Is it possible to use Studio 2 as a plug-in or extension in the Photos app on a Mac?
I believe that Photos uses “extensions” not Plugins.
You should be able to use the option for Edit with-> Program. But, I believe that this is only JPEG format as that is created by Photos to send to the external program.
Thank you for the reply Don. It does not show up as an extension.
It wont show up in Extensions as they offer non-destructive edits but you should be able to select an image then use Edit with-> program where Photos will create a JPEG and pass that to an external application.
I found it now. Thank you very much Don. I am really missing Aperture.
