Messages not saving conversations
A few weeks ago my late 2011 Macbook Pro running High Sierra 10.13.6 had an issue with Messages where it stopped working and would freeze anytime you tried to access anything in the application. I was able to fix this by deleting files out of Messages folder under Libraries. It worked perfectly for about 2 weeks. Now, while Messages works, it wont save any conversation history after a reboot. Any ideas?
On an unrelated note, it seems the volume of the system has decreased. I used to be able to set the volume around +/- 50%. Now it seems I have the volume set around 1-2 "squares" below max. I have a feeling it is hardware given the age of the system, but never hurts to ask.
Its probably time to upgrade to a new model, but this system has given me many years of reliable use.
