Photo library heic in Sierra and Big Sur
We just installed Yosemite on a 2012 MacBook Pro so we can run a 32 bit application (Final Cut Pro 7). Our photo library in iCloud contains many photos in heic format that do not work on Yosemite. Since we can't upgrade the os on that computer, is there any way to convert the photos in photo library to jpg?
I know I can export them as jpg and then import them again, but that gives me thousands of duplicate files. Any suggestions, please?
MacBook Pro 13″, macOS 10.15
