# GStreamer SDK documentation : Installing on Mac OS X This page last changed on Jun 12, 2013 by xartigas. # Prerequisites To develop applications using the GStreamer SDK for OS X you will need OS X Snow Leopard (10.6) or later and [XCode 3.2.6](https://developer.apple.com/devcenter/mac/index.action) or later. The recommended system is [Mac OS X Lion](http://www.apple.com/macosx/) with [XCode 4](https://developer.apple.com/xcode/) Installing the SDK for 32-bits platforms requires approximately 145MB of free disk space for the runtime and 193MB for the development files. Installing the SDK for 64-bits platforms requires approximately 152MB of free disk space for the runtime and 223MB for the development files. # Download and install the SDK There are 3 sets of files in the SDK: - The runtime files are needed to run GStreamer applications. You probably want to distribute these files with your application (or the installer below). - The development files are **additional** files you need to create GStreamer applications. - Mac OS X packages that you can use with [PackageMaker](https://developer.apple.com/library/mac/#documentation/DeveloperTools/Conceptual/PackageMakerUserGuide/Introduction/Introduction.html) to deploy GStreamer with your application Get **both the runtime and the development installers** from here:

On Mac OS X 10.6 (Snow Leopard) you have to install Python 2.7 manually. It is included in later versions of OS X already. You can get it from here. |

Due to the size of these files, usage of a Download Manager is highly recommended. Take a look at this list if you do not have one installed. If, after downloading, the installer reports itself as corrupt, chances are that the connection ended before the file was complete. A Download Manager will typically re-start the process and fetch the missing parts. |
