Failed to connect to ESP32: Timed out waiting for packet header

[NateOlivieri]

Hi everyone,

I have configured my ESP32-WROOM following this https://esp-idf.readthedocs.io/en/latest/ on my Mac OS Yosemite, late 2011.
I also have installed the driver that i found at https://www.silabs.com/products/develop ... cp-drivers to see my ESP on USB port because the newest version of these drivers doesn't work with my mac.
When i make flash on my project, i see

Flashing binaries to serial port /dev/cu.SLAB_USBtoUART (app at offset 0x10000)...
esptool.py v2.3.1
Connecting........_____....._____....._____....._____....._____....._____....._____....._____....._____....._____

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
make: *** [flash] Error 2

I have try to change USB cable but this doesn't work too.
I never flashed this board with this Mac and with other PC everything work.
Perhaps any passage that i forgot in the installation/configuration? I followed step-by-step the guide.

I wait your hints,
Thanks to Everyone for the attention.
