Metro 328 on macos catalina cannot upload

by remzioten on Fri Oct 09, 2020 10:26 pm

Hi ,
I have a Metro 328 that I purchased couple of years ago and I tried it first time on my Macbook with Catalina. I followed the instructions at https://learn.adafruit.com/experimenter ... /mac-setup and everything went well except I cannot upload the simple blink code to the device. It gives an error: avrdude: ser_open(): can't open device "/dev/cu.usbserial-017D37AE": Resource busy. . I tried changing the cable, reloading the drivers, changing the ports, switching back to older board versions. Nothing seems to work. I am fairly new. I must be missing something.
