Beim Hochladen des Sketches ist ein Fehler aufgetreten

the driver maybe OK. the serial monitor is working well.
i think the problem was pointed here:
Cannot run program “REMOVE/bin/avrdude”
But, where can i configure or where should i place avrdude?

I hope you can under stand my problem and have a idea for trouble shooting.
best regards
Olli

Typically this sort of issue can be fixed by deleting /Users/oliverwiemer/Library/Arduino15 (or you can just rename the folder in case you want to recover it later.

That folder contains your preferences.txt file and also any hardware packages you have installed via Boards Manager so you would need to reconfigure via File > Preferences and re-install any Boards Manager hardware packages after doing this.

Please be very careful when deleting files from your computer. When in doubt back up!

thanks a lot. i will test it at night!

Great Thanks. it works!!! Thank you for the fast help!
