Macos – Editing info.plist file

macos

I'm trying to change an option in the info.plist file, but every time I try to change it, an error box says that the file cannot be unlocked.

To try and change the permissions of the file, I went to the file's info, but I couldn't see my name on there.

When I tried to add myself as a user, it didn't let me add a new user, saying:
The operation cannot be completed because you don't have the necessary permission.

What can I do?

Best Answer

  1. Open Terminal & run the command below

    sudo chmod u+w /FILE-PATH

  2. Enter computer password when prompted.

Note : It doesn't show any characters while entering password

  1. Enter ls -l FILE-NAME+FULL-PATH in terminal to verify
