How do I stop my laptop from connecting to my iPhone hotspot (using same Apple ID)
My laptop network preferences recognizes my iPhone 8 Personal Hotspot (even though that is turned OFF on my phone) My cellular data drains
how can I disable / forget network from my lMacBook Air (M1, 2020)
do I have to use a separate Apple ID for each device?
The issue is exacerbated by ...
...devices with the same Apple ID have automatic access to the Personal Hotspot on your iPhone, which means that they can turn it on without prompting you for permission.
