I would like to add that I am experiencing the same issue. We cannot package files using MacOS HighSierra and InDesign CC 13.0.1 If I downgrade InDesign to version 13.0 (NOT 13.0.1) it works again. This has been an issue for a while now and I would love to see it fixed.Patty Roberts supported this idea ·
