There is an interesting bug with Aperture's export presets and the color profile used.

For context: Aperture Exporter utilizes an Aperture export preset whenever it is creating JPEGs or TIFFs with adjustments baked-in. By default, the preset it uses is the "TIFF - Original Size (8-bit)" profile. If one were to modify this profile from the defaults, AE will pick up on the modification and use it.

The problem is that certain color profiles cause Aperture to crash. Note this is not specific to AE's interaction with Aperture. Doing a manual export will also crash Aperture.

Problematic Color Profiles

The profiles that have been confirmed to crash Aperture include:

  • Adobe RGB Linear
  • Generic Linear

Other tested profiles did not exhibit any crashes. However, this list may not be comprehensive.

Solution

Ensure your Aperture export preset uses a compatible color profile such as sRGB or Adobe RGB (1998), and avoid using the linear variants listed above.
