Since upgrading to Mohave I have noticed a problem with image file thumbnails: most of the time I see a generic thumbnail for the file type (JPEG, PSD) - not the image itself. So I can’t remember what a lot of these images are unless I open the file! Anybody know what’s causing this? A Google search indicates that some people fixed the issue by deleting Sketch or a Google app of some kind, yet I have neither of these.
