Building on OSX

First you have to replace the linux toolchain:

download the mac toolchain from this page
rename the linux toolchain: mv xtensa-esp32-elf xtensa-esp32-elf-linux
untar the mac toolchain: tar zxf ~/Downloads/xtensa-esp32-elf-osx-1.22.0-61-gab8375a-5.2.0.tar.gz

Then install the CP2102 usbserial driver

In the sdkconfig file change this line:

CONFIG_ESPTOOLPY_PORT="/dev/tty.SLAB_USBtoUART"
