Spotify loads and opens when iMac starts up
I'm on a late 2015 iMac OS 10.13.2. Recently (perhaps when the system last upgraded itself) Spotify loads and opens every time I turn on the computer. Wasn't my idea, and I'd like to defeat it. I have turned off Spotify's "load on startup" option, but it does so anyway. Any ideas?
Many thanks.
