cannot download new MacOS or iMovie
when I try to download iMovie, I get this message: iMovie can’t be installed on “Macintosh HD” because macOS version 10.14.6 or later is required.
when I then try to download v 10.14.6, I get the following message: This version of macOS 10.14.6 cannot be installed on this computer.
I'm currently trying to work on a Mac (21.5-inch, Mid 2011) with High Sierra 10.13.6
This Mac is without a pre-exisiting iMovie installed....
What do I do? Do I have any options?
Please help, I've been trying to install new versions all day. Thanks.
iMac Line (2012 and Later)
