 === Upgrading applications for Macs with Intel processors ===
 
-Apple began shipping Macs with Intel processors on January 10, and Apple expects to convert all its lines of computers to Intel by the end of 2006.
-
-All future releases of BOINC will include 'universal binary' builds for the Macintosh of BOINC Manager, command-line BOINC client and the [BoincCmd boinc_cmd] command-line tool. (Universal binaries contain both PowerPC and Intel executables in one file; the Macintosh OS automatically selects the appropriate one for that computer.)
+Apple converted all its lines of computers to Intel processors during 2006.  The early Intel Macs used the Core Duo processor, which is a 32-bit CPU.  Later Intel processors, including the Core 2 Duo, can run both 32-bit and 64-bit applications.  However, BOINC will run in 64-bit mode only under OS 10.5 and later.
+
+All current releases of BOINC include "universal binary" builds for the Macintosh of BOINC Manager, command-line BOINC client and the boinc_cmd command-line tool.  (Universal binaries contain both PowerPC and Intel executables in one file; the Macintosh OS automatically selects the appropriate one for that computer.)  Beginning with version 6.1, the BOINC Client and libraries also include the 64-bit Intel architecture as part of the universal binaries.
 
 The advantage of 'universal binaries' is that you only need to have one copy of the application, and it will run on either PowerPC or Intel Macs, so users don't need to choose between two options. Since BOINC participants manually download BOINC from the web site, we will be providing BOINC in 'universal binary' form.

 However, participants do not manually download project applications; this is done automatically by BOINC. So there would be no advantage to combining the Intel and PowerPC versions in a single 'universal binary' file, but doing so would double the size of the download.
 
-So BOINC treats Intel Macs as a new, separate platform. BOINC previously directly supported four platforms: PowerPC Macs (`powerpc-apple-darwin`), Intel Linux (`i686-pc-linux-gnu`), Windows (`windows_intelx86`) and Solaris (`sparc-sun-solaris2.7`).
-
-'''We have now added a fifth platform for Intel Macs (i686-apple-darwin).'''
-
-As a '''temporary''' measure, projects can set their servers to deliver a copy of their current PowerPC application (renamed for the new platform) under the new `i686-apple-darwin` platform. The OS will run it in compatibility mode, emulating a PowerPC. (Apple calls this compatibility mode "Rosetta", which of course has nothing to do with the Rosetta BOINC project.)
+Starting with BOINC 5.9.7, the Intel BOINC Client accepts powerpc-apple-darwin applications if no i686-apple-darwin is available.   The OS will run it in compatibility mode, emulating a PowerPC.  (Apple calls this compatibility mode Rosetta, which of course has nothing to do with the Rosetta BOINC project.)  
+
+The x86_64 BOINC Client requests x86_64-apple-darwin applications from BOINC servers as its first choice, i686-apple-darwin as a second choice, and finally powerpc-apple-darwin if no Intel applications are available.
+
+However, older Intel Mac clients will not get any work unless the server offers i686-apple-darwin applications. 
+
+As a '''temporary''' measure, projects can set their servers to deliver a copy of their current PowerPC application (renamed for the new platform) under the i686-apple-darwin platform for older BOINC Clients. 
 
 If you do this, be sure to give your native Intel application a higher version number when you do release it, so that clients will download it.

 But Apple provides the tools to allow you to cross-compile your application on any Mac (PowerPC or Intel) running OS 10.4 or later. Here is how:
 
-All BOINC software for Power PC Macs must be built using GCC 3.3 and MacOS 10.3.9 SDK to assure backward compatibility with OS 10.3. If building a PowerPC application on an Intel Mac, you must also specify '-arch ppc' in the compiler and linker flags.
-
-All BOINC software for Intel Macs must be built using GCC 4.0 and MacOS 10.4.u SDK to allow cross-compiling. If building an Intel application on a PowerPC Mac, you must also specify '-arch i386' in the compiler and linker flags.
-
-You can find examples of how to do this for two different kinds of configure / make scripts in the HEAD branch of the BOINC SVN tree at [source:trunk/boinc/mac_build/buildcurl.sh boinc/mac_build/buildcurl.sh] and [source:trunk/boinc/mac_build/buildjpeg.sh boinc/mac_build/buildjpeg.sh].
-
-The lipo utility is used at the end of each of these scripts to combine the two binaries into a single 'Universal Binary' file. You won't need to do that with you project applications, since you will be distributing them separately under the two platforms. But if you prefer, you can create a Universal Binary and distribute the same file for both `i686-apple-darwin` and `powerpc-apple-darwin` platforms.

 Note that the BOINC libraries (and any third-party libraries) which you link with your applications must be built with the same configuration as the application itself. Follow the instructions earlier in this document to build the needed libraries.

+=== Upgrading applications for version 6 graphics ===
+
+One of the major changes in BOINC for version 6 is that applications are now expected to generate graphics in a separate executable. The graphics application typically communicates with the worker application using shared memory.
