Hi David
You have posted this question before in the last couple of days to which I gave my best reply.
The Admins & Mods don't like double post and may choose to merge these.
Before you do anything, it will help you if you Open Finder > Preferences > Sidebar and make sure Home Folder is checked. This will make it visible in your sidebar. Easier for later on.
Now, Open Photos app; choose the photo or photos you wish to export. Then File > Export (choose unmodified original or just Photo).
Then choose your export settings, then Export.
Now, navigate to your Home Folder (in sidebar) > Pictures.
That's it.
Is this what you are doing?
As I explained in the other thread, an Export Error - 1 can mean that there are permission issues and you did download and then remove some Google and/or other apps which I don't recall. They might have messed things up, maybe.
