@section comp_mac_ca_1 Requirements
-* OS X 10.4 or later. PortAudio v19 currently only compiles and runs on OS X version 10.4 or later. Because of its heavy reliance on memory barriers, it's not clear how easy it would be to back-port PortAudio to OS X version 10.3. Leopard support requires the 2007 snapshot or later.
+* OS X 10.6 or later. PortAudio v19.7 currently only compiles and runs on OS X version 10.6 or later.
* Apple's Xcode and its related tools installed in the default location. There is no Xcode project for PortAudio.
-* Mac 10.4 SDK. Look for "/Developer/SDKs/MacOSX10.4u.sdk" folder on your system. It may be installed with XCode. If not then you can download it from Apple Developer Connection. http://connect.apple.com/
+* Mac 10.6 SDK. Look for "/Developer/SDKs/MacOSX10.6.sdk" folder on your system. It may be installed with XCode. If not then you can download it from Apple Developer Connection. http://connect.apple.com/

+By default, PortAudio is built as a universal binary. This includes 64-bit versions if you are compiling on 10.6, Snow Leopard. If you want a "thin", or single architecture library, you have two options:
* build a non-universal library using configure options.
* use lipo(1) on whatever part of the library you plan to use.
./configure --disable-mac-universal && make
@endcode
-The <i>--disable-mac-universal</i> option may also be used in conjunction with environment variables to give you more control over the universal binary build process. For example, to build a universal binary for the i386 and ppc architectures using the 10.4u sdk (which is the default on 10.4, but not 10.5), you might specify this configure command line:
