Debug Issues in Mac OS X
It’s normal that you don’t find the UDEV things on Mac os, they are only for Linux os.
I don’t know if homebrew has installed enough stuff for stlink for SW4STM32.
Does it declare Stlink V2 and V2-1 ? They don’t have the same USB PID.
Did you create your project with the project wizard selecting the F407 disco board (which embeds an STlink V2) ?
Or you have created a custom board (selecting STLink V2 or V2-1) ?
If you have a project selecting an STlink V2-1 but an STlink V2 on your board, in v1.10.0, it should work anyway.
But it will work only if the 2 USB PIDs of the 2 STLink versions are declared.
I don’t know if there is a change in Mac os Sierra for USB drivers ?
The previous users on this thread were on Mac OS 10.11, not 10.12.
