To connect Android devices (like ST16) to MAC you need to install "Android File Transfer". You have access to FlightLogs, Missions, , screenshots and so on. The FPV videos are only for logging, not usable for video processing. The "real" videos are stored on the SD card in the camera.
Of course you can put the SD card in the ST16 and access the videos from there if you not have another (better) card reader.
