1. Install the Driver (FTDI USB Serial Driver)
Download link:http://www.ftdichip.com/Drivers/VCP.htm
2. Download Repetier-Host:
Link:https://www.repetier.com/download-now
Open Repetier-Host, choose correct port and Baud rate(115200) in "Pinter>Printer settings".
Note: the baud rate, usually it is 115200 for the Mac, so you need to make sure the baud rate in the firmware is the same value too:

// This determines the communication speed of the printer
#define BAUDRATE 115200

And if that's not gonna work, you can try 250000 and other values, just make sure the value in printer settings and firmware are the same!
If you are not sure which port is correct, unplug the USB cable, then plug it again, the new port name in option of "Port" is the one. 3. Download Arduino (This is a zip including Sanguinololu and Mega2560, so you don't need to do anything else like Windows):
http://www.geeetech.com/wiki/index.php/ ... or_Mac.zip
Unzip the file after downloading.
The process of uploading the firmware can be referred at:

The instructions for Repetier Host for Mac show a "Manual Control" tab, but on my copy there is not a manual control, that tab is labeled "Print Panel." The screen it opens is not the same. I found out how to turn on and control the temperature for the extruder and build bed, but there are no arrows for testing the motors manually. I did get the motors to run by pushing the various axis buttons, but could not control off as well as on and my motors did not run well at all (froze while on), so I hit the emergency stop so I would not burn a motor up. It would be nice to have instructions that match the Repetier Host for Mac (it has either changed or I have the wrong one, but I downloaded it from here). I can see where the arrow keys would be nice for testing the motors, but my version of Repetier does not have them.

You can download the latest repetier for MAC in it's official website.

Hi,
You can check the version of your GT2560 board,if yours is RevA+,you need give it a 12V power first then connected it to your MAC.

HI

I can confirm that the board GT2560 is Rev A, not Rev A+

I have turned everything off and on, again, powered on first the printer, then plugged in the USB to the Mac. Result no change at all.

what else should i try, Please?

thanks
Nick

Hi,Nick

Hi,
