An app in the Mac App Store allows you to edit photos from the Photos app using any editor on your Mac. By installing this app and enabling its extension, you can jump from Photos to an editor of your choice and back again without creating any temporary files or wasting time.
You can also watch this video at YouTube (but with ads).
Here’s a link to the External Editors For Photos app in the Mac App Store.
I wish there were an extention to enable at least video smoothing without creating a new file with the date and location altered.
Selecting an external photo editor was built into iPhoto. Editing in Photos has been driving me buggy. What a great tip! Thanks a million. (For years, I have been using Photoshop Elements for editing). THANKS again.
Using Pixelmator (other than Acorn) doesn't seem to work. It won't save It to Photos.
Thanks In advance.

Robert: You may want to contact them about that. Pixelmator already has their own extensions, but they are only for special features. I'd like to see them offer their own full external editing extension.
