Folks i'm new here and need your help.. Mods, sorry for starting a new thread here..
I bought a used mac, the seller deleted his user account and his files before he gave it to me. Fair enough..
But im facing a difficulty of not being able to upgrade a few ios essential softwares as it asks for the login credentials of the initial time of purchase registration.
My friend also told me that if my mac crashes, i will have to login thro the same primary account to get the mac working again..
Please help what can i do to get around this?
