Hello everyone. Please can somebody explain me what exactly should I do to reinstall openocd on my mac… I’m trying to solve the same problem with *** [upload] Error -6 when uploading to my Arduino Nano board…

Ok, I’d found how to reinstall openocd, and this solved the problem, thanks for this solution!
