Have you seen a warning like this before?
Rich

Does repair permissions etc. need to be done after upgrade to 10.6?

My used Early 2009 Mini came with Leopard and I upgraded it to Snow Leopard. Haven't had the chance to use it yet. Need to update to the latest version of SL. Just wondered if I should do repair permissions etc. before using it. Or install all of the software I need and do the repair permissions etc. after that.
Thanks.

How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current Tiger Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger and later.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).
