macOS Location of main nib file for applications?

[dmmcintyre3]

I cannot find the main nib file for any applications. I can find everything but say in system preferences the window that opens when you start system preferences.

Right click on the application, click "Show Package Contents", --> Contents, --> Resources --> English.lproj

I did that and the main window was not there.

I did that and the main window was not there.

The nib is often called "MainMenu.nib" and has the menu bar and app object and the primary window (if there is one).

There is no requirement for the "main window" to be in a nib at all: it could very easily be created programatically at run time.

Find all the NIB files in an app(in this case, System preferences):

Open up terminal and type:

find /Applications/System\ Preferences.app/Contents/Resources/English.lproj/*.nib
