I've been trying to use these new versions on my PPM-based Mac, but I can't seem to upload any sketches to either my Diecimila or Duemilanove (168) oards. I can load a sketch in 0012 and upload it to the board just fine. But, if I then try to upload the same sketch (using the same settings for the board and serial port) using either 0013, or 0014, I get this error:
avrdude: usbdev_open(): did not find any USB device "usb"
Anyone know what I'm doing wrong?
