Second this.
I have a fresh install of high sierra on a mid 2014 MBP 13" with an old walnut Monome 128 on which I did the bus power mod. The monome is showing up in terminal (/dev/tty.usbserial-m128_100) but no go in max or Mark eats.
I think it’s a serialosc thing, but not sure how to test:
The 1.4 pkg seemed to install the serialosc binaries here: /Library/Application Support/Monome/serialosc.bundle/Contents/MacOS
And homebrew installs them here: /usr/local/Cellar/serialosc/1.4/bin
Homebrew version just crashes every time I try to run it though, so… no idea. (segfault 11)
I’ve uninstalled and stopped the pkg installed one and am now fiddling with homebrew, but would love advice. Thanks!
