ESP32 not showing serial port after Mac installation

[danthegoodman1]

Hardware:

Board: ESP32 Dev Module
Core Installation/update date: Yesterday
IDE name: Arduino IDE
Flash Frequency: N/A
Upload Speed: N/A

Description:

So I am using an ESP32 Dev Module, and a 2017 MBP 13" and after following the arduino installation tutorial for the ESP32 I have the boards, but the ESP32 dev module does not show up as a serial port.

Any help would be great, thanks.

Have you installed the serial port driver?

Please run this command ls /dev | grep tty and paste the result here.

I have not installed any serial port drivers (I think?)
Here is the absurd output:

Your board might use USB to UART. You'd need another driver for that.

Will try that tomorrow and drop in here how it goes!

My ESP32 didn't show up on my MAC either until I installed that driver.

So it doesn't seem like it is installing them on my laptop. The files from the uninstall script are not there.

So it doesn't seem like it is installing them on my laptop.

For MacOS X 10.9 and 10.10, see the folder called "Legacy MacVCP Driver".
It may also help if you drag&drop out the file "Silicon Labs VCP Driver.pkg" to any folder (e.g. Downloads) and start it from there

Well, it crashes my OSX 10.11 machine when I try to upload my sketch (filed a separate issue awhile back, but no answers: #983).

[mistergreen]

If your OS X is crashing, it could be because of the USB driver. My OS X crashed when I plugged in my ESP8266.

Hi danthegoodman1. I almost met the same problem with ESP32. Did you figures it out now?

[JohnGEyles]

FWIW (I think it's mentioned in the other thread I started), mine worked when I used one of the USB ports on the back of my Apple monitor (a hub there, presumably) instead of the ones on the front of my Mac Pro tower. I guess this wouldn't apply to the OP's Macbook Pro though. Maybe try it with a powered hub ? Try a shorter thicker cable ? Add a battery to the ESP32 so it has plenty of power ?

Goog that "richardfuchs"

Hi, I have the same problem too. downloaded the recommended silicon labs drivers for usb to uart but still no luck. My Mac OS version is High Sierra 10.13.5.

Does anyone have the same problem too?

[Chris2060]

@bakzs Yeah I do have the exact same problem on my macbook pro... I have a Esp 32 Devkit V1 and installed the driver from espressif and the recomended one above, but I still cant see it in the arduino IDE. Im sad...
Someone any idea how to fix it?

[JohnGEyles]

Try the various USB ports, try a different cable, try a USB hub ...
