I know this has been asked before but I keep getting that error message and I tried to download the driver like suggested in the other threads but nothing has changed I restarted the program the board(mega 2560) and deleted and download a new version of Arduino nothing. I am using a mac 10.13.2 with the newest version of arduino. am i installing the wrong driver?
What exactly is the error? When does this error occur? More info is needed.
Please do this:
