Portrait mode depth of field editing on Photos for Mac - Big Sur

Thank you very much for your quick reply.

I do have an older iMac (maxed out at High Sierra) running Photos version 3 which I'm guessing does not support the portrait mode editing feature. Understood about sharing the photo dropping the depth map. I will try another method of transfer to my dad's Mac and see if the editing options show up.

Léonie,

After reading your reply, as a test on my iPhone I texted a portrait photo to myself. I saved the photo from the text message to my photos. While the original portrait photo in my photos has the depth map information and the aperture information can be edited on my iPhone, the same photo saved from the text message does not contain the depth map information and no portrait editing tools are available on my iPhone. Per your explanation - this answers the question as to what is happening with the file transfer to my dad's iMac via text and other sharing methods - thank you. I am working on the usb - zip transfer to my dad's iMac just to see if it works.

Thanks again - I really appreciate your help in understanding what was happening.

John
