Preview in iPhoto not working after editing the picture
My photos normally pre/view in the Photo app. However, change occured after one of recent system updates. If I edit/adjust a picture, it no longer previews and I can view it only in edit mode.
This problem applies to both our comps - one with Catalina and the other one with Big Sur.
I have already changed the photo card in my camera (SDHC) as well as the card reader, but the problem persists.
Thanks for help.
