So today and after upgrading to MacOS Mojave, I have noticed something very odd. At the beginning I didn't notice that detail but then I was like "Wait a second". It's about my computer's name. I have always used my real name on all my iDevices and on all my Apple account and services like iCloud and Contacts. What I noticed is that after the update (High Sierra->Mojave) the computer's name has changed from my real name to my nickname even though I have never provided to any of my iDevices or Apple my nickname. I have never modified the computers name All iDevices are named with my real name On all Apple services I use my real name In contact's under "My card" i use only my real name This is creepy! I have hey siri enabled on my iPhone, is it possible that Siri changed it because she can hear that all people are calling me with my nickname?
