Repair/verify disk permissions and Preview problem.

The preview problem is yet to be solved + is outlined here:
http://discussions.apple.com/thread.jspa?threadID=298858&tstart=0
Also:
I decided to open up disk utility and verify disk permissions, this went fine. I then went on to 'verify disk' and it told me:
Volume Header needs minor repair
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
What's the solution? start up from OSX install disc? is this hard to do?

I am also having trouble with "verify disk permissions".
I have had frequent crashes recenlty and as a result upgraded to Tiger. The system crashes sometime when recovering from sleep (twice yesterday) and was crashing ferquently in Panther OS when hitting the odd key here and there.
Since upgrading to Tiger, I have apparrently successfully "repaired the disc permissions" on the start up volume, but then when I come to check them again, there are still the same problems, even though the "disk utility" has been run successfully. Have run disc warrior and "Verify disk" and still not convinced.
I also notice that the machine seems to be much slower running Tiger than before.
I avoided a complete install of the new OS because of all the aggro that involves, but it may be my only option if no one can help.
All thoughts appreciated.
Thanks

Slow. iMac 10.5.8. Verified Disk Permissions and then Repaired Disk Permissions. Not much improvement in speed. How do I empty internet files from safari?

iMac 10.5.8 is slow. Verified Disk Permissions and then repaired. No big improvement in speed.
What about internet files (safari and firefox) ; caches and cookies?
Thank you.

Applejack might help.

It runs in single user mode, where it runs more safely than other maintenance/cleaning programs because there is less chance of interference from the OS. After installing (you won't see it in the Applications Folder) hold CMD-S at startup. You will get a black screen with MS-DOS like text. Just follow the prompts: type in "applejack AUTO" and it will run through the following:
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
You can also run tasks selectively and for specific users by typing in "applejack." After running in "AUTO," you can go back and run it again as "applejack," steps 3 & 4 only, for your user.
The first reboot will take much longer than usual, as it rebuilds caches. It may take several restarts to see the benefits. Because of the deep cache cleaning in AUTO mode some applications may tell you they are being opened for the first time.

Disk Utility can't Verify Disk Permissions" and "Repair Disk Permissions"

I tried to run "Verify Disk Permissions" and "Repair Disk Permissions" on an external partition, but they all grayed out! "Verify Disk" and "Repair Disk" were fine! The "Owners Enabled" is "Yes". Why they were grayed out ?!
Get Info on this volume showed:
Ownership & Permissions:
You can "Read & Write"
Details:
Owner: admin
Access: "Read & Write"
Ignore ownership on this volume: checked or unchecked STILL grayed out!
Other partitions on the SAME drive are able to do "Very Disk Permissions" and
"Repair Disk Permissions" (as they are NOT grayed out !) The ONLY difference
between the one (CAN'T) and the rest partitions is that one (CAN'T) has
owner by "admin", and the rest partitions (OK to veryify pewrmissions) are owner
by "system". ANY CLUE ?
-DC

The options to verify or repair permissions are only available on a disk with Mac OS X 10.2 or newer installed, and all Mac OS X versions set the owner of the partition containing them to system when installed.

"verify disk permissions" and "Underlying task reported failure on exit"

