it used to before, but i cant say if the problem is from upgrading to el capitan, or to a short lived attempt to have a 2nd log in account so i could use back to my mac with a separate icloud address. basically my mac used to start up automatically logging into my account which is an admin account but with my name. now it insists on starting up with a login screen to choose either my account or the proper 'admin' account. when i go into users & groups it says 'automatic login' and beside it is my named account. yet when i restart it asks me to login. its a real pain, not just the extra few seconds but i often find my computer crashes when using teamviewer, which i use to login from work into my mac, but i have teamviewer as 'open on startup' and a fixed password, so its not a big issue, if it crashes i wait for it to restart and then login. now i cant.
