Photos High Sierra Edit Menu

I know of no way to change that list and Apple has not published how they determine what is there - what Photo editor do you have that is not in the list?

And several people have noted difficulty with using the Edit with capability - for now it probably is worthwhile investing $0.99 in the External Editor for Photos Extension for Photos which works very well and have been in use for over a year and seems trouble free

My PS C3 app is in a subfolder in the Applications folder and it is shown. However, my PSE app is not, regardless of where it is located in the Applications folder.

You might do as Larry suggested and get the the 99¢ External Editors For Photos from the App Store. This user tip shows how to use it: External Editors in Photos Are Here

In Photos 3 it's access in the Edit mode here:

Thank Old Toad. I already have External Editors and it does work fine. What I'm talking about is in Photos 3 (High Sierra) you can simply right click on a photo, and in the drop down you can choose "edit with", and go to an editor directly.

This is a really cool feature of Photos 3. It has some built in protection for a photo that was edited with an external editor. The fact that Photoshop is not on the list is a minor annoyance. I will use this instead of External Editors. External Editors was a life saver for the last couple of years until Apple came out with this new feature.

I assume that is using the $0.99 External Editors for Photos extension from the App store and not using the edit with feature - Is that correct?

No, I need External Editors mostly for DxO Perspective and Color Strokes or Inpaint.

Some applications have an editing extension, that will call the complete application. I am using Affinity Photos this way and Luminar 2018 and GraphicConverter 10. Picktorial can also be called this way, but I rarely use it.

Luminar, Affinity Photos, Graphic Converter need to be called using their extension. When I try to use them with "Image > Edit With", I will have the problem with saving back to Photos.

, but I never see anything but Preview, Color Sync and Grab.

Check, if there are upgrades available for your photo editing applications. Only applications fully compatible with High Sierra will show in that menu.

I'm seeing a few more applications in this menu.

It is weird, that even applications not meant for picture processing will show there, like TeXShop.

Affinity Photos cannot yet open photos in HEIF/HEIC format. Your wife's iPhone may be set to use the new, space saving HEIF format. Not all external editors support it yet. When I select a JPEG, Affinity Photos will appear in the "Select other" section and can be launched on the photo.

See this support document, on how to set the iPhone/iPad to use the more compatible image formats, if it is currently set to save all new photos as HEIF/HEIC:

I have Affinity Photos and there is an option at the bottom of my "edit with" list to add other apps. But when I select Affinity Photo, it comes up with an error message that Affinity Photo cannot open this type of photo. And it was one that my wife recently took with her iPhone 8 Plus.

Old Toad - Adobe Photoshop CC 2017 is in my applications folder, but it is not showing up in the the "edit with" drop down. I have to select the app by choosing "other..." and browsing for it.

I noticed that the applications that are on the list are either in the /applications/ folder or in the /applications/utilities/ folder. the Adobe Photoshop CC 2017 app is in /applications/Adobe Photoshop CC 2017/ folder. I wonder if the app needs to be located up one level in the /applications/ folder? Not sure if I can simply move the app up a level or if that goofs something up in my CC instalation.

BTW, Adobe Photoshop CC 2017 edits the new HEIC with no problem.

External Editors is still a Life saver, and I am glad it is back at the App Store. It had been pulled from the AppSTore when High Sierra came out. I am still using it more frequently than the "Image > Edit With" command, for all applications that cannot save back the edited results to Photos.

It is just that not all external editors have been updated to implement the "Edit With " protocol, and when we call them from Photos with "Edit with", they cannot save the edited photo back. If an application appears in the menu and does not need to be called using "Other" it will usually be fully compatible.

That makes sense. I did edit a photo with photoshop, and I saved, and it seemed to save the image correctly in Photos. But if I press the normal Edit button on the edited photo, it says that the photo is still being edited by another editor. It will be nice when Photoshop becomes compatible with the "Edit With" protocol.

. I can call it directly from the Edit panel in Photos as an extension.

I assume that is using the $0.99 External Editors for Photos extension from the App store and not using the edit with feature - Is that correct?

Yes it is strange. Snagit, for example, doesn't care about being compatible with Apple Photos 3, yet is shows up on the list. All I can think is that some simple editors are designed to be called from within other programs, like a shell program, where others, like PS are designed to be totally standalone? Maybe that is because of Adobe's elaborate licensing systems.

I did have success with PS. It just didn't send the signal to the call program (Edit With) that it was done and the file was closed. So the warning comes up and asks if you saved the file.

Any app that's in the Application folder or on any external HD that can edit or just open an image file is listed in that menu.
