Q: ACL found  but not expected.  Is this serial issue?

ACL = Access Control List. ACL's are  used to determine permissions for users. You needn't worry about the "ACL found but not expected" messages.

I got the same "ACL found but not expected.." messages, but at the end of the Repair Permissions, it says "Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired."

Should I be worried?

Is there anything I can do to not have the "ACL found..." not show up?

Thanks

Mac OS X: Disk Utility's Repair Disk Permissions messages that you can safely ignore

.

I received over 11'000 of these following an upgrade from one mac to another via Time Machine (largely around iTunes, iLife, and ARD Agent).  Called Applecare, was told they are not important (echoes the above).  Via help deleted caches and start-up apps and other items which caused other issues but these came back.  Their next alternative was to resinstall everything which, with nearly 500GB worth of files, is 5+ hour exercise with probably the same result.

Reluctantly I tried out the utility ACLr8  (http://nomulous.com/goodies/ACLr8/).  It solved the problem.  I don't know how or what it did (opens a terminal window and does its magic which I suspect is a macro that deletes each ACL error line by line - see other posts on how to do this).

I take no responsibility or liability but it appears to have worked.  Some have indicated it caused problems with Adobe software.  Since I only have acrobat reader, there was no risk (and I have a back-up anyhow).

the app still works with OSX 10.9.2

If I have 100 of them should I still not be worried? Seems kind of silly you can't fix it and you say it is not a problem then why does it even mention it in Disk Utility? I am running 10.10, I verify disk... do repair and then if i verify again I have the same issue. Which is funny because it actually says Repaired each acl...

So far the only thing I think it is effecting is when I put something in the trash it is immediately deleted... which I don't like.

This phenomenon appeared on my installation of Mavericks on a Mac Pro Tower 3,1 yesterday. I have been running Mavericks on that machine since last year. I find it shocking because it has never come up in the many Disk Utility repairs I have run on this machine with this OS.

Although the report said D.U. had repaired each instance of 'ACL found but not expected', subsequent disk repairs showed the same errors.

As suggested elsewhere in this forums, I downloaded, installed, and ran ACLr8. Following that I ran D.U. permissions repair again and the ACL messages did not appear.

I am probably not alone in my curiosity regarding the cause of these errors. Why do they appear? Is there a triggering event? As a fairly involved user interested in what's under the hood I would like to know. Any Apple folks who can speak to this please, do!

Same thing for me.  We have a new 27" iMac Retina Display with a 3.12 TB Fusion Drive, 32GB Ram and an AMD Radeon R9 M295X with 4GB of GDDR5 RAM.  We use our iMacs every day for hours for a lot of demanding Performance Simulation and Building Information Modeling work.

I noticed a huge number of "ACL found but not expected messages" so I ran ACLr8 which worked fairly fast.  But then I re-ran Disk Utility to verify the permissions and lo and behold hundreds of "ACL found but not expected" instances came back - fewer than before I ran ACLr8 but hundreds more than when  I first fired up this new iMac a few weeks ago.

I worry - albeit it slightly - that these persistent ACL files may slow down the processing of the iMac and make disk-seeking slower as the disk-seek algorithms parse through thousands of permissions files before bringing up the desired file.  Our need for speed and reliability is critical which is why we opted for the all OS X hardware/software infrastructure we use for many hours every day.

If anyone from Apple reading this has some suggestions for cleaning out these files??  Please??

Just to make sure I ran ACLr8 again and then ran Dik Utility.

All the "ACL found but not expected" instances are back even after conducting a permissions repair....

Can anyone at Apple comment on this?

Would really like to hear ay replies from Apple on this. I am getting this all the time now. Is this why my MacBook Pro is SO slow?  Disk Utility reports that the permissions are fixed, and then they all show up again on the next scan by Disk Permissions.

Yes it sure helped me! Downloaded the file, had to give it permission to run by clicking "Open Anyway" in the Security & Privacy Preferences.

It took some minutes to run, ant told me it cleaned all of them. Checked it with Disk Utility and there where none left.

Thanks for the help :-)

I had a 190 pages of ACL not found. I applied your link, then re-did DU, and the same issue. Can you imagine? If Permission Repair is supposed to "repair" why doesn't it work? I guess not even Apple knows how to fix the problem. At least I am not getting Panic Attack screens and what not.
