OS X 10.12.6, Sierra

My Sharing & Permissions says "You have custom access" and it's showing two entries for "everyone" where the first is set to "Custom".

  • This only seems to be affecting every single one of Apple's applications in the Applications and Utilities folders. I have no idea what other files are affected but a random search only turned up all Apple applications. All third-party applications are unaffected.

  • I did permissions repair using Onyx but it had absolutely no affect on these applications.

  • I cannot manually change permissions as the minus sign is grayed out after unlocking (see picture). Even if I could, it would take a very long time to manually find/repair.

  • I do not know what triggered this problem as I just discovered it today. However, I recently cloned my hard drive over to a new solid state drive using Carbon Copy Cloner.

  • I've already followed this official Apple procedure for fixing my Home folder permissions and I don't seem to have any problems there.

  • Everything appears to be operating, however, I'm seeing some strange problems like my ICC color profile will not stick after a reboot (permissions seem fine in the Library), but the ColorSync Utility instantly crashes when I click the "Repair" or "Verify" button.

I've already found and followed this thread, but the answer did not help.

This is a normal behavior of the Sharing & Permissions Info window in macOS systems protected by SIP.

The three latter are the POSIX permissions:

rwxr-xr-x@  3 root      wheel  restricted   102 Jul 22  2017 Activity Monitor.app
    com.apple.rootless

rwx read/write(/traverse(execute)) for the user root/system
   r-x read(/traverse(execute)) for the group wheel
      r-x read(/traverse(execute)) for everyone

The first entry (everyone > Custom) is a result of the restricted flag/com.apple.rootless attribute and can be interpreted as an ACL: group:everyone deny delete and the ACL can't be modified!

    I had SIP disabled for a while when I posted this, and just re-enabled it now. So you're saying that it's normal to see those "custom" permissions in Sierra for Apple's applications? Okay then, thank you. – Sparky Mar 19 '18 at 19:37

    @Sparky Yeah, it's completely normal - and the problem you have with ColorSync Utility is not related to its sharing & permissions settings! – klanomath Mar 19 '18 at 20:01

    @Sparky Is this a custom ICC profile? Probably better ask a completely new question! – klanomath Mar 19 '18 at 20:39

    No. Open ColorSync Utility. The "Verify" and "Repair" buttons have nothing to do with any specific profile. The app instantly crashes when the button is clicked. Yes, I understand about asking a new question. – Sparky Mar 19 '18 at 20:43

    @Sparky 1. First I would remove any custom profile from the various folders 2. Then try to verify/repair the profiles again (I found/verified 23 profiles in my VM environment) 3. add custom ICC profiles one by one (4. remove ~/Library/Preferences/com.apple.ColorSyncUtility.plist) – klanomath Mar 19 '18 at 21:58
