Packaging an "app bundle" for Mac requires a little work, and there isn't
any automated packager for Mono apps yet that I'm aware of.
You should create a directory called YourAppName.app, which is the "app
Create a file YourAppName.app/Contents/Info.plist. This is the app manifest,
and specifies various information about the application - its name, icon,
version, file associations, etc. It's quite well documented on Apple's site.
The icon referred to in the Info.plist should be an "icns" file which you
can compose from pngs using Apple's Icon Composer tool, and should be
located in YourAppName.app/Contents/Resources.
The Info.plist also specifies the executable that should be run when the app
bundle is run - this should be a shell script
in YourAppName.app/Contents/MacOS invokes Mono to run your exe. Your
program's "real" executable files and supporting files should be
in YourAppName.app/Contents/MacOS or some subdirectory of it.
For your shell script I suggest taking some code from MonoDevelop's script (
specifically the exports of DYLD_FALLBACK_LIBRARY_PATH and PATH, which will
ensure your app works even if MacPorts interferes with the Mono environment,
and the section "#mono version check", which will prompt your users to
install Mono if it is not installed, instead of just dying silently.
