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?

You'll need to disable System Integrity Protection to make changes to permissions in /System.
Disable OS X El Capitan Rootless and permit write actions to System Integrity Protection locations
