The warnings about MacOS are mostly being cautious, as I don't think anyone actually runs it in production. I work with open source Hack code a lot, and I almost always use the MacOS binaries instead of Linux for development. For my workflows, it's more that there's two major missing things - I'm not seeing random issues. The big things are: - a lot of the profiling features are Linux-only - the mcrouter extension is Linux-only. If you're using memcached, this extension is useful even without mcrouterd, as it provides a true async (Awaitable) client.
