Unable to find Espressif esptool on your system...

[Yutao-Jin]

First of all, MPY Jama is amazing!!!!

when I use the firmware tool on the MPY Jama, it shows me "Unable to find Espressif esptool on your system..."
even though I have followed the instructions to install the esptool, both through the pip and home-brew
I'm using a MacBook pro m1 and on macos 16.0

you need to add it to your path:

export PATH="/opt/homebrew/Cellar/esptool/4.6.2_3/bin:$PATH"

Hitting the same issue on M1 Mac Ventura. Setting the PATH variable as suggested does not resolve the issue. PATH works a bit different for MAC in that only the processes started from shell will inherit the value. Applications launched in any other way do not.
While launching the app from finder gives me the issue not finding esptool, if I launch the app from the terminal, using "/Applications/ESP32\ MPY-Jama.app/Contents/MacOS/ESP32\ MPY-Jama", works correctly due to the path setting being present.
Suggestion is to add a configurable parameter to the Mac version of the app in which to set the location of esptool.

Same problem for me - MPY Jama can't find the esptool but it is installed and in my path. As @coyte mentioned - starting from terminal esptool is found
