Programmer not responding

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:

  • File > Preferences > Show verbose output during: > compilation (uncheck) > upload (check) > OK
  • Sketch > Upload
  • After the upload fails you’ll see a button on the right side of the orange bar “Copy error messages”. Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).
