If you choose File > Import > iPhoto Library within Aperture, and you have iPhoto 6.0.1 or 6.0.2 installed, then Aperture won't import the iPhoto Library.
However, this feature does work with iPhoto 6.0, so a workaround is to remove iPhoto 6.0.1 or 6.0.2 and reinstall iPhoto 6.0 from the iLife '06 Install DVD. Here's how:
- From the folder /Library/Receipts, delete the files iPhoto.pkg and iPhotoContent.pkg.
- Move the iPhoto application from the Applications folder to the Trash.
- Run the iLife '06 Installer. When you get to the Installation Type screen, click the Customize button.
- In the resulting window, deselect every option except iPhoto.
- Click the Upgrade button.
- After iPhoto 6.0 is installed, launch it, and quit it.
- Import the iPhoto library into Aperture.
- Use Software Update to re-update to the latest version of iPhoto.
This issue will be resolved in Aperture 1.1.
This document will be updated as more information becomes available.
