OpenBench Logic Sniffer is a cheap, open hardware logic analyzer that used to be available to purchase through Seeed Studio.
The software that goes along with it has been in maintenance mode for a while, and the published DMG no longer works correctly on modern macOS (at least 13.1, but probably older than that too)
I have no idea whether or not I set the dependencies up right, and I've no doubt that my formula isn't efficient, but it seems to work for me.
