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.

I've used FTDI devices a lot, and never had this problem.

To find the version number:

  • plug in the FTDI device (Arduino)
  • click the apple icon -> about this mac
  • click "more info"
  • find "extensions" in the "software" section on the left column ("contents")
  • find tte FTDI in the right pane.  The version number will be listed.

I'm running 2.2.14 on os X 10.6.4 at the moment, but I've never seen that behavior in years of os X and FTDI driver versions.

I removed the old drivers and reinstalled it again...

Currently running FTDI 2.2.14 on os X 10.6.4 for both the Arduino FTDI and my USB to Serial adapter (FTDI) ...

Will pull out the USB with Serial monitor running, let see what happened ?


Phewww... I survived the crashed....  smiley smiley


I think I had installed an older FTDI driver for my USB Serial adapter that was not properly uninstalled before today....

No more crashed when I pull out either of the Arduino or USb Serial adapter while connected..


Thank you for the replies..

Apple say don't do that with an active, communicating device.
