Hi,

Never used a Mac with the printer but some rules are common for all kind of OS :

  • You need a FTDI driver.
  • When the printer is connected you can see a new serial port available (number of the port may vary but it’s one that you don’t see when the printer is unplugged from the USB port.
  • The baud-rate MUST be 250000 bauds in order to get the printer responding.

You can try to install FTDI for 32 bits….
But in repetier you can’t choose port-com 70 on Mac it doesn’t exist
You MUST choose yusb-serial or something like this, i’m not on my Mac actually
i don’t remind me exactly what is write, but i’m sure it’s something like this

I don’t know about Mac either, but certain linux distributions do have issues with 250000 baud rates. If you cannot get it working with what other people suggest here, please set your the baud rate in your marlin configuration (the firmware, see here) to 115200.

Got the software running and connecting without issues on OSX 1.9.1 - it definitely works!

Be sure to install the right FTDI VCP driver (2.2.8 X-64 64-bit) and to select the right baud rate - it’s not 25000, but 250000.
The serial port is not named “COMxx” under MacOS - as mentioned in the last post, be sure to select the right port. Depending on what else you have installed on your mac, you should only see a few ports in the list - the other ones being most likely bluetooth-serial ports - and should be able to identify it easily.
