.heic file format

[macta]

Hi - I was holding off updating my mac to High Sierra, and I just transferred some photos from my iphone running ios11 to my mac and many files have appeared on my disk in the new .heic format. I was hoping that Acdsee mac would be able to view those - however it doesn't seem like it does. Do I have to run high sierra for Acdsee to view them - or isn't it just a file format that the app needs to know about. OR does it just not support this format at all?

thanks

I would think it's that they don't support the file type. You can convert it to dng thats what I do with gopro raw because they don't support it
