From the developer:
XTide is an application that provides tide and current predictions in a wide variety of formats. Graphs, text listings, and calendars can be generated. The program is based on the popular open source XTide for Unix.
XTide's predictions do not incorporate the effects of tropical storms, El Niño, seismic events, subsidence, uplift, or changes in global sea level.
You may want to check out more software for Mac, such as Dwarf Fortress, touchtheSky or Weather Plus for the United States, which might be similar to XTide.
