macOS Sierra 10.12.6 Messages freezes
I have an iMac; (late 2015) memory; 8 GB 1867 MHz DDR3 running the latest macOS Sierra 10.12.6. Messages was working just fine for me and now suddenly it does not. I am not certain if it was due to the latest OS release or not. When I open the app on my computer, it just freezes. I am unable to click on a conversation or do anything with it. When I close the app it takes for over to close or I have to force quit the app. Help.
iMac, macOS Sierra (10.12.6)
