My mac has swapped my contacts with my sons - how do i get mine back?
My mac has swapped my contacts with my sons - how do i get mine back? I just installed latest update and when i looked for a contact all my contacts have disappeared and instead i see the few my son has - he is on my family sharing. I still have my contacts on my phone but am worried if I switch on contacts on the phone to use my iCloud they will disappear from there too and be replaced by my sons. Any ideas help gratefully received.
Mac mini, Mac OS X (10.5.8)
