Most software these days consists of several small programs and libraries that form a whole and Navigate UC Mac Client is no different. The Versions page lists the version used for each component part that makes up Navigate UC Mac Client. This information can be used to track down any rogue element that perhaps hasn’t updated correctly or to provide clues to a problem’s cause.