This is more of a "How I fixed this problem, so others can benefit" posting than a current problem.
I put my MBP to sleep yesterday, and then when I tried to come out, it just sat there. After about 15 minutes, I figured I'd just force it quit and then restart.
After hitting the power button, it came up with the gray screen and apple logo with spinning gear and basically sat there for 20 minutes. Several reboot attempts were failures; sometimes I got a blue screen with spinning gears, but basically not much else.
I tried rebooting with the install disk, holding down the C key, but it gave me nothing, tried rebooting in verbose mode, tried doing CommandOption+PR, nothing, etc. So, I tried rebooting while holding down the option key, and I could see the Disk Utility.
I ran the Disk Utility to verify the disk, and that all came back fine. So, I ran Verify Disk Permissions, and i spit out "Underlying Task Reported Failure on Exit". The phone support people suggested I try reinstall with archive.
So, I tried running install with Archiving, and that failed as soon as it verified the DVD was ok - basically it couldn't access the HD.
So, I rooted around and did the following. From the Install disk, I selected "Terminal". Then, I did:
cd /Volumes
ls -lt
There I noticed that for some odd reason, Macintosh HD was listed as the following permissions:
rwxrwx---
So, admin and group had read-write-exec access to the Mac HD, but others had nothing, which I thought odd. It seems like you should at least be able to boot the computer to the login screen, and if a user is not admin or admin group, you cannot login, but I guess that's not the way it's set up.
So, I tried:
chmod o+r Macintosh HD
Then, I reran verify disk permissions. Again, I got the same "Underlying..." error. So I tried
chmod o+x Macintish HD
I then reran verify disk permissions, and it ran fine and the suggested that the Macintosh HD volume permissions should be set to:
rwxrwxr-t
So, I had the Disk Utility repair it to the way it should be, and now it all seems fine.
This suggestion basically did not come from any Apple Support people or any forums, and it seemed like such an easy fix that I'm surprised nobody (at least nobody I've found) has had the same problem or needed the same fix.
Further, I think figured out what happened. I took my computer to my local tech support guys because I wanted to turn off sharing for this MBP. So, under Macintosh HD, somebody changed the permissions under "Everyone" from "Read Only" to "No Access".
It turns out that doing this basically creates the whole problem above by making the Macintosh HD unmountable or inaccessible.
I find it truly odd that it would be so easy to remove access to the computer for mounting purposes, but this is the only thing I can think of. The tech guy realized his error and apologized and was also surprised it was so easy to hose the computer.
Anyway, this is partially a warning to everyone as well as a possible fix for the blue screen problem, especially since it was a solution I could not find anywhere.
Maybe Apple Support will see this and for its next update at least make a warning box when people try to remove "Read Only" access for "Everyone".
Good luck.

If your Mac still boots and runs most applications correctly, but applying Software Update packages fails and you decide to run Disk Utility to Verify Permissions and it fails almost immediately with the "underlying task reported failure on exit" explore this posting. If you see other errors, have slow/varied disk performance, or hear nasty grinding/clicking sounds you have a much more serious problem this solution isn't for you.
Use Applications, Utility, Console and check the messages appearing there each time you try Disk Utility. If you see:
Failed to open database on '/'. Error 14, 13, Permission denied.
You may have had your permissions reset on the receipts db. Which is found in
/Library/Receipts/db/a.receiptdb
At this point you have to enter the dark world of the Terminal and use a unix shell (command line).
If you are not comfortable doing find a Unix/Linux power user.
The simple fix for me was to open Applications, Utilities, Terminal and do
sudo chmod 755 /Library/Receipts/db/a.receiptdb
This allowed Disk Utility to read the file and move on to repairing permissions.
When things generate error messages in the GUI part of Mac OS X ...always go check the messages in the logs via the Console in Utilities. These messages are 'down a level' and get you much closer to the real problem.
Note that I did follow the instructions in Apple kb TS1901
http://support.apple.com/kb/TS1901
which did not help at all. Same problem each time:
xxxx-imac:Volumes user$ diskutil verifyPermissions /
Started verify/repair permissions on disk disk0s2 Macintosh HD

Now I wonder what changed the permissions on the receipts database file? I am off to use find and date fields to see what changed the permissions file last (my is dated sometime in November!).

Lion "Verify Disk Permissions" and "Repair Disk Permissions" grayed out

Please help!

Repair using Disk Utility was OK on the volumes, but Repair for the drive was grayed out.
That's very odd. Is your drive G.U.I.D?
Boot into Safe Mode (Hold Shift-Key), then boot normally.

Verify disk permissions: Error: The underlying task reported failure on exit.

