Download Catapult

The free trial is fully functional for 30 days with complete interactive and batch processing modes.

You can use a license key for Catapult or Catapult Lite (which does not have batch processing functionality) without needing to download & install again.

Download Trial for Aperture 3*

Once downloaded, you’ll get a disk image containing an installer application.
Run the installer application to install Catapult.

Once installed, the next time you launch Aperture, Catapult will be available in
Aperture 2.1’s Images > Edit With > Catapult menu,
or Aperture 3’s Photos > Edit with Plug-in > Catapult menu
when you select an image.

Also, please check the help documentation for notes regarding Aperture 3. You can access the help documentation by clicking the ? icon in the lower left corner of the Catapult window.

*It still works fine with Aperture 2.1, Mac OS X 10.5, and PowerPC. But we recommend Aperture 3.
