I take photos with my new Iphone 12 mini, and download them onto my Imac. When I go to oepn them in Photoshop I get the error message, "Could not complete your request because an unknown or invalid JPEG marker type is found." I am running Catalina 10.15.7. I can open other files like png, etc. I get around this problem by screenshotting them as a png. Do I need to update my operating system? How do I fix this?
Thank you! I contacted Apple and THEY didn't even know about HEIC! Yes, that is the problem. Thank you for the solution. Also, I found you can change the setting in the Iphone so it takes jpgs instead of HEIC. This is what I did. Apparently, HEIC saves space, but I don't need that.
