I want to edit Finder Info.plist file that is located here:
But when I try to edit the file by
vi the file is readonly.
# vi /System/Library/CoreServices/Finder.app/Contents/Info.plist
When I try to
chown the file nothing happens.
When I try to change file permission from Finder I get the error: "The operation can’t be completed because you don’t have the necessary permission."
The Locked checkbox in Get Info is disabled.
I also tried:
sudo chflags nouchg Info.plist
But after all that, file is still readonly.
What is preventing
root from editing this file on OS X El Capitan 10.11.2?
