This did not work also

Hi

If  you have tried to connect a smartphone to your Mac using that cable and see if you can read data 

is OK

I have tried connecting to a smartphone and the usb is okay,  the link you shared doesn’t seem to enable com port, I’m looking for com 4 as explained in the tutorial( https://rntlab.com/module-1/installing-the-esp32-board-in-arduino-ide-windows-mac-os-x-and-linux/,) or how should I go about it, apologies for the many questions I’m new to this.

Hi

Each time you connect the USB Cable, you may get a different com value …

So you need to set the arduino IDE port to that Com ie Com 7

check to see what com is for ESP32 CP210x USB to UART Bridge VCP Driver … on your mac

Hello Wanjiku,

In the troubleshooting guide, can you please try following “Step 6. COM Port not found/not available“

Does installing the drivers make it work for you?

Thanks!

Hi Rui,
I have the drivers installed and I’m using a phone charger USB, I still don’t get the com port 
 

Hello, does your phone charger has data cables? Basically, can you transfer files from your computer to your smartphone via USB? Can you try with a shorter USB cable?

Hi 
I managed to get a different USB, although now I’m getting this option /dev/cu.SLAB_USBtoUART 
Does this suffice or do I still need a COM option?

Exactly, that should be your board option, you just need to select the option that appears when you plug your board.
