There is an active project that specifically supports the Mac OS X platform at http://www.macada.org.
The MacAda site currently focuses on providing the compiler as well as integrating the compiler into the standard Mac OS X Xcode Integrated Development Environment. Here, we provide limited support and resources for GNAT/GPL.
The MacAda project appears to have a goal of providing pre-built libraries for some of the same libraries that we provide here however as of this writing, the list is shorter than what we provide for most platforms we support. While we would welcome a maintainer for the GNUAda project to provide and bundle libraries for Mac OS X from this project, interested parties should first consider working with the MacAda project to avoid diluting efforts on this platform.
