How can I change the default font size in Notes' DefaultFonts.plist on a Mac version 10.9

What I have tried:

  • Go to /Applications/Notes.app/Contents/Resources/en.lproj/
  • Add myself to read & write permissions.
  • But when I open DefaultFonts.plist it stays locked.

How can I put this in?

If you are editing the file with an application like TextEdit or Xcode, you also need write permission to the folder the file is in (or en.lproj).

You can also use another editor like nano:

sudo nano /Applications/Notes.app/Contents/Resources/en.lproj/DefaultFonts.plist
