Hey Gregg, Thanks for the logfile! Sorry about missing it there in your input archive as well.
So, the issue here has to do with path construction: On mac, forward slashes ("/") are used to indicate nested directories, and backslashes ("\" or “\\” in python) are used on Windows. Your info table uses backslashes to indicate paths to habitat/stressor vectors and the model isn’t correcting the paths to use forward slashes before checking to see if the file exists.
The short-term solution here is to update your info CSV to use the directory separator of your OS (forward slash on mac). In the longer-term, though, we’ll update HRA to correctly handle these path separator discrepancies and release the fix with an upcoming version of InVEST.
