avrduderc

I just received my brandnew Arduino UNO Wifi Rev2.
Had problems with non genuineArduinos on my Apple MacBook Air so I deceided to try the genuine now, to fix this.
I connected it via USB and the green LED went on with the yellow LEDblinking I installed the 1.8.8 IDE from the ARDUINO Webside and the dribers to be able to select the USB Port.

mEDBG CMSIS-DAP:

  • Produkt-ID: 0x2145*
  • Hersteller-ID: 0x03eb (Atmel Corporation)*
  • Version: 10.00*

  • Verfügbare Stromstärke (mA): 500*
  • Erforderliche Stromstärke (mA): 100*

However, when I try to upload the BLINK Script from the example list. The upload fails:

User configuration file is "/Users/xxxxxxxxxx/.avrduderc"

    avrdude done.

Did some research on the internet but could not find a solution which I could simply use.
(only some suggestions which seem to go quite deep into the LINUX of my MAC (Terminal Sudo etc)
why i this not pulg and play as I was expecting when buying genuine products. I am really annoyed.
My Mac Book Air is running IOS High Sierra ver 10.13.6

When you disconnect the board, does /dev/cu.usbmodemFD112 disappear from the tools -> ports menu in the IDE? If not, you have the wrong com port selected.

User configuration file does not exist or is not a regular file, skipping

That's not an error.
