Got a clean bn build on the big mac, clang16 with not too much boost hassle. The node runs as expected, with about the same behavior as the linux node. It's not stalling, but using very few resources. So I've got three working test boxes, with running nodes on each, for Windows-11, macOS-15, and Ubuntu-24, and prebuilt versions of Bitcoin Core benchmarked on all but the Big Mac, so will fire that up now.
