When you download iMovie, the App Store will decide which version to download (it won't let you download a version that your system can't support)
But will I get to choose which version I want - assuming there are multiple versions compatible with Sierra?

If I move forward with this, it will be on macOS Sierra.
Not sure what version is available to me?
