All photos in Photos in my iMac do not show as available to iMovie even though Download Originals to this Mac has been checked for very long time - sudden change?
iMac 2017 1TB, v 11.0.1, iMovie v 10.2.2, Photos 6.0 Trying to make a movie with iMovie by importing a bunch of photos from my Photos library which I then just turn into a video slide show. I have done this in the past many times but a while ago. Today, while in iMovie browser section where I select Media, not all photos or albums or my albums, etc. were available, only some. It used to be that everything was available. According to Apple help, this may have changed:
https://support.apple.com/en-us/HT204669
But I'm not sure. The above states at the end:, "If you want to make all the pictures in your Photos library permanently available to the Media Browser, you can select Download Originals to this Mac in the iCloud tab in Photos preferences. When you do this, you'll lose the space-saving benefits of the Optimize Mac Storage preference."
I already have this Download Originals to this Mac checked, and I have had it checked for years - I have a large hard drive and enough space so I leave it checked, and it was before I started this movie. I use iCloud and sync to my phone and my Macbook Air. The iphone is set to use icloud Photos, and Optimize iphone storage is checked on. My Photos Library shows 174 GB that should be about right, so as I noted, enough space - 250 GB availabe on this hard drive.
So I'm missing understanding something here. How do I get ALL of my photos, and videos, in my Photos library become available again? [ I can fix my immediate problem by the steps described in the support link above, although I have not tried yet. It puzzles me why I can't get the rest]
Many Thanks.
