iMovie for High Sierra 10.13.6 ????
I'm attempting to download iMovie essentially for the first time. I'm sure my 2017 macbook pro came with it, but I must have deleted it at some point. Everything on the internet points me to the Apple app store, but the iMovie available there says "iMovie can’t be installed on “Macintosh HD” because macOS version 10.14.6 or later is required."
How do I get up to 10.14.6? I'm basically technologically illiterate. thanks.
MacBook Pro 13", macOS 10.13
