I encounter this issue, when I pull out the Arduino USB port (FTDI) while the serial port is active, it will immediately crashed the Mac Snow Leopard ..
Anyone encounter the same issue or know how to fix it ??
How to check what version of FTDI driver have I installed on the Mac ?
Hi, this never happens with me. MacBook pro OS 10.6.4
If the serial monitor window is open then you get a disconnect dialogue box but that's about it. I regularly unplug the USB when making changes to my circuit boards.
