How to find photos without location tag

In Photos on your Mac you can create a smart album (File > New Smart Album) with the rule "Photo is not tagged with GPS". This is working in Photos 2 and 3. I'm not sure about Photos 1. Which version are you using?

No, not in Photos 3.0 on High Sierra, if that is your system version. You can only find all photos without any named face, but that will include all photos without any people at all.

Smart Album and criteria "Face is not %" Since this is SQL the % works as a wildcard.

Sort of

Name - is not - %

Will show all photos with no name assigned including all photos with no people in them - there is no knows way to find all photos with only un-named people in them
