How to copy/transfer iMovie projects from older iMac hard drive to new iMac
I have removed the hard drive from my older (late 2009) iMac and placed it in and external hard drive enclosure. It is now connected to my new iMac with a USB type connection, and I can open iMovie on the old drive and see the projects I would like to transfer/copy to my new iMac. I tried the procedure recommended (by Rich and Apple) whereby I create a new library, go to Projects and select the project I wish to copy, touch the icon next to the name of the project and "move" the project to the new destination. The problem I am having is: when I touch the icon (...) next to the project name every thing on the list of choices is highlighted EXCEPT "copy to library" and "move to library".
So now I have no idea how to copy my projects to my new iMac.
Any help would be greatly appreciated, thanks.
iMac (Retina 5K, 27-inch, 2017), macOS High Sierra (10.13.6)
