Mail - iCloud account aliases missing, window freezes
Since upgrading to El Capitan on my MacBook Pro, my mail app doesn't show me all the aliases I have setup on my Apple ID. On my iPhone, everything appears just fine with the same Apple ID.
Additionally, when I try to manually add the aliases in Mail > Preferences > Accounts, the window will freeze and pressing OK and/or cancel has no affect. The only to get out of it is to force close mail.
Anyone else having issues? Any suggestions?
MacBook Pro, OS X El Capitan (10.11)
