Topic: Arduino Uno, Mac OSX. "avrdude: stk500_recv(): programmer is not responding" (Read 1 time) previous topic - next topic


I changed couple days ago to a new Mac (Mac OS X 10.9.1) and when plugged in the Arduino Uno (that was working on the old Mac) started to show some errors when uploading the sketch. I checked other topics and troubleshooting but nothing helped. The most interesting thing is that on the old Mac Arduino IDE (v 1.5.6-r2) is uploading the sketch without any errors but on the new Mac (with the same Arduino IDE version) I get this:

Code: [Select]

Sketch uses 1,116 bytes (3%) of program storage space. Maximum is 32,256 bytes.
Global variables use 11 bytes (0%) of dynamic memory, leaving 2,037 bytes for local variables. Maximum is 2,048 bytes.

What could be the problem ? Thanks.
