macOS high sierra 10.13.3 messages out of order
I am running macOS 10.13.3 on a late 2012 MacBook Pro 13" with Retina display. In Messages two old message threads stay pinned at the top. I do not want to delete these important threads. All other message threads show chronologically correctly. These message threads are displaying correctly on my iPhones. Thanks in advance for any help with this.
MacBook Pro with Retina display, macOS High Sierra (10.13.3)
