my macbook is connected to my sisters phone even though i am on a different apple id
When I text my mom on my Macbook air, it comes up as if my sister was texting her under her phone number, when I was really texting her through my email. We are set up on different iclouds and i have tried everything to make sure we are not connected through facetime or messages and it has not worked.
MacBook Air (2018 or later)
