The Suunto provided software is not compatible with a Mac's OSX. It requires Windows, which can be operated on a Mac via Bootcamp or an emulation app (like Parallels). As for extracting with a Mac for use with another program, there is no indication that it is possible either. The only write-ups to date have been to use a Windows-based machine (or an OS emulator or Bootcamp) to extract the information and then to port to a Mac program. While USB is the connection, the software still must know the protocol to retrieve the information from the X10.It's unfortunate that Suunto appears to be unwilling to support the Mac platform. Based on various forums this has been a point of contention for many. Someone did build a third party app for downloading some of the Suunto dive watches to a Mac, but no such luck for the rest of us.
