About
PackTrack is package tracking application for Mac OS X. It includes the ability to track UPS and FedEx carriers out of the box. It also includes an interface for creating plug-ins for other carriers.
PackTrack 1.0.2 adds interface improvements and adapts the UPS plug-in to work with UPS's redesigned website. Revision 2 fixes a problem with the UPS module if the delivery date is unknown.
