Description Attila Tamás Zimler 2012-07-17 06:54:28 UTC
The operating system's platform id is returned as Unix, however an enumeration value of MacOSX exists in the PlatformID enumeration.

With version of Mono Runtime:
	Mono 2.10.9 (tarball Mon May  7 20:25:51 EDT 2012)
	GTK 2.24.10
	GTK# (
	Package version: 210090011

On MacOSX Lion the following code snippet gives "Not MacOSX":

if (Environment.OSVersion.Platform == PlatformID.MacOSX)
	Console.WriteLine("Not MacOSX");
