The Slow Motion effect in MacOS, which allows for animations to be drawn in slow motion, can be re-enabled by entering a command in the Terminal application.
To re-enable Slow Motion effects on MacOS, open Terminal and enter the command 'defaults write com.apple.dock slow-motion-allowed -bool YES;killall Dock'
After relaunching the Dock, holding down the Shift key while using features like minimizing and maximizing windows, opening Launchpad, or using Mission Control will activate the Slow Motion effect.
This is a fun and relatively simple trick that brings back the whimsy of earlier days of MacOS.
