[solvespace] u6006 commented on issue #298: Didn't find this issue when building on another Mac with OS X 10.12.x, so it might be the combination of Xcode (v9) and OS X on that Mac. Considering this, I would say it need to be documented since some Macs might see this issue. https://github.com/solvespace/solvespace/issues/298#issuecomment-339050240
