I'm using 2018 15'' macbook with Catalina os, I'm trying to play a video at 1.5 speed, but + ➡️ in quicktime player only allows me to play it 2x or 5x with no sound, however this post indicates it can play at 1.8x with sound, I checked apple documentation and found 'Fast forward' option by force touch pad, but I can't figure out how to do it, please help thanks!
