I had the same problem.
I referred to joshrhyked's post, and I succeed burn with the following steps.
-
Start Terminal App.
-
Install homebrew.
Please refer to the installation on the page.
https://brew.sh/ -
Install python3
Please type the command.
$ brew install python3 -
Put a symbolic link
$ sudo ln -s /usr/local/bin/python3 /usr/local/bin/python -
Start M5Burner on Terminal
$ /Applications/M5Burner.app/Contents/MacOS/electron-m5burner-v2-eletron
best of luck to you!
