The MGTHEME file extension is associated with MacGourmet Deluxe, a recipe and cookbook management application from Mariner Software for Mac OS X and macOS.
An .mgtheme file contains saved appearance or theme settings for the application. It allows a MacGourmet theme to be applied without recreating the settings manually.
This is an application-specific settings file rather than a recipe database or a general-purpose theme format. It is intended for use within MacGourmet Deluxe on Apple macOS.
Open an .mgtheme file with MacGourmet Deluxe on Apple macOS. Theme files are normally imported or selected from within the application rather than edited directly.
If macOS does not open the file with MacGourmet Deluxe automatically, launch the application and use its theme-related controls to load the file.
An .mgtheme file is an application-specific theme settings file, so it cannot be meaningfully converted to a standard format.
To use the settings, load the file in MacGourmet Deluxe. If a different appearance is required, select or save a theme using the application's own theme controls.
