iMessage on Mac unable to text photos and videos

[Rachel Faith]

Bump. This issue just started for me too. On ALL of my macs. I have two mac mini 18s. Two MBPs 15 and 16. And one iMac 18. ALL with latest software, up to date.

I tried all of the things in this thread. But it is on ALL my macs so it cannot be a LOCAL issue.

This worked for me:

1. Sign out from iMessage
2. Finder, Go > Library (Hold option)
3. Locate Messages folder
4. delete everything ends with .db
5. restart the computer
6. open iMessage and sign in again
