Why is edit greyed out when I select a live photo on my Mac?

Could you give us a bit more information?

• How did you receive this "Live Photo?"
• How was it imported into Photos?
• What makes you think that it is a "Live Photo?"
• Do you see this

in the upper left corner?

• Does it move like a Live Photo?
• Does this show up in Photos' Media Types>Live Photos?
• Does this editing failure occur with other Live Photos, or just this one?
• What do you see in the Info window-- how large is the file, for instance, and what camera was used?

Let us know…
