This did not work for me, but a small variation of this did work
In Terminal:
defaults write com.apple.finder AnimateWindowZoom -bool YES
killall Finder
If this doesn't work on it's own, you might have to do this in Terminal too:
defauts write com.apple.finder DisableAllAnimations -bool NO
killall Finder
If you want to just do both all at once, to be safe, do this in Terminal:
defaults write com.apple.finder AnimateWindowZoom -bool YES
defaults write com.apple.finder DisableAllAnimations -bool NO
killall Finder
All of the commands are case-sensitive. Good luck 😉
