gmail setup in mail app el cap
I am sort of stuck here and was hoping someone may have experienced something similar. Am not sure of the proper names so I will try and explain my issue as best as I can.
I use gmail for my contacts, mail, and calendars. In previous setups (mavericks, Yosemite) I have unchecked email in preferences and went to add a new email account because I use an alias as my default address..even though it still checks and sends mail thru gmail. This has worked great on all devices until I updated to el cap. Because it wasn't working I deleted the account and went to set up again. When I say other mail accounts I enter my info but using the gmail login and app specific password with my default sent from address...it tells me the account already exists. When I try and setup as a google account it won't let me change the login information.
I hope that this made some sense but I am starting to get blurry playing with this all night. Any help/advice would be greatly appreciated.
