Mac Photos Extension: Affinity cannot be launched in (Pre 1.7) Bugs on Mac Posted January 1, 2018 The latest update hasn't changed anything for me. However, I have found a workaround. Instead of editing the photo in iPhoto, then choosing to edit with Affinity... right click on the photo, and choose to edit it with Affinity Photo. I've attached a screenshot. To help clarify the issue, this feature DOES NOT work if you: Open up a photo in iPhoto Click "Edit" at the top right Click the (...) option for editing with extensions. Choose the "Edit in Affinity Photo" option. Note: all other Affinity extensions work fine here (i.e. Affinity Develop, Affinity Haze Removal, Affinity Retouch) This feature DOES work if you: Right click on any photo in iPhoto Choose "Edit With" and then select "Affinity Photo" ----- What I'm still missing from this though, is the ability to choose a photo in iPhoto, edit it in Affinity Photo, and have all of my edits adjust and update in iPhoto. It seems with this route, I have to save a new file after I make edits. Please let me know if I'm missing something!
