Unable to Open Backed-up iMessages from External Hard Drive
I have a 1TB external hard drive that I use to back-up my Macbook air. I recently was trying to find an old conversation I had and did a search on the external hard drive. I tried clicking on the message to open it, but it won't open. The conversations used to open in the Messages app, but they do not default to that app anymore since updating to BigSur (I am running the most up-to-date version). I tried searching for Messages and selecting the app as the default to open the conversations, but it gives me error code 13. Looked that up and tried making adjustments, but have hit a wall. Any help of ideas?
MacBook Air 13″, macOS 11.1
