How to modify "Archive Utility" Info.plist ?
Hello,
is-it possible to modify "/System/Library/CoreServices/Applications/Archive Utility.app/Contents/Info.plist" ?
I have this message :
The file "Info.plist" could not be unlocked.
Could not add write permission to the file because you do not own it. Try modifying the permissions of the file in the Finder or Terminal.
but it's impossible to modify permissions in the Finder ?
Thanks
