Zephyr Workbench, a VSCode extension to manage Zephyr on STM32.
It enables users to easily create, develop, and debug Zephyr applications.
Main features:
Install host dependencies.
Import toolchain and SDK.
Create, configure, build and manage apps.
Debug STM32.
You can directly download it from the VSCode marketplace

I should mention that it is also obvious from the console output that the debugger is successfully communicating with the discovery board STLink, and is also successfully ‘contacting’ the target MCU, so I think it’s fairly safe to say that this is not a matter of mac (in)compatibility.