I need help. My iMac has been doing weird stuff for awhile but now it's just out of control. I did a system restore from a time maching backup and I thought things were okay, but then I rebooted in safe mode just to see if it would help with the "slow" problem I had after the restore. Well, all I could get after that was a black screen. So I booted up from my install disk and ran verify disk permissions and got this error code: Error: The underlying task reported failure on exit.
I've also seen: Invalid node structure, etc.
I hope someone can give me some good advice. I've thought about purchasing Disk Warrior but am trying to put it off as I don't want to spend $100.
Thanks for any help.

Try this:
Repair the Hard Drive
Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro 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.

Verifying disk permissions

Just used the disk utility to verify disk permissions and got he following:
Group differs on “Library/Preferences/com.apple.alf.plist”; should be 80; group is 0.
After clicking repair it was all fixed.
Can anyone tell me what this actually means?
Thanks

just disregard it. It's not an issue.

Disk Permissions and Leopard

After installing Leopard Upgrade, I ran Verify Disk Permissions and got this:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
I did run Repair Disk Permissions but the above Warning remains. Everything appears to be running great. Is the above a concern and how do I deal with it?

I am getting the same message, I think it's a common occurrence.
I did the Leopard upgrade, I am wondering if people who did a clean install are getting the same message.

After clean install of Mountain Lion 10.8.5 no Gate Keeper and a ton a long list of differences in verify disk permissions after updating to Itunes 12.1

HI everybody.
I have a MacBopok Prop 15" from mid 2012, 2.6Ghz, Intel Core i7, 16GB RAM 1 TB SSD.
As my Mac was running as fast as possible it was getting slower down during start and shutdown, from 2 secopnds to 15 secconds during start and shutdown . Apps were crashing sometimes a freeze, total crash which made me go directly to Recovery HD and not my log in page after all the tricks I know I took it to service center where they zeroed my SSD HD and reinstalled Mountain Lion 10.8.5. Strangly enough Gate keeper was not in my preferences and a old version of Itunes 10.4 if I recall. The Mac is still slow while I reinstall all apps from App store and one for one documents and folders from my latest TM back up.
Updated the Security update, and other updates had the same problem as many updating Iphoto 9.4.3 error 102, still have not been able.
But running verify disk permissions there is a massive list of Itunes differences while I have not even added one song. At least 60 to 70 differences. I know a lot of these differences are nothing to worry about but a clean install without Gate keeper and an old Itunes which after update to 12.1 has so many disk differences, this can not as it should be also as I have not added anything from my Itunes library. Any feedback or advice would be very much appreciated.
Greetings
Matt

Do a backup. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then re-install the OS.

I've never run verify disk permissions before, but I finally have, and it says it's going to take an hour and 35 minutes to complete.

Although it keeps actively finding problems with the disk, the progress bar hasn't changed for more than a half an hour, and it still says it's going to take an hour and 35 minutes. I'm starting to worry it will never be done! My laptop, a Macbook Pro, is pretty old - about five years, and I don't know if the fact that I've never run a verify disk permissions before has anything to do with it.
The only non-greyed out option is to currently 'stop permission verify'.

Just let it run, it probably won't take that long. Also you may benefit from reading Disk Utility's Repair Disk Permissions messages that you can safely ignore.

Start Up Time, slowing down and Verify Disk Permissions?

Hey All, today since i was curious and i havent done it in a while, i timed my macbook start up time. It was clocked at 42 seconds, which is slower than what it used to be. Can you tell me your start up time? Also im a little inexperienced with Apple Computers i would like to know why its slowing down. Since it slowed down, i went to Verify Disk Permissions to see if maybe something was wrong and this showed up http://i19.photobucket.com/albums/b173/JoshSG/Picture1-2.png again, i repaired the permissions about a month ago and i guess it didnt clear up. Does that have anything to do with the start up time and any way to actually clear those permissions up?
Thanks
I hope it is not confusing

I am having the exact same problem- be curious to see if anyone has an answer. I think my problem may be related to time machine- if I unplug the firewire this doesn't seem to happen- not sure the 2 are connected. Do you use time machine via a firewire?

