I'm using the arduino ide on Mac os with arduino nano.
My code is fine and was uploading fine on my boards a while back, but now when i upload i get an error that the port is busy.
I've tried deleting and re-installing the ide aswell as downloading the CH34x package which i have seen suggested on other threads.
I have noticed that the arduino is producing to ports for the board
which has not happened before and may be the cause of the issue.
Any suggestions greatly appreciated.
This is the error message
