The feature you are talking about is called ‘Animated Zoom’ (it’s Mac only feature).
It is turned ON by default on Mac machines having a GPU card with a compatible monitor attached.
Check the Document Name in its tab – does it say ‘GPU Preview’? If not, press Shift+E to switch to this mode.
Also, check under Preferences > GPU Performance and see if ‘Animated Zoom’ is checked ON. It should be enabled for this feature to work.

Thanks Ravi, but once I go into the GPU Performance settings the checkbox to enable is greyed out...Thomas shared this idea ·
