version of IMovie, which has a "last-modified date" of today. There is also a folder of iMovie 9.0.4, but it shows last activity in April 2014. The current version's "Get info" says it is 10.0.8.
I just updated my copy also after receiving an update notice from the Mac App Store, and the "About iMovie" still says 10.0.8 even though it in fact downloaded and updated.
