This question already has an answer here:
I want to modify DefaultFonts.plist for the Notes application. I've tried a few different ways since what worked on old OS doesn't on 10.14 Mojave:
- I've navigated to the file through finder, went to Get Info, unlocked the file (via the lock icon), and tried to change permissions.
I get the message "The operation can’t be completed because you don’t have the necessary permission."
I've tried this command:
chmod 777 /Applications/Notes.app/Contents/Resources/en.lproj/DefaultFonts.plist
I get the message: Operation note permitted
I've also tried:
sudo nano /Applications/Notes.app/Contents/Resources/en.lproj/DefaultFonts.plist
I'm able to get into the editor, but when I try to save I get message: "error writing /Applications/Notes.app/Contents/Resources/en.lproj/DefaultFonts.plist"
also, I cannot cd to /Applications/Notes.app/Contents/Resources/en.lproj. (And I cannot see Notes.app when I'm in the Applications folder.)
The application is closed while I'm doing all this.
I have admin permissions on my computer. What in the world am I doing wrong here?
UPDATE: I'm now able to edit the file thanks to @bmike. However, changing the font size values in the file doesn't seem to affect the application. I think I have the correct file. (btw, not sure if I should be writing this follow-up here or just in comments...or creating a new post. Feedback welcome.) Created new post to address this: Notes.app reverts back to default font when using bulleted list
