iMovie will not update
I have a 2012 MacBook Pro. I purchased iMovie in 2014. I have been working on a video project that required an update of the operating system to X El Captain Version 10.11.6 in order to use some software to convert VHS tapes to digital files. I upgraded and then iMovie would not work. It said that I needed to update. In the app store when I click update for iMovie, it just spins and nothing happens. I have a project I was working on in iMovie and now I cannot access it at all. How do I update iMovie so that it will work again with this new operating system? Thank you
