Question: Mail Failure on iMac Sierra 10.13.3
I am completely frustrated.
Mail will not connect to any of my accounts whether it be gmail, aol, or iCloud.
The only thing different from when it did is a new router but that worked fine for days after it was installed.
I have deleted the accounts and then tried to put them in again. I add the account and I am asked for the apps with which I want the account(s) associated. I then click the "DONE" box and absolutely nothing happens. And, yes, I tried to open a completely new account with the same result.
Mail continues to work on my iPhone and iPad.
iMac, macOS High Sierra (10.13.3)
