Lightbox XMP is an export plugin for Apple's Aperture tool that allows you to export XMP information, beyond what Aperture provides automatically, with your images. It is donationware, meaning that it's free, but if you like it, please make a donation to us to encourage more software development.

To install:

  1. Download the DMG from here, and it'll mount automatically
  2. Double-click the Install Plug-In tool (this makes the ~/Library/Application Support/Aperture/Plug-Ins/Export directory, where "~" means your home folder, and copies the plugin over there; should the installer fail, make this directory yourself and drag and drop LightboxXMP into it)
  3. Re-launch Aperture

Please make a donation if you find Lightbox XMP useful!
