All my attempts at capturing a screenshot using the Sorter have produced nothing but an image of my Mac wallpaper. Am I perhaps doing something wrong?
Which version of macOS do you use and what exactly did you try?
You need to allow Screen Recording permissions for DEVONthink in System Preferences > Security & Privacy > Privacy.
Chose Screen Shot icon, Chose selection, Selected your response as a test, then the preview shows only my wallpaper, not what I selected and, if saved, the saved image is that of my Mac wallpaper.
I was fairly certain I had changed that Privacy setting twice in the past but at any rate I checked it again this morning and fixed it. Now all is well. Thanks for putting up with me.
No problem at all!
