"Preferences" has been renamed to "Settings" throughout the system in macOS 13¹. If we build against macOS 13 SDK, the in-app menu will display "Settings":

Although we can decide display settings or preferences depending on the system version programmatically, I prefer to just rename to settings regardless the system version.

Another decision to be make is that should we also change the "Preferences" appears in filename/variable names to prevent further confusion (e.g. PrefGeneralViewController)? I'm open to this.
