Launcher using excessive system resources on macOS Catalina

XMLWordPrintable

    • Unconfirmed

      After updating to macOS Catalina, Minecraft Launcher is using excessive system resources. MacBook fan kicks on high shortly after Minecraft launches, Activity Monitor shows launcher using 99% CPU at minimum. Game is playable but fan noise is excessive and continuous. Force-quitting the Minecraft Launcher resolves issue, and I can play normally after quitting the launcher (is it SUPPOSED to stay open after launching Minecraft?) This behavior was not observed at any time prior to OS upgrade.
