I've been through the FAQ and posts regarding this, but can't quite get it all to work.
I'm using Arduino 0004, and I've downloaded & installed the latest Intel mac USB drivers from FTDI's site, and run the "mac osx setup" script, all seems to run well. I've checked in /dev to see that the driver is there and owner is root, and it sure enough shows up in the Tools menu when plugged in.
But, I can't get the IDE to talk to the board for love or money. "Programmer is not responding." presing "reset" right before the transfer doesn't help. Sometimes I see the rx/tx lights flash once or twice, but never a successful transfer.
(I tried 0005 but it won't launch; read the posts about that too, but thought 0004 should work..)
