I'm wondering what is gong to happen if I send apple my 12" MacBook with no macOS installed? I was following the steps to erase and re-install macOS but now when I do command + r to get into recovery to install Catalina I get the wifi login. When I try to enter the wifi info of my router it doesn't accept the password.
