Good morning,
I have a problem with both Arduino Mega and Arduino Uno. Till yesterday they was recognized by my mac (macbook late 2009), but today i can not find a serial port to upload the sketches. What can i do to solve this problem? The devices are not recognized neither in the system information, so i can not do anything.
Thanks in advantage
Have you tried a different cable or USB port?
Thank you for the answer,
yes i tried 3 different cables and all the usb ports on my mac but it doesn't work with no one of these.
