I reported earlier a different method for MacOS that requires much less material to be downloaded and is closer to a regular Mac package install. It has worked fine for flashing the BLF Q8 as well as a range of Emisars.
A possible downside of this approach is that the package is not maintained, so the method might be undone by future OS updates or MCU versions. I give details of my environment in that earlier post.
Edit: I should add that this simple method is aimed at those users who want to install a given hex file, not those who want to edit the source code and compile their own hex.
