InstallBuilder for Mac

From BitRock:

BitRock Installbuilder provides you easy to use cross platform installers for Linux, Solaris, HP-UX, AIX, Windows and Mac OS X. BitRock installers are native binaries that can run on Windows ME, 2000, XP, 2003, Solaris, Mac OS X and on any Linux distribution. The generated installers provide native look and feel and desktop integration for Windows, KDE, Gnome and Aqua and are optimized in size and speed, reducing download, startup and installation time. BitRock Installers are single-file, self-contained native executables with no external dependencies and minimal overhead. All BitRock installers are truly native code, do not require bundling a Java Runtime Environment and provide an intuitive interface on all platforms, even for users without Linux experience. BitRock InstallBuilder includes an easy to learn, easy to use GUI environment that can be run on Windows and Linux. Create Windows, Solaris, FreeBSD, Linux (x86-PPC), AIX, HPUX and Mac OS X installers from a single build environment. For advanced users, a friendly XML project format supports source control integration, collaborative development and customizing projects both by hand and using external scripts. A command line interface allows you to automate and integrate the building process. QuickBuild functionality allows you to update installers in a few seconds, without having to repack the entire application. BitRock InstallBuilder provides convenient built-in actions for commonly required installation functionality such as changing file permissions, substituting text in file, adding environment variables, adding directories to the path, changing the Windows registry, launching external scripts and so on. BitRock installers can be customized in a variety of ways, graphically and in functionality, and run on GUI, text and unattended modes. An uninstall program is created as part of installation. BitRock Installers are platform and programming language independent.
