From the developer:
Flighty is a live flight tracker that allows you to monitor unlimited flights. You receive live data and weather information. However, the historical flight lookup is limited to the past 365 days. You get the actual flight route, the aircraft model and image, and the personal flight log and map.
You may want to check out more software for Mac, such as JOSM, Meander or GMap, which might be similar to Flighty.
