Can't drag images into text messages
Hello Mac people, this problem started yesterday. I am on my Macbook Pro all day every day, and I didn't make any changes that I know of. OS is up to date - Tahoe 26.2. Wifi is excellent.
When I drag an image (jpg, png, heic) into an iMessage, I get a box with the filename instead of the image, and it says "error - not delivered, message failed to send". Text-only messages are no problem. I tried restarting and shutting down, but no change. What to do????
MacBook Pro 16″, macOS 26.2
