I'm adding some functionality to an existing QGIS plugin (EcoValuator from Key-Log Economics). After playing with the existing version of the plugin, it works on a PC, but not on a Mac. The issue is with a step in the code which calculates values in an attribute table.
Before diving too deeply into the code, is there a reason why the plugin would work on PC but not on Mac? What are some things I should look for?
I was unable to find mention of this on StackOverflow, QGIS documentation, or elsewhere.
