Oct 02, 2015 Applecare support just told me today that in El Capitan Disk Utilityâs First Aid routine does in fact repair permissions on files that it can access. For a complete repair of all issues they recommended running Disk Utility from the Recovery partition, which should repair any mis-set permissions even on files protected by SIP, as well as. Jan 22, 2016 A light explanation of what Disk Utility does in older version of Mac OS X and what El Capitan now does automatically is available on this CNET page. More detail is explained on this Macworld page. It is important to understand that Repairing Disk Permissions has nothing at all to do with Spotlight or Spotlight indexing.
Disk Utility is a system utility for performing disk and disk volume-related tasks on the macOSoperating system by Apple Inc.
Functions[edit]
The functions currently supported by Disk Utility include:[1]
Disk Utility functions may also be accessed from the macOS command line with the
diskutil and hdiutil commands.[3]History[edit]
In the classic Mac OS, similar functionality to the verification features of Disk Utility could be found in the Disk First Aid application. Another application called Drive Setup was used for drive formatting and partitioning and the application Disk Copy was used for working with disk images.
Before Mac OS X Panther, the functionality of Disk Utility was spread across two applications: Disk Copy and Disk Utility. Disk Copy was used for creating and mounting disk image files whereas Disk Utility was used for formatting, partitioning, verifying and repairing file structures. The ability to 'zero' all data (multi-pass formatting) on a disk was not added until Mac OS X 10.2.3.[4] Further changes introduced in Mac OS X Tiger, specifically version 10.4.3, allowed Disk Utility to be used to verify the file structure of the current boot drive. Mac OS X Leopard added the ability to create, resize and delete disk partitions without erasing them, a feature known as live partitioning. In OS X El Capitan, Disk Utility has a different user interface and lost the ability to repair permissions due to obsolescence,[5] create and manage disks formatted as RAID, burn discs and multi-pass format internal solid-state drives and encrypted external drives.[6]

If youâre seeing strange problems with passwords on your Macâsuch as having to enter the same Wi-Fi network password every single time you try to connectâitâs possible that somethingâs wrong with your keychain. Keychains are a part of the Mac's system of storing passwords and other sensitive data and controlling access to that stuff. You know how your computer will ask you if you'd like to save a password into your keychain? That's so you don't have to keep typing it in. It'd be a bummer if Apple Mail made you enter in all of your email account passwords whenever you needed to send a message.
Anyway, the program that controls all of the keychains (and thus the stored passwords) that you have is called Keychain Access, so that's where we'll do our troubleshooting for the purposes of this tip.
One of the common symptoms of a potential keychain issue is this familiar but incredibly annoying alert from Mail, especially if you start seeing it all of the time:
Of course, that box can mean tons of things, from network or server troubles to your password actually being incorrect (surprise!), but it can also indicate that something's wrong with the keychain entry that's storing that password. To check it out, first open the aforementioned Keychain Access program, which lives in your Applications> Utilities folder.
Here's its pretty little icon.

Once itâs open, click on the 'Keychain Access' menu in the upper-left corner and choose Keychain First Aid.
In the window that appears, youâve only got two optionsâ'Verify' and 'Repair.' If you just wanna see if anythingâs wrong, click 'Verify,' type in your account password, and then choose Start. If youâd like to fix problems as they're found, select 'Repair' instead. Pretty self-explanatory, right?
Whew!
If the program finds and fixes anything, try doing whatever caused you to want to repair your keychain in the first place and see if the issueâs been resolved. If not (or if the First Aid tool didnât find anything, which is quite common), you can try some more serious steps, like searching for any keychain entries that are associated with the problem and removing them manually. So for example, if we pretend I've got a troublesome Gmail account that keeps prompting me for my password within Apple Mail, I can search Keychain Access for 'Gmail' and see what comes up:

That'sâ¦um, only about a twentieth of what's actually there. I have a lot of Gmail accounts.
I could then select some or all of those entries and press the Delete key to get rid of them, or I could double-click each one to see more details about what's stored there. If I delete an entry, Mail will request the missing password again (since Keychain Access no longer has it stored), and when I re-enter it, a new keychain item will be created. So if the problem is with one particular entry, that's an easy way to troubleshoot things.

Finally, if you're having tons of issues, a nuke-it-from-orbit solution would be to reset your entire keychain. Appleâs got a support article on that, but I really really really donât recommend you follow those instructions unless you know what youâre getting into and youâve got some serious problems with your keychain. If I didnât say âreallyâ enough there, let me do it some more. Be really really really careful with that, OK? Citrix receiver for mac 10.6.8.
