My issue was mostly mitigated by setting fullscreen resolution to 1152x720@60fps. It allowed me to restore better graphics.
Playing stable Minecraft v1.13 with minimal graphics on MacBook Pro (Retina, 13-inch, Early 2015) macOS v10.13.6 (17G65) even discharges my battery when it's 100% and charging. That happens when server is running on another PC.
