For some weird reason my partner's iphone safari history is showing up on my macbook's safari? Only my phone is connected to my macbook (for imessages and icloud), so I can't understand how his history is showing up when mine isn't? How is this possible? He has used his phone as a hotspot before and logged into his icloud for itunes once but his history has been showing up way before then? Please help clarify to stop this!
