+Compiling for 32 and 64-bit
+---------------------------
 
+All macOS versions after 10.6 are 64-bit exclusive, so the executable
+will be a ".64" file by default for most users. If you would like to 
+compile a ".fat" executable which contains both 32 and 64-bit code, 
+you can do so by specifiying the bits in the scons command like so:
+
+::
+
+    user@host:~/godot$ scons platform=osx bits=fat
+
