So my iMessage successfully logged in but he keeps signing out as in the video I inserted below, I have tried to reset the NVRAM but it doesn't work for the config.plist I have set and made a new serial number, UUID, ROM and others and also for the MAC address I have adjusted it to what appears on my Ethernet, is there any way to fix this?
