Mail app freezes when trying to connect to Yahoo
My Yahoo mail, calendar, contacts stopped synchronising, possibly after the last security update. on 7 April. I deleted the Yahoo account and tried to reattach. My Userid and password worked correctly for Yahoo, but the next step (what do you want to connect-Mail,Contacts,Calendar etc.) just freezes on the screen. Left it for hours to see if it was working in background but the only option is to cancel. I have another mail account with live.com, and this is working OK. I have also closed and reopened this without problems. I am using High Sierra - 10.13.6
