AppStartSaver

AppStartSaver is a reliable and straightforward screen saver designed for Mac OS X users. It is specifically designed to launch a pre-selected regular Mac application or Unix executable of your choice when the screen saver starts. The application can launch both Mac OS X (native, classic, or mixed) applications and Unix command-line scripts seamlessly.

With AppStartSaver, compiling AppleScripts as Carbon applications using the Script Editor becomes possible. The application also allows you to specify documents that should be opened when you launch the application. For Unix commands, you can specify command-line options passed to the command.

Controlling the opacity or transparency of the black window that the screen saver uses to black out the screen is intuitive. If you choose to set it as transparent, you'll see the regular Mac desktop and windows while the screen saver runs. This enables you to use the launched application's output as a kind of screen saver or to monitor its progress.

In conclusion, AppStartSaver is a versatile screen saver that ensures you remain productive even when the screen saver is running. It is a must-have application for Mac OS X users that simplifies launching applications or Unix executables with every screen saver start.
