avrdude: ser_open(): can't open device "COM1": No such file or directory

avrdude done. Thank you.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
if any one knows that this means and how to fix it will save me money that i have wasted.
And also i would like to change COM1 for the script editor, and again using a mac

avrdude: ser_open(): can't open device "COM1": No such file or directory

The problem seems to be that you have not selected any port (in tools -> port), so it tries using the default COM1 port (which is valid only on Windows). If the tools->port menu is grayed out for you, the IDE cannot find any serial ports available, so you are likely running into a driver issue (but I'm really not sure how that works on OSX, I was under the impression that the Arduino boards serial drivers worked out of the box). Is this an official board?

In any case, this does not look like an IDE bug to me, but a problem in your setup. For help resolving those, we recommend using the Arduino forums, keeping this bugtracker clean for actual bugs and feature requests. I'm closing this issue (but there can still be comments left if needed).

I had the same issue.

I went to tools then port and then selected usbmodem 1421 and it worked
