Erased hard drive Reinstalled OS but automatically connected to network after set up
Hello Everyone,
on my 2017 iMac I erased the HD and installed the OS since I'm selling it, I did go through the setup after the OS was installed and basically skipped all the setup features including connecting to the network ( I choose "Skip this Step/set up later") but once the set up was completed the computer was automatically connected to my network and connected to the internet.. How can this happen if I erased the HD and reinstalled the OS? (actually did it twice) and both times it automatically connected to my network. I really don't mind but I just want to make sure that all my information on the computer is erased.. is there a better way to erase everything? used disk utility Thank you
