Problem With Correct Serial Port

For some strange reason it seems like my serial port changed on my Mac and I’m having trouble uploading sketches to the Arduino Mega?

I’m also a little unclear of what the “Programmer” should be set at for the Arduino Mega 2560?

If you're doing an upload using serial via the USB cable then it doesn't matter. The Tools > Programmer selection makes no difference because it's not used.

I did wonder about that, still no clue why I can't upload a sketch to my Arduino though, I get some weird timeout error or some such.
