.Looking for EBB.
Asking the EBB for its firmware version:

Firmware update may not have succeeded.
I haven’t seen this particular set of error messages before. My first impression is that it looks like it could be an issue of access permissions (though that’s unusual on a Mac) or the port being busy.
A couple of things you might try:
* Unplug the AxiDraw from both power and USB, then connect it by USB alone, ideally to a different physical port. Then try running the updater again.
* Restart the AxiDraw into “bootloader mode” by unplugging both power and USB, then holding down the Pause button while connecting the USB cable. Release the button. That should put the LEDs into a rhythmic “heartbeat” pattern, indicating that it’s primed for bootloading. Then, try running the updater again.
* If those don’t work, try again after restarting the computer.
