Paul, I was wondering if anyone else reported the following error when trying to run a stochastic model on the Mac OS X (1-30-15) version of SAM. Please see attached image. I tried to setup the same model that you reviewed on the webinar to see if it was an input/output issue, but I get the same error message. Can you confirm this is a Mac issue and not a user or input-related error. Thanks in advance, Brian
