I received a tip that a firmware update of Nikon's WT-4 Wireless Transmitter is due in the next week or so. It seems that the last version had problems transferring profiles to the camera when using the latest Mac OSX (10.6.4).
Nikon's Wireless Transmitter WT-4 enables image transfer and camera control from a remote computer. The connection between the computer and the camera is done via USB cable or by using Nikon's remote-control software Camera Control Pro 2. The current version of WT-4 is 1.1.4.
