I recently decided to set up family sharing with the other members of my household on our iPhones, so we can see where we all are. However, both of my Macs also show up on their devices, with the option to erase or mark as lost. Is there a way for the macs to only show up on my device? I would rather not share the location and status of the macs with them, especially with the option to erase. This applies to an '08 MacBook running 10.7 Lion and a '10 Mac Mini running 10.13 High Sierra. Thanks!
