I have the Mega2560 R3. I had it working fine on a PC. No longer have that PC and have installed the software on my MAC Laptop. Software installed OK. Software sees the port of usbmodem1411. When I ask for board INFo it comes up with BN:
Arduino Mega or Mega 2560 VID: 0x2341 PID: 0x0042 SN: 85735313233351E0XXXX
This is the message when I upload...

It is still running a sketch that I loaded previously and I can see the results in the serial monitor so some sort of comms is happening!
I have turned on VERBOSE for uploading and have tried a few programmer modes.
Anyone any idea what the issue is?
Thanks in advance Mat
