I tried AirDroid 2 which actually works quite well if you are looking for a wireless solution, however it is very slow if you have a large amount of data to transfer. ( NOTE: I am running OSX Lion 10.7.4 and Galaxy S3 has Android 4.1.2) So I was trying to connect my wife’s Galaxy S3 to my Mac so I could download all her pics and videos, but was having quite a difficult time getting the phone to connect via USB cable.
