I haven't heard of a way to use the native iPhoto on a Mac to import photos from the Samsung Galaxy Camera EK-GC100 to a Mac.
I've already used the Samsung Kies Mac App and a USB cable to transfer photos.
Previously: Samsung Galaxy Camera EK-GC100 Kies to Connect
I just tried transferring the photos over WiFi.
Here are the steps:
On the Samsung Galaxy Camera EK-GC100 got into Settings > Wireless and Networks.
SELECT Kies via Wi-FI
SCAN DEVICES and choose your computer.
Note: Both the Samsung Galaxy Camera EK-GC100 and your computer have to be on the SAME WiFi network.
Once you are connected, use the Kies App to copy photos over.
Note: You have to use the Kies App SAVE menu instead of dragging and dropping. That needs to be improved.
Thanks @SamsungMobileUSA for the review unit.
