Mail problems
I've just updated my OS on my iMac and MacBook and now my mail isn’t sending on either. Spent an hour and a half on the phone to Apple support and they couldn’t figure it out and said it was a glitch with their software. He suggested I update again (!) which I did and still no resolution. ****** frustrated. Having to use my iPhone for all my emailing!
iMac 21.5″, macOS 10.13
