How do I move an iMovie Project on my iPhone to my iMac?

I can't explain the difficulties that you are having. If you exported the project as a project, not a video, from your iPhone using Air Drop, then the project should be in the Downloads folder on your Mac. The next step is to open iMovie and do a File/Import iMovie iOS Projects, navigate to your Downloads folder, and import the project. Is that the procedure you are following?

Hmmmm. It seems that the trouble is on the iOS iMovie side. You might try posting your question on the iPhone forum and see if the contributors there can come up with a solution:

When I tap on the iMovie project icon on my iPhone, and then tap the share button at the bottom of the screen, I get share options that include iCloud Drive and Air Drop. For some reason my iPhone is not recognizing Air Drop on my Mac. However, when I click on iCloud drive I get a prompt that looks like this:

I can then select to share as a Video File or an iMovie Project. This apparently is not happening in your situation. You might try turning on iCloud drive on your Mac and then sharing to iCloud Drive from your iPhone to see if you get the prompts.

If it is the project itself you want to move from your iPhone to your Mac, this link will explain the process.

In my previous post I meant to say that you need to share the project to iTunes or to iCloud Drive, or share by Air Drop, so that you have a location to navigate to.

A .mov file can be imported into iMovie.

Here's a link with some more info on importing an iOS iMovie project to your Mac:

The way I have done it is to upload the iOS project from my iPhone to iCloud Drive. I then can download it from iCloud Drive to my Mac. It has to be shared to your Mac before there is a location on your Mac that you can navigate to.

The .mov file, according to the literature, carries with it all the media and edits for the project. After exporting the project from your iPhone, then, from within iMovie select to import the iOS project either from iCloud (if you exported it there) or from the Downloads folder if you exported it by Air Drop. Once you have the movie file into an iMovie project. It should give you an editable project.
