Yahoo transition issues

Hi all

i just completed the transition to yahoo and added the account to my iPhone 

however I am having trouble adding it to macOS native mail app

when I try to add a yahoo account in mail it’s inactive and looks like it’s still trying to use Comcast’s imap settings 

also now I keep getting a notice when signing into yahoo online that I need to try to log onto it with a browser or device I’ve used before 

i ran out of browsers and devices and keep getting the same errors 

can some one help me with the yahoo issue and also successfully add to macOS mail?thanks
