+There are two wxWidgets ports to Mac OS. One of them, wxMac, exists in two versions: Classic and
 Carbon. The Classic version is the only one to work on Mac OS version 8. The
 Carbon version may be built either as CFM or Mach-O (binary format, like ELF)
 and the former may run under OS 9 while the latter only runs under OS X.
 Finally, there is a new Cocoa port which can only be used under OS X. To
 summarize:
+
 \begin{itemize}
-    \item If you want to test for all Mac platforms, classic and OS X, you
-        should test both \texttt{\_\_WXMAC\_\_} and \texttt{\_\_WXCOCOA\_\_}
-    \item If you want to test for any GUI Mac port under OS X, use
-        \texttt{\_\_WXOSX\_\_}
-    \item If you want to test for any port under Mac OS X, including, for
-        example, wxGTK and also wxBase, use \texttt{\_\_DARWIN\_\_} (see below)

+The convention is to use the \texttt{\_\_WX} prefix for these
