Let's not sugarcoat it: livestreaming on Macs tends to suck. Even if you're not streaming games, there's a dearth of high-quality broadcasting tools to add a professional level of polish. Now, however, you shouldn't have to struggle. Streamlabs has released an open Mac beta of its version of OBS that delivers the alerts, overlays, audiovisual controls and chat management that many streamers take for granted. It'll handle familiar services, too, including Twitch, Mixer, Facebook and YouTube.
