How to edit photos with HDR, HEIC or Live
I've just updated my MacAir laptop today to MacOS Sierra 10.12.6. The updates tell me there are no further updates available.
I have over 3000 photos recently taken on my new iPhone 8 with IOS 12.1 during extensive international travel most of which have come up as HDR and Live.
I now have a little white triangle in the corner of my photos with an explanation mark in it saying the photo is unsupported and I need to update my system - which I've done and can't do any further.
I have Photos 2 on my Mac Laptop.
Most of the photos also have a HEIC tag (which when I shared with a friend also came up as unsupported.)
I am unable to edit the HDR and Live photos as the editing icon is grey and won't open.
Please explain in simple language how to edit these photos.
Thanks
Vicky
