TiDiGino problem with linux and mac osx

Hi, I purchased a tidigino to use it with linux and mac osx, but my model seems to work only with windows. I contacted the manufacturers, but I was not able to give an explanation. With both linux and osx serial port is recognized, but the arduino ide go in times out when loading a scketch, while working perfectly in windows. Do you know something about that? thank you! R
