I am running OS X 10.11.8. I am attempting to change some settings in /Library/Filters/. I am logged in as an administrator (verified in System Preferences > Users & Groups). When I go to Finder > Get Info for /System/Library/, I am able to click the unlock icon, and my password is accepted.

However, when I try to change the permission for "everyone," I get the following error:

The operation can’t be completed because you don’t have the necessary permission.

How can I resolve this?

  • I've looked at this, but am not sure it applies. From the article "Paths and apps that third-party apps and installers can continue to write to include: ... /Library..." Thus, SIP shouldn't affect the library folder. – Adam_G Aug 8 '17 at 23:41
  • Your screenshot isn’t from Library - it is from the System folder. – Rene Larsen Aug 9 '17 at 0:29
  • Sorry, I didn't realize there was also a top-level /Library folder. I have updated my question. – Adam_G Aug 9 '17 at 0:55
  • Library/Filters/ & System/Library are no proper paths. It's unclear whether /System/Library/Filters/ or /Library/Filters/ is meant. – klanomath Aug 9 '17 at 1:35

You'll need to disable System Integrity Protection to make changes to permissions in /System.

To disable System Integrity Protection, you can do the following:

  1. Boot into the Recovery HD by restarting whilst holding ⌘R.
  2. Open Terminal (from the Utilities menu).
  3. Run the following command in Terminal:

    csrutil disable
  4. Restart.

Disable OS X El Capitan Rootless and permit write actions to System Integrity Protection locations

    @Pacerier How so? If one needs to make changes to /System, this is the standard way. It's not generally recommended to make changes to /System, yet this question wants to. The question may be an XY problem, but that is something to discuss regarding the question rather than this answer? – grg May 29 '18 at 15:17
