     \title Deploying an Application on Mac OS X
 
-    Starting with version 4.5, Qt now includes a \l {macdeploy}{deployment tool}
-    that automates the prodecures described in this document.

-    This documentation will describe how to create a bundle, and how
-    to make sure that the application will find the resources it needs
-    at run-time. We will demonstrate the procedures in terms of
-    deploying the \l {tools/plugandpaint}{Plug & Paint} application
-    that is provided in Qt's examples directory.

     \section2 Mac OS X Version Dependencies
 
-    Qt 4.2 has been designed to be built and deployed on Mac OS X 10.3
-    up until the current version as of this writing, Mac OS X 10.4 and
-    all their minor releases. Qt achieves this by using "weak
-    linking." This means that Qt tests if a function added in newer
-    versions of Mac OS X is available on the computer it is running on
-    before it uses it. This results in getting access to newer
-    features when running on newer versions of OS X while still
-    remaining compatible on older versions.
+    From Qt 4.6, Mac OS X 10.3 (Panther) is no longer supported.  Qt
+    4.6 applications can be built and deployed on Mac OS X 10.4
+    (Tiger) and higher. This is achieved using \e{weak linking}. In
+    \e{weak linking}, Qt tests whether a function added in a newer
+    version of Mac OS X is available on the computer it is running
+    on. This allows Qt to use newer features, when it runs on a newer
+    version of OS X, while remaining compatible on the older versions.

-    If you want to deploy to versions of Mac OS X earlier than 10.3.9,
-    you must build with GCC 3.3 which is the default on Mac OS X
-    10.3. GCC 3.3 is also available on the Mac OS X 10.4 "Xcode Tools"
-    CD and as a download for earlier versions of Mac OS X from Apple