Verify Disk Permissions stalls and will not finish

I noticed a little slow-down in performance lately, so I tried to repair the disk permissions. I attempted to verify first, but the process gets to the very end of the status bar and stalls. This is the last text displayed in the window whe the stall occurs: "Permissions differ on ./usr/share/man/man1/less.1, should be -rw-r--r-- , they are -r--r--r--"
I stopped verification and went straight to repair, but that also stalled at some point.
Any ideas?
Thanks,

Interesting my post is still up there! But this is more recent:

Your device (ID=8723) is not covered by the FAQ, so I would be interested in what model scanner you have so that I can add it. However, I doubt this is causing your problem.
In the Console application you can have several windows open at once. You'll find the system log (and others) listed on the File menu (it will open a new window). You can aslo click on the "Logs" icon to see more. A good idea is to have both a Console.log window and a system.log window when you are trying something out, since some messages go to one, others to the second, and occasionally to both.
If you look at kmosx: Spurious Permissions errors in 10.2 you'll see your messages listed toward the end. As Rich said, if you see these you have very nearly finished. Incidentally, why are you bothering with "Verify Permissions"? There's no point doing that for most users, just go straight to "Repair Permissions".

Disk Utility can't "Verify Disk Permission" and "Repair Disk Permission"

I booted up the Leopard 10.5.5 server from the Install Disc, and tried to do disk checks on all drives using Disk Utility.
When the system drive was selected all the "Verify Disk", "Repair Disk", "Verify Disk Permission" and "Repair Disk Permission" functions are able to perform, however, if the non-system drives are selected only "Verify Disk" and "Repair Disk" are able to perform, the "Verify Disk Permission" and "Repair Disk Permission" are GRAYED OUT ! and UNABLE TO perform the permission check and repair!! Any idea ?

Hi, I'm having a problem could be related. I've a 3 years old Xserve (not intel) with 3 HD managed by the apple original RAID board, all that running Mac OS X 10.4.
I remotely manage the server from my mac running OS 10.5.6 and Server Admin 10.5.3.
Well, I simply cannot propagate permissions because when I do it, Server Admin freezes and i must force it to quit. Obviously, privileges are not propagated.
All that di NOT happen 1 month ago when i was "happily" running Mac OS X 10.3.x and Server Admin 10.3.x. Upgrading has been a big boomerang.
Any idea? Thanks

Disk Utility - Verify Disk Permissions / Repair

I run Disk Utility > Verify Disk Permissions with this rsult:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
The following repair was successful.
A few minutes later I run Verify Disk Permissions again with the SAME result:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
What does it mean and how can I stop this error?
Thanks!

There is nothing in that message that requires repairing. That is why it keeps showing up.
The permission database has to be updated every time the system is updated. If they miss a change that they have made in the system, it will get flagged as you see, but doesn't mean anything is wrong.
That KnowledgeBase article also must be updated to reflect the things they missed.
All that message is saying is that the directory derby is now replaced with a link to another directory (the l vs the d). However, mine doesn't have a link. Did you install anything that might have updated derby?
If you open Terminal and enter this code, can you post the line that has derby on it?ls -al /usr/share/
I'm repairing permissions now to see what pops up for me, but that will take a little while.
Edit: I looked into the Derby directory and Derby is a Relational Database Management System used by Apache. So, did you install something that modified Apache, PHP, mySQL or something like that? It might have altered the link.

My iMac, OS 10.7.5, is abnormally slow on start-up, taking many minutes for my password sign-in window to show up. I've run Disk Permissions and have verified my hard drive and all is in order. What do I do to start up my Mac in a normal manner?

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged after the boot, during the time something abnormal was happening. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. Please include the BOOT_TIME message at the beginning of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.
