Can't upload code to Arduino board on Mac I'm using a MacBook Pro with 10.13.6, an Official Arduino Uno Board and Arduino 1.8.13 IDE.
I'm having troubles uploading code to the Arduino Board.
I have 5 ports available:

dev/cu.-AvnetaSPPPort
dev/cu.Bluetooth-Incoming-Port
dev/cu.SRS-BTX300-DataInteract
dev/cu.RS-XB41-BluetoothSeria-1
dev/cu.UEMEGABOOM-LWACP-2

I'm not sure if any oh these ports is the correct one but I've already tried all of them and I keep getting errors like: &quot;avrdude: ser_open(): can't open device &quot;/dev/cu.-AvneraSPPPort&quot;: Resource busy&quot;
Some weeks ago I was trying Arduino on the same computer and all went good but right now I can't get it to work, however I don't remember wich port was selected.
In the IDE the board I have selected is &quot;Arduino Uno&quot; and as Programmer option I have &quot;AVRISP mkll&quot;.
Does anyone know how to solve this?
I finally solved the problem.
Although the Board has no information about being a clone (it only says &quot;Uno&quot; and was provided by the faculty so I think it is official), I was looking on the web for similar problems and found out that installing CH340 Driver was working for a lot of users.
So that was what I did and now it works like a charm.
